If you have an injector located a long way from the valve you may have difficulties getting good throttle response when using a lean steady state mixture. You could test this quite easily by making the base mixture richer with a trim and repeating the test.
Hi RossB,
I read this issue that is more like my M800.
The defferent is the injector far from the port after the throttle.
I have multi throttle syetem.
When 0~10%tps la=1, 10~100% slowly from la= 1 to .87 .
I have map the main fuel table by these LA .
No matter I set the accel parameter , it always lean spike and a little improvement.
As you say in quote, I need try to set LA richer in idle from tps 0% (I will try LA .87)
Or begin from tps 1% to set richer base fuel map.
Please provide some suggestion.
BTW, the help in MoTeC say sync position ideal value is 20~80%.
But my sync pos is 87%.
Does it work normal for accel reponse?
My injection timing is 270 ,1000 rpm.
Very appreciate.
