Default S-AFC2 question

Ok guys I need som help with the settings. I need to know if the Hi & Low setings are the same? or are the low setting negative and high settings positive?

Please give me a quick list to follow.

Ps: I'm using the setting as they are in FAQ for both High & Low is that correct?

hi and low throttle settins refer to your throttle position. if you choose 40% throttle to be the crossover to high throttle, then once your throttle is 40% open, it will cross over to the 'hi' part of the settings that you set. generally you want a little more fuel in the 'hi' throttle settings b/c that will more than likely be when you're getting on it.

So does that mean if I have the FAQ settings for the low the settings for the should be slightly higher?

i would add maybe like 3-5% more fuel in the high throttle, but i'd definitely get a wideband on it, afc's can be deceiving

Well, I dont have a lot of experience with AFCs (because I despise them) but if you make them different(hi/lo), and if you add more fuel in the high throttle, you are adding more timing as well. Yuck!

actually you're taking timing out. by adding more fuel, you will actually be getting closer to '0' correction for the injectors, the closer you are to 0%, the less your timing is affected. if you run an afc with 0% correction, say for stock injectors, or if you're running another program to control your injectors, it doesn't affect your timing.
