Hi I have a 1996 Guzzi 1100 Sport

The ignition is switching on and off as I ride causing a backfire and the faster I go the worse it gets...Have checked for loose wires,bad earths etc..replaced ignition relay...Any help would be great..Is it a coil,ecu problem?

Have you checked the kill switch contacts? Most likely a poor contact somewhere.

Have you upgraded your relays? They are know to cause problems with these models.

Have checked the igition switch,was a wee bit of of corrosion on one wire...Have replace the ignition relay,should I replace the other two relays? Could it be the coil? Could it be a bad ground wire somewhere?

It could be anything you mentioned. Also a poor contact somewhere as well. Updating all the relays wouldn't hurt, but I don't think the others play in the ignition area.

If the bike cuts out when hot, it may be coil related. As for checking the circuits, this may help. http://forum.guzzitech.com/forum/160/30 ... 2994#p2994

As a general rule, most electrical problems can be solved by cleaning all connectors in the wire harness. Something like a TV tuner (the old contact type) contact cleaner and lubricant usually does well. Since you have already found a corroded wire, it wouldn't be a bad idea to go through everything.

Is there any diagnostic programs I can download to check ecu for faults?

You can buy VDSTS from the store tab at the top of the page. Also there is a Ducati program you can download, but you still have to purchase an interface cable. Take a look here http://forum.guzzitech.com/forum/163/6943.html

Note: I just realized you said your bike has carbs. The software I mentioned above won't help you with the ignition module, sorry.
