The only reason Sean made more power by switching to the motec was because the PowerFC didn't support 2+bar of boost. if you are planning on running 35psi by all means go an autronic or motec, but a PowerFC is perfect for a daily driven/street car

What year model is your car? Bargain to be found here... http://www.perth-wrx.com/vb/sale/32362-power-fc-controller.html

yeahh ive spotted that, only thing is i found out the hard way my rex is a conversation... chassis says gc3****** so even i dont know what year engine i have...

Thanks for clarifying jEstEr?, was never quite sure why!

Ajayjay: Post the part number of your stock ecu and i'll tell you what you have.

Jester: Every powerFC has a 3 pin header on the side of the ecu, not many people realise this is to allow you to run a 3 bar map sensor. A standard 3 bar (3 pin) Delco map sensor can be used to overcome the oem 2 bar subaru map sensor issue.....cheap fix for big boost.

Here are some of the AFM spec's for different Nissan afm's that are compatible with the FC:

80mm VG30 airflow meter can measure up to approx. 500ps (368kW)
90mm VH41 airflow meter can measure up to approx. 400ps (294kW)

So with a map sensor swap and an afm swap the numbers can be as large as your budget will allow!

Silly question, not an electric guru, where would I found the number?? Afm number??

kek GC3, she a 1.6L. GC5 fo lyfe!

3 bar map sensor = DPS 310 2000a or Denso 949940 6270
You can also use the AEM 3.5bar sensor with any powerfc.

ajayjay: look at the ecu it's self there will be a sticker on it with the brand Unisa jecs and a number like 2214-aaxxx or similar.

dont forget, 3 bar is usually including atmosphere pressure as well.

so 300 KPA = 2 bar boost.

the next sensor up is the Texus instruments 5bar.
