Before I go carb I may consider buying one more MAF. The speed of my supercharged L98 varies from day to day and I think its related to the MAF or ecm. No, Im not going to buy a dfi set up or spend gobs of cash. I have the carb set up and its sitting there waiting to get hooked up.

Wells makes a higher flowing, tougher MAF, but a new MAF probably won't help you unless the only problem is that yours is dead. Your 165 ECM can only read 255g/s of air. You could (or have someone else) program your stock chip and make things run a lot better, but you will never truely be metering all the air going in. Are you running the stock chip now? You could also go with a FMU of some sort. After reading your previous posts, I think you've already decided.

Aron,

What is the most cost effective way to fix my car? I already have the carb set up. I will be buying a c5 in the future and know Im not getting any kind of cash out of the vettte I currently have.
Suggestions?

you can install a gm '730 map system, get diacom, pocket progrmer, eprom eraser, and such and burn your own chips for a map system.

ok,

how much and do you think it would work on a blown motor???

Thanks,

Matt

On a blown motor, you'd want at least a 2 bar MAP setup - I don't think that's been done for the 730 yet. The 730 conversion can be made for much less than $100, but you then have to get into chip burning. If you have the carb setup and you can make it work, that would be the cheapest. If you drive the car to Sarasota, I'd get it running for nothing. If you pay a 'custom' tuner, you'll spend $400 or $500 and get hit or miss results. If you burn chips yourself, you could get it running for $200 - $300 and a lot of research and tuning. The 165 ECM isn't the right way to run a blower, but it can work.

Let me reiterate, when you sell it, let me know.

As far as the Wells MAF, search for Wells on the net or search the archives at thirdgen.org or here. Someone left contact info for Wells.

Again, it will work, but 255 g/s is all it can read. After that, you're just kludging fuel to try to keep it rich. Kinda like an FMU in the chip. There's a lot of people running blowers on stock computers successfully, they're just not reaching their full potential. The right way would be a MAF translator or newer MAF system that can read 500+ g/s, or a MAP system with 2 or 3 bar capabilities. Since Red5 doesn't want either and probably doesn't want to spend $500 on a custom chip or drive to Sarasota, carb will probably be his best bet. Although, a carb will require lots of changes and tuning also.
