Power Vision Information Thread
i am not a fan of the way they are displayed, would rather see everything in one line or area.... right now i have to scroll down to see more info for any given time/event.
for example, front cylinder rpm, map tps, knock etc all in one line
i know the information is all there just not organized very well (if there is a way to make excel display this way i do not know how)
Highlight the two rows that contain the Description and Unit
At the upper right click on Sort & Filter, select Filter
From here you will see a dropdown for each channel logged, click a particular channel of interest and select a range that you want to view, only that range will be displayed.
As an example if you select the Front Spark Knock Retard dropdown it will show all values logged, if it shows only 0 then you did not have any retard. If shows other than 0 then you can select those events and it will show all channels at the time those events occurred.
This link http://www.discounttire.com/dtcs/infoTireMath.dos will give you some good info on size comparisons and speed diffs.
Sorry, cant help you with the cal. values you need to use in the PV.

I reinstalled the original FuelMoto spark maps for both the front and rear cylinders. Did 4 data logs and got timing knock events out the you know what in the front cylinder. ECM pulled 2* most of the time and then added it back. One time it started at 2*, but jumped to 4* then added it back. All of this is happening in the rpm range of 2000 to 2547 and in the 60 KPA column.
So I decided to give PV log tuner a try to see what that did to my tune. Using the log tuner I imported my AFR, VE front and rear, and spark tables front and rear. I used all 4 log files from my last ride and created a new pvv. I then loaded all values from the new pvv into the current tune and saved this tune with a new name. I then did a map compare with the new tune and the original tune I ran when these log files were made just to see what changes it made. I had some minor VE changes that were less than the 5%, no change to the AFR, and very minor changes to my front cylinder spark tables with the changes being less than 1* in 9 cells with some being off by themselves. This seemed to be very little change for the timing when the ecm pulled out as much as 4* in one spot. I plan to do some new logs to see what affect that had.
I didn't think I wanted to trust the Auto tune with my timing as everyone says not too with narrow band o2's. I have to say using PV log tuner was pretty easy once you use it a couple of times and with the small changes it made I fill comfortable that it isn't going overboard with it's changes.
As I have not used PV log tuner much, can some of you who are more proficient with it from the beginning of Power Vision from it's conception give me a heads up on my method? Did I do it right or am I missing something? The only thing was it did say that the lamda reading from the wideband o2 were missing, but since I don't have them and was working on timing mostly I figured it would be OK.
My log file still showed some knock retard events on the front cylinder only. Mostly between 1800 - 2250 rpm and 59 - 64 kpa. Each time I was in 6Th gear around 16-20 TP. one event pulled out up to 7* max and another pulled out 4* max. The rest were all the usually 2* with the timing being added back quickly. I had 6 events in 140 miles of riding, all on the front cylinder. The air temperture was mid 60's. Engine temp was running between 214 and 234 with the knock events mostly near the 214 side. That is head temp, not oil.
Question 1. Could I have hit a hill and lugged it a little to get these events as I was in 6Th gear?
Question 2. How much timing retard is considered a significant knock event?
Question 3. I pulled from 1* to .5* from 1750 to 2250 rpm in the 60 kpa column, so am I taking too little timing out at that rate to do any good? I wanted to take my time and not get too aggressive with my changes.
Question 4. Should I even worry about a 2* knock event?
I reinstalled the original FuelMoto spark maps for both the front and rear cylinders. Did 4 data logs and got timing knock events out the you know what in the front cylinder. ECM pulled 2* most of the time and then added it back. One time it started at 2*, but jumped to 4* then added it back.

I made two data logs with the new map and my head temp came up and ran around 240-255 running 70 to 80 mph with a couple stop and go's. Bike seems to have a bunch more power too. Throttle response is awesome. I don't know what that did to the mpg yet as I was too busy having fun.......LOL. I should know more about that tomorrow as I plan to ride with my cuz who likes to ride more normal than my buds from this evening. I do believe it was way too rich before and I am not sure it was even running closed loop since before the upgrade I didn't have a closed loop switch. I do now and it is on so I know I am in CL now, working with the AFR table.
My logs showed only 2 minor retard events, one of which when I had the clutch in and bliped the throttle. So I think that is better too. I should get some good logs tomorrow.

The Best of Harley-Davidson for Lifelong Riders
I got in several rides today. Logs looked pretty good. I still have some minor knock events on that front cylinder, but I don't hear any pinging. I had a friend of mine that is very talented with mechanics and Harleys ride it today too. He said he didn't hear any pinging and was really surprised at how well it pulled. His take on it was, if the mpg isn't bad and no heard pinging that it should be good to go as it is tuned now. Head temps are still 240-250 out and about and 270 in stop and go........with a lot of stop for a train so they are still right where they should be. After the hammering of the test ride and my showing out a little in the first 40 miles of town riding I got 31 mpg. I hit the back roads for a total of 90 miles of mostly 55 mph riding with a strong head wind going down and tail wind coming back. That ride got me an even 40 mpg. So I think I will continue to play with the timing some, but I believe I am about done.
I love this bike!!!!!!!Again. Thanks everyone for all the help.

mess with this stuff for a while it becomes clear why someone that REALLY knows
his way around tuning a Harley is worth his weight in gold. Give the
weather 3 more months are we'll both know more about this temp stuff and
timing. I get the feeling we're both in for a hot summer, based on how
beautiful the weather is in March.
You know it will probably mean pm city when that happens don't you.
