ban25's Track Journal

I didn't hear much besides the fact that it was not running well right at the end, as evident in the video. That section of the track, from the hairpin to cotton corners to grapevine, has three turns out of four that can trigger fuel cut even with 16 gallons, and I was getting it pretty bad at that point.

I was getting detonation, you can see the CEL flashing in the tach, which is the EcuTek knock warning.

Anyway my friend my best wishes on your engine build! i know you are going to do a great job in the engine to make sure they work a lot better

After they got a look at it in the shop, that was their diagnosis and I had independently reached the same conclusion after watching the video and replaying that moment in my mind. There's a hard fuel cut right after the hairpin, where the 911 passes me in the video. I can get this fuel cut with only 3 gallons from a full tank, so my recommendation would be to top off every session!

I've been talking with Rob at Z Car and he has some cool ideas about what we can do with the car. Will post up details soon!
