Powerfc In An Auto Stagea - Could Be Possible Soon!

[OZ_Pomy]

mmm i emailed dr drift 3 weeks ago about reprograming my ecu for a r33 cost wise ect ect im still waiting for a reply

not happy jan

[rsx84]

is there any full replacement ECU for an auto rb25det.

[satanic]

Your answer - HKS F-CON V Pro (version 3.24 + only)

Now before the critics jump up n down waving their arms around; yes it is a piggyback But, it's better than a PFC, it works on the auto on Nissans and is one of the most popular ECU systems in Japan.

And people can get these tuned where?

[satanic]

In Sydney, or you could pay to have the guy go out to where you live and tune it on a local dyno.

[Haines]

paying for the guy to come out and tune sounds really expensive

i live in Far north QLD and that in itself would be an expensive trip

let alone dyno hire costs etc

I have an r34 auto and im slowly narrowing down my options

but it seems my best bet is a dr drift tune if/when he comes up here

another option is the greddy emanage piggyback system but no one up here can tell me if it will work with the tiptronic auto (does it ???)

I should have bought a manual

[satanic]

Greddy Emanage does work; talk to 666Dan about it I think... there is a bit of DIY stuff you have to do to make it work though, something to do with the resistors?

Hopefulyl one day the HKS ECUs will become more tunable and let people from other states reap the same benefits.

I can wait - I'll just grab yours when you're finished with it Stan

Useless in SA, can only be tuned by an auithorised HKS Tuning Shop using the HKS supplied dongle and software. Which HKS charges an arm and a leg for.

cheers

was tongue in cheek - anyway, Im sure Stan would love to pay for the 1st tune as part of the "deal"

lol, quite happy with the safc/sitc combo, cheers

[DRIFTER]

how do you adjust the air/fuel ratio with an safc when the factory ecu just keeps correting it via the o2 sensor?

[satanic]

According to some "rumors" which I'm yet to justify, there are other tuners out there for HKS ECUs... whether or not this is true I don't know.

SK; why you always shuttin me down for LOL it's all good... as you said, friendly discussions never hurt anyone

[Sydneykid]

how do you adjust the air/fuel ratio with an safc when the factory ecu just keeps correting it via the o2 sensor?

The standard (slow and narrow) lambda sensor only works for constant throttle cruise and idle (generally called closed loop running). At ANY other loads (that's the other 99.9% of the time) the mapping has full control of the A/F ratios (open loop running).

thanks sk, how do i fix my lean miss at idle? what is a typical correction figure for an safc on an rb25 at say 4500rpm wot, with 10 psi, 3 ich exhaust, fmic? thanks

[Ska]

I dont think it is as easy as that..... What is the throttle position? What is the AFR? How much load is it under?

When I had my safc tuned in my r33 it took them a good hour, and 4 or 5 dyno runs to get it perfect, and it bloody did well, gained 28rwkw and ~300kms EXTRA out of a full tank of petrol, was VERY happy!!

[DRIFTER]

wot(wide open throttle)
