Decided to run AT on the way back, with the extra weight and some bridges I wanted to get some of the lower RPM/higher Kpa cells. I logged this also. OK so far. Got home exported learned, saved tune but did not flash,just wanted to compare previous tune. there were some 3%-4% and one 7% VE cells, ok no prob. I looked at first log for Knock,had 0-F/R, Great. then looked at second log, the AT one, and there were about 40 knock events from 0.5-2.0 Scattered around 6k lines of data. I wondered why there would be knock in AT and not my tune, maybe the leaner AFR in AT? But thats what I was looking for, to weed out the cells that may be too advanced after adding 1* to Jamies Spark Tables. So I loaded the saved AT tune file into WinPV, checked the VE and Spark boxes,saved selected values,Opened Log Tune, loaded the .pvv file, then the .csv log file, hit calc tune and had some kind of warning/error box pop up, it said something like VE and/or other files missing or corrupt. wth, they looked ok individually,retried every step from get tune,get log from the PV, resaved them,tried again same result. I also tried it with the first log I made and it worked but said values match no changes made( of course). So should I NOT use AT log files for spark adjustment or did I screw something up? I deleted all the logs and value files, I sure dont want corrupted data.I will try again asap. Sorry I can't even make a short story short. Thanks for your patience and taking the time to help.

If you want to get a full tune in all parts of the map you need to do a few runs of an hour each. I suggest focussing on the low rpm (top rows) of the table. My bike is almost impossible to stall when taking off, and I can go wide open throttle at 1200 rpm without clunking, pinging, popping, spluttering or stalling. I regularly ride around in the sub 2000 rpm range now, whereas before it felt "uncomfortable".

Here's some tips to filling the top right corner of the table:
- use WinPV to temporarily lower your idle rpm to 900. Below 900 you risk loading oil pressure. Change it back to 950-1050 after tuning. This makes it a lot easier to tune for "standing start take off".
- "learn" the table from left to right. Don't try and tune the 1125 rpm 100% throttle square first.
- find a large empty shopping centre car park and do heaps of stop-start runs, and not accelerating until you have the clutch fully released. In first and second gear. Yes, you will get some clunking at the start and it might stall a few times but the short term pain is worth it.
- find a quiet open road and ride along in a tall gear (4th, 5th, 6th) at 1500 rpm. Open the throttle quickly to 10% and hold it there while the bike accelerates. Then repeat at 20% throttle. Then repeat at 30% throttle, etc. continue until you get to 100% throttle. The aim is to get hits in a vertical column, not a horizontal row. This makes the process much quicker.
- then repeat the whole step above but starting from 1250 rpm. Then from 1100 rpm.

Here is one of my recent tables (ve hits) after a 1 hour session. Note the hits in the top right:

I understand your learning woes. No big deal though as you play around with Log Tuner (LT) it is really pretty straight forward. You will need to save a value file for the map you are going to adjust which should be the map you data logged during your ride. You save those values by putting a check in the box next to the value you are saving and going to the "File" and save selected values. It should put it in the Value files folder you created when you installed the software. You have to name the file when you save it and I just call it "Start". Then you open Log Tuner and using it open the "start" pvv file. Then open all the logs you made while riding using your current map with Log Tuner. Create Tune and save. This puts a new pvv file in the pvv folder, which I name "end". Then exit out of Log tuner and reopen your map you were using to make the Logs and pvv files in WinPV. Go to File and "Load All Values" and select the "End.pvv" file. Then you have to save the new map you just made. I name it "whatever.LT#". In my case they are "BillyV3LT5". That stands for MeVersion3LogTuner#5. That way I can keep up with which version map and which log tuner files I used. I also save my Data Logs in separate folders in the logs folder which I name consecutively to correspond with the new map I will be making, hence folder #5 goes with LT #5. I hope that helps you out some.

Oh and LT will only pull timing out, not put timing in. So if you get the timing pulled to a point where you don't have many knock events or even no knock events, you can go back and add 1* across the board in your timing tables and start over pulling out timing with LT to drop just those cells that don't like the 1+ degree you added while leaving the ones that do like alone. I have not added any to mine as of yet and don't know if I will. My bike is running really good right now and my logs are looking really good as well. I still have some minor Knock events that I am using LT on, but I have saved my maps so if I go too far and start to lose performance I can always back up a couple of steps. I always keep one of the Maps the bike likes in slot 6 as a backup I can switch back to if need be. I try to always put the map I am currently running in slot 1. To do this you have to save the new map you create to that slot and overwrite the map that is in that slot which means if you want to keep that map for later use on the pv itself you have to first get it from the pv slot 1 with winpv, then save it back to the pv in a different slot #6 in my case if it is a good map. Then save to new map I just created using LT back to the pv slot 1. Now I can load slot 1 to the ecm and I will have the map I am going to run in slot 1.......LOL.
