R500i Ecu / Flash
« on: August 14, 2014, 07:13:29 AM »
Hi all
I recently bought a rectifier and a R500i Ecu / Flash from a guy in south africa (cheaper than localy would you belive)

my problem is the Ecu flash dosnt look a thing like the cdi on my scooter

i told him i was looking for a new cdi unit and he said the 500ri uses this Ecu flash thing, so i went ahead and bought it
im afraid to open the plastic oem bag it comes in because i want a refund but i can tell its different ...

am i right in thinking the cdi is under the right side back fairing (as you sit on the scoot) ,, i can see it right there ,, that IS a cdi right ??

am i even right about the scoot having a cdi ?

If its an RI then no, it does not have a separate cdi, it's built into the ecu. Maybe you ordered a carb 500 cdi? What's wrong with your scooter?

Hi b&l
my scoot is VERY picky about when it will start and there dosnt seem to be any method to its madness
one day ittl start then the next it wont , i cant find any elec shorts or bad grounds
also see http://www.kymcoforum.com/index.php?topic=11952.0  thread started by HOHO , but kind of hijacked by me
anyway , i bought the rectifier and ecu flash because i was starting to run out of ideas and had the money to spend

the unit thats on the bike looks like a normal bike cdi , its right next to the rectifier ,its just this new part dosnt look anything like the original

where does the ecu fit onto the scoot ?
iv just been scouring through the service manual and cant find any mention of it

I read that whole thread. This is not a "problem" but it is a matter of starting the bike correctly. I've had customer bikes do the exact dashed thing. Do you wait 5-10 seconds after turning the key on to try cranking? This x500 has a tiny battery for how large the engine is, I've noticed this issue pop up when the battery isn't ideal. Also I'm not too sure what you mean by an ecu flash.

The strarting procedure isnt my problem honestly i start it (or try to) with the same procedure as told to me by this forum

turn key ,wait about 10 ,hit the starter   , if that fails turn key off , wait 10 ,turn key wait 10 ,hit the starter
its effing ridiculous im lucky this isnt my only transport

when it starts it will run all day on and off with no problems restarting it
