is my throttle setting ok?
when i monitor my settings my throttle hits 100% at like 1/4 throttle. is this normal or did i set that wrong? i think my throttle points are 30% and 60% if that matters. now keep in mind that ive only had it for 2 days so someone please help!

you must have a s4. Your throttle is correct. But your thorttle points are wrong. they should be, LOW Point: 95%-98% HIGH Point: 100%
if you have your low point set at 30% and your high at 60 %. then between 30 and 60 percent your AFC is not controlling anything according to your maps. its makes up a fuel map to merge between the low and high throttle point. Now if you have a S5 TPS. You could have your low point at 50 and your high at around 60-70. The reason you want S4 at 95 and 100 is because at 1/4 throttle its reading 100%. so if you set your low at 30%. you are letting it only read 30% of the 1/4 throttle range and not 30% if the entire throttle range as you would get with a s5 full range tps. 1/4 throttle is about 25% right? so you can imagine how little throttle you are giving till you hit 30% of the 25% throttle.
Just a FYI

Actually, you could do that now..

The TPS signal range is from about 1 to 5 volts.
The pressure sensor range is also from about 1 to 5 volts.
Fuel needs are actually more closely related to MAP that TPS.
The THR input on the S-AFC is cool with either.
Just tap the pressure signal instead of the TPS signal.
I tapped both into a switch so I could switch back & forth to compare the two.
