ORIGINAL: SGDude

With the T-max you can look at each cylinders fuel ratio and make seperate adjustments per cylinders. Also heat plays a factor on fuel conditions. With the T-max not only is it a closed loop adaptive system, but you can make corrections per cylinder.Does a rear cylinder run hotter normally? Is a richer mixture usually make for a cooler running cylinder?
Actually, the T-max doesn't allow tuning per-cylinder of the AFR, only timing and that is relative to the front cylinder timing, not completely independent.
Well I beg to differ with you, but with that advance software we use as a dealer it's do able. At least it was when I walked out of my dyno room 10 mins ago. Dam at least I hope that was what I was doing.......it said I was doing that? The AFR mixtures were improving......the dyno numbers were going up? That's why I can comment on the T-max and won't comment on the adjustability of the software you refer to,because I haven't used it or read up on it. I don't like using technoligy that is archaic.I've owned my automotive business for over 25 yrs we sponsor 3 turbo Scions putting out 400 hp from a four cylinder......so when I play, I want something that is adaptive and a closed loop.Runninga canned software program just doesn't make sense to me.....but that's just me.

Wait I'm confused, are you talking about the Tmax s/w or something you're using to adjust a bike that has Tmax installed on it?

Hmmm I would have to get up to speed on the pro-tuners capabilities, before I could be as gun ho as a few people are on this product. what concerns me on canned software programs would be things like atmospheric(area we live in)conditions that will effect your fuel management. With the T-max you can look at each cylinders fuel ratio and make seperate adjustments per cylinders. Also heat plays a factor on fuel conditions. With the T-max not only is it a closed loop adaptive system, but you can make corrections per cylinder.Does a rear cylinder run hotter normally? Is a richer mixture usually make for a cooler running cylinder? I think Phil you stated that the system was 'arcane' meaning a mysterous secret.....there's nothing mysterous at all about a the 20K bike we are all riding compared to the technoligy that is present with the multi sensors on an automobile. If anything I would say it's archaic, like auto's back in the early 80's when the first computers came out on automobiles (not european). I'm also confused on why alot of people that go with this 103 kits are buying new cylinders vs just having them bored and fitted for the pistons that they are installing? The other factor would be with all this horse power being made.......what about the bottom end? When did HD make the change in their sprocket shaft bearing, I believe it was in 2003? Anyone considering updating it for the extra HP? I think anyone that understands cam durations etc. has someone that can run a flow bench and understands what the customer is trying to obtain ......can put a package together for about 2000.00 plus labor that will put you in the 100/100 plus HP club on pump gas. There are alot of good products that are out there.
Thank you for pointing out my miss use of the english language. I checked dictionary.com and you are correct with your definition of arcane. MY BAD. I should have used a different word... perhaps: antiquated would have been better ...???... equally satisfactory is archiac. That was what I was attempting to say ~ not something synonomous with mysterious.

I have been running a DTT TCFI-IID for a long time. I have personally installed at least 6 and helped with installs, setup, and troubleshooting of dozens across the counrty. I have a reasonably decent understaning of how and why it works, as well as some of the shortcomings... Probably no where near as well as you, but "decent" nonetheless. I understand, like, and prefer closed-loop systems. In fact, when you couple a ProTuner with a SERT, you endup with closed loop dynamic tuning of AFR ~ similar to the TMax / DTT.

In the context of the ProTuner, when someone says "they give you a MAP", that means that HQ provides a SERT MAP for your specific HQ build. This is particularly good for getting timing very close to optimal. Then, the ProTuner dynamically tunes in the A/F Ratio. It is not like a static "canned PCIII MAP".

I agree with you on the bottom end thing. It was 2003 when the MoCo moved away from the Timken bearings and I belive the cranks have changes at least a couple times. While it is certainly debatable, the current rask of runout /bearing / crank issues likely has far less to do with the bearing change than it does to crank quality (sissoring). You can do Timken conversions all day long, but if the cranks still twist and create excessive runout, there is no bearing on earth that will withstand it. The bearing failures are much more symptomatic than root cause.

I had no problem with my 98" motor that made well over 100/100. It's a 2005 and crank runout was .0025 when I dis-assembled it for the upgrade I'm doing now. Some fail some don't, which is true for stock and modified motors. Am I taking all precautions with the new build? HellYes.... Timken conversion, new Jims crank: split apart,balanced, reassembled, and welded before it is ever installed.

Guess I'll ask Santa for

The sert allows me allthat the t-max and DTT does as far as adjustability for fuel and timing front and rear cylenders independantly and the pro tuner alows the real time adjustments (closed loop) with oxegen sensors to allow for changes in elevation, exhaust, intake, dirty air filter, so on and so forth continuosly in real time.

Does the pro tuner use the stock 02 sensors or change to wide band?

Don't have mine yet, but I am almost certain that it includes sensor(s) it requires.

Sugarbear: The Pro Tuner will use the stock sensors on your '07. The narrowband sensors will do the job. Wideband simply expands the a/f range to 10.0 to 20.0; a range of a/f coverage that our bikes don't need. HD's ECM software limits the adjustability of the '07 and newer bikes to 14.1 to 14.7, the limitation is the software not the narrowband sensors.

Phil, I agree with the botton end improvements especially welding the crank. Don't worry on the spell check, I just wanted to make sure I understood what you were saying.Trust me spelling is not one of my strong points.

I have friends that are partial to both. But,I see the guys who like turning their own wrenches using the TM a lot more than the SERT. Using SERT means you have to go to HD dealer for tuning/maintenance, which means anytime you have a question about whether your bike is running right or not, you have to drop it off and pay the $90 bucks an hour to have a technician "look" at it. I know, some of you guys on here from dealers and would strongly disagree with me.... but, you don't work at a dealer in northern VA, or eastern MD, or within a couple of hundred miles of either... Personnally, I'll pay double to keep my monies out of the pocket of a dealer that won't install rivets in a tour pak because I didn't buy the hinges from him.
I don't see much about it on here, but I have been running S&S VFI for 5 years now. With the addition of Closed Loop, it works fine for me.

Default RE: TMAX vs H-D RACE TUNER

Ok please forgive me before hand. I am a novice and have none of the knowledge that most of you have. I have an 04 softail standard stock except for the stage 1 ac kit, v&h longshots without baffels, sert installed. So from what ive read the pro tuner pretty much makes it plug and play with the sert. Where do i get one? Would hq give me a map based on the what i have installed if i dont have one of their builds on my bike? I dont have a clue about air to fuel mixture and all the other stuff discussed above. thanks for helping this newb understand
