heLLo everyone... i was just wondering if anyone had a clue what was going on with my computer..... weLL my orginal computer went out so i had to get a rebuilt one..... the truck runs fine stock with the rebuilt computer...when i try to plug in my chip it just throws a CEL light and wont start???? all connections are clean and free of coating... i also tried a downloader type chip the evolution and even that made no difference???? the evolution downloaded into the computer but when you drive the truck there is no difference in power... just feels lyke a stock truck again???? could there be any reason why that computer wont let me down load a chip in it???? thanks everyone!!!

 

sounds like a possible bad pcm, who rebuilt the pcm? how old is it? what was wrong with the first one?

 

hey thanks there... ummm i got it from these guys that sell on ebay and stuff... auto computer exchange???? they rebuild idms and computers...ive ordered a idm from them once annnd it was alright.... buttt the original one the truck would die out intermittenly...... run fine for a second die out... some times wont start... and some times it would... with this computer they sent me the truck runs fine stock.... just wont let meee install chip or downloader...

 

Did you get the right one ?..What happenedwith the old one ?...

Did the chip work before ?...
