R34 Apexi Pfc

[mawzy]

I've been collecting parts for the last year or so, and the last on my list was an ecu. Aiming to get a plug n play link ecu, but at 1800 + tune was gonna be a very costly endevour. So whenan apexi pfc came up cheap on TM, seemed like the better option. And from what I've read, it has a few advantages over the link, albeit some disadvantages. I havn't tried pluggin it in yet, was thinking mite try get some q's answered, and continue digging through some old threads.

It's been tuned for a neo 25det, with 530cc inj, highflow turbo, exhaust front mount pod, and fuel pump. At this stage my car is factory except exhaust, pod and frontmount. I do have 600cc inj, front face plenum, 75mm throttlebody, and at a stretch a older garret to4e. I asked about it a while ago, and the general concensus was that it'd be bit laggy for a 25det. Having trouble onselling and thinking bout maybe using it.

Now for a few q's. I have a hand controller. Not having plugd it in I don't know if it's locked or not, but am I better off going back to default tune or working with whats already on it? Can any1 help supply a near factory tune? Yes I do know the right answer is to dyno tune, but looking at the interim, to get it in running, and start putting a few parts on, but keeping the car usable. If I go back default tune, how suitable is it for driving? Ie is it a close match to a factory tune? A side not, the reason trying to get ecu in and running, I've always had trouble with my factory ecu, with r+r. I'm assuming it also keeps the vvt working? Are there any other tips people can offer to a pfc beginner?

Thanks in advance for any info, and or advice you can offer.

everything you need is in the powerfc faq in my signature

in summary

DATA INIT the Powerfc BEFORE starting the car

set injectors, airflow meter and other settings BEFORE starting the car

start the car as per powerfc self idle install procedure (in the FAQ)

the base maps are loaded when you do a DATA INIT

and will be ok to plod around and drive to a workshop

given you have non-std injectors DO NOT trash the car

plod around like a grandma, make sure you set the injectors properly and get it tuned

baby it around until you do.

powerfc retains factory VCT (skylines don't have VVT)

the t04e is dinosaur ass technololgy. don't even bother

ebay it and buy a real turbo
