I have a larger black and smaller black wire in the box. I beleive the rpm is the solid smaller black wire. Will look at pin 9 on obd. Tmap signal wire is solid yellow and I have located that in the DME aswell. Worried this might be for another connector

Back at this again. Car ran really well. Wedge acknowledged me to switch to e85 and take a log. He asked if the PI is firing. Going to check the voltage on the signal wire and find out what itís doing with a computer hooked up to the controller. One thing that baffles me is that during the log you see the rail psi drop to 2100, stfts maxed, and then I change gears and boom it held steady. Will report back.

Tmap is connected to solid yellow wire on tmap. I have voltage 1.2v. Rpm sits at 6700 at idle according to the r4 controller. I may have incorrect options selected but I donít believe so. Anybody have this issue, it seems so easy so I donít know whatís going on.

2011 335i, Pure 2, PI. I had an accident a while back. Putting things back together. The PI puts out fuel to the max. Wiring visually is ok. Any ideas appreciated.

Check your muffler bearings.

Actually, when I tried to remove the JB4 while the meth pump was still connected, it turned on full and couldn't turn it off. I'd suggest you double check you meth pump relay wiring.

Running flash tune, 50% e85, no meth. Per Steve Jenkins it is most likely an issue on the RPM wire. Will report back.

I may change out the muffler bearings proactively soon as the car has 70 k miles.

So it turned out that the program likely was corrupted when I had my accident. Reflashed, all bueno. Likely happened due to a power surge when the air bags deployed.

According to my records when I last had an alignment the muffler bearings were changed out under a BMW recall.

Hey, I've recently installed the phoenix racing intake with PI, BMS PI controller hooked up to JB4 with ethanol sensor. I've re-checked my work of hooking all the wires up to the right place, changed JB4 settings to the suggested in various threads - Fuelen does register, so thats good. But, I am not getting ethanol content readings on Duty Cycle after setting FUA to 58, and moving the ethanol sensor pin to port 3 on the db25 plug. I noticed that E85 signal does read as climbing along with Fuelen. Am I misunderstanding what should be displayed in which?

I'll upload a pic of the db25 in the JB4 to double check that was done correctly, and the other thing I was doubting is whether this black-grey-ish wire was the RPM wire shortly.

Attached is the latest logs while trying to see if anything is functioning as intended. In map 4 and 1, using e40.

Any thoughts on what I could have missed would be greatly appreciated.
