Default Sudden drops in throttle in 3rd gear - 08-11-2020, 02:19 PM

Car is an m340 with the b58 engine. I've been noticing a weird response in throttle towards the higher RPM ranges of 3rd gear. It feels like the car just chokes for a second. It makes me let off the pedal briefly and then it will shift up and keep going. Not sure what's causing this. It did this on map3 when I was running a 95 octane mixture (of 91 and 101) and then again on map2 with a 91 octane and e25 blend (not sure what that octane would equal)

I attached the log for the map 2 run when it happened.

Looks like traction control dropping target, so expected behavior.
