Sister of Muffin continues to exceed expectations, but one thing I have noticed that is spoiling to enjoyment is idle...
I have been finding that if I want the bike to idle nicely at 1050RPM when cold, whilst I put my crash helmet and gloves on - a bit like Freddy here
at 1:00 - I end up with the bike idling at 1300-1400RPM when it's warm. And add to that, a slow decel from 2000RPM to the 1300RPM... Grrr...
And I don't appear to be alone, after asking the question to a handful of other X1 owners, they suffer from the same annoyance (although they appear to be more forgiving than me)
SoM is fitted with Race headers and muffler and a Forcewinder, but there has been a minor apology, I have been running with a standard ECM. Not such a big apology as the bits of the map that matter are common between two. And although I was very happy with the static timing, I thought I would do another TPS reset. The difference was 0.02V which is an error of 1 TPS value on the map. Obviously not helping, but I am sure not noticeable...
After the TPS reset, I also loaded the Race maps.
I still haven't ridden it since as the weather is more favourable to windmills than motorbikes, however I am already planning potential fixes...
There are a couple of options:
1. Play with the Warm Up Enrichment table - not preferred as it affects the whole map
2. Play with the Idle Spark Advance Table - I do this on my XBs to have a crisper idle and pickup
3. Play with the Idle Correction - this is a factor on idle fueling and has no effect on an XB as they have a Closed Loop Idle control
4. Invoke the Closed Loop Idle control and do 2.
The Warm Up Enrichment table looks like this:
This factor is applied to the whole map in response to the measured engine temperature.
The Idle Correction table looks like this:
This factor is applied to the idle area (below 1350RPM and below 27 TPS) in response to the measured engine temperature.
The Idle Spark Advance looks like this:
This advance is added to the ignition timing map in response to the measured engine temperature.
So, plenty to play with. My money is on the Idle Spark Advance to give me a good result, 20 degrees (plus the 5 degrees advance on the base map) seems a bit much at 10 deg C.
First, I need to get the bike ticking over nicely when hot as I have since changed the tickover screw setting when doing the TPS reset... Hopefully I can do that on Saturday...
