I get the DCT light flashing like crazy in second in my auto e90 with just a jb+ and dci.

Errrr, see my post below, it seems at least one person has come close to his times. Maybe you should do a little more research before you blurt out things that aren't true.

12.5@115 w/ a 2.1 60'

Something they said in that thread was that the gtech reads ~1mph lower than vbox, so basically it is a 116mph trap.

Seems to me like someone just replicated his traps right there.

Yea...its 499+shipping...just ordered mine and had it overnighted so i can play....

I just saw a JB3 135 with DCI on 96-97 octane only trapping 110 at the drags this past week...Why the big difference in a car that weighs a couple hundreds lbs lighter? 5 mph is a huge difference, factor in the weight and it's more like a 6-7 mph handicap in a car that has DCI. Oh and you did it on 91 octane. It doesn't add up. If I could get 115 mph traps pump gas, I'd be all over the JB3. I just don't see it as being a practical result.

Brianhn1, where in FL are you? I'd love to meet up at a dragstrip to do a comparo. I'm in Orlando, we have a dragstrip here, but I'd possibly be willing to go to PBIR, Bradenton, or Gainesville. I only have DCI, but if you don't I'll take mine off. We'll run the same octane too.

Hotrod, if you are really getting those mph on 91 octane, then I am jealous. I'd like to see it legitamized on a timeslip though.

It has everything to do with the conditions, and traction.

Go out with a negative DA and a decent 60' time and you will get good traps. It isn't as complicated as you guys make it seem.

115+ mph on 91 octane is as complicated as we make it seem. Just about everyone here (excluding a select few) will have a hard time achieving that on 105 octane. In over 250 passes at the drags, in both good and bad DA, I have not been able to achieve that. Granted I've never had a -2000 DA or better, but I'll bet Hotrod's DA wasn't that good on these particular runs.

GT man, I am happy to come meet and run with you. I have a couple guys that are willing to run with us (stock 335 and 135 manual with FMIC, DP, DCI) but we can meet at Speedworld for a few runs. I don't have DCI and am auto with DRs. I'm up in Jax so it will be a couple hours drive for me down. Unfortunately I'm heading out of town right now and won't be back till next Sunday.

For some day runs, maybe Gainesville would be another option at the end of this month I believe.

Im down for a meet in gville raceway just let me know when

[hotrod182]

Okay, so with everything else the same as the previous test with a 115.3 mph high, I put in some 100 octane fuel. Probably a 97 octane final mix. Mph didn't go up a huge amount, but I seemed to have gained about 2.5 mph, or 25 hp. I guess that seems pretty plausible. Traction wasn't that great, so no 12.0 or high 11's. But a 12.1 with a 2.0 60' time is pretty good. And the 117.8 mph trap is pretty much identical to what I got in Sacramento.

Well at least this shows the progression in performance through the steps. Same track, same night, etc, etc. Except for the 1st run where there probably was no adaptation, you can see my runs are very very consistant. Well hope this info helps out some of you.

Let's see some of your slips before you start with the attitude. 12.4 on RFTs can tell you a little of how I can drive.

Orlando Speed World is open Wed and Fri nights and first Sunday of every month (usually). I can pretty much go any day, just let me know. I have already got other inquiries to meet up from other JB3 cars. We should definitly set something up, it'll be nice to see some other BMWs there.

I haven't been to Gville yet, but I'll make the drive whenever.

I'll also bring some other sweet rides to the party (11.2s e55, 11.3s SC mustang, 11.4s c63).

Hotrod, what is the DA when you are performing these tests?

Sounds great. I'll count on you to organize some stuff since you're closer to Speed World but I will definitely let you know. Heck, I'd be interested on a private track day but I'll let you look into that.

G'ville doesn't have many Test and Tunes any time soon because of events (Gatornationals, etc.) but it is a decent track when it is not crowded.

Do you brake torque at all when launching your car at 2nd gear on Map# 5 with street tires?

Originally Posted by hotrod182

I have been doing some JB3 1.3 Beta map testing for the last couple of weeks. This weekend I downloaded one of the newer maps for some testing. Last night I made 6 runs, they were all above 115mph on the Vbox. For those of you that like low end torque, how about a 2nd gear start, and running a 4.2 sec 0-60 and a 1/4 mile time of 12.5 at 115.6mph! You can see how starting off in 1st gear requires so little throttle to spin the tires, I have to ease off and the trans short shifts from 1st-2nd gear at somewhere between 3800-4000 rpm. Being that these tests are on regular 19” General street tires, I found it better to just leave in 2nd gear.

Keep in mind my best run was on map #5 (lower torque map) launching in 2nd gear. I didn’t even try 2nd gear launch on map #6, but it may have been even better. But the point I was trying to make about the placebo effect of low end torque is that a person might think a car is so much faster, when it really has no better acceleration numbers. If it is just a matter of having to depress the throttle more for the same amount of power, I don’t really mind that. But again, if you want to impress your friends that drive that car thinking the thing takes off soon as you give it gas, then its your choice, and just a matter of switching maps.

Here is the video of the 2nd gear launch run:

FYI, this 12.5 at 115.6 mph can easily be a 11.95-12.00 second run with traction, as my 60’ time was only 2.1 (slightly damp road). Again, no aftermarket exhaust, downpipes, intake, etc. Just regular 91 octane, non race map, and poor traction. And another key piece of information, look at the very mild boost the car is running through the run. Barely averaging 13psi! 4.2 seconds 0-60 isn’t to shabby given the conditions. So a 12.00 flat run possible on this, and I am predicting 11.7x on my race map. N54 performance has come a long way!

+1 I love Map 5 on 1.22 as well. So I know it feels different from Map 5 on 1.22, but is 1.3 Map #6 faster? Any jerkyness?

Reference point:

Before testing 1.3 out, my favorite map was JB3 1.22 map 5. I liked it because of the relative linearity and absence of kick that map 4/6 has.

Preliminary butt feeling - WOT:

Drove out of my neighborhood on to the highway and floored it. Wow amazingly smooth and stock like feeling. Did I set the map switcher correctly? Checked the boost gauge and see a healthy 12-13 psi so I must have. After a few WOT runs, I coast to the side of the street and switch to map 6. Started it up and gunned it a few times and I fell in love. The improvement on the linearity of the power delivery is very noticeable.

Preliminary butt feeling - throttle jabbing:

During the quick jaunt around on the highway, I spent some time jabbing the throttle to approximately 30%, 50%, 70%, etc. and can say the response is significantly different. I did this in 2nd through 6th gear and was completely impressed with the difference. More on this later.

A better, more complete review will be warranted later but I am posting a preliminary review as sometimes a first impression is different than a long term evaluation.

****
Of course for some of you guys curious to see what a 20 to 80 mph 1st gear start run, with the following specifications on my car, are welcomed to be entertained:

JB3 1.3-7F Beta
Nitto 275/40R17 (50 miles with a few burnouts) DRs
Stock airbox, downpipes, exhaust, FMIC (hotrod's twin in sedan form)
2008 335i E90
65F
93 octane

I'll bet you folks in Georgia and Florida face much higher humidity than Hot rod in California. That certainly must have an effect.

Yes, slight brake torque in 2nd gear. Don't want to do it too much, because spinning tires in 2nd gear is even worse than doing it in 1st gear.

DAs are definitely good, that why I am a little disappointed I wasn't getting 119mph. Normally that would come though with more runs and adaptation. In other words, more often than not, I will go back a few nights later, same conditions and will trap higher.

That 12.5 could just as well be a 12.48, etc. 19" Exclaims hook up as bad or worse than RFTs. So I too could get 12.4's on RFTs. Maybe I will put them back on just to prove it, but really no need to. And remember, there are no warm up burnouts in any of these tests. That is an area I will benefit from when I go to the track by improving my 60' times.

The consistancy of the trap speeds is almost eerie in some cases. Shows you the JB3 is not that erratic in output at all. Feels very smooth to me in the runs.

[jpsimon]

I need to get this device, I'm curious about what I can do with my setup. My neck hurts while accelerating from a stop with my AWD. i don't lose traction that much at all

[335i/335d?]

What kind of max boost do you see on the tested maps??
