Advantages Of Upgrading Injectors?

Penny do you have traction control on the car???

I get this sometimes in my car as it hesitates when coming onto boost as the traction control is trying to override the throttle input.

Go see Martin Donon he is as good with subaroo as what s&j is, and you'll get good bang for buck look for willall racing in google

Are you on rexnet? They have good photo section of the website

[ontheranch]

I don't know if they have traction control?...

Yeah I joined rexnet but havnt really played around there much. SAU is homeground haha.

Where is Martin located?...

The last few days Its seemed a bit better. I changed from V power to BP Ultimate. It's strange because it doesn't do it all the time.

Slight missfire?

Mine does it sometimes to Penny, i think its just a massive overfuel situation that goes on then it takes off...Is it worse if you slowly put ur foot down or does it do it if you flatten it/ease the throttle down?

[Madaz]

modern ECU's have R&R built into them which is when they lean out they add fuel and drop timing but usually its when your boosting hard or have tried to over boost your turbo from what factory have mapped your ECU

[ontheranch]

Thanks for the info Steve, that's a bit closer then S&J I think.

I want to try a few things before forking out workshop cash on something that's pretty insignificant, that said I will want it fixed eventually.

I have only noticed it when I go to floor it and Its really brief, like talking split second only within the lag time.

[Madaz]

ah ok could be a r&r is it usually cold when it happens the weather not the car

[ontheranch]

Yeah I have only had the car a month or so and we havnt had any warm weather.

So why would R&R come in?

[Madaz]

R&R IS rich and retard when its colder your car can sometimes make more boost well this happend with my slightly modified skyline FMIC and crappy bleed valve

If your going to go to S&J you'll need your cheque book and a BIG overdraft.

They use ECU Tek Which is a complete rip (it is essentially to Subaru's what Nistune is to Nissan's) You'd bee looking at around $3000 installed and tuned and the licence belongs to you for that car. If you sell the car the next owner has to buy a licence and if you change cars and keep the ECU you also have to buy a new licence to us it in another car.

Jeff (Speedlab) does the same thing with different hardware and you be looking at under $1500 installed and tuned, and there are no licence agreements.

WRX's are a low compression high boost (14psi) engine standard and they are laggy for that, as they make all their power from boost. You could probably do with a touch more advance in ignition maps, (being low compression you can get away with more than higher compression engines) but i don't think it's worth over $1000 to get it.

Yeah it doesnt seem really worth it just to eliminate the minor hesitation. Where did you hear that the ECU Tek would be 3k? They have this deal on the webpage...

MRT Power XA Kit $2190 , includes:

MRT Full S/S Rear Muffler section

K&N Panel Filter

EcuTek Type 1

All labour

Custom fine tuning, with Dyno print-outs

They were decent priced for my service and installed my brakepads at no cost also.

Anyway I think its probably not worth spending the cash for such a small issue, I was just hoping there was a simple and easy fix but I guess not!

Thanks everyone for your imput, if I get it sorted then I shall update (or if it dissapears in the hot weather).

[D_Stirls]

That's what they charged a mate.
