PMT2

[Degnol]

So, I've heard it is plug-n-play, but specifically, should I D/C the batteries? Do I need to have the PCM reflashed? Or am I worrying too much and just remove and replace? The old PCM is an XLE, btw.

I guess your change out your PCM, yes I'd disconnect the batteries.

ALWAYS disconnect the batteries when dealing with the PCM

Disconnect the batteries if you want but make sure to keep the key out of the ignition. If you have the key off, there is not power to the PCM. I have pulled PCM's many many times with the batteries still connected. Just make sure you DO NOT have the key in the ignition.

And yes, the PCM is a plug and play. I run a PMT2(with tunes) in my truck.

do tell.. why is the pmt2 so special? im curious.

[Jarrod B]

the pmt pcms (pmt1,pmt2) are the easiest to tune and have the best results. however theres some others that will work. but this one is the perfered one.


i dont unhook batts for mine. just make sure the keys are out of the ign and out of the truck. door closed and no power related stuff running. then pull pcm out and swap. gtg

ah i gotcha.. yeah i dunno what my 02 is i think its a VDH4 or whatever that one is, i havent had a chance to look, it actually drove pretty nice stock, cant wait for my php tunes though.. we shall see.

pcm swaps are only beneficial for our early 99 trucks.
