A quick test and look at the numbers from dyno testing a zero timed Rotax 912ULS fitted with our 4-1 EFI system.

A perfect combination.. 10% more power and smooooth running engine! Well done Thomas!

Thank you. Yes it’s a great setup

Hi, why does AFR stay way under 14,7? is it to protect the engine? max is 12,3 on the graph..thanks in advance

[@EdgePerformanceNorway]

The data you are looking at is from a dyno pull at 100% throttle. Running 14.7 at full power will blow up the engine.

@@EdgePerformanceNorway ha..ok.. thanks very much for the quick response. What is the maximum AFR you recommend? I'm going to install an AEM German wide spectrum AFR on my 912ULSFR (100CV carbs). What should I read MAXIMUM at 4000rpm in flight? 13AFR ? 13,5AFR? I intend to install an edge turbo kit in a second way..
