Matt, something is off. I run w/ TC off 90% of the time i drive the car. I have never had it turn back on me.

I have only gotten a "tc failure" only when the battery has been disconnected, and upon reconnecting/turning the car back on. Could be you have a faulty battery ?

Could it be: Car is running mostly off alternator / when not enough juice from alternator - fraction of a second no power, hence light comes on ? Wild guess.

Matt, I agree with ^, never had the TC flash back on etc.

Have you swapped out your battery yet? It only happens on track right? Wonder if the additional g's are causing a connector to come loose on some sensor

I guess you won't know if the issue is resolved with a battery replacement until Laguna

New battery is in - only happens on the track hopefully that resolves issue but want backup plan in case still on the fritz at laguna
