#19508, "Hey Corbin: Question about your SAFC boost mod"




          

Hey Corbin,

I'm trying to setup my safc on my car with your boost mod (the add on to read boost instead of tps voltage) and I have a question or maybe a problem.

I am getting confusing readings as far as the throttle percentage. With the car off (0psi), i get about 100% throttle position. The voltage from your sensor is about 1.5v at 0psi.

With the car on at about 19mercury of vaccum, i get ~29% throttle position.

I took the car out without the map connectors hooked up so i can see how the afc is reading the car, and at way before full boost (about 9psi) i hit 100% throttle position.

Is this normal? I am not getting about max of 64% throttle at 7.5 psi like your instructions says.

Thanks for the help. If you need more info, just let me know.

Nevermind. I had the boost mod hooked up to a 12v source instead of a 5V source. Now it works PERFECTLY!!!!!!

Now to the hardest part - tuning it!

Like his instructions says, the map sensor + wire. I just got the color of the + and - wires that go to the map sensor, and then looked at the ECU side of the wire. Both + and - wires are on the LOWER connector to the ecu.

Sorry I didn't get to this in time (gone on business). All of this should be at:

http://www.houstonhardware.com/~cbehnken/foolafc.html

I added a diagram to the site recently which makes everything much more explicit. I am now including this with the sensor. I am always updating my pages with new information.
