"As far as DTCs are concerned, the big one to disable is P2635. This is considered a nuisance code, though there is a common misconception about what triggers it. It is not based on actual pressure vs expected pressure but rather actual pump duty cycle vs expected pump duty cycle. With an aux pump, the FSCM has no idea that some extra source of fuel supply exists, so this code can trigger. We recommend simply setting it to No Error Reported. "
I was reading this on the DSX page. Would adjusting the Duty cycle table by the fuel pump trim amount resolve the p2635 code? I tuned a truck and they later installed a dw400 as a replacement to the stock pump (not auxillary)and it popped the code. is there anything else that would need to be done? its just a cammed gen iv 4.8 silverado.
