HKS PFC F-CON Questions
 

I have a 88 turbo with a few minor mods.. ie straight pipe to mufflers, HKS intake, 850 cc secondaries, and an HKS F-CON. Does anybody know how to set the F-Con up for these mods. Car is running erraticly, timing is right, getting spark, air and fuel. But I think its getting too much fuel. And since the little black box is in control of that... I need to know how to set it right. There are three red sliding switches and a numbered switch from 0 to 9. What position should these things be in for the mods I got on my car? Can anybody help me? I need to get this thing running before school starts.

Try it on 3 or 4 and see what happens. When I used to have a full exhaust, intake, and FMIC I had mine at around 6. When I added the boost controller I had it at 9. That was with stock injectors.

That wont cause detonation or something bad to happen will it?

You'll have to be the judge. Good air/fuel and EGT gauges can help out. Try adjusting the knob until the bogging stops. THe 850 primaries are delivering much more fuel than you need at your current level of mods.

Got an APEX'I timer with air-fuel ratio meter on the way. Was going to replace the injectors with Venom OEM injectors. If I add an APEX'I Super AFC in place of the HKS unit... would that make it easier for me to tune my ride? This thing is really pissing me off. I really need this car for school. I dont want to have to turn to another car.... I love my 88!

You'll have to tune the SAFC to get it right. I'm sure that the 850 secondaries are causing problems.
