I'm sure there are some of you that know what this is, but for those of you that don't know, I'll explain. It's a device used to adjust air/fuel ratio. It taps into the mass air flow sensor and tricks it into reading different readings. It is has two settings: base and WOT. Both are adjustable from 50% rich to 50% lean. Yes it is designed for the F-Body and the Grand National, but so far it seems to work on my car. Before I put it on the car, my AF meter used to read about two bars into the rich side. I put the MAFT onto my car and adjusted to 15% lean base and 4% rich at WOT, making it 11% lean at WOT. Now my meter has been reading right in the middle of Stoich. It seems to work so far, I am going to adjust it more lean once the computer gets used to this setting.
How did I come upon this? Well, I work with a guy that has a really nice '99 Formula. He was telling me about the MAFT he had on his car and what it does. We went outside to look at it and it appeared that it would plug into my MAF sensor no problem, so we tried it and it worked. He's letting me borrow it for a couple of weeks so I can decide whether or not I want to buy it. He will sell it to me for $30. They go new for $150.
I'll let you guys know if it works out. So far it seems to. I just thought I would share this, because it is a very inexpensive option to buying a fuel pressure regulator and a chip. You can find them used for anywhere from $50-$100 on the F-Body sites.
