S-afc Ii?

Has anyone ever installed a S-AFC II into their escort gt(x)?

yup, I have a gtx motor ecu and harness though

[EscortNation]

I also have. http://ohhhchhittt.proboards25.com/i...ead=1109056824

They suck.

What sucks?

if your car is a manual and you don't have the GTX throttle body, the TPS is not a variable potentiometer and it will be more difficult to tune the AFC

True but running it off the TPS signal is crappy anyways. Best way isto get a 2 bar GM MAP sensor and connect into that. This way it reads of engine load and not TPS signal

But will a GM MAP sensor work with a stock/gtx ecu or just stand alone?! I assume the later!

[elscotto80]

The MAP sensor goes right to the SAFC, it will do nothing for the GTX ecu since the GTX ecu cannot read a MAP.

[Lex]

The TPS is a secondary input to the AFC allowing you to have several calibration curves. - no one seems to get that. The AFC reads the AIRFLOW SIGNAL and mofifies that signal and then sends it to the ECU. The airflow signal is the only signal the AFC modifies and interrupts. If you use a MAP sensor you are replacing your VAF with a MAP sensor.

[mikeflys1]

You're not replacing the vaf with anything.....The MAP sensor is ONLY routed to the safc's tps input. Nowhere else.....Its just so that it switches maps based on load and not just throttle position. And it makes it easier in his case where the 5 speed doesnt have a real tps.

elscotto just couldn't tune it right. I have one right now on my turbo'd BP and I love it. as soon as you figure out how to use it and use the Map sensor for the TPS everything works right. Have not had any problems.

[elscotto80]

Ehh i had a good idea, but I was lazy. You really need a dyno to get a good tune.

Hahahaha, everything needs a dyno for a great tune. You can have a good tune and make plenty of power. But I would not go over 10 PSI without dyno tuneing. That is just me thou. I just don't want to blow a head Gasket.

SO, have we come to a conclusion about the S-AFC II and how to hook it up? And weither or not I need a MAP Sensor or not?
