BTW: what's the error when writing to the ECU?

If you're getting an incorrect voltage error, it's a common issue w/ '02 WRX's that can be compensated for by powering one of the jumpers directly off the battery. I had to come up w/ a semi-elaborate means of routing power from the dash lights through a potmeter into the jumper to get my ECU to write.

There's a ton of info on NASIOC about the issue you and your friend that's doing the update should read.
