Hey guys i just want a little help and advice and no rude comments or anything just because i dont really know how to tune the pfc. Ok i just installed it by myself and the car is running good and the commander reads fine with everything on the car. I set my boost to the #1 to .80 bar...that is the only thing i have set. i need help in all my other settings with the mods i have because i dont want my engine going POP! any help would be much appreciated. thanks.

 

1. Find somebody who knows how to tune the PFC well within a distance you're willing to drive.
2. Schedule a time to go see that tuner.
3. Drive to the tuner staying off boost the entire way.
4. Have your car tuned so it won't pop.
5. Go drive like heck and have a blast.

or

1. Park your car and lock up the keys until step #5
2. Buy a WO2
3. Read for a few months on the how-to of tuning a PFC
4. Tune your car
5. Go drive like heck and have a blast.

 

Is there somewhere on the net where i can read at to learn how to tune it myself or does anyone know a place in colorado springs or denver i can go to tune it?

 

Well i have a apexi power intake, downpipe, and apexi n1 exhuast...since i only have these mods dont i only have to tune certain things for these mods? please someone help! thanks!

 

Assuming the rest of your car is in "normal" operating levels (engine compression, etc) you can probably ask around and find somebody else that has a map tuned for those mods as they are very common.

Even a not-quite exact match (i.e. Blitz Open Intake, some other 3" cat-back, downpipe) should give you a pretty good start. Try to find somebody with a setup tuned for 10.5 or 11.0 AFR.

Install the map and head to your favorite dyno that has a WO2 and watch your AFR. If anything starts to look lean let off and pray Good luck.

 

When I installed my PFC I was just like you are now: intimidated by all the parameters that were available to be changed within the ECU. As you begin to understand more about basic ECU functionality, you'll realize that you can ignore many of the PFC's configuration options as a novice. The only things you really should care about right now are fuel and boost. Don't worry about timing, or injector settings, or anything else you don't understand. With only three flow mods, you're basically fine with the stock maps, and if you still have the main cat, you don't have to worry much about boost spiking and creep. You may want to add some fuel above 4000 rpm or so (5% maybe?, the procedure for this is in the Commander manual. Hint: it's on page 24).

This forum sometimes gets a bad rap, but there are some very knowledgeable people around. If you come in and ask something like "I want to add more fuel, how do I do it?" you will either get ignored or scolded to read the manual. The people that you want answering your questions respect those that try to help themselves. SO, if you come in with a post like "I'm trying to add more fuel, and in the manual it says such and so, and I found a post that says whatever, but I'm still confused" you will probably get some help.

Final tip: drive your car and monitor everything that the PFC offers. Not to be paranoid that you might blow something up, but to get used to what kinds of values are normal for your car. Think 80% injector duty is high? Don't post here. Research, then post.

Everyone should have a decent WB02 fitted to their car.eg, the Techedge one is very good and only costs the price of an intake kit.i can't beleive EVERYONE doesn't have one.

GET ONE NOW EVERYONE!!!

 

Gotta agree on the WB and I'll throw in a vote for the Datalogit and a laptop.

Once you dive in to tuning your own ride it's a great learning experience that can be enhanced by reading this forum, the other ECU forums, and the single turbo forum ... all on rx7club.com of course.

I taught myself how to tune by reading, getting a wideband o2 sensor/datalogit/laptop, and buddying up with another tech nut wanting to tune. It's lots of fun.

One thing I cannot figure out is how anyone can do a full tune in a few hours. Well, I know that it cannot be done after talking to folks that have had it done by "pros". They simply cannot tune the entire map in an afternoon. It may take days or weeks just to find and fix all the little problems with a car, then many sessions to get the WOT over a wide range of boost right, lean out cruise, get the timing right for combos of blah blah, etc etc
