Well I contacted Procom. I was instructed to set the ecu to #4. The bike now starts but wont run right. I used the map downloads, and tried different ones.They dont seem to make much difference.Lots of backfiring. I had the bike in the shop last year for this problem and after almost $400.00 they told me the prob seems to be the ecu.I didnt have them put one in because Triumph gets more that $600.00!! I am beginning to think they misdiagnosed the prob in the first place



Backfiring doesn't necessarily mean the CDI unit. It might but there are a lot of other items that should be checked first before putting out that kind of money. Have you done anything to the bike in terms of modifications? Have you checked the intake system rubbers and vacuum caps closely for cracks? Do you have your idle mixture adjustments screws set properly (turned too far in will give you backfiring)? When were the carbs balanced last? Have you checked your spark plug colour?

When does it backfire? While idling, steady running, accelerating, decelerating? Makes a difference in diagnosing.
