Have been waiting for winter to come to make a few improvements to the ol girl, and the first thing on my list is a new fuel managment system. I was all set to order the Thundermax w/ auto tune when I discover the TV3. Seems they do the same thing and the TV3 is $400 bucks less.

Anyone with any experience with either one, Recommendations??

 

The TV3 sure ain't something I would do, even if it didn't require running sensor leads all over the place and splicing into a power source! I don't plan on doing anything cam-wise which would make the MAP sensor unusable, so I'm pretty sure I wouldn't do a TMAX either (or a DTT, which is what I would actually use of the two). My (first-hand) recommendation is to obtain a TTS tuner and use the excellent stock Delphi EFI to its fullest. The Moco broke their relationship with the makers of their "SERT" and this is the next generation of the SERT with more capabilities and functions. You can get one from either of a couple forum members for a fee much more reasonable than you'd think, and if you're so inclined, you can "autotune" your Delphi yourself with this unit, without a dyno.

 

First off the unit is plug and play you don't have to splice anything anywhere, now that being said I have TV2 and it works great with no Dino the only one that works right w/o the Dino, it's easy to install but you need to read ALL the instructions for the routing to the 02 censors.

 

I have one on my 07 e-glide, i never installed it but my indy did, he swears by em. But he also sells most other tuners, he will put on anything you would like,,,, all i know is it makes a world of difference in the bike, or at least it did on mine

 

See http://terrycomp.com/documents/TV-3Install.pdf for example. Steps 2-4 have you routing harnesses to the throttle position sensor, the crank position sensor, and the O2 sensors, where each are locally intercepted. Step 5 has you using a "supplied T-Tap and Blade-Terminal" to splice into a +12VDC source.

No thanks. And these things aren't adjustable or programmable in any way? No thanks. For a couple bucks more I'd invest (again) in the TTS tuner.

If you have a bike with open-loop-only EFI these things might be worth considering. If you've got a Delphi closed-loop system there are lots of ways to better spend money. With the TTS system at the top of the list for capability and value at any price. Trust me.

 

Glens , you seem to be up to par on a lot of this stuff and seem to be pretty smart when talking about tables and comptuter things and maps and so forth,
i just dont have the computer expierence to do all that mapping and changing tables and all that to get your bike to run at its best. I wish i did, but kudos to you for your knowledge.

 

It's really straight-forward to "autotune" the TTS system at home. Not much need for extensive knowledge about EFI or tables, etc.

 

What is the TTS system??

 

well, ive been studying all thiis on this forum and every thing ,,and have been thinking maybe after the first of the year sometime and i have a little more money about going to a different tuner, ,, i dont think i want a pcIII, from what i have read , if i leave florida and head for elevation i would probably need to carry a laptop and put a difeerent map in the thing, ( maybe im wrong ) i just want something with an easy install and not a bunch of dyno time. something that will auto tune pretty much to the way you ride and to elevation or changing loads.

 

Changing elevations would get picked up by shutting off the engine and restarting it a time or two along the way. When the computer first fires up it gets a static barometric reading via the MAP sensor and it bases its calculations on that static value. This would be an issue on an open-loop system (such as the PC-III piggybacked on a closed-loop Delphi). It's still a bit of an issue even on the closed-loop system, but things won't get as "out of hand" (as much as they even will) while closed-loop service is being used.

With the TTS tuner, there is a manual set of steps you can do to "autotune" the variables you program into the bike's computer. First you set the bulk of the fuel table to "14.6" which puts it into closed-loop operation. You can't do the 100% (and I'm thinking 90%) engine load columns this way, because it would be too lean for operation in that area. But when you make those changes, plus a few others, to a map and load it into the bike's computer, you go and ride, taking a special type of datalog while doing so. This, alas, entails having a laptop hooked up and running Microsoft Windows during your ride. But then you take the resultant map and fire it into the TTS software to "correct" your base map. You do this a couple or three times and you've got an as-well-tuned bike as you can have for how you ride. With sufficient care, it can be correct for how anybody rides. Either way, it will not run better with any other system currently available. If you wish, you can take the bike to a dyno and interactively hit all the necessary spots in the programming via the software and drastically reduce the amount of time on the dyno. This would result in an even better-running-yet setup, but it's really not necessary for most of us.

I cannot recommend the TTS system enough, nor dis-recommend anything else instead of it, enough, at this time. If you're going to go pretty radical engine-wise, then the Daytona Twin-Tech replacement EFI would be the next best thing. Maybe if you needed to. Our current Delphi is a pretty sweet setup.
