p.s. the JB3 doesnt work during idle or before 50% idle, so highway you should be seeing close to 30mpg if driving normal.

my SSTT gets 32MPG on the highway on a 100 mile trip i just took.

I know how to use the OBC.
Before, I would get aprox 29-31 mpg if I stayed at around 10 in/hg vacuum.
Now, I get 25-26 when my boost guage says the same thing.
We are talking about when the OBC displays the instantaneous mpg.

dyno any Jb3 anyone ??

From the various comments/reviews of the JB3, it sounds like the power delivery would be great for the track nuts amongst us.
I like the sound of smooth power and throttle based boost.

I have the JB3 on my stock AT 535i w/ Sprintbooster. All these lack of low end torque that everyone is complaining about is NON-EXISTENT if you have the Sprintbooster. The power delivery is very linear and smooth at partial or WOT. I highly recommend it for all Automatic Transmission cars!

DOes the sprintbooster install at the tmap sensor where the SSTT is installed? Same place?

I would be frightened to use SB with pre 1.1, too much TQ down low imo!

so u went from stock and added sprintbooster and you feel a pronounced difference in butt dyno??

thanks

btw, how complicated was the install, and how long did it take?
lastly what did it cost (the link provided is not currently working).

JB3...so far so g00D.

morphia · 10-14-2008, 04:36 AM

Just install my JB3 last night. After 30 miles driving, as others said here, the low-end tq has not much noticeable difference compared to stock.(maybe need more milage for adaption). So I use my BMW performance steering wheel to test it : (the steering wheel is not calibrated, but it still shows the difference)

before :
0-100km/h : 5.65sec
0-1/4 mile : 13.78sec @166km/h

after :
0-100km/h : 5.16sec
0-1/4 mile : 13.28 sec @174km/h

I think I have to be more sensitive to feel the difference when driving.

BES335xi · 10-14-2008, 05:58 AM

^Morphia, which JB3 you got the 1.0 or the 1.1/v ? Cause they said the new chip that just came out improves the low-end trq..

Mine is '08/Mar production 335i(european model) with v30.2+JB3 1.1V.
I also have AA I/C, AA exhaust, VK OC and K&N drop in filter.
I think the testing data from steering wheel tells everything.
It do shorten the acceleration time especially in higher rpm range.
(I use DS mode and then full throttle till the end of testing)

before :
0-100km/h 5'65 sec
0-160km/h 12'92 sec

after :
0-100km/h 5'16 sec
0-160km/h 11'38 sec

the diff of 0-100km/h is 0.49 sec while 0-160km/h is 1.54 sec

morphia · 10-14-2008, 01:13 PM

After another 50 miles adoption with aggressive driving, I can feel the power become stronger and smoother now, low-end tq is better as well.
Nice product!! I think JB3 is the way to go especially for those who live abroad. CEL-free and longevity are the key for me to choose a tuner.
