Yes, I had that same thought.

Right now, I am really limited as to the data I can collect as the local dealer recommended disconnecting the Solo 2 data logger from the car. I can reconnect the data logger to the car after the problem re-occurs with no data logger. I could then collect fuel pressure info by requesting live data (via my Foxwell scanner) and recording the results (via the Solo 2).

Great input. Thanks.

What tires are on the car, and are they different from the OEM sizes? Super sticky tires (like Hoosiers) can exceed the g-forces the traction control electronics are expecting to see, and activate the traction control. Also tire sizes that are more than 3% different in diameter to OEM sizes can do strange things to the ABS system that also sends information to the TC system.

I’m not familiar with the acronym OPF. What is OPF?

This season, I’ve run only the Dunlop Max2 Race tire and Michelin Sport Cup 2, both in OEM sizes. Both of those tire are original equipment on the 4RS to the best of my knowledge. Thanks.

If TC intervened weirdly, alignment also should be checked, especially rear axle.

Particulate filter located in your OAP (over axle pipe). It's there for ROW cars but not used in the US. Guys have chiseled out the filler inside them. Wild guess but my first thought is debris in your fuel tank that's moving around under extreme G forces causing momentary fuel issues?

Haven't experienced and not much more to add, other than I've never experienced temps above 220. Granted elevation is only 900-1k feet and temps have only been as high as mid 80s. But about 20 degrees cooler than my other car on track

No such experience since owning the car since sept -22.

What happens if you don’t come off the accelerator and just stay floored?
