My car has the mods listed in my sig. Basicly I'm hitting 12 psi on the stock ecu. I posted a bunch of threads on remapped ecus now im just wondering if i should go the extra mile and get the pfc.

Lets say I want to run 14psi, even if I'm only hitting 12psi now with intake and dp. Get the car tuned for (?what?)psi and use a boost controller for lo and hi boost settings?

Of course Im going to want to throw on a CB which will up boost. Do I have to get the pfc retuned? Or can this be compenstated for ahead of time?

To keep the car running at its optimum evertime a mod is added the pfc needs to be retuned?

I'm by no means one of the more knowledgeable ppl on this forum, but I can tell ya some basics I learned along the way:

- 12 psi is pretty much the most you can/should go w/ a stock ecu. So bottom line: engine management is a must if you're gonna go any further than that

- you're concerned with having to retune the PFC every time you add a mod. for the most part, this applies moreso to flashed ecus, which are pretty static (requiring them to be reflashed every time you upgrade), vs. the PFC.

As long as it isn't a MAJOR modification, the PFC should be able to recognize minor mods (intake, exhaust, etc) and adjust appropriately. Now that doesn't negate the necessity to properly tune it, esp for higher boost

- once you start upping the boost, you're getting into an area where you'll constantly needing to ensure you're getting a proper air/fuel mixture. so in that sense, retuning is inevitable, no matter what EM route you take.

- if you ask me, I'd get the PFC w/o even thinking twice over any flashed ECU. Why limit your potential from the start? Sure, maybe today you only want 12 or 14 psi. But you never know how far you'll want to go in the future. There's no point in having to incur further costs in throwing away that ecu and getting a real fully expandable and programmable ecu like the PFC. So I think it's a no-brainer.

I hope that helps some (and I hope everything I said was accurate lol)

EDIT: oh ya, and if you know someone with a dataloggit for the PFC, you can literally load maps right onto the PFC. No need to go in and manually retune w/ the commander, which is a pain (and complex if you ask me).

Not recommending this, but in the sense of compensating ahead of time, you can tune your PFC to include the CB before you put it on, and in the meantime you'll be running a little rich. But to answer you're question, it is possible.

This is false. The PFC does not recognize ANY modifications. The PFC isn't a TEC III that can tune itself with the push of a button. The tuner is the person sitting behind the laptop plugging in numbers with the datalogit....which also happens to be the person who recognizes modifications..

Power FC/datalogit/wideband is a POWERFUL tool in the right hands. Tuning fuel is cake. X a/f means you add Y percentage of fuel on the fuel map multiplied by the base map for N / P block and you have how many milliseconds the injector opens up at a certain rpm and boost level. If you need more fuel, then turn the percentage up. Too rich? Lower the fuel a percent(or 3) at a time.

Lemme tell you why I said that, and lemme know if I'm still wrong

I was told that the PFC can detect changes in airflow...for example if you get a better intake or free up your exhaust some, it can detect a change in the air/fuel mixture, and can "self-learn" that, much like it self-learns the idle when you first install it...true?

You were told wrong.
