Default ECU software modification

As long as traction control is switched off, my tweaked VDC performs above expectations.

Sounds like a great mod!

that mod would be amazing to have. i allways thought why not making some chip like or smt for those VDC so that you could mod them to grip more or let spin wheels more etc... would be amazing.

Throttle Happy Tuning (Check their page on Facebook)

The guy who runs the business is Matt. He is based in Coffs Harbour NSW but travels around various places. He came to Brisbane for mine to be done and had several other customers waiting while I was there.

He plugged his laptop into the OBD2 port. I started the engine and he modified the ECU parameters (this took about 10 minutes) During this time I had to stop and start the engine a number of times. I then drove the car, stopping, braking and accelerating as instructed while he made more adjustments. (this took about another 10 minutes).

So its permanent changes? . Got it. And its only works on newer models i guess yes? Maybe someday someone will share how to do it or what software to use so more people could do it.

Do some searching on RomRaider. That might be able to do what you're looking for.

Romraider can acess vdc ecu and tweak it?
Would be amazing to separate TC from vdc so it wouldnt kill engine power.

It works on any ECU/TCU that isn't locked. Matt is a top engine tuner & can do this on all Subarus except the very early ones, unfortunately not my 97 Forester

CAUTION: Only use a reputable engine tuner with proven experience on your particular model and mods. Changing the tuning parameters can quickly blow the engine if not done right. The engine needs to be retuned if changes are made to the exhaust, intake, turbo, injectors, etc

Done properly, you get more usable torque with a better torque curve, better fuel economy, better reliability (ECU), no torque limiting in 1st gear, better shifting (auto) and better VDC
