Hight And Pulsating Idle (MT05 EFI)

Hi,


I have Lexmoto Urban 125 clone (lj125t-16) with a Delphi MT05 that is pulsating during idle and no load conditions. I adjusted the valves which made it stop bogging down (could have been simply that disconnecting the battery fixed it), but the idle still seems too high and pulsating. I am attaching my recording that I made with HUD ECU Hacker (this thing is great!). The rpm jumps around 5:30 is me revving it a bit otherwise I left it alone.


My idle seems hight and the rev cahnges correlate with IACV Correction. Why is that?

Best regards,
Kris

The injector duration seems strange. Five is too high while 0 is too low. It should be around 2ms for idle.
