Yeh I know what it does..

but leave the 2 maps thing for now.

regular SAFC just "bends" the signal from the AFM to the ECU.

AFM reads x amount of air coming through and the stock ECU maps say, x amount of air requires y amount of fuel.

SAFC jumps in between and goes "OMAGOD, bro, I swear ecu bro, der is only "z" amount of air cuming through uleh.. you gotta put less fuel in bro.."

ECU goes "Me so solly.. I put in less fuel"

and that is how you lean out the misture to make more power.

but the thing is.. on the SAFC's, you can only make adjustments against the RPM chart.

on the original blue screen SAFC, it is every 500rpm.

on the newer one I think it's every 250rpm.

so what I am trying to find out here is if the SAFC setting is static.

does it always tell the ecu to take out x amount of fuel at a particular RPM you had made a setting at?

even if you get to that RPM without boosting and therefore you have less "air" at that rpm?

Might have to start another thread..

Ok now I see what your saying and where your going with this!..

Need someone to confirm the above

I'll ask it in a new thread.

dont forget that when it bends the maf voltage to adjust fuel it also adjusts timing too...
