Not sure what that number is but the ecm service number is a 1226870.
I far as I know there was not any bulletin on and updated bcc for 85.

Re: Updated prom for ecm
Please excuse my ignorance on this. Does that mean it is an updated prom, and should be something I should be getting, or, is there a better suggestion?? BTW, thanks for your replies!
