Have another thread about the Walbro ecu but made a new about this problem.
Want to know if someone could share info about what pins needed to be connected when trying to communicate with Walbro ecu on bench, without bike. It is the ecu with gray & black connection and mapsensor between them. Think i have some of the connections nedded. GND = Gray C1&A8, Black A1&C8 (maybee dont need all of them, but Gray A8 is connected to several others). Gray C4 = L-line, Gray C3 = K-line, Gray C2 = TX, Gray B2 =RX. Gray B3 needs grounding when programming. What confuses me a bit is if Black A3 is "Constant" +12v and Black A2 is "Ignition" +12V. If these two connections are right or not? Could be that other connections needed also? Ecu have been interupded middle of upload of a tune and it dont have connection on bike.
Maybee there is another way to make it alive again?
