Howdy,
i was wondering if anyone here knows what is necessary to modify ECU's.
I know a guy (bicariously) who does this. He made his Civic with launch control: Rev limit at 3K in 1st with clutch in, and revlimit at 8K in 1st with clutch out. Awesome...

either way i'm having some ECU trouble and need to srot it out, plus i think it would be an excellent resource.
Can anyone help me out?
Thanks
