Hey guys I have a 2020 L86 and E92/ T87a setup in a 77 C10. I cannot get the ECM to send 12V to the fuel pump relay. So far I've disabled VATs and disabled Starter Diag. Is there anything else that needs to be changed in the tune to get it to vibe with a fuel system that doesn't use the FPCM? I know countless guys are using a typical TI Automotive/ AEM etc intank pump @ 58-70psi but I don't know what they are changing in the tune.

2020 L87 E92 + VATS disabled, starter diag off, and DOD off.hpt
