ADM FPCM throwing codes
Started getting these codes about a month ago. Car has had the FPCM in for probably 2-3 years now with no issues. I can drive the car, clear the codes and they will stay gone until the next morning when I start the car up again, if I try to clear them prior to driving 20-30 min the command is rejected. Anyone ever delt with this and know of a fix?
Codes P069E fuel pump control module request mil illumination and code P2534 ignition switch run / start circuit low.

Yup, i went through this. If I clear the code while the car is running, it shuts off. Car restarts shitty, throws code, repeat. The code is thrown when the commanded fuel pressure and the actual fuel pressure are too far apart. My logs show short dips and spikes of fuel pressure. I have a stock SS fpcm that has been flashed with the ZL1 fpcm settings. (In case you didnt know, hptuners 3.6 now supports fpcm access, and we can flash them ourselves). Sorry ADM and JRE.
I also experienced a blown MAF fuse when this occured. Replaced the maf fuse, tuned out the p069e, and all has been good since.

Awesome thanks. Hopefully it will be fine when I take it to be tuned on the 14th

Do u run a bap? I think the combination of the fpcm commanding 58psi(zl1) instead of 48psi(SS) and the sudden increase in voltage from the bap might have something to do with it. Either way, i tuned it out, data logged and my afr and fuel pressure are rock solid.

I had a bap hooked up, it went bad so I have it disconnected until I can buy another. This all happened about the same time come to think of it
