I investigated after Wayne suggested I try the SG-II, but found that my car won't accept it due to the fact that it was made before 1996.

Needless to say, I've had to do my experimenting in less than ideal circumstances. Along the way, I've learned to guess roughly what the impact to my MPG will be if I perform certain actions. I've even developed a few techniques for FASing and P&Ging automatic cars without damaging the inner workings.

It hasn't been easy, but it works.

I've even developed a few techniques for FASing and P&Ging automatic cars without damaging the inner workings.

Please would you go into a bit more detail about your FAS technique?

I hear ya on that, ascribe! But I still like my little old car. And I can pull some decent numbers out of it when I'm doing it right.

FASing an automatic works best if you have level ground and a stop ahead, or a hill that will take at least 15-20 seconds to descend.

I don't P&G with the engine off - I leave it in neutral. As with FAS, I only do this on level ground or a slight downgrade (or a hill shorter than 15 seconds).

Just to quote what I posted to another thread:

Here's the secret to automatics. You can't just put it back in gear when you bring it out of neutral. The computer will automatically select a low gear, then shift up. If you rev match improperly you will damage your transmission.

At 55 mph in Overdrive my car turns about 2250 RPM. However, at 55 mph in Drive, it turns about 3300. So I rev match to 3350 or a little higher. (Don't over-rev and don't suddenly punch on the accelerator; let it gradually increase, and hold the gas down at a point where the RPMs stabilize at just the right number.) The computer kicks the throttle down (as automatics are designed to do naturally) and shifts it back into Overdrive with no sudden revs or "kicks". I also find that this is much easier if done on level ground where the car's engine isn't having to pull.
