I have the Gen 7 piggy backing the LT1 pcm with the fast track wiring harness, Everything is working great, NOW my Eng light is on witch would be understandable....can i turn these codes off with edit and still have the pcm work ?


I also have a dual sync dizzy installed with the msd box so i no longer have the opti can this be turned off

thanks.

or what can be turned off and what should i not turn off

 

What are you still using the stock PCM for? I use it for the fuel pump control, speedo and idle air control. I have at least 10 codes for the missing injectors, MAF, KS, AIR, EGR, ICM, EVAP, AC, auto tranny, etc. Codes don't hurt the things I'm trying to control, so I just snipped the wire for the SES light. I can't see any purpose in any additional programming on a PCM this isn't being used for much at all.

I did parallel sensors for the pure resistance loads to both the PCM and the ECU... e.g. IAT, CLT, etc.... so that I can monitor those on my ScanMaster.

 

LOL i have the same and a few more codes, just the cooling fan's are on now because of the codes, i would like to tune them off so that my fan's are not on all the time ..other then that, i don't care...i could wire the fan's up diff .....

what do you think
