First things first. If anyone is/knows any one in Houston (north side preferably) that has the necessary cable/ equipment to tune an OBD1 LT1 PCM, I really need your help. I have the tune already to go, just can't get it on my new PCM.
Now for the "question"
I have a 96 LT1, with an OBD1 PCM. Last night I swapped rear ends (M6 kills 10 bolts) and went to tune it at about 1:00AM. I have a brand new cable which I've used about 5 times. Its been giving me some small problems with connecting to do data logs, but once it connects its great. Well last night I took my car for a cruse and after about 15 of driving it finally synced with my PCM. So I pulled over to tune it via tunercat. About 3/4 of the way through I got a "cable failure" error. Bam. Done. Goodnight. Dead PCM.
This morning I drove to LKQ and pulled another PCM, took it home and tried to flash it. This time it "established connection" right away and started flashing. Crapped out again, but only after about 1/8 the way through. Two dead PCMs.
Now I have PCM #3. I can't get it to read the tune off of it (just to know if it will communicate properly), so I didn't dare try to flash #3. I am having connectivity problems with three laptop. One XP, one Win7, and one Win8. All can't connect in data master(or w/e its called).
I haven't changed any settings for my Com port, The laptop used for tuning is running XP and is mounted in my car, therefore I know the settings haven't been changed. Everything is at the default, I also tried changing it to a baud rate of 54000, with no luck of communication.
Does this sound like a bad cable? I also checked all my fuzes, all good. I'm really desperate, I'm willing to pay almost any price, as well as throw in a OBD2 cable.
