FD owners with HKS PFC-FCON? What settings?
 

I know there aren't many F-CON users for the FD around, but maybe someone can help.
The unit comes with a dial calibrated 0-9, from stock to rich.

My mods are HKS DP, Cat-back, and RB cold air duct. The previous owner had it set on 3 with just K&N and a DP, with 0 being stock and 9 being very rich. I do occasionally get a boost spike to 14-15 in cold weather, so a boost controller is in order. But is there any rule-of-thumb setting I can use for my mods or is it just trial-and-error while the car blows black smoke? I don't have coin for an EGT or AF guage yet. Someone said there is an HKS mod reference chart somewhere at the RX-7store, but I can't find it.

Any help or suggestions?

there used to be one in the resources section of the forum, but it didnt say for this and this turn to 9.
the way i tuned mine was to make it really rich and lean it out gradually. i had one on my t2 and i could make it hesitate and sputter it was so rich, i had a "big" fuel pump in there the fcon ended up way leaner than i thought it would, with an intake hollow cats and an n1 it was on 1

pm me if you want more help

Will do. :) Too bad the adjustment knob is INSIDE the unit and sealed with 4 screws, but I guess I can leave it open on the passenger seat.
Better grab a set of plugs as well if I start out rich.

haha yeah that why mine was too rich for a long time i actually put it under the carpet...

I have the air fuel adjuster for mine but I don't know which one to go off of the screw or the adjuster knob??????????

:confused: I have the F-Con installed in mine but I dunno which is a correct setting for the FCD. I have RE-Amemiya intake, PFS downpipe, midpipe, Tanabe G-power get back. And boost spike at 4200rpm. Will a eletronic boost controller help reducing the boost spike?
Please help thank you.

Oh yea mine is a 93 base FD. with 277hp on dyno.
