Does anybody know what the differences are between P0278.4A8 and 32564-99C apart from connector and price?
And which models each one fits ?

I fitted a temp sensor from a X1 once and it worked fine, so I assume, they are a mostly identical.

Apart from connectors they do look identical sensors as I have one of each (a man can never have too many spares when he intends the bike to stay in the family for a long long time ) .......... Harry will one day have an X1 whether he likes it or not

32564-99YB was used on X1/S3/M2/XB until it changed to P0278.4A8 in 2008 with a Dephi Weatherpack connector.

The scaling factors in the DDFI/DDFI2/DDFI3 ECMs are identical hence the output is the same.
