I have a head / cam swap coming up here this weekend. Problem: I know I will be maxing out my stock injectors and with the cam I'm using (233/239 .569/.577 110lsa), the computer will definitely need tuning. What kind of experiences have people had with www.pcmforless.com ? Is the conversion to an OBD1 PCM really worth it? Is there anything involved in the conversion other than taking the OBD2 pcm out and plugging the OBD1 pcm in? Thanks in advance and would appreciate any input you might have.

 

I have been using PCMforLess for 2 years now and have been pleased with the performance. The tuning is money well spent. I'm not sure about the OBDI conversion, I left mine OBDII and just had some of the extra sensors turned off.

Hope this helps

 

I just used pcmforless and I'm glad I did. My car hasn't run this good since it was new. Throttle responce is great.

 

What kind of turn-around time did you end up with? Couple days? A week?

 

PS: does PCM for less do any "part throttle" tuning? I assume that is a bigger issue with a bigger cam . . .

 

If you buy a cable (for obd1 PCM's), them you can have your program emailed to you. I think he also offers OBD2 to OBD1 conversions. It's worth it (if you dont have a high stall automatic) because OBD1 software is so much cheaper.

 

I was rather concerned that the switch from OBD2 to OBD1 required that I eliminate my crank sensor. How big of a deal is that?

 

The sensor can stay there, it just wont be used. You dont need it, it's only there to detect misfires which you can do with you senses. The swap might be an issue if your state does obd2 scanning though.
