In my recent efforts to do a few things to my car with tunercat something strange happened. I have the car not running with the ignition on and the program I want in the PCM loaded up and I go to tools then program PCM its starts to work sayin gits reading or contacting pcm or something a few blue bars flash up and then it says error pcm not responding..ok its happened before forgot why so I tried to figure it out didnt change anything and couldnt figure it out so I try and start up my car and it wont run for crap..... Just wondering how I enable it to read the pcm so I can get a ride back to my car and put the program I want on it so it will run. Thanks!

 

Sorry, but sounds like you fried your PCM. It will need to be repaired before you can use it again.
I fix them if you're interested. Check my website's order page under PCM repair and socketing section...

???? fried how the hell does that happen...how much to repair it and how do I know for sure if its fried I mean it runs and starts but it stays running but not all that well I wouldnt want to drive it around or anything. I dont see how its fried I mean i didnt do anything out of the ordinary unless its just that random and unstable. All I did was load what I wanted and click program pcm nothing else on the computer was running except tuner cat...?????

 

Man, I'm sorry, I don't really understand what you mean. If you started programming and it interrupted somewhere during the process, then the chips inside it need to be desoldered from the board, reprogrammed and soldered back.

 

hmmm this is wierd it didnt say it was programming yet it said it was trying to contact the pcm an dthen said error pcm not responding an dnow it runns really rough... anyone ever heard of something like this.... ok another question that may help me out some people have trouble when they are using tuner cat for the first time getting the computer to contact the pcm or read it or whatever, what is generally the problem or possible problems i could check out, i remember one being not having it read from the right com port. RRRRRG everything is falling apart on this car lately...

 

OK, it might not be dead then.
Try to pull the pcm fuse and/or negative battery terminal, let it sit for a few minutes, then connect everything back and start the car. It should be ok.

 

ok thanks ill try that ::crosses fingers:: anyone got a clue why it says it cant contact the pcm?

 

Because it lost communication and it needs to be reset. By pulling the fuse or the battery terminal, that's exactly what you'd be doing.

 

ok hope this works Ill just take my moms car to where it took a **** and see what I can do thanks again!
