32gtr Power Fc Tuned To 12psi

[locoloc]

Hi.

I'm planning to upgrade my ecu to a power FC..Because I still have the stock ceramic turbos

I intended to tune the powerFC at 12psi still.

Having said that, do you think getting a PFC is a worth while option as far as power gains

and fuel economy.??

I thought about upgrading the turbos first but was worried that it would run rich or not run at

an optimum level without a PFC.

AND I DONT HAVE THE BUDGET TO DO BOTH AT THE SAME TIME.....

Current modifications are: Apexi Pod filters, Nismo front pipes and catback exhaust.

cheers!

yep powerfc is a good cheap upgrade, you can buy the unit new for about $1000 or 2nd hand around $900 ish

even with the stock maps its better than the std ecu and you have far more control / options with the PFC

even just adding more ign timing and using better fuel and tuning you can get some great gains/response with spending lots on a full tune

You won't get any gains worth the name out of an untuned Power FC. Your money is better spent on turbos and re-tuning the stock ECU.

im not sure what you mean but i do intend on getting my workshop to tune it

What I mean is it is not uncommon for people to plug in a power FC & run their cars on the base tune provided with the ECU.

I did for a couple of years with mine.

I would get the std computer chipped, I got mine done by Dr Drift and haven't looked back

cheapper option and a better way to go

The reason I was planning on getting the apexi power fc now is because I do intend on getting new turbos done

eventually and I guess the powerfc is like an investment for future mods...

The reason I wanted to keep it to 12psi is because i've heard bad stories on this forum about the ceramic turbos..

Or does anyone know if getting new turbos before an engine management system will be ok, as far as a/f mixtures and tune

In all honesty i'd save the cash.

The factory ECU is pretty good, get a set of cam gears put on... 12psi and it'll make 220-230rwkw and be pretty reasonable.

Mine is fine to drive around on with 1bar/GT-SS turbos on the factory ECU. Doesnt give me any grief.

Could be better obviously with a full tune even on that boost, but its not doing any harm

Better spending the cash and tune all at once.

Head down to Racepace mate, Ben knows how to get the stock ECU and cam gears going quite well in a factory style setup.

im not sure about the base powerfc map for the gtr, but with the gtst there was a huge difference. Just plugging the brand new powerfc in my bros r33 gtst was a massive step up, it started smoking second gear when before it only just broke traction coming onto boost in first.

although id always put it on the dyno and give the tune a looksie
