2007 Ultra.40,000 miles. Indication of running lean. I did a auto tune back in the spring. When air temp was cooler and air was thicker.It helped. Picked up 5 more mpg. Now that the temps are 100 degrees are more. Getting indications of leanness. After I have rode awhile and engine is at operating temp . I shut it down and about 15 to 30 minutes lets say. It does not want to start.Turns over but won't start. I keep trying and finally it fires up. Plugs are burning very white. I have changed the fuel filter 8,000 miles ago. PV temp is running around 265 degrees at highway speed. Stop and go traffic it has got up to 300. I ran a compression test. Got 215 psi. Any thoughts are appreciated. Thanks. OLD 96.
215?! either the bike isn't stock or your gauge is bad. i've got a higher compression 107 and an early closing cam and mines 210. if it's really 215, it needs compression releases for hot start, it's no wonder you have trouble.

Well. As it is cranking over the compression gauge jumps between 185 psi and 215 psi. I was taking the higher number as the reading. Maybe I was wrong. Wouldn't be the first time.
It has been awhile since I did a compression check. Maybe my gauge is bad. I thought once the compression is reached the gauge stayed at peak compression.I did a test on my 95 Road King and the results were the same.
Wow. Pretty slow here. I have a question about auto tune on PV. When in auto tune mode does it stay in auto tune mode until exited? For example. If I take a leisurely ride one day and do not exit auto tune .Then do a 150 mile 85 miles per hour ride the next day. Will auto tune still be active and will read and store both rides? Thanks.
It stays in auto tune mode. However in documentation the suggested method of running auto-tunes is to get the bike warmed up, then run an auto-tune session for 20-30mins trying to hit the full rpm range, then flash the tune to the bike. Its suggested to do this 2-3 times total to try and allow the PV to learn all the sectors. Once the deltas in the sectors start to drop to very minimal differences then its considered to be complete. I know my explanation and verbiage are far from that of a pro but the Fuel Moto University website has almost everything you would like to know along with videos and how to's
My question on PV Autotune Basic with stock O2 sensors for my 2013 FLHTK Limited with Andrews 57H, no cat stock headpipe, Rineharts
free flow AC. Base PV from Fuel Moto with their loaded starter map, adjusted Min MAP to 30 kpa as suggested and ran apx 14 autotune
sessions around town, up the mountain and open highway in warm to hot temps where I live. The bike runs real well and mileage is good
also - about 38 mpg pushing it most of the time in mixed traffic. What I've never done is a 5th gear WOT autotune run and CHP be damned
I want to give it a shot. Now here's my question - I have no idea which PV memory slot I put my last and best running autotune map into.
How do I determine which PV slot my last map was downloaded into and go from there with an autotune session? Tnx in advance for
squaring me away in my old brain gone slow confusion.

A WOT auto tune run will gain you exactly nothing. At WOT the ECM doesn't read the O2 sensors so no data will be collected.

The easiest way to retrieve your tune would be to go to Program Vehicle>Load Copy>Copy of Current and this will save the tune that is in your ECM to a slot in the Tune Manager. You can then enable this tune for your tuning session. It's important to note that while in theory you can generate tune corrections at WOT with Auto Tune Basic (when you enable AT Basic it sets the entire AF table to use closed loop) however practical tuning tells us this is not optimum for several reasons; the AF mixture AT Basic uses for data collection is much leaner than normal relative to high RPM/high load operation, and also consider the corrections that are generated at WOT at this AF mixture lose accuracy when you Export Learned and the tune parameters revert back to normal from your base tune; commanded AF is considerably richer, PE fuel & timing come back into play, and the normal timing tables are put back in place.
