    OK here is some random data from the bike after setting the afv to 110 (from cold):
    I had to increase the TPS to 7.2% in order to get an idle of 1K+ to stop stalling.
    As the engine warmed I reduced the TPS to 6% as it was revving way too high. ADC at this point was 102. Idle was hunting between 1000-1500 regularly.
    AS the engine got towards 180C I reduced the TPS to 5.1 again to get a 1K-ish idle. Idle was hunting 1000-1300. ADC @101. Enrichment is now down to 101%.

    Sorry for the random stats. I wasn't sure what to capture initially. If you need particular data at particular times I can do the test again tomorrow.

    Oh, I also did a propane leak test, negative. Good :)

    So, in short, rchuff: it seems the afv being set to 110 helped the start a little as long as I hiked the TPS up. Do you reckon its just a tuning/learn issue now? Happy to upload maps or paste them here if someone wants to see what they currently are.

    any tps resets and afv should be done when bike is at operating temp and not cold .

    You need to wait until the Cold Enrichment is 100% before you set your idle speed.

    I appreciate the TPS should be done when the bike is warm, but if I do that I need to readjust the TPS to enable the bike to idle when cold. This is the issue I have.

    ...or have I completely fugged this up and the bike is compensating which is whats causing the issue?

    I had the same issues, ran fine when warm but would die while warming up. In ECMspy under "other maps", I think, is the cold start enrichment settings. I think there are 5 or six temperature settings and I just added fuel in the temperature ranges it was stalling out.

    How did you do that?

    Thanks for your help rchuff, I will redo the TPS and AFV at 100% enrich and report back. Expect some lovely karma if you are right ;)

    No internet or power at home as my power pole collapsed so I may be wrong, but I want to say in the other maps tab on the left side was cold start enrichment settings starting with negative something going all the way up to like 280 with percentages . I remeber at 160 or 180 is when it went to 100% colder than that it was like 104% then 107 % up to over 120%. I just added a few percent to the temperatures below where it ran at 100% so my 107% is now probably 112% or so...
