Timing 33 degrees in cylinder one and 7 degrees in all other cylinders
What the hell is going on here?? I dont even know where to start to what could be causing this.
Running the BMS single turbo pump flash with only changes being the single bank o2 enabled and ADV option enabled in MHD.
Anyone??

Its part throttle, so i wouldn't be overly concerned. Could be DME doing individual cylinder calibration or some excessive EGR causing it.

Have you turned off the JB4 O2 calibration for pressure once ADV is installed? I think it was some sort of bit enabled value I read somewhere on N54tech.
FUD bit6 - Disable o2 pressure correction.

Thanks for the responses guys. I have disabled the bit long ago once i installed the ADVs. I hope its something as simple as this thats getting overlooked but I havnt changed anything on the JB in a while. This all started once I went from the BMS port injection TS single turbo map to this one but nothing on the JB side.
In terms of the DME trying to individually calibrate cylinders, why would all 5 be the same and only 1 be out of the roof?? Wouldnt EGR effect all cylinders similarly?2010 AW/BLK 135i VM 6465 Single Turbo w/ OCDworks Modified T51r Housing, JB4 + MHD, VRSF CP & Tial, Big Tom, Fuel-It PI + Stage 3 + Return + Ethanol Sensor, BMW PE, MFactory LSD, Spec 3+ & MFactory SMFW, RB External PCV, ADV sensors, and many more....

The timing 2-6 only reads up to 25 degrees in that firmware then overflows the byte. So it's just a false reading. Instead of 33 you see 33 - 25.

AHH That explains so much! Thank you so much! I was worried about it and was scared of driving the car hard if the individual cylinders were getting a substantial amount of timing more than others and this cleared it right up! Originally Posted by Terry@BMS
