Hi guys I am working on a project and would like to see if there are any companies or members that can dump the 38770-MCA ecu? It doesn't have to be the MCA ecu specifically but any model with the 3 plugs. I need to find a tool that can extract the firmware or if there are some K-Line commands I can try.
Was there any development? If so how much success?
Thanks again

Re: MCA ECU Reflash
I remember vaguely hearing of some company that could reflash the ECU, so they must be able to read it also.

Re: MCA ECU Reflash
Although it was very hard to find. This is the place that does the reflash.

It's not what you buy, it's what you build.

Re: MCA ECU Reflash
Does anybody have just the wiring diagram of the MCA ecu? Or the diagram from the 2001 to 2005 GL1800? I need to see just the pinout page.
Thanks
Thanks

Re: MCA ECU Reflash
Thanks for those images very helpful!
So it looks like this ecu does not have a Kline pin for diagnostics with scan tool. I see the RXD-TXD pin but it does not connect to anything.
How are Troubles Codes checked on this model Goldwing? Do you jump the SCS pin to check codes?
I am asking the question above because I am looking for a scan tool that can scan the ecu with kline commands this way I can sniff the communication. The sniffed communication will help with reverse engineering the protocol and see if I can read the bin file off the ecu.
I depotted a similar 3 plug ecu like the Goldwing and was able to map out the kline circuit on the PCB so this tells me the RXD-TXD pin is indeed Kline but did Honda remove it from code and is this pin considered dead? I highly doubt it since the circuit is populated on PCB.
Back to the drawing board....
Thanks
