PCM tuning options with a 98...
PCM tuning options with a 98... What custom tuning options do I have with a 98 Z? It is my understanding that LS1 edit does not work for 98's? Is this true? What do you guys use on a 98 to change fuel curves, etc....?
TIA,
Joe

Re: PCM tuning options with a 98... There is hope .....
I may have been the one that started that nasty rumor. It seems the very early model 98s need to have the PCM reflashed at the dealership with the latest revision in order to get LS1Edit to recognize the PCM.
After I had this done, Thunder Racing was able to program it like any other LS1.
Yours may need a PCM re-flash, but, it may not need it too.
Ron,

Re: PCM tuning options with a 98... So basically what you are saying is that I can go ahead and get LS1 edit...one way or another I will be able to use it on my 98 PCM. Hopefully I don't have to get it flashed, made in June of 98.

Re: PCM tuning options with a 98... Don't worry... Go ahead and get it. You will be fine.
The worst that can happen is that you will have to pay a dealer about $55 to re-flash the PCM before your LS1Edit will work. After that, everything will be fine.
Again, your car is a late year 98. I doubt you will need a re-flash at all. (my car was built in Aug 97)

Re: PCM tuning options with a 98... Okay, I will go ahead with it then.

Re: PCM tuning options with a 98... Mine was built in March, no problems here. I do remember Ken asking for folks to help finding very early flashes. Most couldn't help as they had been updated at some point while in for service. Very difficult to get copies of the earliest flashes.
