Pissedoffsol (sorry if name is wrong man) said "another vafc hack job waiting to blow up " in a post in general about a turbo civic with 311 hp.
so what is the hack? and why does it have to blow up?
The "hack" makes it possible to tune the AFC for boost application without the help of a bypassed MAP sensor, such as the use of missing link or check valve. The theory is simple. MAP input is vital for the ECU to calculate fuel efficiency. The ECU constantly compensates to changes of the power plant through various sensors. What the AFC does is allow MAP reading manipulation while assisting the ECU on fuel enrichment per RPM status.....and there it is..... the AFC "hack" in the works. Unlike a Boost Dependent FMU which only provides fuel enrichment at boost condition, the AFC actually assists the ECU on fuel management at all RPM band. It lets the ECU compensate with the changes while the AFC is maniipulating the voltage output of the MAP sensor. It hides the "actual" true reading of the MAP but still lets the ECU thinks that the input is an actual reading. The problem with this AFC 'hack" is that, it has to set the fuel enrichment lean to avoid MIL/CEL with a MAP code. I guess it can be considered a hack because it is set up so no FMU or missing link is needed.

1) how much should i look to pay for one
2) is it reccomended to install it yourself?

I wouldn't pay more than $300,I got mine from Jason for $310 shipped
But it doesn't seem that hard to hook up,just grab some patience,wire cutters,soldering gun and basic tool set,and go.A couple hours maybe.

does it monitor boost and a/f?
and can you adjust boost with it?
on a greddy 15g kit that is....
