Guest Posted December 8, 2013 Share Posted December 8, 2013 Hey GuysI am about to disconnect my ECM/ECU and replace with a new one, and I'm wondered what will be lost as a result... I heard that anything in its memory will be wiped, but what is in its memory? I have a mostly electronic dash so I am wondering if the odometer is going to reset? Or would it just be stuff like the time? (I am a bit of a novice when it comes to this)Thanks Guys Quote Link to comment Share on other sites More sharing options...

Tango Posted December 8, 2013 Share Posted December 8, 2013 Welcome to TMBF mate.....pop over to the Newbies section and introduce yourself to the gang when you can....... The ECU will hold the fuelling and ignition maps and various other info for your bike......so you'll need to know that it has the correct map loaded. If it's come off a bike that has had regular services carried out by a main dealer, then the map is probably current....whereas, if it's come off an older bike that's not been near a dealers then the map may not be the latest version..... My Speed 4 that I had a few years back was very low mileage, but only had 7k miles on the clock and was 8 years old.....and had never been serviced at a dealers in that time. When I checked the map it was an obsolete one on there......so I updated it to the latest version.....which made the bike run quite a bit better......
