Ok...I installed and setup my S-AFC II. My butt dyno tells me that it's not as strong as it once was. I called AMS today (where I bought it) and they said to check a few things. I did and they are ok EXCEPT my monitor is showing my REV is half of what my Tach is reading out (i.e. 3000 on tach = 1500-1600 on AFC) I TRIPLE checked my wiring against what AMS gave me for pin outs and against 2 other companies for pin outs on the ECU....it's all good. Settings are for 4 Cyl and the Throttle Arrow is on the up position. All other settings are correct (I believe). Any ideas????

Just incase anyone is thinking I didn't install it right, I have 13 years of experience installing electronics on cars and I tested out for ASE certification so I know I am doing it right....but yes mistakes can happen so please....don't burn me too hard!!! LOL

Also...I have the following....Forge Recirc BOV, Open Air Element Filter, and this S-AFC II (set to AMS's recomendations). That's it....for now

 

i have the same problem on my AFR, plus mines erratic... jumping around, which pin did you tap for the RPM signal?

 

You did go back and changed it to the 2 cyl, arrow up, right?

 

Yeah....sorry forgot to mention that. Feels somewhat stronger now but I still with I "knew" without having to spend $100's of dollars to dyno the car.
