stailjim61: I followed your advice during a couple commutes this week by bumping up the timing 2* across the 30-70 KPa, then data logged, ran those through Log Tuner and applied the changes, which were all again less than 1*.

Assuming I'm happy with the map at this point, should I then remove the 2* of timing I added in addition to the timing LT already removed...or just remove the 2* from the cells that had no knock events?

Next question, since I had very few knock events, and only on the rear, do you recommend, bumping up the timing an additional 2* (total of 4*) and repeat the process?

Thanks again for all your help.

 

StailJim, I used your afr map for my trip out west. I ran several logs while on the trip, mountains, high speed interstate, loaded, and high temps. I never heard any pinging, but the logs showed some knock retard events. Mostly on the rear which is just the opposite of what happens around home or was before the heat moved in. My engine temp varied depending on condition, but ran between 256 - 270 most of the time. It did get up to 330 looking for a place to park in the bottom of Zion for 30 minutes, but cooled back to 270 on the ride back out.

My mpg was +/- .2 of the other riders with like bikes with me being consistently lower than the 110 CVO and even or up to .5 more than the 2013 RG with the same cams as mine. So I feel the fuel is pretty much right.

Looking at the logs, knock retards were a few 6* or less on the front and one 8* pull on the rear, but mostly 6* or less. There was not many of these total, but they were all interstate 70 80 mph loaded with headwind. High load riding. One such occasion happened when accelerating in 3rd gear. Also I seem to notice a lot of vibration in the bike when I got around 75 mph or above. I remember you saying something about timing causing that too.

Also I noticed the CLI was only changing when in the small closed loop area of the map. So am I right in assuming that CLI only works in CL? When it did change it was mostly 5% or less.

I ran LT on my map when I got home using those logs, but I have not run the new map yet as I don't think the timing it pulled is correct. Front cyl had 6.5* pulled in 4K @ 70,80 kpa cells 2*&3* in the 3500 cells same kpa. Rear had 4*&2* in 60,70kpa 4K rpm with 1.8* to 2.1* being pulled in the cells above those. There was smaller changes in surrounding cells as well. Plus a weird pull in 20kpa cell @3500rpm of 3.5* on the rear and 2.3* on the front. I am not sure what all that means. I am not sure I should run that map at all. Like I said, I never heard any pinging, but I don't hear well anyway.

What do you think? Try it, don't try it, mod it in the one lone cell that has a weird change to it? I just don't know where to go from here.

Thanks.

 

These numbers change when in closed loop. The way it was explained to me was to think of AFF as long term changes and CLI as short term adjustments to your fuel trims. This is how the ECM learns. Ideally the values should only change + or - 5% on a well tuned bike. These values are always changing based on the targeted value the ECM is trying to maintain. When I accelerate or decelerate the change will be outside the 5% for an instant as the ECM attempts to catch up. If for example you see 107, it means the motor needs more fuel (107%) of what was required at that specific point in time for the rpm, map, to meet the AFR/Lamda for that VE. A figure less then 100 means less fuel is required.

I probably didn't explain it correctly, but it works in my mind.

 

Check your connectors on the Front wide band. Probably not plugged in well.

 

Did all that. I have just sent e mail to Fuel Moto. Maybe the sensor has gone bad?????

Reverse the sensors...if the fault moves to the rear, you have a bad sensor.

 

I'll be installing my Autotuner and WB O2 sensors tomorrow. Is it correct to assume it will start up and run the same as with my NB O2 sensors prior to any autotuning? I just want to know if I should expect any surprises when I start it for the first time with the Autotuner and new WB O2 sensors.

 

Whats the difference in Pro Mode and how do you get to it? Do you have to be in pro mode to get the speedo adjustment?

 

Just installed a set of Wood's TW-222 cams in my 13 Limited so I am having to start all over with my tuning. I received one of fuel moto's maps for my setup and it seems to be pretty close. I have completed 6 auto tunes with the new cams and I've gotten the changes down to -0% average change and 9% max. I may do a few more logs runs. I'm trying to get the max changes down to 5 or less right?

 

Open WinPV, go to setup, then options, click on the User Level and change it to Pro.

I did my speedo adjustment by trial/error comparing my speed to a GPS unit.
