While the MAF adds a whole level of complication, fabrication, wiring and PITA factor - it does let the EEC make a very good guess as to how it should run your engine. For the first tests I used the stock MAF from the Stang with the stock computer. So the EEC was getting real air flow numbers. Even with the larger injectors in the DOHC engine (24lb vs 19lb) it ran fairly well.

I had the IMRC connected to a toggle switch since the stock EEC won't switch it. I was having trouble finding software to tune the Strategy my 96 was running so a trip to the wreckers yielded an EEC from a 97 running the CDAN4 strategy. I found software support with Binary Editor for tuning and EEC Analyzer for datalogging and analysis for this EEC. It took me a while to learn this Ford tuning stuff. For a long time the stock tune ran better than my custom tunes. But eventually I got the hang of it.

A trip to the drag strip produced 6 runs at 97 mph, best time of 14.5 sec. Turns out I hadn't disabled the speed limiter - it starts pulling timing at 90 mph and shuts off fuel at 100 mph. :(

Since then I've gutted the MAF for more flow, put on a Magnaflow cat back exhaust and done a lot of tuning. It pulls a LOT harder above 5000 RPM than it did at the drag strip. EEC Analyzer has some fun tools like virtual drag strip and a dyno calculator. Here is what it calculates

Take it with a grain of salt ;) I have been reworking the MAF Transfer table to get rid of that lean spot. Probably the single most helpful tool on EA is the MAF Calculation tool. It calculates MAF comparisons like this

The bottom row is volts from the MAF and the side numbers are airflow. The yellow line is the new calculated MAF calibration. Notice the little spike it put in to correct the lean spot. Cool 8-)
