I have a 95 z28 that is getting a motor built right now. I want to go with a stall high enough that I can spray N20 right out of the hole. Is my OBD1 computer going to cause trouble? Or is it just a few cars? Should I go with a ~3200 stall and hope for no trouble? Also, what fixes can I do?

Sorry I have so many questions but I read up on it and am still confused. I can't figure out how common it is and how often these "fixes" work. I don't want to get my car together just to have to spend a fortune getting the stall to work.

Thanks a ton

Some cars don't have the problem, but most do. It also doesn't seem to happen on regular street tires, but mostly on slicks/DRs.
The software fix works on some, and it doesn't on others.
Ed Wright supposedly has a fix for the OBDI now that will work.

I also offer a cheaper alternative by converting to OBDII if all else fails.

 

Or, use a non-electronic transmission with a manual valve body so you bypass the computer by programming out the transmision controls. I have an M6 computer in my car and a 3600 stall.

 

How much does this fix cost? I was planning on contacting you about tuning my car once I get it back together so should I do all of it at once? Are there any downsides to the OBDII conversion like being forced to use expensive scanning software etc?

Thanks
Dustin

 

Dustin,
The OBDII conversion consists of an OBDII pcm and programming.
If you provide your OBDII PCM, then it will be $125 + shipping.
If not, it is $225 + shipping.

This does include full custom programming for all your modifications.

Unfortunately, the downside is not being able to use the cheap scanning software. You will need autotap for it.
