It sounds as if your computer thinks that the engine is always stone cold and never warms up after starting.
I’d make sure the sensor is screwed in snugly to the head, and that the electrical connector is clean and well secured.
Wayne,can't use GUZZI Diag (98 model)---Both sides of exhaust are black/sooty----air filter is ok---ecu set correctly (250 mv which =o)----regulator for fuel,I know nothing about,please enlighten me!!! TPS brand new(ca cycleworks) set perfect---
Like Wayne says you can't re-map it with GuzziDiag but you can see what it's doing. I would turn the idle trim back 1 turn and see if it does anything. You can always move it back, just make a note where it was.
on my '99 I wired a switch with a resistor that tells the ecu the engine is either cold in which case it gets its signal from the temp sensor or hot where it goes through the resistor. I looked up the chart and used a resistor that matched one that I think was fully warmed up. I use it like an electric choke, it wont start cold until I flip the switch. once warmed up it runs the same either way but gets better mileage if I tell the ecu its full hot.
