The MAFT Pro features are not part of the normal Stage 3 chip, I consider it to be an add-on feature, like the Cyclone Control, NO2, etc, so I charge $25 extra for the work I have into it. So, if you have a DSM, and don't already have a chip, the price is $115 + $25 = $140. If you have a GVR-4, and don't already have a chip from me, the cost is $FREE/Donation + $25 = $25+. If you already have a chip, and all you want added is the MAFT Pro features, the cost is $20 upgrade/burning/mailing fee + $25 = $45.
In addition to locking the BARO and IAT voltages in the code, as I already do for MAFT owners, this chip also has timing control on the IAT input to the ECU. The MAFT Pro unit will send a voltage to the ECU from 0-5 vdc, with 5 volts meaning NO extra timing, and 0 volts meaning 16 degrees advance on top of whatever the maps already call for. The extra timing gets phased in as the boost rises from 0psi to 7psi, and you can log the extra advance in MMcD if you add D4 to your address preferences. Mike and Bob at FullThrottle say they have some neat ideas of what to do with the unused BARO input also.
