I do know that my car is running rich now that I have installed a header, testpipe and exhaust. My questions are:
1. What's the difference in a VAFC1 and VAFC2 ?
2. What's the difference in the harness' used to install them?
3. Is this something that is permanent on the car or can it be removed once the engine is set?
4. Where can I buy everything needed?

Any other info is greatly apreciated. Thanks!

 

There are probably over 1000 threads on the VAFC topic. Let's try a search next time.

1. VAFC1 and 2 do the same thing, although 2 looks nicer, has a better display, and allows you to tune smaller rpm increments.

2. The harness let's you plug it in without soldering any wires together. Or, you can just solder them as the harnesses are expensive.

3. It isn't permanent, and 100% removeable.

4. Ebay, the FS forums here on s2ki

 

Thanks, that's kind of answer I was looking for, short and to the point.

 

 

I'd like a little more info on the harness as I am looking into doing almost exactly what the OP is, only no testpipe and I am getting a K&N intake.

I am curious about where to get the harness? I have seem VAFCs on Ebay and they say the harness is included, but the "car" end is just free wires. Is there a more complete harness that is S2000 specific? I have heard about the Frog harness.

I guess what Im saying is, give me everything you've got about the harness
