N55 JB4 jerky when startup
I recently installed my burger tuning JB4 along with a injen CAI and a RaceWerks charge pipe. When I have the Jb4 turned on the car is very jerky when idling, especially pulling out of the drive way. When I turn off the JB4 it runs perfectly fine. I haven't had any other problem with the JB4 and it definetely increase the performance. Is there a way to stop the jerkiness by putting on different parts or something?

Weird. Mine happens more often when cold and I'd get a drivetrain malfunction full engine power not available warning.

If you are able to get a CEL out of it you're way ahead of the game. Read the code and then find someone who knows what the code means to help you solve it. If you have a BMS product on the car you can post the code and details in their support forum for professional help. If you are not able to get a CEL then its much more difficult to determine what is wrong. A datalog is normally a good first step though. Mike |

Same issue here, engine just got low rpm when I cold start it, and then it jut goes off. It doesn't happen everyday on my car though. ( I got JB4, ER down-pipe, Akra exhaust, and AFE intake)

I would start by datalogging if possible
If not remove the intake

It annoys me and I don't even have the big problems you have. I'm resolving it via ENZO flash tune . I'm not screwing with this anymore. Good luck.

122108 Blow-off valve: Jammed closed 108A10 charge air temperature sensor, electrical: signal not plausible 120408 charging pressure control, deactivation: pressure build up blocked 180001 catalytic converter: efficiency below limit value These codes came up during the CEL. This was one week ago. I managed to track down a GFB DV replacement assuming the BOV/DV is faulty. (The GFB DV replaces the diaphragm of the OE DV with a piston type internals). GFB DV installed today. Now I'm still getting the "drivetrain malfunction" warnings here and there, although they're not as frequent as before the DV replacement. Going to the workshop tomorrow again to scan for codes. :/ |

Let us know how the flash tune goes. I have access to cobb over here if all else fails with JB4.
