RS liberty piggy-back performance chips

Arrived today. Had a distinct rattle to it, opened it up and the VOS chip had come loose in transit and bent a few pins on the chip adaptor. Bent them straight and plugged it back in, no real damage ( I hope! ).

Will hopefully plug it in tonight and see what happens.

cool.

bit of a worry that the board had come lose in transit - whats going to happen with the ECU getting bounced around in your car? Cant remember exactly, but i think we glued the chip in with silicone. have a read of hte instructions available in the voschi thread on RSLC

I remember reading exactly what you suggested Dane , dob of silicone will keep it in place.

Yup, once it's in and tested it'll come back out for some sillycone.

The Vos makes a huge difference even on a lifted car with huge over gearing

Even better than VOS is an STi ecu for an early wrx. Cost about the same too if you know where to look. I have two of them and actually had one in the red ute when I used to cook the too high club around town here.

It changes the whole attitude of the car. They are more responsive out of boost and go like a cut cat when you put your foot down.

You can also look for modded STi ecus for even more response/power.

I tend to disagree, as Jap ecus do have lots of timing in for the good fuel japs get, they can be too agressive for Aussie conditions.

Pinging can kill an engine quite quickly. I'd go the VOS myself. If Adrian Vos can basically create the E8 I'm sure he did a fine job on a simple chip.

I probably wouldn't have written it if I didn't believe it so we will have to disagree on that.

Furthermore there is a hell of a lot of cars running around here with JDM STi computers and are running fine. I find it hard to believe that one person can create a better tune with limited time than a major car manufacturer spending lots of money and man hours on the project. The company that spent all that money also issued a pretty good warranty with their cars. Obviously they aren't going to be running that close to detonation from the factory that a 2 octane rating drop in fuel is going to have the engine destroying itself. They just aren't that stupid.

I have had plenty of these ecus in various cars and have not had any problems with them. As I said, I have also had modded sti computers runningfinein my own cars as well.

The old line of Japs having better fuel than us is a crock in my opinion. They get a 100 octane when we can buy 98 at most servos and 100 and selected ones.

Sure if you are stingy and only buy 91 octane fuel and try to run a JDM ecu there is going to be issues. Then again the ecu will sense knock and pull the timing and boost back if need be.

i never see any Japanese imports that come through my work changing ECU's or Tune's or basically anything because theyre coming to Australia.

although i think in Japan they limit cars horsepower to 270bhp i think it was. or around there

Thanks for the info brett, I've already got the VOS now, otherwise I'd definately look at the JDM STI ECU. In fact it would be cool to take it to a dyno with a few ECU's and dyno it on std, VOS, STI, and see what does what.

If you want to do that one day let me know and you can borrow a few of the ecus I have here.

wow what a difference!
