need to know if i can use any ecm for a bt on my 06 fxsti
Due to differences like processor speed between later year ECM's as only one instance, you would be better off getting an ECM that is matched to your bike. There are some other differences as well.
BT= Big Twin.
and i carry it on long trips.
NO i have not I run a PC lll dyno tested and didnt want to mess things up just to experment. Its the same p/n as the bike ecm. The only reason i got it a friend got stuck a daytona (stealer) charged him $500 to replace it and for 50 bucks what could it hurt.You may be in for a big surprise when you plug it in.
Have you already tested it to see if it will handshake with your TSSM.
