I will agree that their customer support is pretty bad. I've tried several times now to get a simple question answered. I have a non-stock front motor sprocket (30T) installed. All I wanted to know was how to get the right value to load to make the 6th gear light work. I can't say the light matters to me but I figure if it can work, why not fix it.

Lower the Final Drive ratio in Basic settings from 87 to 86, 85, etc...I had to go to 85 on my 07 LR to get my 6th speed indicator light working again.

One thing that the auto tune products (Zippers, DTT, Terry Components) on the market cannot do is timing. Whatever timing curve your base map is set for that is what you have.

Indeed that is the BIG problem. Mine is fine in normal temps for the UK, but when temperature and altitude rise, with the TMAT, it pings like there's no tomorrow.  If only the TMAT used the ION sensor........ but, it doesn't. 

However, you're perhaps not quite correct when you say autotune products cannot do timing.  The Headquarters Pro Tuner appears to leave the timing adjustments to the stock ECM (after you've loaded a SERT Map), and then manages the AFR.  I think I'm going to try one and see how it goes.

 I have had really good results with the TMax system and autotune since I installed it over 5k miles ago. Within several hundred miles of installing the module the bike ran 100% better with no more backfiring, no hesitation in any gear, no more flatspots, better throttle response, etc. I have had some pinging issues but that was immediately resolved with better higher octane gasoline. I don't believe it was the TMax causing it but who knows. Hopefully I will not have any problems this season !!! Also, alot of people are confusing pinging with lugging and they really need to understand the obvious difference. There have been soooo many new mechanical problems (major) with the new motors (96ci and 110ci) due to the new 6 speed transmissions and people lugging the motors. I have heard this from several HD mechanics and two factory engineers.

I have the TMAT.  The AT feature did not work with my build (Zippers 120).  I had my bike tuned by a professional very familiar with the TMAX (non-AT ECM) and complimentary of its features.  Bike ran great went I took it for a test ride, however, while riding home (upstate New York to Virginia) the bike ran progressively worse until it ran almost as bad as before the tune.  When I spoke with my tuner, he advised to disable the closed loop feature and run the bike in open loop to isolate the O2 feedback to the ECM.  Once I did this (very simple fix) bike ran great again.  Since I paid for a custom tune anyway, I decided to remove the O2 sensors, plug the bungs in the pipes, tuck the TMAT wires away and run the ECM in open loop and I haven't had any issues since.  I am not an expert on these ECMs, but my recommendation to anyone having tuning issues with the TMAT is to first isolate the base map from the AT.  Run the bike in open loop, that will tell you if there is a problem with your base map.  If the bike runs fine, enable closed loop and if it starts to run poorly, at least you know the AT feature is causing the problem.  Of course, there are reasons for the AT not working properly other that the AT itself (i.e. intake/exhaust leaks, etc.) that need to be checked.

Like all technology, it evolves over time.  For those who have no problems, when did you purchase your system?  Even though my system is only a year old, I am sure upgrades/changes have been made that may have improved the operation of this feature.  I admit that I haven't paid any attention to the TMAT website since my tune because everything else works perfect.  Most of the others I know of with problems bought their systems before me.

I am open to installing any upgrades to my system that will make the AT work, but I don't see a benefit to me at this stage.  Even if it did work, I don't think I want those O2 sensor wires hanging from my pipes again, so much cleaner looking without them!

Yours apparently isn't the only similar experience Pete.  When mine was on it made wrong choices as much as right ones.  Far more instructive then my own limited experience with them however was what a gifted and experienced dyno tuner who has been friendly with the Zippers people said.  He reported the same thing.  Sometimes, in unpredictable ways, they just get it wrong.  And they can't be counted on to recover when they do.  An absolutely primary system for engine management just can't be a crap shoot.
