6. Fill the 1 gallon space in the 3 gallon jug by pouring out of the 5 gallon jug.

Voila - assuming you didn't spill any, you have exactly 4 gallons in the 5 gallon jug.

(I love these brain teasers!)

Or...

1. fill 3 gal jug and pour it into the 5
2. fill 3 gal and pour into the 5 till its full. leaving 1 in the 3 gal
3. empty the 5
4. pour one gal from 3 into 5.
5. fill 3 gal again and pour all into 5. = 4 gal

I like them too. :-)

On topic - these numbers are great! I have been really hesitant to due any sort of tune (cost and warranty issues) but the price per hp for this is too good to pass up.

So going from 91 octane to 94 octane on the JB3 map 6 only gained 10hp??? I was told it should be "a whole new tune"?

and i know this has been asked a zillion times, but how can i find my progman version? i know the dealer can do it, but wont. can i do it with a Bavarian Technic?

Pre release sale is on now Check my sig and the site

The numbers from 93 octane on max and 93 octane on default are so similiar its almost seems like its not needed to turn it up. Although Max setting is 5psi, i think 3.5-4psi should be enough to be scary enough

[Universal_Magnetic]

on 91 oct, whats the highest level you can run the JB+ on?

I think the settings are more dependent on SW version more than octane....

Here's the deal guys.

The JB3 Map 6 on 93-94 Octane runs we did were the very LAST runs. We did nearly 25 runs in 1 hour 15 minutes. And the numbers you see for JB3 1.2 Map 6 on 93-94 Octane were done with only about 3 minutes cool down after doing 2 back to back runs.

I would expect if we had more time to let the car cool a bit further it would of been 4-5 rwhp and rwtq more at least.

All other tests, dynos I and Terry have ever done have always yielded about +10 rwhp and +10-12 rwtq with 93 Octane over 91 Octane.
Even on a STOCK car a dyno test I did 93 Octane got 4 rwhp more than 91.


As for how "close" the JB+ is to the JB3.

Well, it's a bit misleading. First off, not too many people can or will run the JB+ fully turned up even on 93-94 Octane states as it throws the warranty code.
And even IF they do, they'll be a solid 12-14 rwhp less than the JB3 and that's just at the peak.
Above 5000 rpms and especially above 6000 rpms where it counts when racing the JB3 makes like 25 rwhp more.


Also let me let you guys in on a little secret too.

After we dynoed my car on JB3 1.2 Map 6 on 91 Octane we threw in a JB3 1.3 chip on Map 4
and on Map 4 the 1.3 made almost the exact same power as 1.2 did on Map 6 AND the curve was smoother on the 1.3

The 1.3 on Map 4 made about 4-5 rwhp more than 1.2 did on Map 4 with 91 Octane.
Which was about 15 rwhp peak more than JB+ turned up fully on 91 Octane and 27 rwhp peak more than JB+ on default setting on 91 Octane.


I was certainly impressed with the JB+
In the default setting it makes about 7-10 rwhp more than the SSTT does.
But in terms of power it's closer to the JB2 than the JB3 when on the same octane and looking at the entire curve, not just the peak numbers which matter for only about 25 rpms out of 7000 rpms.

The JB+ is a serious option for those strapped with cash.
But to me it makes no sense to buy the $279-$329 JB+ if you have a post 29.2 car and if you are going to run it more than the default setting then have to spend another couple hundred for the BT tool to clear the codes.
When for maybe $100 more than those two things will cost you, you could get the JB3 and with 1.3 on Map 6 have a car that has 10-12 rwhp PEAK more and a good 25 rwhp more at 6000-7000 rpms and not have to worry about clearing codes.


More than likely I will set up a "test" of some rolling runs with the JB+ and the JB3 to give you guys an idea of the difference on the road. I would suspect from 40-120 mph the JB3 will pull 3-4 CL's when on 91 Octane and JB+ on default settings and 2-3 CL's when on 91 Octane and JB+ on max settings.

[Driver72]

Oh and somebody asked the details on the car for the dynos:

pre 29.2 stock 335i
(only other mods are 19" wheels with 265 rear rubber).
6AT
9900 miles on car
Stock air filter with about 500 miles on it, so it was clean.

[thisguyhere]

Thanks for the good info Driver72

[freshwhite335]

hmm cant wait to get my car back form the dealer tomorrow to see what software version i have, if its pre 29.2 ill be turnin that bitch up all the way. its sitting on my desk right now teasing me.

[Riss Racing]

Very nice!

[jcarlucci1]

Alot of good points here..I went from a jb3 to a jb+ (turned all the way up). JB+ is great and has lots of torque..but above 5500 rpm's, it is no comparison with a jb3, even on maps 3/4

[darkphantom]

oh damn @ jb+!

[E92murdered]

im not sure if it has been proven that the jb+ if post 29.2, if the boost is set above the default there will be codes?

[Scimitar335i]

RIP $599 MSRP SSTT... those who sold their SSTT before JB+ came out for 300 bucks were lucky.. now they're lucky to sell it for 200 bucks.. competition is a great thing!!

[Rotary Rasp]

Just a quick question that hopefully isn't too off topic.

The car dynoed was a AT... I have a MT.

Do the stock MT's put down the same power as the AT?

[shiggy]

or:
fill 3 gal....pour into 5er
fill 3 gal...pour into 5er...leaving one gal....pour into gas tank.
fill 3 gal...pour into gas tank.....4 gallons......volla!

Im running the JB+ on about 3/4 setting on a post 29.2. As a matter of fact I am running on the very lastest update.

I only started this yesterday but I looked last night and no codes. I am going check again in a few days.

[DELTA BMW]

Rocket keep me posted I may turn mine up. I guess it's time for a BV tool.

If you want to turn up the juice on the JB+ on a post-29.2 car then its a good idea to have a scan tool or at the very least be friends with someone who has one LOL

mike how hard is teh BT tool to use? im a noob and i bought the jb+ but i want to make sure it goes totally undetected

No problem.

Once the JB3 1.3 is finalized Terry and I may go to the dyno again and see how it goes in 91, then 93 then maybe 98 on the various maps.

Then maybe throw the JB+ on with the 98 Octane and see what it does on a moderate race gas mix on max setting too.

The JB+ will surely force the SSTT to lower it's price. But with the JB+'s ability to adjust boost from 1 psi to 5 psi above stock it will make it hard for the SSTT to compete anyway.

I don't think Terry recommends running the JB+ on full boost on 91 Octane however.
In most tests, including with the JB+ 1 psi boost increase almost ALWAYS makes for a 10-12 rwhp gain on 91 Octane.
It was the case between the lower settings on the JB+ and the default setting.

However when going from the default to max, the increase is only 8 rwhp even though the difference between default and max is closer to 1.5 psi.
Max power on 91 Octane resulted in ~321 rwhp and ~340 rwtq.
I think .5 psi over default would probably result in nearly the same power or about ~318 rwhp and ~335 rwtq.

Without the superior control and tuning of the JB3, pushing more than 12 psi on the JB+ (about 70-75%) it seems the stock ECU pulls some timing or something.

On 93-94 Octane it appears the JB+ can be turned all the way up without knocking or timing being pulled as the power jumps up nearly 20 rwhp more than on default setting, again, compared to the only 8 rwhp gain between default and max setting on 91 Octane.
This would probably be the reason we never saw the SSTT v2 which would probably allowed more boost and power, but at the risk of warranty code triggering and on 91 Octane not enough of a power gain to justify the additional 1-1.5 psi boost.

Those who want a SSTT type device that makes similiar (or more power when turned up) the JB+ is the perfect tune.

but again when it comes to acceleration compared to the JB3 expect trap speeds to be 3-3.5 mph slower on same octane.

Meaning on 91 Octane:
JB+ default setting would trap in the 108 mph range
JB+ 75% setting would trap in the 110 range
JB+ max setting would trap in the 110.5 mph range.

Add 1.5-2 mph for 93 Octane.
Again closer to PROcede v1 and JB2 to JB2H times than JB3 or PROcede v3 times.

Warren has got 110.5 mph on JB+ at 75-80% setting on the VBox, which would probably be 109.5 or so at a drag strip that measures time as an average over the last 66 feet of the run.
He may do some official runs on a strip soon.
Great numbers for spending around $300 or so dollars for a tune.
