Hi
Installed A Scoobyecu Chip Yesterday But I Am A Bit Dissapointed
As Before The Chip Was Installed I Got 250Bhp
On The Rolling Road,Then 264Bhp When Installed
I have a Full Decat Exhaust,Group A Downpipe,Ram Airflow,Induction Kit,Running On Optimax Fuel.
I Thought I Would Get Around 30-40 Bhp
I Have A 96 WRX
Any Clues?

Have you cut the resistor mentioned? www.scoobyecu.co.uk

What size exhaust are you running?

What ECU model number is installed in it?

Sure it is a ScoobyECU?!

Hi
Exhaust Is 3.5'',Ecu Is Z4,And As For The Chip I Bought It Off Here
Off User PNB And He Said It Is A Scoobyecu.

Exhaust is 3.5"????

Think that is your problem TBH. Far too big. 3.5" from turbo back? Thats bigger than the big power Scoobs use. Or is that just the backbox?

Did you cut the resistor?

scoobypeterpump

Hi
Yes Did Cut The Right Resistor

scoobypeterpump

Yeah I Think It Is 3.5'' From The DownPipe.

Can't see it being 3.5", more likely to be 3"

Hi
The Bloke At The Garage Thinks It Could Be The Spark Plugs
As They May Need To Be Changed.

First of all, you need to realise that what is going on. The ignition map of the scooby ecu is more conservative than that of the z4 ECU. Some cars with a z4 ECU will run quite happilpy while others will det like a pig. The target boost the scoobyecu is only 2-3psi more than a standard z4 ECU. If you had a V7 ecu or something else running only 10psi then the gains would have been larger.

The other thing to check is what your actual boost is. I have fitted many scoobyecus where the car wouldn't make the target boost on the scoobyecu and didn't make the full power. This was often down to odd combinations of exhaust, but sometimes coupled with induction, or even just a week actuator.

The problem is that people think the scoobyecu is an instant fix, but to be as universal as possible it isn't too much of anything. That is why I don't bother with them any more, and people like the scoobyclinic only do them on a custom tweake basis.

Your first move should be to put a boost gauge on it of not already fitted (even just temporarily) and check the boost. It may be setup for target boost of 15.5 or around 16psi depending on it's origins. If it doesn't make targetboost, you can try shortening the actuator arm a little, or enlarging the restrictor fitted to the pipe from the boost solenoid tha goes to the inlet pipe.

HI Paul
I Have A Boost Gauge Fitted
Before The Scoobyecu Was Fitted I Was Getting 0.8Bar
Now It Is 1.0 Bar.

The power figures sound low overall, but the results don't surprise me especially. Some cars make very good power on the standard ECU, I would be interested to know the difference in torque as that can be greater than the power increase. What rollers was this on?

Paul

The Torque Was 219ft.lb Before
234ft.lb After
Had It Done At Westec Performance In South Wales

Here Are Some Pictures What My Chip Looked Like

tath

me no likee rolling roads - what does it feel like out on the road? ignoring number chasing, are you still disappointed?

scoobypeterpump

The Car Does Feel More Responsive And A Bit Quicker
Just Dissapointed at Not Getting Around 270-280 Bhp
That's Just Life.

Oh dear - so this is just a plug and go chip like a Superchip??

Been there with a company car - but for proper power on Scoobs it has to be fully mapped to suit - otherwise bit like the Prodrive chip - total waste of time

Your chip wasn't the one in the piccie. As that is one I sold to Glen in Scotland last week. Turned out his car already had one fitted..Doh!.....

I'm not sure what the origin of your chip was, but like Paul says get that actuator tightened.

If yours is one of my older ones it should be hitting at least 15.5 (1.06 Bar) or maybe even 16.5psi (1.14 Bar).

P.S The power you are getting does sound a bit low for 1 bar.
Going back a few years I had 258BHP 230ft/lb of torque from my MY94 UK. Running just under 1 Bar boost on one of my early maps. Although this didn't have any decats at the time

scoobypeterpump

Hi Scott
Yeah I Took The Pictures Off Ebay Because The Chip I Have Looks The Same
Just Wanted To Make Sure It Was A Scoobyecu.
The Stats You Give Above Are For A UK Model,I Thought Imports Would Give More Bhp?

Hi Peter
I have a MY96WRX which was completely standard apart from a nasty japanese back box when i got it,I had it serviced and set up on rolling road at power engineering and it produced 256bhp.

The mods now are a full HKS Hyper exhaust system, K&N Panel filter,dawes device,Z4 ecu with power engineering phase 2 map,16.5 PSI boost.
These mods produced 307bhp at power engineering.

I am not bothered about RR figures,but the above mods have transformed the car.
I would have thought with you should be looking for the same sort of performance from the scooby ecu and the mods you have.

Offically a ScoobyECU is one of these :
www.scoobyecu.co.uk

But 'ScoobyECU' seems to be a name used on here and the SIDC relating to anything that takes up the spare location in the 92-96 ECU.

I used to provide the ScoobyECU as above, but switched to using the Genuine 27C1028 chip and flogged them as 'SubaChip<96' from the Scoobynet Shop.

I also know Alex in Australia does the singles chip (I think he may call himself FatSports or something), and also I think Jon from Custom Scoobies uses the single chip.

The Prodrive PPP was also a single chip (running just under 1 bar), so you could have any of the above

A mate of mine even bought a car with a supposed ScoobyECU in it. It turned out to be a similar adaptor from Japan with some crappy 21psi map in it. Little use as the Map sensor only works up to about 17.5psi.

On A Dastek Dynamometers Rollers,Would It Make A Difference?
