It may, but the Win/PV software says .98 is the richest it will go in closed loop. I have never investigated other than that. Good to know.

jammerx, how were the spark tables in your TW555 map created? Who tuned them? They appear to be fractional #s so I assume they were created by some type of autotuning or computer tuning.

The spark tables came from a dyno tune I came across on a bike and saved it. It has been modified several times. The reason for the fractional extensions is I use the Smooth function in PV and it compares each cell to the adjacent cell and makes changes to get them linear. By the way the ECM does the same thing when you change from one rpm to the next it has many spots between for instance 2500 to 2750. If you look at some data logs you will see what I am talking about. This same basic timing map works on every setup including 10.5 to 1 and any cam except the 255. You have to come off the timing for the 255. I am running it on stock and it works fine. The 255 makes lots of compression due to its configuration.

ke5rbd, I tried the timing section of the map you supplied for a 550 mile ride today. We did a Fort Woth - Texarkana - Shreveport - Fort Worth and the timing seemed to work just fine except at one point. With engine temp at 230, in 6th at about 75, I opened up the throttle 100% to make a pass and she started pinging real bad. I backed it down until pinging stopped and made my pass. I wasn't comfortable playing with the PV while on the road so I don't have any other engine specifics. I think I'll try to retard the timing just a bit in the 3000 rpm and 60-100 KPA and see how this does.
Have you experienced any pinging in those ranges?

Can't have that pinging. Seriously I have change that map last week as I noticed it was a little jerky and not as smooth on hard acceleration. I went and looked at the map I sent and compared it to the new one and I reduced the timing in that area 6 degrees already. You can try this one if you like. It even gets better mileage and is much smoother. Had gone a little too far on timing. I didn't have any ping but I seldom try to pass at 70 in 6th, I will shift down to 5th. It will pull it but 6th is a big load at what ever speed. You can run over 100 in 5th. I only do light to moderate acceleration in 6th. You can put a 30 tooth front pulley and 139 tooth belt and it will run and accelerate hard in 6th from 50 mph up. This map should do the trick for you. It is also strategy 44 and the other was a 9 strategy. The 2012 and 13 I know used the 44 strategy. Have no idea what the difference is. When you load it it will take about twice as long the first time, so don't be alarmed.
Thanks, I'll give this one a try and see how it does. This one you just sent still shows as a strategy 9 and not as a 44.
Ya, I really don't pass in 6th either. I was just to comfortable to downshift and figured I'd give it a try.
The good thing is that I had zero problems accelerating in 6thAnother question; is there a way to copy the entire timing table to my file?

Yes, knock control is on. This doesn't stop knock, it just helps to control it.

I gave this map a try for grins. One strange thing though that I noticed is that above 2300 rpm and just cruising, the rpm will surge up and down a little. I was seeing +/- 300 rpm changes real quick. After a couple times of doing that, I pulled over and loaded back a tune that I am playing with.
I missed it on your other post about copying the timing table. Very easy. Open your file in WinPV then load Compare this file. Select compare and go to the timing table and highlite the entire timing table and do a control C, then go to the active file and select the top left cell and do a control V. Or just click the RPM in the top left of the table and it will highlite the table for you.
You may want to check the vacuum plug on top of the intake and make sure it is inplace. If it is missing it will cause the lean condition which is what you are describing. It is a black 1/4 inch plug on top side next to the air cleaner. It will also let bike ping if it is missing. You would think it would make bike idle poorly but I have seen them off and bike idled fine. The plug can get blown off if the engine ever spit back through the intake. If it is off you will chase your tail forever trying to tune for it.
