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.
