Hight And Pulsating Idle (MT05 EFI)

krisztian_andre · 05-13-2024, 09:53 AM

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,

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