So I have a 6 pos chip plugged into the back of my PCM like normal earlier this morning I blew out my 3rd PCM... What is causing this cuz if I can't fix it I'm moving to OBD2 tuning... Any ideas? Thanks in advance.

 

It has to be loose or just not getting a good connection unless the chip has a short somehow IF it is a chip problem. Have you checked for any chaffed wires coming out of the main harness?

 

What is "blowing out" a pcm? What is the actual failure?

chip installed improperly, someone removing the chip while the key is on? mismatched tunes?

 

Ok sorry for making yall wait so long but ive done a few upgrades in the meantime.
as for the PCM it was the #30 fuse for fuel bowl heater causing the PCM to short out... solution removed fuel bowl and made a DIY regulated return.

after solving that problem she had absolutely no power so FASS 120GPH@55psi went in
so happy days me haha just figured yall would want an update

 

Except now the truck is in pieces and awaiting a plethora of "cool guy go fast" parts. Sorry bud i had to chime in.

And before you guys ask... The list is shorter if you ask what he is not doing to the truck.

 

Haha dig up an old as h*** thread but yea he is right
and the sig gets longer
