Guys and gals...I ordered the Copperhead ECU for the wife's KQ700 today... they claim it gives a good HP improvement... It should be here by Monday...I will test it out and let you know...

Copperhead ECU

Thanks Voodoo, ...now you got me thinking that I need one,...then if I get one,.... guess who will all also NEED TO HAVE ONE (Annie)!! You are costing me money buddy.

I have been sandbagging the Nyroc forums where they have been going through the whole process of group participation to provide input to VDI to help develop their R&D for the ECM and unfortunately they have a bunch of new, young ATV owners that seem to have a host of "THINGS" that they are confused about or think is a ghost problem,....A little hard to follow for me while they (VDI)is still developing the product.

I am a little older with the developed patience that comes with age and can Waite until the VDI ECM is perfected to 99%, after all it will cost me in excess of $1K large because Annie will also need one in order to continue to kick my butt.

So my friend I await your installation and through test of the product with your evaluation, ...please keep us informed.

Will do Stutz.... I am gonna do some time trials in the 100 yard and 50 yard range before and after .... I will keep you up to date..

Yeah, keep us posted Voodoo. I agree with Stutzi, there has been so much info on the VDI, on how it works awesome, and then some people have said it has hardly done anything. Seems we can't get a straight answer, or I should say a un-bias accurate answer.

I know Voodoo will provide it, he has done an excellent job with the Outlander and its power chips, and exhaust info.

I was going to go with the chip and exhaust with the my KQ 750, but the more I think about, I don't think I am going to do. I am saving all that for my Brute since that is pure trail performance. Will see what I ll do with the KQ 750, after I run it through the 3 Testing Phase Process we are doing.

Keep us posted Voodoo.

I am quite satisfied with my VDI. It doesn't turn the machine into a sand rail, but then again what does? It makes the King Quad run a lot better than stock.

There is a two position switch and one of the loads is a version of the stock ECU parameters on position 1 and position 2 is a VDI enhanced fuel and ignition load.
You must shut the machine off when switching so that the apropriate 'map' loads when you power it up.
I tried an experiment on a ride one day, after I'd become quite accustomed to the VDI and how the machine ran. The VDI didn't seem very earth shaking any more by that time you see, it was just my ATV and the way it ran. Pretty good. But was that darned VDI really worth it?

Well let me tell you, in position 1, the 'stock' setting.... what a dog! I hated it. Felt like all of a sudden there was an invisible fat guy sitting on my rack. Or somebody had let most of the air out of my tires. Oh it ran alright and a guy could get used to it, but a whole bunch of zip and livelyness was just not there.

That's the subtleness of the VDI. It runs well, you ride it and have fun, you can wheelie and all that, but you don't really know what you got till it's gone.

Copperhead owners who are saying 'it doesn't do much', should try that test.
Puts the smile back on.

ps. One thing surprised me: I went on a ride last week with some guys and three others had King Quad 700's. When we came to a stop before darkness began to settle in on our return leg, in order to fuel up, I'd thought that I'd be the guy with the worst milage. After all, I have 27" ITP's and the VDI along with the Dalton clutch kit and Coop45 mod, and I had just gone down to my last bar of fuel.
What do you know but out of the other three KQ's, one had two bars showing and the other two were down to one bar just like me!
Go figure.

I wonder if one will see much better performance from the VDI with an aftermarket pipe. Many claim that a pipe helps performance even without the VDI but it may be hype. I know neither are especially cheap but I may do both down the road. The Dalton and Coop45 mod are the ones I might do first. I am still much happier on the 700 than I was on my old 450 KQ.

IMO ...A pipe will never give the HP gains that they claim.... Some of these pipe manufacturers claim that there slip ons increase HP by 10 or more...that is BS.... I have tested 3 different exhaust systems on my Outty and the one I settled on (Ron Wood) does provide in the ball park of 3 to 5 HP increase,, but not the 8 to 10 like they claim....Now... this Ron Wood's exhaust is especially made for Can Am....
IMO .... the best Slip On for the Suzuki is gonna be something like the HMF or similar...

Can't wait to hear your opinion on the Copperhead. I, like many others, have been doing alot of reading about it on the NYROC site. One thing I found interesting was the fact that alot of people are leaving the stock ecu in the stock location, in case there was a failure with the Copperhead, and finding room for the Copperhead somewhere else under the seat. I guess if you had a box you could just carry the stock ecu with you in that. Sounds like a good idea to keep the stock ecu with you just in case. Hate to get stuck on the trail!!

I would shore like to know about what the differences are between the KQ700 & KQ750.

I talked to Lyle at VDI and he says the later software should work great.... What a lot of the problems occurring on NYROC is the other bike mods that these folks have on.... such as bigger tires, clutch work, exhaust, etc... Lyle told me if you have other mods like that then the Percent fuel enrichment would and can be adjusted.... For instance the unit comes set up for stock at 30% fuel enrichment at the stab.... If your bike has huge mud tires then it will not burn the fuel as quickly and thus you would adjust the Fuel enrichment down to 25% .. or vise versa if you have cluctch work done and your bike burns fuel quicker...you can adjust the Enrichment up to 35%... My KQ 700 is completely stock with 26" tires..so the set up from VDI should be dead on...

That is what I got from Lyle on the phone a few minutes ago....

Yeah Voodoo I kept our ATVs stock also except for the BigHorns that I mounted and they are the stock 25" size to fit the stock wheels but they are still a larger diameter than the stock dunflops, no pipe or clutch work and don't plan to do any. The VDI should plug and play just fine in your case and I cant wait to hear the results.

Me to Stutz.... It will be here on Monday, but I won't be able to put it on and test until late next week.....

You bet there's a box, in the right front fender. My stock ECU in in there wrapped in bubble wrap.
Not that I think the VDI is going to fail any sooner than the stock one but since I had an ECU fail in my last ATV, stranding me on the trail, I wanted a spare anyway! Since I know darned well I'd never have spent hundreds of dollars for a spare ECU just for the peace of mind, having my stocker as a spare resulting from my getting the VDI, suits me just fine.

Besides, owners want to keep the stock ECU in order to get the service diagnostic codes, which the VDI does not provide.

On the subject of spares, it's a good idea to carry a spare fuel relay. This little puppy can burn out on the trail and leave you dead in the water.
