The way the bike is right now is in it's factory stock configuration, that is no fueler boxes, no add on black boxes, pure stock ignition system,,ignition is triggered from the ECM,, factory map and look up tables. ?.
Hoople, Thanks for your comment.
I have a Terminal Velocity 3 installed at the moment due to the S&S 510GD cams. It has been on for the last 10,000 miles without a problem. I had switched to the Thundermax with Autotune after the problem started, thinking the TV3 had given up and to improve overall performance but I got the same, if not a bit smoother, poor performace so I eliminated the mapping as a possible cause.
All the HD tech could suggest is adding a screaming eagle map because he can't find the problem with his diagnostics machine thingy. If a fault doesn't show up, then there isn't one. I now know why they changed the job title from "Mechanic" to "Technician". Long ago a good ear and experience was enough.
