Where would the pcm be in a 2007 QC Hemi? Does it void warranty if reset Thanks

 

the reason is i just installed magnaflow 12288 last week SI/DO. Would resetting make a difference?

 

you dont need to reset the pcm when you do an exhaust. only when you make changes to the engine like intake or pulleys. but if you want to reset the pcm. pull the neg battery cable off. turn key fully to the start position and hold it for 20 seconds this will clear anything. next reinstall battery cable and start and stop truck 3 times. on the thrid time leave truck running for about five minutes then take it for a ride

 

there is another post somewhere also, take the pcm fuse out, get in buckle seat belt turn key on there will be two chimes after that turn off and replace fuse, thats what i did and i don't belive there is anyway for them to tell if it has been reset.

 

wat is the pcm fuse?im guessin i need to do this since i have a cai and exhaust

 

it should be labeled in your fuse box in the engine compartment. Will probably be called PCM/TCM
