98 t/a sucks, with friend on dyno and computer took a ****!!!!!! tell me your story!!!!!!!

 

are u drunk?

 

I've killed 3 ls1 pcms in a 98, but it was learning how to develop flashing hardware/software and having a checksum issue. (P0602/P0605 code)

Since then, I have flashed it hundreds of times, without issue, using SCT, HPT, EFILive, and Tunercats.

Now I just run my roadrunner in my 98 car, since it is live tuning.

thanks slow!! i think my friend was ripped off by a no name tuner!!!!!! and then the tuner made him pay full price plus the cost off the new computer and cost to flash vin# p/s YES AM VERY DRUNK!!!!!!!!!!!

 

98 pcms don't hold VIN information - Extra pain / fail.

 

the 98's shoud hold vin information, but not in the 512k flash chip region

 

I have tuned 98 PCM's countless times with no issues. Just don't kill the car or laptop batteries.

 

And don't open or close doors, turn on radio, hvac, etc.

I haven't had one single failure flashing, but I take all the necessary steps you should take to try and minimize risks.

 

thanks guys for all the input......looking back the guy tuning the car was in and out of the car, alot.......i know what to watch for now!!! I THINK.....

 

Best bet for 98's is to get and install a 99- up PCM. That's one of the mods that I need to do.

 

TCS/ASR will not work when you do this, I swapped in a 2001+ (12200411 pcm) and it had no noticable difference, so I swapped a 98 back in.

It I could have kept TCS and the wiring harness wan't all mangled due to the extra length, then I would have kept the 99+ pinout.

I have no TCS/ASR. There won't be any noticable difference between the two power wise but it's much easer to tune 99 and up pcm's compared to tuning 98's. That's the only reason for it to be done IMO
