The MAF is not re-calibrated...it's pure stock MAF.

but that's a very good question... as far as i know, since the autologic chip is a piggy back, it probably sees the 5 volt cutoff, and then switches to pre-determined RPM/Fuel tables... or that's what I would lead myself to believe.

Are MAFs capable of sending a higher voltage than 5V? I haven't read how the actual sensor works, but I got the impression that it works like O2 sensors... which are limited to the signal they send because the way the sensor works.

If the stock MAF can send over 5V, could a computer (be it autologic or SCT) transform the values over 5V with tuning? in which case me buying an SCT chip doesn't require a new MAF?

I get the feeling that 0-5V is the optimum operating range of a MAF regardless, and the SCT's ability to work with a non-calibrated MAF was due to the fact that you could transform those values below 5V properly, but still work under the 5V cap.

This bears some researching...
