Yes, the dyno charts would suggest a huge advantage of the Procede over the other options. From the beginning, as I looked at the numbers from the BMWs using the various tuning solutions, I was wondering why in the world there is so much inconsistancy? I mean, how is it that some modified 335i BMWs barely ran as quick as my stock one? I mean, my car right now with the JB is significantly faster than did my "strong running" stock vehicle. With the advertised HP increases, the trap speeds should go up accordingly. Other than the "unusual" 111mph trap that Shiv achieved in his test car, looking at Dragtimes.com, how come no one else seems to be breaking out of the 108-109mph range? Besides Shivs run, on Drag Times, Maxboost was the only one to break 109MPH in the 1/4 mile (Using Drag Radials). With the projected HP increases, one would think that the Procede version 2 "should" definitely be turning 112mph+ terminal speeds. I can't wait to see the test results. Also, on that 111mph run that Shiv made, was that on 91 octane also? I'm sure it was posted somewhere. If I remember correctly, that was with a catback exhaust too? What would it have run without the exhaust? 109-110mph? It is disgusting that the stock Corvette is supposed to run 115mph in the 1/4 mile, LOL.
FYI: At German Invasion, I have the time slips showing my runs against a Turbo Tuner and Procede 335i. The difference in our 1/4 mile ets were only about .024-.171 seconds respectively. (And I basically had no cool down between my 21 runs!) Now I don't know what their best times were that day, maybe cars#104 (Turbo Tuner) and #127 (Procede) can chime in. But my best run that day was a 13.465, so I don't even know if their best runs were any quicker than the best runs in my stocker. Secondly, their MPH was only 1.024(TT)/2.484(Procede) faster than my bone stock 335i. Same day, same track. So I'm just trying to be objective here, but that sounds more like maybe a 12-30HP advantage over stock. So I don't see how people are figuring the Procede makes over 20-28 more horsepower over the JuiceBox, Ttuner, when the MPH on this day shows it is barely making 28hp over stock, based on terminal speeds. (Maybe the car was having technical issues?) The increased Dyno HP numbers just aren't showing up in "real world" conditions. Besides my tests, various magazines have tested stock 335i BMWs running at 106mph. How can a modified one only run 2-3mph faster with 45HP+ more? I am just playing the devils advocate here, as I am hoping the Procede Stg 2 delivers as promised, and the improved numbers show up on the road more than the dyno. I guess I will have to make it to the track soon to validate some of this info. Last edited by hotrod182; 09-03-2007 at 12:47 PM.. |

Yeah it sounds like Shiv hates the competition, but for what it's worth, it's a way better deal. The longevity issues I really doubt will factor in considering the small bump in boost and from the number of helpful people who have chimed in explaining how small the ramifications would be of running such a device. Let's say that the Procede does make more power, even twice as much, it's still A LOT more expensive. For the average driver who wants more power, without the risk of CELs, the Juice Box appears to be the answer.
There is already a confirmed pass at 12.9 something with a JuiceBox. At some point you have to ask yourself, is the $1000 more worth it to you for the small fraction in increased performance at very high speed? To me, and I'm soon guessing many others, it doesn't. The extra $1000 could be used for other upgrades like suspension or an LSD that appear to be more important to a car like the 335i. If you're a hardcore drag racer or a power fiend, get the Procede. Otherwise do yourself a favor and save the money by buying the JuiceBox. |

I tested again this morning. I was pretty excited, because my first run was a 12.884. Launched with no wheel-spin at all. I can almost feel the car trying to torque to one side of the road, which I never felt when it was stock. In all my runs, if I spun at all, it put me at low 13's in the 1/4mile. The ambient temp was about the same, but the humidity was a little lower, barometric pressure a tiny bit higher, and this time I tested with only a 1/4 tank of fuel.
But then the fly in the ointment. I noticed on my first two runs I was only trapping at 105-106mph range (like a stock car!). How in the world am I getting into the 12's and only trapping like I did stock? Then I made a run at 109+ mph. What in the world was going on? I reset the power to the GTech, and restarted it just in case. The MPH was still all over the place. Didn't make sense at all. I was thinking the following scenarios: A. My trans torque converter was starting to slip, killing my top end (Like my experiences with my Grand National lock-up converter trans). B. I was getting some serious top end knock retard. Which I figured was unusual considering the JB offers considerable mixture enrichment. C. My GTech finally went haywire after all these consistant test results. (I had previously made over 100 runs on it with no problems whatsoever) D. My HPF is finally giving up. I have been getting some long cranking episodes several times a week. (For about the last 4 months) Well, I think I might have it figured out. Lately I have been driving till the L.E.D flashes on the GTECH and then I immediately hit the brakes. I wish the thing would beep! But upon closer look at the graph, you can see that I am hitting the brakes before the end of the 1/4 mile! You can see on the acceleration G force graph, that only the run such as my 109+ mph run shows the acceleration right up to the 13 second line. I well verify this later on by not letting off the throttle so soon. This shows how invaluable it is to have graphing tools for your cars performance. In this case, my ETs were fairly consistant, but my MPH all over the place. My first run (the black line) was on target for the best MPH of all the runs, had I not hit the brakes before the 1/4 mile. I will verify my suspicions at a later date. But for now, I can't say how impressed I am with the performance results I have been getting. And this is on 91 Octane! If I can confirm I was letting off the throttle too soon in some of my runs, I am confident at the track this car will run in the 12's, on street tires! (Under the same ambient conditions). Hoping I can get some more 109mph runs, can't tell you how impressed with this JB Stg 2 so far! P.S. These JB performances are the real thing. There was a new post on drag times http://www.dragtimes.com/BMW--335i-Drag-Racing.html, of a stg 1 Juice Box equipped 335i (335FLL #17) and a Procede 335i (335Montego #16). Well they ran about the same time, but the Juicebox 335i was .45mph faster. But the main difference is the JB guy probably spent $99 instead of $1000+. I know, different conditions, etc, etc. But since the stg 1 results were just posted from Florida, I don't think the conditions were that ideal down there either.

Also keep in mind, it was pretty apparent you have a strong running stock car. As you were running .2-.3 and 1-2 mph faster than other stock 335i's up there at LACR. Also keep in mind, the faster a car's ET the slower it's trap speed. With the JBS you installed and were running at sea level, your best was a 13.05 ish at 108 something. On PROcede v1.2 I ran a 13.03 @ 107.6 That was at 635 feet in elevation. And my time corrected to sea level is a 12.9 @ 108.1 mph. It was also my FIRST time at that track and FIRST time drag racing the 335i. You have dragged raced the 335i hundreds of times to get really no better time with the JB2! Each of my 3 runs got better. I'm confident with another run or two I'd of been at 12.9's up there, and at sea level and a bit cooler weather would of been 12.7's on v1.2...not too mention if I'd have dialed in the car's ability with a hundred or more runs like you've made on your car. But again, you seem to have a particularly strong running car too. But in that regard, the JB2 seems to run close to what a v1.2 PROcede runs, and my sedan wasn't a "ringer" of a stock car, though made slightly above average power on Harman's dyno when compared to the other 6 sedans that dynoed their at the first Procede LA Dyno install. As for Shiv's 111 trap speed. So far he's the only one to have run at Sacramento, so the trap might be fast. And again, he had a pretty bad ET for the power his car had and therefore he had a few extra tenths to gain speed. Like dynos, you can't compare times from months ago at a different local, with different tunes at different test conditions to what you just got with the JB2. I'm sure if 20 people did 20 comparison dynos like Mr. 5 did, you'd see the PROcede's numbers would be the highest each time. Therefore, I'm sure if you had 20 people test 1/4 mile times on the same day at the same location with the PROcede and others, you'd see the PROcede cars times would also be the fastest. The PROcede cars may only be trapping 1 mph faster than what you just got, but they are doing it in .2-.3 seconds less time as well. That's indicative of having about 20-25 hp more. Exactly what Mr.5's dyno test showed. For the money the JB2 gives good results. It's the quality of the "tune" and the quality of the person selling it that would keep me away from putting it on my car. Sure he was great to you now that he wants your money. But the truth of his personality showed for months when he didn't want yours and other peoples money before trying to sell a homemade "tuner" box for your $45k+ car. |

Also keep in mind Hotrod, the times on Dragtimes were done at NHRA drag strips and timed with timing lights.
Even though your GTech has showed in the past to be pretty darn accurate, the consistency is unknown and still not a drag strip timing light. Furthermore, traction is often much better on the street than at most drag strips, so until you directly compare the different tunes on the same road, same day, or take your car with the JB2 to a NHRA dragstrip, it's not really fair or relevant to compare your questionable accuracy times on a road surface using the GTech to times done at sanctioned NHRA dragstrips done with timing lights and more often than not worse traction. |

BTW, Hotrod, great info and post.
I wish the VBox GPS had the software of that GTech. Then we'd get the best of both worlds....exceptional accuracy of the GPS based VBox and the awesome data logging of the GTech. There is no doubt you got more power with the JB2. Looks like the power gains are very similiar maybe a tick more than the SSTT. Again, great bang for the buck. But so is buying many products made in China...especially the knock-offs. But we've known the quality of many of those products for years too. The old saying, "you get what you pay for" very well may apply here. You may get more hp per dollar than the others, especially PROcede, but there are a lot of other factors to consider. Take care and can't wait to meet up with you again at a drag strip this fall. |

Although his ETs and trap speeds look decent, I noticed that his 60ft. times aren't all that great...all above 2.0 sec. 60ft. One thing we'll see over the next few months are PROcede v2.0 335i's running against JB 2.0 335i's at the track, which may help to confirm (or not) some of these street runs. I will admit that when I tested my $99 Beltronics Vector FX1 at track, its accuracy was fairly close (and it actually recorded a tad slower than the official track numbers).
btw -- this guy just posted up at DragTimes.com; he runs the JB 335i, but v1.0, not 2.0, so I don't know if it's comparing apples to oranges. Anyway, his ET was just a 1/10th sec. faster than a stock 335i, but his trap speed was a few mph better; I know this since I ran my PROcede 335i side-by-side with a buddy of mine in his stock 335i at the same Moroso track this past June (I ran 13.097sec. @ 106.67mph w/ a 1.9777sec. 60ft. and he ran 13.6-13.8 sec. @ 102.xxmph)... http://www.dragtimes.com/BMW-335i-Timeslip-13065.html

Unfortunately I didn't take my 335i to Famosa that same day. I took my 2006 M3 there. The car totally stock with SMG ran a 13.556 @ 104.14 (N/A and Uncorrected). If you remember that day wasn't particularly cool. Famosa isn't at sea level, but on that day, (same day you were running) I really only lost about 2-2.5 mph in what I would typically run in my M3 at sea level. And I backed those up with my Gtech readings. (By the way, this is close to the 13.532@104.68mph run made by a LS2 GTO posted on Drag Times from that same day). But the point is, I know the higher the elevation, the more pronounced the advantage is for the FI car. My 335i at LACR was over a 1/2 second quicker than my M3 at LACR. (13.465 vs 14.01). So the point is, even at Famosa, I believe my 335i would have run low 13's stock, given that LACR has a much worse DA reading in general. So with the JB2 it should be extremely low 13's to high 12's just based on the differences I am getting compared to stock now.
Driver 72, I appreciate your observations, as you seem to pretty methodical too. This is why I make an effort to use the data I have from both the strip and the GTech to form my OPINIONs. But I think I have a pretty good feel for what is reality and what is unsubstantiated hype. But If I can get some more runs down here, repeatedly at 109mph+, I know (given all the factors so far), I will get some pretty impressive runs at the track. I am honestly ecstatic with the real world improvements I am getting right now. What is more impressive is these are on my worn Exclaims, on 91 octane. And as you know, all my best drag strip times were done on stock RFTs. I am mostly interested in the terminal speed right now, rather than all out power braking, and launching with DRs to get that trophy ET. Yes, even though my Gtech isn't that old, I am thinking about getting the VBox for verifiable consistancy. But the graphing on the GTech IS very useful. It is a great tuning tool. Great for analyzing your launches, etc, etc. And I personally have always liked going with the underdog, even though it might not be the easiest or best route to take. I mean, I know many people may not like Terry, or the JuiceBox for that matter, but I will need further data to see if the Procede performs that much better than the JB2 as it has been hyped to on the dynos, etc. Hey, if my JB2 makes only 5 more horsepower then stock on the dyno, but somehow manages to run 108-109mph in the qtr, I'm still happy!. Now the Procede V2.0, will be a whole different story. Lets see if it lives up to its hype. According to Shiv's test results, if he ran 111mph at Sacramento with the old Procede, he should be running around 115mph with the V2.0. (with its 40hp+ or so). What if people can only replicate 111mph in real world tests? I would be happy with 111mph in my car (about the same as the E92 M3), but disappointed with what was expected/promised with the hp increases. To put things into perspective. If the Procede is supposed to put out 28hp more than my JB2, then when we go to the track, I fully expect the current procede to trap 2mph faster on an otherwise stock 335i, compared to my JB2 equipped 335i. If it doesn't, I just don't appreciate those huge dyno number advantages as much as some people do. On the other hand, if you are down here in So Cal with a Procede on an otherwise stock 335i, PM me, we can hook up my meter, and test both cars at the same time. And compare the graphs. That would be some excellent information that others would find interesting. In that case, I would expect the Procede to trap at 111mph. Maybe it will, and that would validate Shivs run at Sacramento. We definitely all have to go up to Famosa again when it cools down. That was lots of fun. Hopefully this time I will get up early enough to join the Caravan. Do you know anything about Fontana, or Pomona? Are they good drag strips? I hear Pomona is only 1/8 mile?

Seems to me like the differences in terms of 1/4 mile times are really negligible, however the price is not (especially if you look at it on a dollar per milisecond improvement). Having said that, the only question I would have is what is "safer" in terms of the engine not blowing up?
To be honest, JBS seems very cheap, which makes me skeptical of its durability and quality (hope this is not the case). |

I think the major point of these tests needs to be the proximity of the times of the two tuners and their relevant price point, not just the ability of one to outperform the other. I would totally understand the comparison if they were both priced similarly. However, as it stands, one is priced at ~$350, the other ~$1500. |

But back to the point, there isn't any evidence to support that you are less likely to blow up your engine with a $1300 Procede than with a $349 Juicebox. If you know specifically why I might be wrong in this assumption, please post the technical details so we can all learn why. Like I have said, I have been receptive to all the information out there and tried to make an educated opinion from all of my observations so far. Last edited by hotrod182; 09-03-2007 at 01:47 PM.. |

Again, there is a difference between road grip and dragstrip grip. When I got my 13.0 flat at Famoso that day, I got a bit of wheel spin and didn't launch it as hard as I could on the street. Had I been able to launch it as hard as I did on the street, 12.8's would of been cake. Quote:

Terry or not, I'd still not put a homemade "tuner" box on my $48K car from an inexperienced tuner. Even if the JB2 did produce the exact same power as the PROcede v1.2 I wouldn't be the guinea pig for a first timer. The fact that Terry's attitude here for months and months, especially bashing Shiv after Shiv was the one who gave Terry all software workings of his earlier PROcedes, and then was stabbed in the back by Terry when he publicly posted them, would keep me from buying Terry's product...even if it made as much power as the v2.0 PROcede and cost $350. I don't support people like that...underdog or not. Without Shiv and the early Xede's and then PROcede's we wouldn't have the options we have today. Without Shiv, 99% chance Terry would not be in business with is JB2. Terry for some reason had an early hatred for Shiv, but ironically, that and Shiv graciously giving Terry his software info, is what got Terry all amped up to make his own version. Those are the two (inexperienced tuner and Terry's past actions and personality and hatred towards Shiv) reasons I wouldn't buy the JB2. And just one of those two would of been enough for me not to support it either. Quote:
Without it, he probably would of only trapped at 109-110. And, the faster you go the more power you need to knock off .1 and add 1 mph. Meaning, the "addage" 10 rwhp = .1 second and about 1 mph is easy when you are only pushing the car through the air at 90-100 mph. But at 110+ mph it takes more power to push the car through the air and therefore add 1 mph to your trap speed. So if v2.0's final tune does add 30-40 hp, it may only knock .2-.3 and add 2 mph to the time. Then keep in mind, the faster your ET the less time you have to accelerate, so often your traps drop a bit. Shiv may go back and get a 12.8 @ 111 mph with v2.0 but that would still clearly show a big power increase. To get 111 mph trap in .4 seconds less time is a big improvement. Quote:
It will be fun to go up to Famoso again in a month or so when it's cooler. By then we'll have all kinds of 335i's up there (stock, TT, JB2, PROcede v1.47 and hopefully PROcede v2.0 too). Unfortunately, driver skill plays a BIG part in dragstrip results. It's rolling runs that eliminate most all driver skill (especially in autos) and showcases the car's power. We will have to do a couple of them too. Glad you are happy with what you have. You really should try a PROcede though to compare. Maybe we can meet up soon. |
