Rutager, You are at the point where you need to spend actual time tuning the car. The tip-in problems you describe are where your fuel mixture is likely too lean. So, you need to program more fuel in those locations on the VE table. This is likely about 1800 rpm and above 80kPa.

Don't get discouraged. Just spend the time to tune the ECU to your particular car.
Hi Jamie,

Thanks for all your help on my car, it has really helped a lot.

The tip in was weird in that as I tried to take off from idle it bogged to below idle and yes, went lean. It did that twice, but wasn’t predictable.

You are right, I need to spend more time tuning. I also am going to reach out again to the one guy who has a dyno and who has done hundreds of MS, but never an aircooled car. I think he was too busy this summer, but maybe if I can get there before the snow flys...
