I got word from corporate that battery sales are down.

Engine has to crank a couple of times to find the firing order.  Dudes 09 fired faster because it was a 96 and not something with crazy CCP from the stock 255 cams in CVOs.

Remember... there is no distributor, etc, and the crank position sensor hits TWICE in every 4 cycles.  The CPS, and the MAP sensor have to all line up before the bike throws out a spark.  The ECM looks for a big drop in map... an engine GULP so to speak... (intake valve opening at 200 rpm) followed by the CPS finding 'home'.  The other 'home' for the CPS will not be following a gulp.  See?

Older bikes used a crank position sensor coupled with a cam position sensor to find the order.

Setup:

2010 FLHXSE - no motor work
Fullsac X-Pipe and 2.0 cores
TTS MasterTune with Steve's base map - no tweaks.

Cold or warm... it takes several revolutions before the bike fires.  I am used to a carb'ed '95 inch with Mikuni HSR carb.  A twist of the throttle would fire the bike on the first compression stroke.

Anyone have any suggestions on a mod to the Map that might help?


110" motors have acr's (auto compression release). It is normal for them to spin up before firing. That is the purpose of having them. Spin up, fire plugs, save starter clutch! You are good to go.
