Hello all! I am seeing something curious with my '01 V11 Sport (IAW 15M ECU) and I doubt I am the first one to see it. Maybe someone here can shed some light on my issue. Quick rundown: I was experiencing the all too common hiccups in the machine between 2K and 3K RPM. I have already set valve lash, reset the TPS zero voltage and balance the throttle bodies. Things are MUCH better now but there is room for improvement and I want to adjust the CO trim next as the bike appears to be just a touch lean at low engine speeds. My fundamental issue is that I cannot adjust my CO trim with GuzziDiag. I either can't meet the 60 degree minimum engine temperature (more on that below) per GuzziDiag or I get a message that states "the active diagnostics module could not be started" (that quote is from memory so is not likely 100% accurate). Regarding my engine temperature: My engine temperature indication via GuzziDiag is different when the engine is running versus when it is not running. For example, if I am indicating 100 degrees C with the engine running, when I shut the engine down (as required to adjust the CO trim in Guzzi Diag) the temp indication goes to 40 degrees C. If I let it warm to 125 degrees C running, the non-running indication drops to 52. This creates a condition where I cannot simultaneously meet the minimum engine temp of 60 degrees AND have the engine not running. I think this may be the root of my trouble but I am currently out of ideas to resolve it. - I have purchased another engine oil temp sensor thinking it may be a faulty sensor with no change in behavior - I read Meinolf's comment about the sensor and I am using thermal paste in the base of my plastic sensor receiver to correct any contact issues I may have although it is pretty unlikely that would explain a different running vs non-running indication With the above temperature indication "issue" in mind, the furthest along I can get is to run the engine to get it above 60 degrees then select CO trim while running. GuzziDiag then tells me to turn the engine off which results in disconnecting communications with the ECU. After disconnecting and reconnecting communications I hit "Start" in the CO trim window and I then get the dialog "the active diagnostics module could not be started". I suspect it is because on reconnecting with the ECU GuzziDiag recognizes my engine temperature is now too low. I can't be completely sure of this though. I guess my first main question to the group is: does your engine temperature indicate differently when running versus non-running? If the answer is "no" then I may be correct about my feeling that this is my problem to solve. If you say "yes" then I need to head in another direction to correct this! Any feedback, thoughts or ideas are appreciated! Jim
