How hard is it to tune The B25 with the Apexi PFC?

[IowaRB240SX]

I already have a Nismo tuned ECU, 800cc injectors, t3/t4 turbo, Nismo adjustable FPR, and am looking at running around 14-18psi. How hard is it to tune the PFC or will the Nismo ECU do the job? I am not sure of the parameters of the ECU as it is the one that came with the motor set.

In a sadder note, I found out some bad things about the Skyline I was getting and am no longer getting it.Like, it was brought into the US in pieces.

hate to break it to you but unless its one of the *RARE* few motorex did, they were all brought into the US in pieces

and unless you have a dyno or know how to tune a car, do not touch a PFC. its something that will blow your engine if you do not know what you are doing. talk to your local tuner and see if he knows the PFC, if he does, go for it.

unless the nismo ecu was chipped for 800cc injectors (HIGHLY unlikley) it will not work.

A few guys in here in Canada with R32's, especially MINES tuned ECU's are tuned for different gas, no one has had major issues but there is a difference none the less and isn't using the full potential of the ECU. The NISMO ECU could have the same issues. I'm not sure of the software NISMO uses but it may be hard to change anything on the chip if at all.

As for running a Power FC for your RB25, I would strongly suggest it if you plan on keeping the car for a long time and plan to make some numbers. A stand-alone ECU is amazing and the Power FC will do anything you ask it to. However, if you don't know what to ask it to do, let someone else take care of that for you.
