I need information from someone with specific knowledge about the HKS PFC-FCON / GCC combination. I need to know if the GCC will adjust the A/F mixture 10% - 15% leaner in the 2 - 3K RPM range than my car is running right now. I have specific reasons to get my car leaned out for a short period of time.

Hey,

Can't really help you with the GCC (although I am interested in getting one to fine tune my F-CON) but would you mind posting your setting with your mods on this thread?

Ah! Trying to pass emissions I see .

Yeah, you could do that with the GCC, but probably just as easy and a LOT more flexible would be a Super-AFC. That would do the trick very easily.

If you're just trying to pass emissions, set the FCON to zero (stock fuel map) but don't romp on it on the way there and back. That should lean you out a bit.

Ya. I didn't want to mess with a full computer replace at this point. I wanted something quick that would lean this thing out a bit.
