Reply To: Correct ECU? – GT650R 2009
So managed to work a few more bits out. It’s defo an Injection model. There’s no label/code on the loom, but its the correct one for the bike, everything plugs in OK (except ECU issue).
The original ECU is missing, I have a receipt for garage work a previous owner paid for, it was having engine trouble and the garage had reported it was the ECU. So it’s been tackled by a bodger and rather than using a GT650R or other hyosung ECU its had the original cut off (YES CUT OFF!) and then the ECU, connectors and short bit of wire grafted on from a Suzuki DL650., however most of the wires weren’t connected and I think some were wrong anyway.
The DL650 ECU is a F8T51171.
I have pinned the loom to a board, and using the wiring diagram from the Comet GT650R manual (earlier one), I have mapped out all the connections. I have identified all the cut wires at the ECU end and put them in order into choco blocks (just to hold them) and then continuity tested to make sure they are all OK from the plug to the cut end (ECU)
So I’ll need an ECU, the connectors and a bit of the loom to regraft it on, or new connectors with the pins.
I was thinking about what if I get a slightly later Delphi unit and graft that on, obviously I can ensure the correct wires goto the correct pins due to them all being cut!!
Only thing I need to investigate is the side stand sensor has been removed along with its wiring. I think rather then just bridge the two wires (Green with Red Tracer and Black with White Tracer) they have soldered the Green with Red wire to the other Green with Red Tracer wires.
