MAFT+ dyno tuning results are good.

I didn't have a wideband to use, so the fuel numbers are conservative. We plugged in autotap the night before and went for a spin...94 octane...and with 6% lean we saw the O2 voltages hitting low .800s so we didn't go any leaner.

Dyno results...

6% lean and adv 4 deg of timing got me 8rwhp and 12rwtq.

4% lean and adv 6 deg of timing got me 9rwhp and 11rwtq.

0% lean and adv 8 deg of timing got me 9rwhp and 4rwtq.

All the timing numbers came from the practice of advancing until the numbers stopped increasing and backing off one.

I probably could go 8% lean without problems but don't want to risk it without the wideband.

Very interesting results. This is on an n/a car.

Next weekend i'll take these results to the track to see if they equal a 10th or what.

One question... should I add octane boost and try advancing the timing another 2 deg at the track?

Glad it's working out for. Those are respectible gains for a bolt on car.

I wouldn't use octane booster it doesn't work properly like you would expect it to. Possibly run race gas if your track sells it, that will give you a LOT more room to play with advance.

Also were you looking at your knock retard?
Thats the other thing you're going to want to keep to a minimum if any at all.

Yeah... we stopped with timing as we started to see knock. I was hoping to advance more than 4degrees but the knock started.
