Sports ECU DB9 problem.

[Sedativehighs]

Okay. So I really don't know what I'm doing in regards to tuning or anything, but can somebody tell me why it is that when I fit my DB9 with a sports ECU my car becomes uncontrollable? I can barely turn corners and my car starts skidding all over the place.

Cheers.

With just the details you've provided: The ECU might add enough power that you can't control it anymore?

Slow down for the corners more, and be easier on the throttle. Maybe fit some sport mediums or softs, or turn up TCS a bit.
