Hey guys,

I saw this before and after diesel dyno posted on bimmerfest and thought you guys might be interested in it. The testing was done with the JBD at the default setting on an AWD dynojet. Pretty solid gains for a 45 second install mod.

Can you explain why the car goes into limp mode when you floor the accelerator with JBD at 85%+ using the new chip? If you turn off the car and start it again, limp mode goes away but I'm sure a code is stored. Can JBD only be run at 65% or stock setting to avoid this and SES/CEL lights?

Also, the 45 seconds may be for the X5, but those hex bolts on the 3er will take a bit longer... BMW's fault.

All cars will trigger a tuner detection code at some point between 70-100%. It setting varies by car based on the DME version and other car to car variance items. So you can leave the default setting and enjoy a trouble free install or if you feel like chasing every last horsepower up the dial as high as your particular vehicle will allow. Just be sure to get the CAN Tool ($50 extra) to clear the detection code before going in for service.

335d runs 250/403 stock? That's pretty damn high

What is the factory setting at (50 or 65) and can you show me a picture of where the arrow would be at 69% to avoid tuner codes?

[EYE4SPEED]

Can anyone post a pic of where the arrow would be at just under 70%? The codes thrown may be "tuner codes", but they put the car into limp mode. Why not just make the unit with one setting at 69.99%?

Valid point. It's my understanding, that not everyone experiences limp mode or SES lights at 90% to 100%, it's car dependent. My car doesn't go into limp mode/throw SES lights anymore now that I have it set at 85%, so a 69% limitation would suck in my case.

Why limit the tuning to the lowest common denominator. Many cars can and do run 100% without the tuner code. Other cars can only run 70%. Those who want more power are happy to raise it and see if their car throws the tuner code. When you restart the car the code turns off and the CAN Tool can delete any hidden remnants. It's not a big deal to those who are looking for maximum power for their cars. If the thought of a check engine light keeps you up late at night please run on the default setting.
