I am currently running a PC III with O2 senors eliminated. My tuner did in fact do an excellent job and the bike is running great. From Canada down to Vegas and back it ran with no issues. I am now wanting to change a few "minor" things and do not want to re-tune each time.

Does anyone have an oppinion on changing to the T-Max? Is it worth it? Does it work just as good as an excellent tuner or would I be better off to stay with the PC III?

It's a crap shoot.  Assuming the ECM's initial tune is actually very good for the bike (and this is a big assumption as the supplied library is not at all bulletproof) some have had quite good luck with the "auto" part of the autotune.  Some, however, have not.  It seems to get it wrong sometimes. 

This isn't just in my own experience.  A couple of very busy and skilled dyno tuners have reported the same experience to me in our conversations.  It might, or might not, be a crap shoot. Unfortunately you just never know until it's too late.

I really appreciate the response. I too have heard mixed reviews but still not convinced which way to go. The T-Max makes many claims regarding cooler temperatures and "almost perfect" adjustments while riding based on conditions.

I am leaning towards doing most of my mod's before spring and then getting it tuned again for $200.00. It's a hell of alot cheaper in the end I suppose?

I have the TMAT and while I am very satisfied with the ECM performance, the AT feature does not work, so I run it in open loop only and removed O2 sensors and plugged pipes.  For $200, have it re-tuned.

A big "if" to keep in mind.  If you've got a tuner close by who can dial it in the first time.

If that's the case the odds are more in your favor.  The autotune might or might not keep up with changes you make later.  If they're very dramatic it likely won't actually.  One relative certainty, however, is to not assume effective assistance dialing it in from Zippers.  Support is not their best thing.  Unfortunately all too often anymore it seem to not be any kind of thing at all with them.

The TMax ECM has some real promise.  As poorly as the company treated me and as poor was the machine work they supplied I can't knock the potential of the ECM.  But it is potential that has to be dialed in elsewhere unless you are very luck and score with a caned map.  And it's potential that is a real crap shoot where the autotune adjunct is concerned.

Personally, barring a good local tuner familiar with the ECM to dial it in the first time I'd not give it a second try.  But I've already learned my lessons with it the hard way.

If you like to tinker with it yourself another option is to get a Twin-Scan II+ unit from DTT. Install the unit, log data, and it will tell you where to make adjustments to your map. Works with a PCIII as well as the Race Tuner. I have tuned bikes this way it they get really close. The top end full throttle runs are hard to get enough data on (unless you have a drag strip availible) but the everyday riding areas can get tuned in very well with this.

For the Auto tune ECM's I have had great results with the Daytona TCFI unit. It is a bit of work to get them set up but once they are going they work very well.

Great .. more options I'm really stuggling on what to go with. All are a fair buck amd I want to try and be assured I will be happy and it will work great with my bike.

I have T-Max with Autotune on my 07 SE Ultra . Put it on last April and ran good with the mods that I have done(cams, heads, & D&D 2into 1,s) Seemed to run hot in the summer. Zipper's played with it while I was at Biketoberfest
in the fall. Ran perfect after that. No complaints. I have had 2 PC111's fail on my last bike which were replaced under warranty but it was still apita.

I'll also vouch for the Twin Scan II+. I like to tinker with the motor and am happy with the tune I got with it.

Jim's right about the problems with full WOT runs, but that's half of the fun, trying to find good places to ride and tune. I just take the laptop with me and stop at a fast food joint to download, analyze and upload. Then go riding some more.

I wired the unit into the Acc plug under the seat so I can turn it on and off so I don't waste time recording useless data.

i am  a fan of the thundermax. have also used twinscan plus to tune the pc3.

my opinion? if you have a great tuner and he likes the pc3, keep it that way. sounds like you are happy with his work. he can put your map on a thunbdrive so if you have a pc3 failure, anywhere, you can just reload the map and enjoy your trip. you will also be on the same dyno with the same tuner, so yo can see the actual gains/losses from your changes!!!!!!!!!!!!!

Whew,  I am glad that someone finally is. 

Since this is now what is on my bike.  So far ---- only about 300 miles --- I love the way my bike runs.  Have not had a chance to test at different elevations or in the sticky, hot, humid days we get round here, but in the cool days in my normal riding radious, works good.

been involved with em since beta-------have any questions, just ask!

i heard they do not utilize the spark knock sensors is this true? do they have provisions for adjusting timing and rev limiter?

no to knock sensor. yes to other questions.

If my tuner loves it, promises me that if I don't like it, he will put in a Power Commander on his dime if I'm not happy, and my bike seems to love it too.  Am I one of the lucky ones? 

Please just say Yes!
