Power Fc

[JD-33]

Hi All,

just a quick question.. I am planning to purchase a pfc and then get it tuned after i get a FMIC.

would it be ok to get the pfc, plug it in and leave it "untuned" until i get my FMIC (prolly about 2 months down track)?

Mods I have:

turbo back 3' exhaust

hks air pod,

mbc set to 10psi

I guess the question i am asking is will it be safe to the engine to not tune it and leave it standard until i get the cooler?... will i still notice any power differences in leaving it "untuned" in the meantime? (i.e. after i plug it in)

Cheers

Can I drive around without it being tuned for a few days? Months?

You can drive the car around as you would normally but you should take care not to put stress on the engine. Basically don't fang around in it, as you could be running unsafe A/Fs etc and just causing more damaged. Best to get it tuned. Make sure you watch the knock levels if you do this to make sure there isn't excess detonation.

that pretty much sums up my question!

Has anyone else done this? and found it to be ok?

i drove mine for a whole without tuned it was fine, there is a noticable power gain and tougher feeling but it certainl does excel once its been fully tuned

was about 2 weeks i think

I hammered my car around for about 2 months before I got it tuned. Standard powerfc maps run as rich as hell so you're not going to hurt anything.

Just keep the boost below 10psi and you'll be right.

8psi standard maps - 140rwkw

13psi standard maps - 165rwkw

13psi modified maps - 209rwkw

i am running pfc with base map (no tune) and nismo 750cc injectors rofl...

been like that for like 4weeks... i get it tune one day (no damage so far )

the mafia , where did u get ur pfc tuned?? i was playing around with mine and i think my tune was reset!!! how does that happen? could it b because my battery is on its way out coz i had 2 jump start it a few mnths ago

[paulr33]

the tune is in nvram so flat battery wont erase. there are two ways to loose the tune;

1) ETC, DATA INIT, YES, Reboot car

2) incorrectly wire in ECCS relay so it's unable to save changes when power to car is turned off. this is usually happens from an engine swap install

just keep an eye on the knock meter... i've been driving mine around for 2 weeks on the base map. the powerfc base map appears to run stupidly rich, just going by the rate that it's guzzling fuel even with conservative driving!

As posted elsewhere, the R33GTS has Magic cat, Kakimoto 3" cat back, R32GTR intrcooler, 10 psi boost and a Pod filter.

The default maps in the Power FC most definitely DO NOT run stupidly rich, they are around 11 to 1 after boost build. However the ignition timing is very advanced (compared to standard). We were getting knock over 70 occasionally on Optimax (98 ron) and Ultimate (98 ron) with no difference between them, as you would expect. Filled it up with Optimax Extreme (100 ron) and knock is now zero for 99.9% of the time and we only ever seen 20 once in a month of driving everyday.

So my suggestions are to watch the knock readout and the dash flash warning. If you are getting some flashing, try Optimax Extreme (100 ron) that should fix the knock problem.

Cheers

and for the poor buggers without extreme, get some good octane boost.

Did it all myself, so I don't have to rely on the dickhead tuners in my town.

I had fuel mixtures less than 10:1 aftter 4200rpm

What sorta mods?

We haven't experienced that until we change the turbo, with the standard turbo they (about 25 so far) are always around 11's.

Correction, I did encounter one with higher than standard fuel pressure that was 10.5 ish.

cheers

Personally, I would have waited until you could afford the fmic. Get them installed at once, and go get your tune then. The money you could have saved in fuel would have been worth it.
