What did you do with your Z today V (ON TOPIC DISCUSSION ONLY)

So, I ran it with what I had but since I just wanted a baseline and I didn’t want to burn through these set of tires, I was only going to run maybe a dozen laps or so, spread out into the next few hours since I have to alternate with my friends who had motorcycles.

At the same point of the track, the engine would sputter and die at WOT to accelerate out of the turn. Almost every single time, unless I let off the gas and basically coast through that section or feather the throttle at around 4K through this section.

I first suspected it was the yaw sensor which, stepped in a few times through out the day. I did look at the tachometer and saw that I was only at around 6.5k rpm when it cut off until eventually turning off. I wait a few seconds, start it again and it’s fine for the rest of the lap. Until next lap, when I get to the same area.

It’s not the engine/oil temp. I wasn’t running her hard enough and the hottest I got that day was just around 240 deg F. I thought it was yaw sensor but I was kinda going straight if not an ever so shallow turn trying to go WOT.

Fuel starvation at half tank or less from the constant right turn with some small dips?
