I have a PFC with the factory twins and fuel system besides a fuel pump. I want a fuel map that will put me up rich enough to control that. I know the pettit and m2 ecu's have a fuel map that will control it. Basically i would like to have the same fuel map that is on those ECU's. I did search for it but couldnt find anything exact.

 

The Base mod map that comes with the PFC is good for 12psi as well as DP, HiFlow, Catback, and IC. So I would say it's plenty rich for what you have.

 

Cant you tune the PFC to handle a lot more mods than dp, highflow, catback, intake, and smic? After these mods just a fuel pump should do the trick to keep the car running smoothly right? A tunning session should allow you to tune the PFC for your setup.

 

As many of us have found, that is not necessarily true. The default PFC map leans out through the torque peak a little bit.


You can add a few % of fuel through the boost range if you want to be safe. You need to either learn how to tune yourself or hire somebody who knows what they are doing (easier said than done).

 

+1

And I would highly recommend a wideband AFR setup

 

i dont see a need for a fuel pump with ur mods.

Steve Kan is one of the best tuners out there.

 

X2. Steve tuned mine with just intakes, dp, catback, smic, and pfc. With stock pump and injectors she is good to 13 psi. On PFC high setting most seen so far is 12.6 psi (on a cool day). Seldom run more than 11 psi during summer months.

 

I think ill just sell it and get a pettit ecu, i dont want to spend all the money for tuning and getting a wideband to just run 12psi on the stock twins. If i was going to spend the money on tuning i would just wait till i had everything i needed for a single turbo setup. Since im selling the car now i think a pettit ecu will be more than satisfactory for a while considering my mods.
