Hey guys, I have a single cam au on the dyno currently with a bf ecu running the show. Currently having issues with cylinder cut stepping in for no apparent reason. I'll post the tune and a data log shortly. Bit of information. Running the car in open loop as it's a drift car and doesn't need fuel economy haha. Have had a search but have no definitive answer.

What is the torque, fuel and spark source showing in the data log? 

If you do a DTC read with Forscan what codes do you have? 

What does the rpm signal look like if you log rpm and nothing else?

Could it be a crank trigger issue?
