I just got my S-AFC the other day and I'm ready to install it. I'll dyno my car on Saturday so I can get a good setup. After my dyno, I know I'm gonna come back here and ask more questions on how to set it up against the dyno results. But for now, here are some of my questions:

1. Do I need to reset my timing because mine is about 5 deg advanced right now?

2. Anything I should watch out for when installing it?

3. Should I connect everything before the dyno or after the dyno?

I would appreciate any replies. TIA.

You should know how to splice and solder wires and be comfortable with your ecu, get the fsm and look at its diagram. I would remove the advance. Connect everything before the dyno, run it once without any settings and then tune it with your other runs.

thanks. so what is the effect of leaving the timing advanced?

I belive the Yellow wire is unused in a normal RX-7 installation. I spliced that yellow wire into the o2 sensor reading from my stock sensor. You can look at your 02 sensor voltage under "Sensor Check". I believe it is INT 3. Can anybody confirm I am right on the "yellow" wire?

is yours turbo or n/a ? what year?

you change it while on the dyno... you need a wide band o2 with you. they should have one. you do a run while looking at the wide band. you adj. then you do another run. adj, run. untill it's good. if they don't have a wide band 02. there is really no point in going. a dyno number by itself an't gona help you.

ok i got it Scott and thanks for that link too. that'll help me a lot. so should I reset my timing before I install the S-AFC? I 'm just wondering what would be the effect of this.

nothing. timming and fuel is compleaty different.

try dynoing before and after the timing change to see all your stats. Try it stock and then try advanced.
