parish8 - After doing some digging it looks like the 0-5V signal is converted internally in the MAF to a frequency and then read by the computer. I emailed Steve again to see if there is anyway his controller can be made to work with this setup. I'm guessing some sort of frequency to voltage converter will be necessary though. Any electronic gurus out there?

Yelo - I don't know about. It might be Ok in small amounts but, I've never heard of a water/alky kit on a N/A motor.
