can anyone tell me whether it is possible to fit an ecu from a later more powerful scooby into my 94 wrx wagon , am i right in thinking that the early wrx wagons were only 220bhp as standard. My first run on a rolling road last jan produced 202bhp with a k+n induction kit, my next run in august (i think ) with the standard air box with k+n panel filter & scoobyecu chip produced 214.5bhp which still doesn't seem that good so i'm wondering if i could fit an ecu off of say a 96wrx saloon to give me a better starting point,

any advice greatly appreciated

is it possible or not someone must know ? please

Yes, do a search for scoobyecu.

Did you not say the scooby ecu is already fitted?

How much boost does the car make?

I would be interested as I have MY95WRX, full decat and scooby ecu on standard air filter but never been on rolling road.

Mark ,
i've already had a scooby ecu fitted to my standard ecu ,What i want to do is fit a later ecu off of say a 96my car to give me more power to start with then perhaps have a scoobyecu chip fitted to that.

MAL26,
yes i've already had a scoobyecu fitted and i have boost set to 1.2bar(with a dawes device as aparently the driver circuit in my ecu is faulty and can't control the duty cycle of the boost solenoid(i think that is what i was told)and was shutting off the boost altogether) the scoobyecu is a good piece of kit it makes the car drive better and up the performance , it's just that my original ecu has a fault in it that is not related to the scoobyecu.

I thought you would get about ~30hp more with the scoobyecu rather than 12.5hp.!

Do many people have rolling road results after scoobyecu?

I the whole point of a ScoobyEcu is you are able to change the "chips" and therefore the map, these cost a few quid and then the cost of a map. I know Scot has stopped supplying these but David or Pavlo can supply them burnt with a different map(I think). I would contact them for more details.
I experimented with this and had about 3 different sets, each with a slightly different map. I could then change the map in about 5 minutes.

Hi there

hope this helps but i have a 93 wrx which should have 240bhp ecu but when i took it out to send to scott for scooby chip it was a Z4 ecu which has 260 rating from a newer subaru95/96 i think, it was running about 12.7 psi and my new chip runs the ecu at 15.5psi a works a treat. So i cant see you having any problems putting a newer ecu in

PS - any pro's out there please correct if i'm wrong!!!

Try another ECU, but make sure it's from a Wagon.
I think 1C, V5 and V9 are all wagon ECU's

If it's not from a Wagon you will hit fuel-cut due to the different spool characteristics of the TD04. Although you could tweek this with your Dawes.

Maybe your ECU has a fault that is also causing it to loose power, as I would expect a car with those modification running 1.2BAR to be well above what you've recorded.

WEBSTER

Scott,
when you did the chip for me, i was suffering problems before i had it fitted, but it highlighted the fault even more and you said there seemed like there was a problem with the driver circuit in the ecu and that it couldn't handle the new settings and kept reverting back to safety mode , this is why you suggested fitting the dawes to counter act the problem, and with this set up the car drives fine on a day to day basis .

Matt.
