ckedd and I use the innovative hand held version to tune our quads and rails. Weld a bung on and buy a plug so when you are not tuning you just thread in the plug. It works great for all applications but especially to verify the a/f with nitrous and turbos. And it reads as a ration instead of a volt that you have to convert. Not a big deal to convert the voltage reading but when you use narrow band and wide band at different times the voltage changes are opposite and the optimal value is different as well. So as not to confuse someone, the innovative only uses the wideband o2 sensor. We have used the narrow band previously with poor success.

 

looks good, i'll be getting one when i get my motor done. ODP do you know if that gauge is waterproof?

 

i bought an autometer one with a 3 wire "heated". it would work good if you could go out to the highway in 5 gear for a long distance. dyno was still better.

 

I believe they are weather resistant but not dunk proof. I've held one in my hand and studied it for quite a while, they look pretty sealed to me. But I dont believe they are dunk proof. There are other options, including what was mentioned earlier - the hand held unit. While I dont have any experience with that one, it may be the way to go if you are planning to cross a river or something! LOL Just make sure and leave that one back at camp before you leave!

 

I recommend the hand held unit. You can strap it to the bike and tune it. take it off and leave it an camp. Use it for all the other machines you have. If you start to notice a stumble in the bike you hook it back up. (takes 5 minutes) and run it again. When you go to a new riding spot at a different elevation you can hook it up ahead of time. We switch the unit between 3-4 machines each trip. When you use the permanent unit the leaded fuel will cause failure after a year or so. I would guess 50 hrs as odp has stated. The O2 sensor alone is around 100$. I really like the unit we use because it can be used for different bikes and rails quickly.

CrakerJack, that is exactly what I need to be able to do. Move it between machines. Exactly what do you have that you use, and how do you bounce it between the rides. Splitting a cost of this between the three of us that ride in my group would be much more feesible...

 

You have to weld a bung in the header of each machine that is being used. They send you one bung with the unit and a bung plug. You can order more. The unit is made by innovative resources. It is sold several places but summitt racing sales it for as cheap as any. Order a couple extra bungs and plugs with the hand held kit. When you want to switch it from one machine to another you take the O2 sensor out disconnet the alligator clips from the battery and place them in the new machine. You have to plug the bung on the machine you took it off. A 9 volt runs the hand held computer and the alligator clips give enough power to heat the sensor. (I don't recommend ever using a non heated o2 sensor, I have never gotten good reproducible numbers from them and they go bad quickly)

 

So are you using the LM-!, or another model?
