OT - Subaru computer reflash Options

[partwerks]

I've been told that it is possible to reflash the computer to the Subaru WRX engine.

Anyone know the protocol in doing something like that?

Sometimes on a suby turbo motor the knock sensor will pull timing from noises other than piston knock. You can build a audio device from a cheap hearing improver by removing the microphone and putting it on the end of a long wire and using a aligator clip to put it on a bolt head to actually listen to the top end of the motor while you are doing a 3rd or 4th gear pull under boost. You can hear knock before the sensor will signal the ecu to pull timing. ALWAYS check for timing being pulled on a suby when you change the tuning. And always check the oil very often as it will break down and thin out and dissappear really quick on these small capacity oil pan motors. Raising boost and tuning is easy to do, keeping the motor reliable is not as easy. Every time my son comes out to visit he seems to be looking at the logs on his laptop in the front seat of his suby to see where his motor is running. Actually he usually just runs it hard in 4th gear on a safe straight road in the country so the laptop just rides in the seat. He has been try ing to get the idle on e85 with new big injectors set so he's spent a lot of time in front of the laptop.
