Turbo Dynamics

Anyone had any experience with them? I have a M1100T coming and obviously want to increase power. Some guys have said the EZ Jacker and Hi Jacker have been problematic, but the Turbo Dynamics Reflash is a damn good system. I would appreciate any inout before I drop some $$$ on one of them. Here is the link to the TD stuff-

http://turbodynamics.mybigcommerce.com/4-stage-ecu-reflash-for-m1100-turbo/

I read some guys on HCS loved it. I have always used Boondocker in the past though.

Why in the hell is my sled not shipping from Cat to my dealership till 12/02? Man, I am going frickin nuts waiting ! :)
 
Hmmm.....kinda damned if you do, damned if you don't. What I have read is that it is a great system on the Z1T. Supposedly they are changing the setup slightly for mountain conditions. I am not interested in running race gas or pushing 300 + hp through my sled, but 250 on pump gas with no chages sounds damn good. Plus, simply turning a knob on the dash to increase power is pretty nice.

I called them today, but it was after hours. I sent them an email asking them to call me back. I do have some questions. Mainly about bolt on mods. What I read was that the mapping was fat enough for a pipe and can.

I have used Boondocker for years. 2004 M-7, then Big Bored in 05, 2007 M-1000 with serious mods. I will be honest, I am getting older and tuning is no longer as fun as it use to be. A simple plug and play reflash is sounding pretty good.

I also read the Boondocker Hijackers are having some issues. Main thing is reduced power due to percieved bad gas or detonation. Thing is, niether were actually happening. Some even took thier sleds to D&D and Bikeman to try and figure it out. Niether were able to. Some guys were able to overcome this and get them to run right through serious clutching. Doesn't sound right to me, but go figure.

Granted this was all on trail stuff, which I could personally care less about. I live in Jackson Hole and if I ain't Boondocking or climbing, I am not happy...... :)
 
Is Ben with Turbo Dynamics? I would really like to hear how it performs if it is. Can you keep us updated?

Looks like Bikeman is the closest dealer to do the flash to me.

I can't do crap right now because my M1100 Turbo Limted is not shipping from Cat till 12/02.

The TD stuff is really well documented. The exhaust and the turbo outlet I plan on putting on my sled.

As for the reflash, I'd wait until they start publishing at elevation numbers. I frankly couldn't care less what it does at sea level, and with the Turbo already altitude compensating there will be a limit to how high they can go with the stock turbo.
 
What is a 2004 M7?
Sabre cat or an F7 maybe...
2005 was the start of M7, Just saying :face-icon-small-sho

My bad, I got it in Nov of 04 but it was an 05. Big Bored it and added Nitrous in November of 05. Got my M1000 in Nov of 07.

I agree. I do most of my riding between 8000-11000. The system on the Z1T was good up to 10,000.

BUT, even a 50 hp gain for 750.00 is not bad, not bad at all......if they can acually get to 264 hp on pump gas, then for 750.00, that is pretty phenomenal. :)
 
My only issue (or question) is the increase in RPM that the TD tune gives, what about the valve train???? Adding 500+ RPM's to this motor is un-proven, valve float, spring failure, etc. I also have been told the KNOCK sensor is not reliable at above OEM spec RPM. TD has been on the snow for only a year or less, I want to see what happens over time. I am partial to D&D because I have some involvement in the 600HP Outlaw sled but am not employed by them nor am I a spokesman. I hope the TD tune is a good tune and everyone is safe using it. I just wonder why all other tuners only get 240HP out of these machines, even Speedwerx who has close ties to AC is at 240HP. I guess the TD tune reduces boost and timing when KNOCK is detected, thats great but I want consistent power, so I will do a BD 2.0 and METH, 250HP PG all day no worries or reduced HP. They build some nice stuff and I applaud their effort to increase the quality on all aftermarket parts as it will make others up the ante, I couldn't say anything bad, or question their product on HCS because you will get flamed so quick as everyone has TD FEVER over there.
 
If your ran the same hp, couldn't you just work the clutching down 500 RPM?

I didn't know the Turbo Dynamics flash increased RPM.
 
you could clutch it lower but if they are building more power at the higher rpm then your losing out. so really it depends where your motors building its power.

I talked to Ben from TD at haydays for quite some time. He is well aware of the size of the turbo on ths stock sled and how it correlates to higher elevation. This being said he has not done much testing at higher elevation. I beleive it could be a good setup at high elevation, but the stock turbo won't be able to support the high hp numbers that he is getting at near sea level. This is true with the Hijacker as well.. I believe the ezjacker 1.9 should be able to maintain the same hp from sea level to 10000ft though due to the hp setting being lower. Glenn Hall said in another post that higher rpm needs more cfm. . . Which needs a bigger turbo. So clutch to stock rpm. Alot more cfm to run 500rpms more will work the little turbo that much harder. It seems as though TD can build a custom map for the mountain guys he just needs to find a good performance dealer in the mountains to colaborate with on the project.
 
Alright, seems we have two seperate issues. One, is the Turbo Dynamics reflash going to work on Mountain sleds. On the Z1T, it was set up for sea level to 10,000 ft. I do not see why this would not transfer into the M1100T reflash.

Second, anytime you add power, whether it be from bolt on mods, NOS, big bore, etc.... you are going to be adding RPM's to your existing clutch setup. You need to add weight and possibly change a spring to keep the RPM's in the specified range. Why would a reflash make the hp or torque curve different in regards to the RPM's? The stock setup is made to produce the power and torque within the engines rpm range.

For example, my M1000's peak RPM stock was 7200 if I remember right. I added a bunch of bolt on stuff. HP went up about 25 hp. I was taching 7800, but I never felt I was getting additional hp above the 7200. It actually ran like ****. Threw some weight at the clutch, max RPM was 7200 and it ran like a scalded cat.

I haven't seen a hp or torque map for the M1100T, so I really don't know where it produces peak hp. Whenever you throw hp at a one gear machine, you are going to have to change gearing or clutching to stay within the RPM range. I am into performance boating. My last boat was a 22 ft Donzi. It had 320 hp stock. I was running a 1.5 gear with a 22 pitch prop. I added heads, intake, cam and a few other things. HP went to around 400. Max RPM's on the engine were supposed to be 4800-5000. I was hitting the rev limiter at 5200. I switched to a 26 pitch prop. I picked up 10 mph and was comfortably at 4900 rpm. Why would added hp through a ECU reflash be any different? You are simply adding HP. You will need to reclutch regardless of RPM's to get the most out of the additional hp.

In all the reviews I read about the system with the Z1T, reclutching was mandatory, but I never heard of one losing hp due to the reclutching.

I am just trying to figure it out. I have been adding hp and tuning 2 strokes for 15 years. I have never messed with a 4 stroke sled, much less a turbo one. Like I said, just trying to figure it out and any help is appreciated.

You should get a hold of that TD guy (ben i think) sounds like your the guy he would like to have for testing. go over to hcs and see if you can pm him I'm sure he would respond even though he is apparently quite busy! lookin forward to this company's mountain program for these motors!!
