MAF Translator version 2.01 discussion, What are your thoughts and findings Options

[awd4kicks]

I've had a few discussions now about the MAFT 2.01 tuning methods. Tuning with Version 2.01 is obviously different than previous versions.

I'm interested in opinions from those that have experience with the 2.01 MAFT or from those that have researched it anyway. I'd like to hear your experiences with the newer version and if you have found things that work or do not work for your purposes.

I look at fuel trims as fuel economy basically, because that's how the ECU looks at it. Its trying to get you the best possible fuel economy while keeping performance on par with what's expected from the car from its own point of view (namely 200 ponies from the factory). If you are tuning your fuel trims you are tuning for gas mileage. At WOT the fuel trims have no effect on the performance of the car because the ECU switches to open loop. If you aren't interested in gas mileage, don't worry too much about the fuel trims. Kris is interested in gas mileage so obviously it is a concern for him. From my experience, the only dials you can adjust to change your fuel trims are the base, idle, and mid to a point. You may be able to lean out your low RPM tunes to improve gas mileage as well, if using the RPM dependent tuning.

Tuning for WOT performance should still be based on knock, timing, FI DC, and if you have it a WB 02 sensor comes in very handy. Obviously tuning her on a dyno should yield the best results.
