105c or so..you can change that so it kicks on sooner.
you may have a short someplace causing the poor response and the mill to flicker. The faults are stored and then after so many, the mill light comes on and then after 3 heat cycles will reset. I would start with the wires to the mill light and around the headset-- good luck!!!
Great...not really. I was hoping to find an answer to a similar thing that happened to my bike today. Went out to leave this morning after it sat idle in the garage all night, fired it up, and the MIL light was on. Ran fine, nothing weird, but it kept coming on the next few times I started it. Then, on my last fire-up to bring it home to put on the laptop, it's not on any longer...wtf? No fault codes either.
No flickering, steady as can be when it was on, then it suddenly stays off...any ideas other than the ones posted above? Thanks, all!
X-Man: Some MiL faults are transient so don't store codes.
If a monitored condition or state triggers a MIL the code will be stored.
Presumably by transient you mean the ECU will extinguish the MIL by itself (after 3 heat cycles) provided the condition no longer exists. Even then, the condition (DTC) that triggered the MIL is stored in long term memory so it can be read at a later date. Reading this thread it seems as if the MIL is flickering randomly suggesting a fault with the MIL LED itself or an earth fault or perhaps dry joint in the instrument head PCB.
Nope, sorry, disagree. The MiL does not store all faults and by transient I mean just that. A fault lights the MiL and the fault clears and the MiL goes out and no fault is stored (perhaps because there is not a code to be stored for that fault). It does not take three heat cydles to clear every MiL. That is as I understand it.
Sometimes when driving the MIL turns on and I get bad responce and a little misfiring.
Today we tried to read the fault codes with TuneECU. It connected OK (I think?). TPS changed when I gave it gas. The problem is that there were no fault codes.
My bike started doing this on the way back from Scotland, especially on a constant throttle on motorways: it would 'miss', cough the MIL would come on and within the space of less than a second it would all pass and there would be no code stored. A few weeks later it died completely - the battery died suddenly (but not unexpectedly) and it also triggered fault codes for the coils which may or may not be correct - I suspect that the dying battery failed to deliver sufficient charge to the ignition system triggering the code.
So, in summary.....look to your battery first, then the coils which are maybe breaking down sporadically under prolonged constant load.
