I have searched for last few hours and haven't found any real answers. I installed my pfc last week and went through the idle learn and all the fun stuff. I had no issues what so ever and my car runs perfect other than some backfiring when car is at operating temp.

I have for mods: downpipe, mid pipe, cat back, trust smic, hks intakes, exedy twin carbon clutch and flywheel combo. So my question is do i have to get my car tuned on a dyno? I have read all kinds of info on doing it myself but i'm just not comfortable with doing that.

Can i just drive my car that way it is without damage anything? I'm fine with it running a little rich but people say it will run to lean on base mod map and some say it runs rich, which is it? Please some one clear this up for me!!!

 

without a wideband there is no easy answer to that question

 

The base map is OK for starting and driving the car to get it tuned. Some people have pushed their cars on the base map, which is beyond stupid if you ask me. Every car is different and needs to be tuned to it's specific characteristics. On your car the base map could be great at idle, rich in the midrange and dangerously lean in the upper rpms/boost (or less likely it could be perfect). Nobody knows until their car is tuned. You just installed a fully tuneable standalone engine management system, now you need to tune it. You have a midpipe which means you have more mods then the base map was designed to support.

 

The newer PFC base maps are pretty aggressive on the timing, I'd definitely recommend a tune.

Also, open exhaust on stock twins can lead to boost creep, I'd recommend shifting at 4000 rpm until you can get the car sorted out.

 

Alright thanks guys, at least I have an answer now. I'll install my stock ecu for now until i can get some time to tune it. Now to find someone that knows rotaries and can tune for my mods. I have read through "arghx's" post on tuning myself but it kinda freaks me out.

I have a manual with my pfc but it's all japanese. I also have a redom b type ecu that came installed in my car so i might just put that in instead of the stock one. Anyway thanks again for the replies.

 

you are way better off on the base mod map than a stk ecu with open exhaust. if you don't have a boost controller get 1 & keep it at 10 lbs or less till you get a tune. as others mentioned keep an eye out for boost creep, over 3500rpm in 3-4 gear it will start to creep up until boom. imo

 

Youre better off reinstalling a stock catalytic converter and keeping the pfc.

 

I would like to see one of these as the ones that I have seen are still the older 5.08 base mod maps which are not agressive.

 

Does all the new version PFC come with a base mod map?? Will the maps be different if I buy the PFC from different vendors?

 

Apexi puts them in when built and they are hard coded and can not be erased but can be changed.
