Warm Up Stumble
« on: April 10, 2013, 12:32:47 PM »

I had my 2012 CVO Ultra tuned with the TTS last summer.  I have noticed it will now occasionally stumble like wanting to stall on warm up. Its like its starting to increase the AFR and idle speed too soon.  It does catch itself and picks up idle, not stalling, until warm up.  Still It shouldn't have the warm up stumble at all.  Question, can I take the map created by the tuner and adjust the warmup mixture and idle myself with my TTS?  Or do I need to have that tweaked by the tuner?

Add about 10 to 15% to the Warmup enrichment table from 16c to 160c and see if that doesn't smooth it out
