Precision tuning the Rotax 912 UL/ULS

[trond]

I have solved my carburettion issues by installing LAD Aero EFI. Engine is very happy and purrs at any RPM. It idles nicely at 1500 RPM. It was a easy and clean intall and I found user support to be excellent. I went with lambda control and automatic switchover to back up fuel pump. Also changed to a Shindengen RR and warning LED and it seems to work well. Have 25 hours on the install now and could not be more happy
