If I were to replace my stock rotors with lighter weight, higher compression rotors, I would need to retune my ECU. Here's the million dollar question: where can I find someone who can and will do this? I'm in the Seattle area, but the only guy I can think of probably wouldn't do it. You see, he only takes certain clients, unless the person is very rich (and I, unfortunately, am not). I very much doubt I could do-it myself either, as I have no experience with ECU programming.

 

Ooh, this is a good spot for this! Lol, I didn't even think of posting here. Thanks mod!

 

Well I don't know of any place local, sorry. But I would consider either going with an after market ecu or searching over the internet and shipping you ecu elsewhere. The aftermarket ecu would be your best option. You could also probably just use some sort of piggy back like an S-afc and be fine. Honestly I'm not even sure you would need a reprogrammed ecu, I would think the stock ecu would be fine, BUT I'm not sure and don't really know. What kind of car is it any how?
