Subaru mod

[xkalib3r]

Hi there,

Im hoping somebody may be able to help or maybe know someone who can.

I have a 1997 Subaru Legacy 2.0L GL Wagon. I have just installed an EJ25 engine purchased from Japan Auto Trading (One Assumes it would be a Jap Spec engine)

Motor is in, new exhaust fitted and she starts up and goes. Problem is the car is running seriously rich and guzzling fuel at a rate of knots. I suspect it would be because I am using the original ECU...

So my question is this:

A: Do you think the ECU would be causing this
B: The timing is definitely out. Could it be manually tuned or could this just be because of the ECU?
C: If it is the ECU, is there anyone who would be able to flash it with an EJ25 config? Maybe piggyback the existing ECU?


Any help would be greatly appreciated!

P.S why a wagon you ask? Well its just something different, and the car itself is scarce in SA

Which EJ25? http://en.wikipedia.org/wiki/Subaru_EJ_engine#EJ25

A) Yes, ECU is causing this, because all the parameters are targeted towards a EJ20 or variant....
B) No, you cannot manually adjust the timing.
C) You won't be able to 'flash' that ECU, not for a '97 subaru, not in SA.

You have a couple of options:
1) Aftermarket ECU, e.g. diktator (cheap'ish)
2) Piggyback system, e.g. unichip

My advice:
Fit an aftermarket ECU, your only solution bud.

Aftermarket...choose one where you have a host of settings you can alter...normally with engine swops an AFTERMARKET ECU is the ORDER OF THE DAY!

Good luck - oh, where you situated? If in CT go to GSR they are MASTERS with ECU and aftermartet ECU tuning...they even manged to slice 3.8 156 V6 with dual throttle to work perfectly...not even Dawie could manage this correctly for CT climate!

Also, if you in Jhb area, take the car to TRB for the chip changes. Scooby forum guys swear by Tim!

Hi Ponder,

From what I have found it seems to be the EJ25D, Its so hard to tell, cause Jap Auto cant give you any real details...

Hey Mr.Jax,

Thanks for the advice.

Any idea where the best place to search for such things would be?

Better a scooby nut than a scooby snack! Hoping I'll get the car into SNS one of these days

Hey CrazyFig,

When I'm that side of the world agani I'll make a turn past TRB. I gave NXGEN a call just to ask a few questions. They said they caould do it for me...For 18k for a 13 year old car, at least for now that is just a bit insane.
