Thanks for the info guys, I was just worried about the bike. It runs excellent 99.9% of the time. That is the only pinging I have. I was told to use 544 for stock head pipes for my setup, just because its for heavily loaded bikes. Mine has 60 lbs of stuff plus my big a$$, plus a passenger 50% of the time. It supposed to be lower timing. I have compared it to 523, and it looks the same in the timing areas. Can someone with the advanced software look at them and compare for me? I do not have access, and I supposed to have "faith in them" according to them on the phone. Thanks again.

You'll find out that the only time you see any big timing differences in a base map is when the cams are extremely different - Most of the maps are quite similar - Pick one that is the closest match for your displacement, Cam, exhaust system and ac - and work with it from there - With the Tmax ya got to ride 20 min - shut off - ride 20 min- shut off - ride min - shut off - see the pattern. All the while working through the different RPMs - Get several hundred miles on that way and see where your at. Adjust a little and do it all again. You don't need advanced soft wear, keys or anything else to make it work in most cases - Most likly get ya in trouble if ya don't know what your doing anyways
You don't have to make it ping - if its off - it will do it all by itself with no help from anybody - just don't LUG IT

Went back to 523. Siphoned all the gas out except about half of a gallon. I rode to the store and filled it up. I had the timing down two degrees on almost all of the map. I also added 2 on the accel fuel. I rode it for about 2 hrs today and it ran excellent. I really dont know if it was just the gas or not, but it ran fine last year. I also ran the cord for the Thundermax from the module under the seat, then into the tour pack. I got it there now for easy access for later writes to module. Should I bring my timing back up to see if it was just the gas? I can honestly say have never got 2 bad tanks before. Hmmm...

If it "ran fine last year" - I would think you would reload the map that was in it last year as the starting point, unless you have changed something on the bike. As part of the ongoing upgrades to the Tmax AT - after a little bit of learning time you can write your learned fuel offset to the map and the system will start adjusting from that point. The only real tinkering that needs to be done in the home garage (other than the basic set up) is timing and that is sometimes the tricky one. Add a little see how it works. If you add and it pings take out what you added in the area it pings. You do not have to add or subtract evenly across the board - only where adjustment is needed. Whatch your tach and throttle position when identifying a problem area - that way you will know where to make adjustments - sometimes you need more timing sometimes you need less -
You might want to try your own mix i have mine something like this- AFR above 40% throttle in the 13.2 / 13.1 to 1 range. 13.4 to 1 between 1100 & 2000, 13.7 to 1 2000 to 3500 (HWY). I have my timing advanced in some areas and backed off in others from the base map. PM your email and I send a copy to ya - can't upload to post wrong file ext or something
I was having problems with the bike not performing like I felt it should for what I had done to it - ran good but at best it was about 95 hp & 95 tq - It runs better now and you know what - I'm not putting it on a dyno to find out what the actual numbers are - I like the way it runs - I know it runs better than before and Don't want to chase better dyno number - just want a good running bike for the mod and I have that now
Take your time - you will get it just the way you want it and in the process pick up a lot of saddle time - what could be better than that

I got the same line from TMax when I called about ping. Map 523 and similar symptoms to what you describe. Also, here in AZ it is over 100 degrees this time of year. I did a bit of reading here and adjusted the timing. Successfully got rid of the ping and decided to call James back and let him know. He called the timing adjustment a "band-aid" for a bad motor. He suggested map 544, but also called that a "band-aid". He said the only way to fix it properly is to tear the crank out and fix it.
I am thinking he is full of crap, but just how big a problem is crank runout? I did a search for "Tmax ping" and got tons of hits including this thread. Searched for "crank runout" and only got a couple of pertinant hits.
Bottom line is my bike is now running better than it ever has.

This WILL be the last one of their products I will buy. I love the product, but instead of finger pointing, I would have preferred help fixing it. Bike runs too well to have any problems. Thanks for the post.
