Stupid related question - after doing a reset adaptation in TuneECU I never got the green TPS light to come back on.
So, being that sort of person I took it off, gave it a wiggle and a poke and put it back on. Now I get a Check Engine light and the code for problems in the TPS. Can't remember exactly which. Bike still seems to ride ok.
It's already got a good tune in it from TuneECU, and I've done a long idle to let it reset.
Is there a specific procedure to reconnecting the TPS? I mean, I just screwed it back on, but do I need to be more careful about how the tabs slot together, or something similar?
And, to answer the original question - the tune you load into the ECU tables (or Triumph does), are the rough values to get the bike in a good place for the given setup, ie. the pipes, filters, etc which you're running. If you change a component, you need to change the tables. The 12-minute tune then allows the bike to fine-tune itself to learn how to behave with the new component. You'll always need both when you change something physically like the pipes, headers, filters, etc.
And no, no instructions anywhere. Took me a long time to find them originally, and I don't think they were called out as the 12-min tune, just a bullet point in a how-to saying "restart the bike, let it idle for 12 mins, done".
