If the key isn't in the run position disconnecting the battery won't get the PCM to reset what it has "learned". You can put the key in run and disconnect the battery, but pulling the red fuse is much easier.gameover said:Can't I just disconnect the battery? :confused
It seems to be a pretty universal thing for GM so I'd guess it will work on an LS2. The red fuse part might be 04 only I don't know (it's really just an easy way to kill power to the PCM only). But the put the key in run and unhook the battery is very universal to GM.Braman'sGTO said:will this work on the new LS2 engine? I have a custom intake that allows more air than the K&N and the NewEra, when we were testing it the ECU/PCM sensed the extra air and just started dumping in extra fuel to make up for the extra air. Does this somewhat work inplace of a tune until one can be proformed?
