just did a l67 swap and uploaded a dhp 1.5 to my pcm ....took it to the muffler shop to exhaust shop to weld 3 inch piping .....all of a sudden car doesn't start windows don't go down nothing to radio and port where you plug in dhp tuner inoperable also nothing to fuel pump....look under dash to bcm and 3 lines to bcm are cut and frayed ...my question is if i buy a new one it says has to be programmed to prevent drive ability issues...is this something dhp can do or am i screwed with dealer only....i am going to cross thread this in tuning as well
 


DHP can do nothing with the BCM. That is something only a Tech 2 type scanner from a dealership will do.

Why can't you just fix the wires going to the BCM?
 
dhp cant do that.

only a dealer can, and thats a maybe. fix the bad wires, see how it goes.

check all your fuses too, the welder may have blown one.
 
checked fuses and fixed wires......but nothing inside is operable i have lights and chimes .even with key removed and door closed lights stay on had to unplug battery
 


that harness can cause all sorts of issues, from no fan speeds but 5, parking lights not working, not starting, interior lights staying on.

you try to jump the starter yet to see if it will run even?
 


changed the rap relay and voila the car started all windows radio and such worked ...turned it off and now the fuel pump isnt going ....can anybody tell me how to do a case relearn with dhp i cant seem to find the option for live tools
