I think they don’t have a high enough resolution in the engine management software/ hardware combo.
This causes the system to be too erratic to catch all the variables that affect a 2 stroke.
Hence the reason the N/A 850 for 2022 has a completely different engine management system...........
Boost is the reason for new engine management. Now they have a lot more parameters to monitor and conditions to map in ecu.
I hope they didn’t bite off too much to soon with the new boosted engine.
Crankcase injectors spraying a constant oil mix rate (percentage of fuel rate) seemed right to me; like the old CF-4.
But mapping 4 injectors on that engine was problematic also.
I don’t see the big advantage of a transfer port mounted fuel injector since it only injects fuel at that location. So now there is no fuel wash in crankcase. If so the oil would eventually clean out and engine run clean.
Since there is no gasoline wash in crankcase the oil injection rate and locations better be spot on injecting bare minimum, (like etec does) or oil will puddle and cause major tuning problems.
wasting time even thinking about fuel mapping until oiling is correct.
now you have boosted pressures..? yikes
