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

so : low 95 high 100
ill give it a try thanks.

 

When you install the turbo, you can the pressure signal for the throttle input.

Actually, you could do that now..

 

do you run the TPS line to the pressure input, or how does that work? Still working with my SAFC

 

i too am lost with this. exactly what do you mean? do i need do this? what does this benefit?

 

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.
