RE: Terminal Velocity vs. Thundermax Closed loop
This topic has been beat to death from the past. Do a search on TVII and you'll find some interesting information. Just like a lot of aftermarket parts put up a disclaimer stating for off road use only, its for the sole purpose of keeping the EPA off their backs. Jim at Terry Comp has stated via the phone the unit operates below 14.7. But they are not stupid and aren't going to advertise it and get slammed by the EPA. The information on their site is old and in bad need of an update. Keith Terry the owner will tell you that right off. The unit has been around for a long time and is sold under a different name for Metric Bikes. I believe the name is "BB" something. Keith handles all the HD's with the TVII.
Ask yourself some questions. How many TVII's do you see for sale by owner? You would be hard pressed to find one, because the owner is happy with his purchase. They've been selling them longer than Tmax. How many posts do you see up here with someone having a problem with a TVII? Once again you would be hard pressed to find one.
You accept with blind faith that a Fuel Pak works, or the Cobra works. You accept that a piece of wire with a resistor can lower the AFR .5, as sold on Night Train.
So what is so hard to believe that a TVII can make the Bike cruise in a richer mode than 14.7?
Now I come up here and daily see posts about people having problems with your unit. I see it every where I go. What I don't see is any posts on the TVII.
I suppose your going to say because they don't sell any.
Before this Bike I had an 07 Wide Glide. I put on a SE Air Kit and a Python 2 into 1. When the bike was new it popped on decel and surged at slow speed. Now I added these goodies which surely would have made it leaner. I also added a TVII. No more decel popping, no more surging, and my fuel mileage went up.
I'm dealing in facts

Honestly to answer your question I was just trying to get out of this thread and every time I did somebody else came back knocking the TVII.

Just curious why are you bumping all these threads with the TVII in it back to the top?
Honestly to answer your question I was just trying to get out of this thread and every time I did somebody else came back knocking the TVII. There's quit a library up here already of post discussing the TVII with many an owner responding positive. I realize it is not for everyone. For those who seek to squeeze the most out of what they have, I wouldn't recommend it.It's a simple unit that only requires installation. My goal was simply to have a Bike that runs good, and I didn't have to tinker with it anymore. When I say run good, my definition is a smooth running, reasonably powered motor that gets decent mileage. I'm not looking for a stump puller.
I did the SERT on my last ride an 07 Wide Glide. They squeezed every last pony out of her. My fuel mileage was in the 30's. Living in the Phoenix area, the weather here is quite extreme. You can have mornings when it is 40 degrees and afternoons in the 70's. Not to mention the summer months when it never dips below 100. This was a major part of my decision. I wanted a unit that could adjust for cold weather one minute, and hot weather the next. Anyone who has ever had a carbureted bike knows that one extreme requires the bike be richer, and the other leaner. You can also go from no altitude, to over 6,000 feet in an hour. Once again I wanted a unit that would adjust.
Thats what directed my decison. That and I didn't want a unit that I had to mess with. For my simple needs the TVII filled the bill.

So to review...I wanted the TVII seemed simple to me...I already had the SERT, did not like the dyno runs at the dealer (harsh on the engine)...got convincedby all the responses of the post that I re-bumped back up that maybe just maybe the TMAX is more I wanted for 268.00 dollars more...after furtherdebatethe decision was made by me...the bike runsgreat...not hard to install...my speedo is now accuarte...fuel mileage is great...and I can look how my engine is running ifI chose to (I have not yet)...because I just plugged it in and it played...sweet.
It is not my goal to tell people or even argue a point that I made the best choice because I may not have...you on theother hand say you do not knock other similar products but you do and you have convinced yourself that this is as far as you need to go w/ your engine, and it may not...perdicting the future is not my fortay...but obviously is yours...I have been riding and messing w/ bike enginesfor 40 years, I don't expect that will change any time soon...since I am only 46...it is a "been there done that" thing...and I believe most of the debates you are having over this issue is w/ guys who "have been there and done that",otherwise their passion would not be so great...they just may have another goal than you and I...There end may very well justify their means...IMO...02 cents

RE: Terminal Velocity vs. Thundermax Closed loop
Thanks Ultra,
Now this is communicating. I have learned more from your one post than all the others up here. Up till now I never heard of the eight page manual. After reading post after post of these guys complaining about fuel mileage and tweaking the rear cylinder 2 degrees on timing, and messing with the AFR table I was asking myself one big question. How the heck can they call this thing auto tune?
But what you have just said is exactly what I have been looking for. A bolt on unit, that you simply installed and it ran great, and has improved over time. You didn't have to read the Bible of tuning, and yours autotuned itself. Now if I saw more threads like this I might be tempted to buy it. I don't want to have to mess with the bike. Like you said, I just want to bolt it on and see a positive change in the motor and the more I ride it the better it gets. When you say good fuel mileage, just exactly how good?
Sometimes a simple answer is the answer.
Thanks

RE: Terminal Velocity vs. Thundermax Closed loop
I ride w/ all wifes and mygear...rain, cold(sweatshirts), leathers, gloves, polishes, towels, maps...ect...I keep the rear trunk for what I pick up along the way. My point is that my fuel mileage is effected because of my weight...I check my mileage every time I can, just because I like to, it entertains me...Anyway...because of this weight I put a rear tire on at 3000 miles...which the weightdoes effect my mileage. I am willing to say and have seen 48-50 w/ no weight (gear)...and I rode like I don't own the road...(thats an oxymoron)...

All I can add to this is I for one installed the TVII on my bike and have nothing but good things to say about the product. I like the idea of self adjusting. Bike runs cooler, leaner, smoother and more responsive.

RE: Terminal Velocity vs. Thundermax Closed loop
Thanks Ultra61 - I read through a lot of this and the TVII and PCIII - to help me better understand and think about how much of a PIA the installs might be or not. When I first looked at the eight page Tmax - I thought I would have to do the dyna install - good think I do not have a dyna..... any way thanks again
