Thread: Does a P59 PCM have some sort of safety cutoff?

    Does a P59 PCM have some sort of safety cutoff?

    Hey guys, did some searching but couldn't find it. So, I have a P59 computer 4.8 that I just threw a cam in. Everything else is totally stock. But now since I've put the cam in, the computer is killing the motor and the fuel pump signal after a minute or two of running. I haven't touched the tune yet so I think it's possibly some safety cutoff from the bigger cam triggering the knock sensors, but really not sure... Any help would be great! By the way, it's in a swapped vehicle so the VATS is disabled, and I've changed nothing in the tune or sensors or injectors or anything, so not sure where this new problem could be coming from, all I did was pull valve covers and front cover to change cam and this problem started! Thank you.

    Thanks guys, I actually figured it out and forgot to update, it was because the p0106 wasn't deactivated in the tune, and it was making it cut off for some odd reason
