I've been building the car over the winter and had it out on track today for the first time. First two sessions went fine. I did forget to turn off the dsc/tsc on the first couple laps and the dash lit up like christmas tree when I hit a bumpy turn. I disabled it while on track and ecerytheve was fine after that.

Then went out on the third session and hit the brakes hard on one corner and the dash lights was flickered. Then the next lap it the engine stall mid corner for a second then comes back on, because I was still in gear (pump start). Then its did that a few more times in the session, the dash lights would dim, or the engine would die. I'm not getting any engine codes.

It sounds like you might have a weak electrical connection. Battery terminals? Grounding points?

When you say "christmas tree" which lights specifically? DSC only flashes the DSC light, normally.

Check the fuel pump. If it's a bit weak then it will starve especially in long left turns

turns out it was bad grounding. i relocated the battery in the car and painted the cross beam in the engine since it was rusted. then bolted the group wire to it but didn't clean off the paint first. i noticed when i was in the pit, when i turn the steering wheel the dash light would dim, and flicker. i knew the electric steering motor was drawing a lot of amp. also the engine look a lot longer to crank and run, but i thought that was because of the smaller battery. after fixing the ground, the engine cranks and start like it did with the OE battery

good to know, this is track is of of the few that runs counter clockwise, so more left turns than right turns.
