Sensor check 1 reads 3.8v
Sensor check 2 reads .15v wich is for skylines and crap
Sensor check 3 or Throttle reads 3.9v

I will post back with my other readings in a few minutes.

89GXL N/A ---My A/F% readings are 50.7% WITHOUT S-AFC tuning.

My RPMs read almost exactly the same now. At 2000rpm its only 100-200 rpms off. Last time I had A Safc conected I had like 400 off. I think my cars tuned better this time...

The voltage for your throttle sounds off - do you have it tapped into the wide-range throttle position sensor? With the car warmed up and the throttle closed, it should read around 1 volt.

The stock tach is usually a little off from what an electronic device will read, but that's usually not a big deal.

Oops mabey thats not throttle. Mabey its TPS. Thats what someone from the other S-AFC thread said.

Sooo ??? is this good. Voltage 1 is AFM voltage I think. Whats number 3. The percentage of throttle is actually displayed in monitor mode.
Anyone?

Anyone?

Another ? is My settings on my S-AFC seem to change when I start my car. I set the throttle points to 60-80% low high but when I got back in my car the next day it was 36-50.. I was like WTF how did this happen?

Throttle is the same as TPS.

The Super-AFC learns the TPS to some extent, so it might have altered the settings to compensate. Not sure there.

Anyhow, I would double-check that voltage on the Super-AFC to make sure you tapped into the right wire - you should see the voltage change as you push down and let off the gas pedal. If you have an '86-88 car, the TPS is fully open with the gas pedal only about 25% of the way down.

i noticed every once and awhile the SAFC would read weird things. ie) TPS would read 50% at idle, and airflow would read 90% at idle, I'm not sure why this was.

mine is worrying me.

2000rpm 1800rpm SAFC
3000rpm 2700rpm SAFC
5000rpm 4600rpm SAFC
6500rpm 6500rpm SAFC

set to 4 cyl up.

why is my thing off so much around midrange?

your tach is wrong. most cars are. you speedo is wrong too...
