I've been browsing the Focus FI forums for more info/ideas on boosting my Zetec. Instead of running larger MAF units, they are just using a Diablo MAFia. It's runs about $160 so it seems like it would be a nice alternative. It's got me wondering tho...

I always tought that once you maxed out your stock MAF, that was it. It only put out 0-5volts. Does the MAF actually put out more than 5volts when pushed farther than it's stock limits? ..and the MAFia is just scaling that voltage range to 0-5volts? A range that the PCM can understand.

How do you calibrate that to something like the SCT ProRace software? Is it just a guessing game as to what transfer function that you are running?
