PowerFC plug in?

[paulR32gtr]

Are R32 GTR PowerFC's designed to plug in to your factory loom ie Unplug std. ECU, plug in PowerFC, go get tuned? Or do you need to make a new loom up?

I want to be able to revert the car back to stock easily.

[R31Nismoid]

Its a direct replacement.

Just unscrew your stocker and screw in the new one.

Nothing more to it.

It comes with a base map, so you can putt-putt it to your tuner to be porperly tuned. Dont fang around on the base map though!

thats dangerous

[WhiteR33]

I heard that even with the base map you still need some 20-40 minutes for the system to "feel" the car before you can drive it...

[paulR32gtr]

Self checks, sensors + connections or something - sounds pretty nifty. Have installed Microtech's before - which was straight forward - but this sounds like a breeze in comparison. Nice to have a car that is valued by the aftermarket parts mfrs!

Cheers

[R31Nismoid]

Yeah, nothing like a microtech with added sensors.

Will take you approx 2mins to change ECU's... hows that for piece of p|ss?

2 MINS TO PLUG IN BUT THEN 30 MINS AT IDLE! (to learn idle speed)

10 mins at idle without anything on in car

Then

10 mins on with rear de-mister

Then

10 mins at idle with a/c on in car

Well something like that.....:headspin:

hows about his:

PowerFC instlal into a R33 series 1 AUTO???

same as above?

[Guilt-Toy]

I dont think the auto will last long with a PFC on AUTO

[gatty]

you don't reckon????

we'd need to drive 350 KM's to get it tuned - if it was plug in job we'd take it there, and plug it in, then get it tuned

[paulR32gtr]

Also - does anyone know any workshops in Melbourne that have a 4wd dyno and are good with the PowerFC's ??

same as above?

Sorry don't know if it's the same for auto's...

[adznight]

Pull the old out, plug the new in. All of 5 mins work As far as aftermarket ECU's in auto's they can be a real pain in the arse, Danny (Autotrust) was looking at one for a long time but was very painfull die to the auto so he decided against.

[gatty]

so it might not go very smoothly?

[adznight]

Well put it this way, I'd do some reasearch first before the money is spent.

[gatty]

shit ay....

my mate bought it for ahis 33 - auto

the guy from autobahn has:

r32 running up to 30PSI

fully worked internals, rb26dett conversion

PowerFC (as for as i know - might be motech)

580+ rwkw

it's a triptronic auto ^^^^

tuned by sub zero in brissie - just complete.....

i mate took his advice on a PowerFC - alhthough - the guy from autobahn did think my RB25DE was same compression as the DET's so maybe he doesn't know THAT much?????

Anyone know for sure if the powerFC will be a success??

In at least 3 of those youll find powerfc and auto = jerky gear changes = it doesn't work

Hi guys, I am very interested in this thread as it is relevant to the Stagea.

 

 I have down loaded the code from an auto ecu and compared it to a manual ecu and I can tell you there is 3 times as much code in the auto ecu. These are not maps for fuel or ignition or boost, it is code to enable the engine ecu to control power (torque) on gearchanges. There is code for going uphill, down hill, flat, accelerating, decelerating, cruising, powering, turning with power steering, 4wd, abs, aircon, electrical load etc etc. All of these things affect the gearchanges and therefore have to be programmed for.

 

 This is not tuning the fuel and ignition timing and building a boost correction table.  I don't know anyone, outside of the auto manufacturers, who can do this. Plus I have yet to see an aftermarket ECU that has the capacity to handle this sort of code. This is why Apexi haven't made a Power FC for auto Skylines, they most likely don't have the expertise and would have to charge way too much for the auto PFC to make it worthwhile.

 

 So my 20 cents worth, use a piggy back to tune the fuel and maybe one for the ignition but it has to be a "simplistic" style that doesn't totally override the standard ECU timing, just moves it a few degrees. That combination works welll up to around 260 rwkw and I have yet to see a chipped standard ECU do any better. That also happens to be around my rule of thumb limit for the standard RB25 internals.

 

 There are limits to what you can map in a standard (chipped) ecu, the maps don't extend far enough, they are not calibratable, there is no ability to change correction factors (water temp, air temp, boost etc), not all maps are stand alone, they are linked and when you change one you can easily get an unwanted effect in another. They have a limit, and I have yet to see that limit exceed what can be achieved from a pair of piggy backs. So I would never count on a chipped ecu to deliver much better results

 

 If you are doing an upgrade on the internals for power in excess of that, then I strongly suggest a non electronic auto is the go. We have used Hugo's boxes in the past and they handle double that power easily. Either that or do a manual conversion, either way will be cheap compared to what you spend on the engine anyway.
