This is totally wired from scratch ECU is gone & new ignition circuit is totally independent of the main loom. CDI is wired properly, coil matches. Have tried multiple dc cdi's & coils . The pulse trigger is a 2 wire type. From that diagram it looks as if there is a diode involved. I tried a schottky, thinking that may be it, but didn't work. I don't know if I will have time to mess with it tomorrow. High speed switching was a good call , glad you got it figured out . John |

Should have known to look at the cf-moto diagrams, would have bought me a clue.  Real one with a gap where normally the single trigger magnet is placed.   |

Well, did the conversion ever work? I may do the same!

Yes the conversion did work, but it was alot of work and alot of new parts. To do it again would be easier, but now that MRP is gone, finding all the right parts would take more hunting.

I am new to the scooter world and currently in the same situation as I acquired an e charm 150 that has a dead ecu. I hate to invest the $600 and find out something else is also wrong, and or fry a non-returnable $600 part. Is there any parts list and step by step available for this conversion? if not could there be?

I think the equivalent of an ECU for a cheap Chinese scooter is more like $20. |

Got an oscilloscope?
You can look at the waveform being generated and go from there..
Is the pickup reading the magnet on the stator? Did you pull the cover already? Almost sounds like the system you are swapping in has a missing tooth wheel, and your CDI is firing on every tooth (this would make an almost constant spark as you describe)
Just a thought..

I did that, have the same diagrams here. It is wired properly theoretically, I am just getting constant spark. |

Hi, I'm also new here. Also have a dead ecu on a PGO g-max (blur) 220i (efi). I know about the multiple pickup points issue on the flywheel and how it enables the cdi to give constant spark.
I have two questions:
If i grind away the extra pickups on the flywheel would this work?
If i get spark using the CDI, can i keep the ecu unit to maintain the rest of the scooter? namely the fuel injectors, dashboard, etc etc? Or would i then have to change the carb to a standard carb?
Any advice would be welcome.
