Is there any way of telling the "original 01 ECM", when removed from the bike ? Part number maybe ? I dunno :roll:
The ECM can't be reprogrammed. That is why they were replaced instead, and also why dealers did not have to send them back as dud cores. Mfg cost is probably too low to justify replacing the EPROMsStrider said:Dt, thanks for looking, I wonder now what a person would get shipped , because that is the same PN that you said HDL has listed for your bike . I wonder if Honda has just reprogrammed the old units and is keeping the same part number ?
I doubt that anybody outside of Honda really knows the complete answer to that, but I would venture a guess that there have been slight improvements to the calibrations over the years. Car models can change calibrations 7 or 8 times in one model year.Strider said:BB, I've got a few projects on the go :wink:
Larry if that's the case, I don't quite understand why all the different part numbers for all the same ECM :roll:
Looks like you're right. The updated ECM from my '03 (I put the original back in, as the replacement ECM caused the engine to stall under certain conditions) has the -305 P/N.dtredwing said:The bubble wrap sack my old unit is in with Honda's part number sticker on it has part number 38770-MCA-305 on it. I assume that is the number of the ECM Honda used to replace the recalled units.
