Also, while I don't really do autocross, my first thought on improving your times from seeing the video was to do everything earlier. In some critical corners you end up not really getting on the throttle until you're way past the apex and you've just about completely straightened out before you give it any real gas, which isn't ideal. Brake earlier and get on maintenance-level throttle through the apex to pin the rear down for more traction, and you should be able to hold more mid-corner speed and then put the power down faster as you track out.

Nice driving!
Thanks for the advice. I was really concerned about giving it too much gas and getting the rear out from under me. I need to practice throttle control for sure.

The first turn is a 360, yes. You come in wide then cut in around the center cone. The thing is that I did 7 runs and this was the only time it ever happened. I don't think that was the highest constant G run through that section. Maybe it was...maybe the other runs were just a little less? I don't know but that needs to get fixed.

Maybe it's just a question of changing fuel level? If you started out at a full tank and ran down to that 3/4 mark by this last run and then hit the starvation, then it all makes sense and it's normal. For road-course stuff I had to top off the tank dead-full before the start of each 30 minute session to avoid issues, and that's on an N/A engine. I imagine with FI you're sucking fuel out of the system a bit faster.

Talk to phunk (CJ Motorsports), they probably can do something for you. I'm not sure what he recommends for both fuel starve issues + FI, it's probably not just the standard Road Race Pump kit. Maybe that + return fuel and a bigger pump?
