My 2022 ECU Part number (w/ Recall Letter);
grease monkey and my ECU part numbers (#38770-HL5-E62) are the same. Only the UPC codes are different...not sure if that matters.
However, now, we need some brave P520 owners to come forward and share some pictures and/or part #'s of their ECU's for a comparison. By comparing the part numbers of multiple P520's, of all ages, we should be able to see if there is any correlation with the ECU part numbers and perhaps even the units specifically effected by the recall notice. It is possible that all ECU part numbers are the same and it'll come down to the UPC codes? We won't know without further investigation.
I, and I'm sure many others, don't want to electively have their ECU's replaced with another unit that may potentially degrade the performance of the machine. I would like my P520 to have the same or better performance if a replacement is warranted.
