I have been having this issue under heavy load and I finally caught it on the datalog. Normally it is more of a jerking sensation under high load, however I did not catch it on the datalog. When I tried I caught this:



at t=2068.5

Here is the the datalog .msl

I don't really know how to troubleshoot this. Could it be the CAS?

Good call brain. I forgot that I had enabled that a while a go before my fuel map was tuned. Sure enough that is what it appears to be. The other times it happened today were also under high boost situations.

I had it set for 200kpa
