Hi guys
I had hoped for a definitive yes/no answer, but perhaps not to be, IA17RGU like you I thought the warm up steps would decay as engine came up to temperature, but I do not think that is what I am seeing, don't see this as a fault but rather just the way the ecu works, I believe this may only be on 2006/7 bikes as there were some changes to ecu and iac control on 2008 and later. I did also put a call into Dynojet tech support and they were not sure either. I am hoping to set up some tests over the weekend to prove one way or the other. A bit of background why I believe the IAC warmup steps table is being used continuously even when bike is up to temp.
Bike runs great, I have one minor issue that I think I can now reproduce as required. Tickover occasionally increases to about 1200 rpm rather than its normal 1000 rpm (not a big deal but it does annoy me). When I have been cruising at about 70 mph for about 15 minutes or so pull over and tickover is at 1200 rpm, engine temp 270, iac steps 33. If I leave bike running for about 5 minutes, temp increases and iac steps drop to 30 and tickover drops to 1000 rpm and all is fine. Having discovered this is a repeatable scenario I adjusted the iac steps in the iac warmup steps table down 2 steps in the 270 degree range(from 12 down to 10). Then went out and repeated run, when I stopped tickover was 1000 rpm, engine temp 270, iac steps 31, this is what leads me to believe the iac warmup steps table is used even when bike is up to temperature. Not very scientific as many other variables could be having an influence, however I have now repeated this 4 times with the same result. For the record I did make the idiot mistake of throwing parts at a problem without truly understanding it and replaced the iac valve - £40 wasted(I should have known better). It did not resolve the issue. This has only occurred since fitting Power Vision previously had a Power Commander 3.
I will keep you posted on progress in case this is useful to anyone else

Jon
