Alright folks, I'm stuck. Thought I could do anything, well something ain't jiving.
Got a customer who brought his bike in a CF-Moto E-charm 150 with a Dead ECU unit. These Units are in the $600 range just for the part and if it is the Regulator which fried it, can be looking at $800 just parts. Customer did not want to spend that dough on this bike so, I said lets dump the ECU and fuel injection and go to a carb/cdi set-up. Thought it would be a slam dunk, wrong----
Got everything hooked up, went with a DC cdi right off the battery, tied into the pulse trigger and I got spark, constant spark, not timed spark. So it sparks if the flywheel is moving at all, like the whole time during the intake stroke. Can't get more than a sputter or 2 out of it. Tried GY6 DC cdi, CN250 DC CDI, with stock coil, GY6 coil, CN250 coil, all combinations. Tried wiring identical to the SYM HD-200, which is the same bike just no ECU. What am I missing?
Is the pulse trigger is different for a ECU system, or is the Sym CDI got some kind of limiter in it? Don't know, going nuts. Just hate tearing into the motor to replace that trigger to find-out it is something else. Anyone deal with an constant spark situation?
Ready to give the bike back to the customer unfinished, but I really want this thing to work.
Well I am not a electrical guru BUT JR is so pm him or go to thescooterprofessor.proboards.com/ his forum has the most 250 info around and he is the most knowledgeable and can tell you what color wire goes where. Also conversions from 8 to 11 pole stator conversions which are 3 phase DC setups. He has a lot of electrical diagrams and there is a guy there that put on a EFI system and he took it off and went back to Carb. So he may also know what the problem is. Alleyoop

Yep, All the CDI's I tried work on other scoots.
I'm wondering if the pickup coil is different for the ecu version, much more sensitive and when used in normal setting it is throwing voltage from the inner magnets rotation instead of just the little bumpout magnet.
2 wire pickup coil.
Really didn't want to rip it apart gotta drain oil, coolant, boy am I feeling lazy this winter.
