I am just interested in the different settings of the S-AFC on their SC300. Here is mine:

High:
1000 rpm = +4%
2000 rpm = +4%
3000 rpm = +4%
4000 rpm = -6%
5000 rpm = -6%
6000 rpm = -6%
7000 rpm = 0%

Low:
1000 rpm = +3%
2000 rpm = +3%
3000 rpm = +3%
4000 rpm = 0%
5000 rpm = 0%
6000 rpm = 0%
7000 rpm = 0%

NOTE: Do not use this configuration as it may demage your engine.

OK, Here's mine, but I've just started to tweak it. I won't have my A/F meter installed until after Christmas, so that's when I'll get serious with it. For now I was just tweaking to see what effect it had on gas mileage (as a way of judging how much change the S-AFC was producing).

High:
1000 rpm = +0%
2000 rpm = +1%
2500 rpm = +2%
3000 rpm = +3%
4000 rpm = +3%
5000 rpm = +0%
6000 rpm = +0%

Low:
1000 rpm = -3%
2000 rpm = -3%
3000 rpm = +0%
4000 rpm = +0%
5000 rpm = +0%
6000 rpm = +0%
7000 rpm = +0%

Also, my low setting is 20%, high is 50%. I noticed cruising around easy, my throttle position runs between 5-15% and I rarely get above 2500 rpms.
Playing around is a different story

Wow, they are somewhat different than mine. Isn't it dangerious playing with the settings like that?

Do you guys have Dyno sheets on how much difference the AFC made?

Thanks

I did it over a year ago. I will most likely do it again sometime later.

A 3% change in the airflow doesn't seem to make much difference. I don't want to go more than that until I get my A/F meter installed.
When I finish installing the rest of my goodies, I'll take her to a dyno for real tuning.
