maf sensor bypass
i have an 85 t/a with the 305 tpi, is it possible to bypass the maf so i can put a different air intake on it, if not is there a true cool air intake i can put on it?

Some guys in the DIY PROM section have swapped some code on the chip to convert to run SD instead of the MAF. I don't think it's difficult, but you need to be able to burn your own chip and make some code changes with a hex editor to your bin file.

That MAF conversion to MAP using the stock ECM is brilliant. I did the conversion and had to get a new computer and whatnot. Why try to remove a working MAF? If you want cold air intake just keep it plugged in and get some more piping and make your own- keeping the MAF in there somewhere.

Personally, I would swap to the '730 ECM. That way there is no MAF and you have the benefit of using the ECM with the most DIY info available for tuning, etc.
