how could a person make two mass air flow sensors work on the TPI system?

I dont think you can 2 MAF's because there is no harness connection for a 2nd MAF and the ECM will not recognize 2 MAF signals coming in. I saw a GTA with dual cold air inlets coming in to his TPI throttle body, but only 1 had the MAF attatched.

Two MAFs could be paralleled on a TPI system if an interface circuit was designed to sum the two MAF inputs, and then scale the resulting sum to a 0 to 5 volt range as an output. The PROM would also have to be recalibrated so that the 0 - 5 volt MAF input would correspond to 0 - 511 grams / second, instead of 0 - 255 grams / second.
