Exactly, get a TC88a and George here can help you get it set up right. I used a SE ECM way back and it took a dealer to get it married to the bike. Still ran like crap because Harley has far too much early advance. With the TC88a, you can program it to do exactly what you need it to do, and no need to marry it the bike, your sister, or the garbage man.

F.W.I.W. I’ve had gremlins on both the 2004 & 2006, replaced crank sensors, map sensors swapped ICM’s and pretty much tore some hair out. Not running well but I did discover that the crank sensor harness connection under the motor, a simple two wire plug, was the root of a lot of my troubles. Irrational idle, dropping a cylinder, dropping both cylinders, got to poking around on an extended stay down in Florida found that connector, opened it up and it had a milky coating on the contacts, (why would a manufacturer put an electrical connector down in one of the filthiest places on the bike), cleaned them, a small pistol bore brush and electrical contact cleaner, slathered on some dielectric reconnected adding some shrink tube and no issues for over 20,000 miles. Until recent. Recleaned that same connector but also discovered some compromised wires in the 12 gang harness at the deutsch block connector plugging into the I C M. Just happened to bump it there and the tach dropped out, wiggled some and dropped a cylinder...WTH? Those wires were somewhat a mess, some overly long and were twisted and smushed together. Trying to resolve these I inadvertently broke one of the lock tabs inside the connector so ordered a new deutsch block, replaced 7 of the female pin terminals, shortened up a few of the overly long wires, sorted and separated the twisted and bunched up ones, plugged into the new block and have been running clean for near a thousand miles. Just saying... you may have to get intimate with your ride.
