It should be more likely to ping with higher engine temps, not lower. Tunes actually can go bad, the o2 sensors are constantly trying to change the tune for the worse, I like to eliminate them whenever possible. Not saying that's what happened but it can and does, closed loop sucks.

Ok heres a couple pics of the plugs
Left= front/ right= rear
I went down to the shell station and put almost 3 gallons in and on the way home (only 2 miles) it didn't seem to be pinging as bad, it was quieter and seemed to need more throttle to get it to ping (over 50% for sure). Also I wanted to mention that the last few times I've started it, it's kicked back on me, hot and cold. It never did that before. I'm starting to second guess if I put 87 in it by mistake, I find it hard to believe but I guess it's possible. Really hoping I didn't screw something up in the tune when I tried to adjust the speedo cal.

Monster you're not using the TMax any more right? If you are the speedo cal won't do anything to the tune in TMax.....that being said I doubt it would do anything in another tuner program unless you made adjustments to something completely different on accident thinking it had to do with the speedo.

I'm just nervous because I'm not familiar with the tts and I may have reloaded the old map back into the ecm but I didn't see any tables or map numbers/ names when I tried to program the speedo cal but again, I'm not 100% sure. I've been talking with vdop over pm since he's very familiar with tts so I'm sure he'll get me straightened out. I'm hoping the pinging and weird starts will go away tomorrow with a fresh tank of gas from a different station. I messed with that speedo cal about 2 weeks ago and didn't notice anything til yesterday so I'm sure I'm stressing over nothing. I need to figure out how to view the map that's in the ecm right now

Weird huh? I was expecting them to look light. I'll pick up some plugs tomorrow

I've heard that there is 4 gallons go gas in the lines between the pump and the tip of the handle. If that is the case, we almost never get the premium we pay for. Only if the guy just before us happened to be pumping premium... Don't know how true that is...

Those plugs don't look bad. If you're going to do plug checks make sure it's after a good ride and the bike hasn't been restarted. Just seconds of idling could make the plugs look black and give no indication of how the bike is running in the area that it's pinging.
Narrow band O2 sensors just want lean. You'd probably see a little better fuel mileage with them but the bike will not run as good or make the power.

that would depend on if you are running AFR'S between 14.3- 14.7 in the cruise area you would benefit from the narrow band sensors taking into consideration elevations changes, fuel, etc the ecm will fine tune the VE tables to maintain those set AFR values in that closed loop area. If running outside the closed loop in cruise area just eliminate the 02 sensors .
