Can you electrinically adjust left right BLMS
I have seen allot of 92/93 Vettes with the left being different that right BLMS. I have had this situation in my 93, on 2 different motors, 2 different exhausts. So, can you have the chip tune it so both, at WOT are running the same?

There is a way to adjust the injectors on each side, however, what I have noticed is as the tune gets closer to being correct, the BLM's will start to come together and will end up within 1 or 2 of each other. Mine runs one at 128 and the other at 129 when the mixture is right. I have had it where one BLM was showing 130 and the other would be 158-160. No other changes but playing with the injector constant and timing tables.

How do you get the "tune" closer to being correct? Do you use data from your car, and have atuner adjust your program? If so, who did you sue and what data? Steve

Well, mine being a '94 I can change the program myself, but the same programming strategy holds true for the '92-93 models. You just have to have the right chip burning software. Craig Marcho may be able to do '93 models, but I am not sure. When I had my '92 I had Ed do a chip and he got it back 3 times with Diacom data to tweak the program with. By the last one, he had it pretty square.

Thanks, I had Ed do the chip that is in there now. He has it to where it is runnign real well. But after looking at the Diacom files, I am sure there is more to tweak. Did you have to jkeep sending the chip back? Or will he do one, and have you send the old one back after doing yours?

I sent him the chip back before he sent me an update.
I also sent you an email with some reference material that may help you understand a little bit of what the tuner has to work with. ;)
