anybody running this? any tips or tricks? im about to pick one up for 150 bucks. got full exhaust w/ highflow cat, cone intake, no emissions on stock s4 turbo. should i keep stock injectors or upgrade to say...some 720 secondaries. got a s5 turbo/manifold on the way which i might do a compressor side upgrade. any help with from anybody with experiance with the f-con would be highly appreciated.

What i know is you have to plug in the fcon, and it will work. Any more tunning required, you need a GCC and a VPC. F-Con itself will attain all fuel curve from the stock ECU and adjust to the required fuel the motor required.

i can't remember clearly, but i believe that you need to tell the FCON what injectors your using and how much percent u want to run them to, there are dials in the back of the FCON, i believe and you suppose to move them around.

number on the injector dial means how rich 1 normal 9 very rich or someshort, if you don't have a manual it's going to be a problem unless someone can send u a diagram to tell you how to change the injector duration.

The fcon should come with a base program for stock injectors. At most authorized hks dealers they should have the equipment to change its settings. If they dont, pick up a GCC its like 100 bucks.

The dial on the fcon is to change the fuel aggressiveness, not the size of the injectors. I suggest getting on a dyno or the like and seeing which setting works best for your car and your mods. The FCD it has should also have a similar dial, leave it on 2.

do you think a f-con w/ GCC is a better set up than a S-afc? or vice versa? why?

I have an F-con on my 87TII
MODS: full HKS exhaust (single) w/ res and no cat
Bonez intake, 2 MSD sci boxes, Accel 8.5 wires, pulleys, no air pump, S-15 BOV, and Walbro 255 fuel pump. I just hit the dyno for 305whp. Don't change the injectors, just make sure they are clean. Just plugg in the f-con and go fast. If you need the factory instructions, just email me at aaronandmarie@msn.com. There is no tuning involved. It does all the work for you. If it's not broke, don't fix it. Just make sure the little green light comes on the unit.

I think the fcon is better than a s-afc. It bases its fuel map on boost, and not pre programmed on a dyno like a safc. Weather conditions change, boost creeps. The biggest problem w/ ecu is it limits the DC to 65%. The fcon removes this, allows you to make a lot more power on the stock injectors.

however if you have an upgraded turbo you should invest in the gcc or get rid of the f-con and go haltech or something comparable.

hey guys i jsut got my fcon and im ready to hook her up, do you think ill be save, a/f wise if i put in my stock injectors and get rid of my safc, i have a full 3 in exhuast, intake, tb mod, stock j spec ic , and i have a manual boost controller set at 10 psi but i see soem spike to about 14, i also have a walbro fp.

The F-CON doesn't work well with larger fuel injectors.

I CANNOT believe an FC with stock turbo and stock fuel injectors can hit 305rwhp, unless that dyno is super screwed.
