Hehe,



That's what I thought. Thanks Mike, any problems and I WILL post here.

you can also check the other forum. the PFC section there has a little more info.... most of the threads i've seen was how to control boost/flame thrower.



IMO, the manual isn't very descriptive, like Mike said. just read it a few times. and don't worry about the installation. it's pretty straightforward--remove stock ecu, plug in PFC ecu. then connect the commander.

What aftermarket products is the pfc preset for?

NathansRex 03-12-2003 01:33 PM

I was just wondering because i just got mine in today (thanks chuck)! and all i have on the car that is not stock is the catback, and i was wondering what else i can put on it before turning on pfc. i have these mods in my garage:



downpipe

midpipe

apexi intake

apexi intercooler

mazdaspeed alu. radiator

efini y-pipe

etc................................. https://www.nopistons.com/forums/pub...IR#>/bigok.gif





I was just wondering do i add these parts before or after adding pfc?

primarily i thought today of adding dp, midpipe, and intake then pfc.

I believe the PFC is ready for the Intake, DP, Free Flow Cat, Cat Back. The intercooler, Radiator, and even Y-pipe aren't really going to require more fuel. They are postive upgrades but not something that you are going to have to reprogram for.



As someone told me. Get a wideband on it after your install and see what your A/F ratio looks like.



Guys, other oppinions/

From APEX, the power fc is set for downpipe, intake, intercooler, and cat-back exhaust.



If you have a midpipe, you will have to enrich the map and lower the duty cycle on the boost setting to prevent boost spike.



If you have an igntion upgrade, you might have to enrich the map.



If you have a single turbo, you have to do a lot more.



It will be safer to retard the igntion timing on the ignition map after 0.5kg/cm2 boost.



0.6 kg/cm2: retard 2 degrees across the whole rpm range after 4000 rpm



0.8 kg/cm2: retard 3 degrees across the whole rpm range after 4000 rpm



1.0 kg/cm2: retard 5 degrees across the whole rpm range after 7200 rpm



1.2 kg/cm2: retard 5 degrees across the whole rpm range after 7200 rpm



1.4 kg/cm2: retard 5 degrees across the whole rpm range after 7200 rpm



Don't run more than 0.9 kg/cm2 without any tuning.

So i add these pieces then plug in pfc or can i plug in pfc first

Sorry for the ignorance i just don't want to blow a perfectly good motor.

the pfc will also work fine on a stock car, you could do the pfc first
