Post your S-AFC settings; compare

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?

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.
