TCFI has a BLM apply which applies the Block Learned files to the map then you reflash the ecu. I think I recall readin Tmax did not do it the same way.
Also I assume the system has a log of some sort. You should be able to look at the log and see what percent your BLM's for front and rear AFR is. Normal operating BLM is 90 to 110 percent. If is pegged at 125% it most likely is past learning also if it is around 75% same deal. 100 percent is a perfect map match, they usually have a BLM range of 75% to 125%. Hope I make sense, anyway good luck.
The Tmax is like a disabled TFCI, it just doesnt have the same potential for fine tuning that the TFCI incorperates.

Also to add:

A. Running rich in a spot or 2 is NO BIG DEAL. Many times it has to do with the poor interaction of the pipes and the cam combo. Its call REVERSION. Most people here don't know how to properly match up their intake/cam/exhaust combo. Cheap 2:1 pipes are NOTORIOUS for dips and valleys in the AFR at lower rpms due to a poorly designed "one size fits all" pipe setup. Many times not matter how much you retune or modify your map, you may still have a peak or valley in your AFR line.

B. Telling us all what your peak tq/hp numbers is useless. I want to see the dyno sheet with the fill curve. This is whats more important.

C. You adjusted your AFR to 13.5 at 768rpms? If this is the case, richen it up. At idle your bike SHOULD be running RICH. WHen your on the throttle your bike should run rich, when cruising off throttle you should be set up to lean out.

Diagnostic does not work for O2 sensors. It will always show a current fault. This part of software is not operational to diagnose O2.. To check them , link up, open the monitor function to show gauges and watch the front and rear afrs. They should calibrate to 19.36

Probably a silly question, but I'm assuming there's no way to determine your actual hp/torque numbers from the Tmax?

Nope, you still need a dyno to find out what the real numbers are.
There are ways to "guess" at it, but there are far too many external factors like the primary, tranny, belt tension, wheel bearing drag, etc. for any kind of ECM to give you anything like an accurate set of 'delivered to the ground' numbers.

Thumbs up "resetting" tMax learning curve

Hi Guys,

The simplest way to "reset" the learning curve on a T-Max is to select "Write Learned Offsets to Map". This writes what the T-Max has learned to your base map and then allows the unit to re-learn from those points up to 20% additional.

If you clear the learned offsets all you will accomplish is "re-setting" the module to the original map and will have to start the learning all over again from the beginning. In other words, you will lose all of your "learned" adjustments.

Just be sure to save the original map BEFORE you write the learned offsets so if there are any problems you can go back to the original map and start over. Acutally I would save the map and the learned offsets before writing and then save the map again under a different name after writing the learned offsets to the map.

The other option is, of course, sending your map to Zippers, letting them make any necessary adjustments, and installing the new map when thet send it back to you. This takes a little more time but the folks at Zippers have been great to me so far!

You guys that have had dyno runs and have Ur dyno sheets,

Have U posted them in the (Dyno Numbers for Softails)

It a sticky thread on the 1st page in the Softail area...Its for post and listing Ur Dyno Sheet to help other to see what different cams and builds are getting..

I AM going to have to do that sooner or later (write the offsets). Its just that I either don't have the time to pull the seat off to get at the ECM, hook up the laptop to do it or I'm too busy enjoying the bike on the road.

OK, I finally broke down (had some spare time) and tried to update my map from the learned offsets this AM.

But before I did I had to download the newest version of the software. My older version didn't have the option to "Write Learned Offsets to Map" in it.

So after setting it un on my laptop it would appear that theyt have made another change to the software.
In the latest "full" version, there is no "Write Learned Offsets to Map" option anymore. Instead they have labeled it "Learned Fuel Adjustments".
The cute part is that if you hit the "write" option it will read the "adjustments", write them to the module as an update to the installed map, then automatically rest them to '0' so the autotuner can start refining your newly updated map.

At least that's what I hope its doing. I had the laptop plugged in for over an hour with the bike "on" trying to figure things out.
So when I went to try starting the bike up all it did was buzz at me.
Seems like I killed the battery becuae I left it on too long. I should have tried doing it in the "accessories" position or at least pulled the fuse for the headlight.
Or maybe this is a sign that the battery hasn't got all that much life left in it and I should start looking around for a new one before it really does crap out on me.
God I hate pulling that damn thing out because its so tightly packed in there. Its almost like they built the damned oil tank around it instead of dropping it in afterwards.
