O2 modifier

[altonk]

I have a race air intake, Leo Vince exhaust silencer removed and a juice box. I don't know what the juice box was doing to the o2 signal but I put the o2 modifier on and it was a big improvement in low rpm drivability. Thanks Ken

Btw doing the aerocharger turbo in October woo hoo :2thumbs:hyea:

:2thumbs: Just installed the O2 modifier as well (Juice Box,Hindle and KW Filter ) What an improvement as I was getting popping and some backfiring on desell. All gone now with a slight improvement with throttle response and running a tad cooler !

However you have to remove the race air intake and the juice box and replace with the Aerochager pressurize intake and Aerocharger juice box. :thumbup:

I put the O2 on a couple of weeks ago.(Hindle & Green filter). The popping is gone but now I get one big Bang every once in awhile when I decelerate. :dontknow:
It does run better and smoother in this hot weather though.

I'm glad it's working out good for you guys. It's funny how the guys that don't have a o2 sensor want to put one in (bike guys) and the guys that have one take it out. I ran with Ken's setup for quite some time and wound up removing it. Didn't seem to help anything with it in and I loss about 2 mpg. :dontknow:

Yeah when I get the turbo I'm gonna have a garage sale of mods and stock parts :clap:

I will disagree with you on this one from what I've seen on the forums most people are keeping their 02 mod. Lets take a pool. Seems to me that every machine is a little different, different mods that work for some may not work for others.

When I installed my JB I went back to the stock O2 sensor and lowered my fuel pressure back to stock. Tried all settings on the JB and could not get it to run as good as with just the O2 mod and fuel pressure cranked up.

Added the O2 mod back and it instantly ran much better.:2thumbs:

Plus it's one more sensor I don't have to worry about going bad!

:agree:A mod like the cold air intake did not make any noticeable difference on my bike and others swear by it.

I agree that not all mods work the same for everyone but do a Google search for "o2 modifier" and "cold air intake" and you'll see that about the only thing you'll find for the o2 mod is some guys are doing it on turbo Mazda's and a few BMW's, cold air intakes on the other hand is used on just about everything from trucks to sports cars with proven dyno results. Without doing an exhaust gas analysis you really don't know if you're adding too much fuel or not. I would love to see a graph of what it's really doing compared to the stock o2 sensor.

For the record I also did my cold-air intakes about the same time as all the other mods--- can't keep em' all straight...:shocked:

I think you miss understood my comment. A lot of guys in the motorcycle world want a sensor so the fuel management can fine tune the mixture. By removing it you now have a fixed value just like the guys that's don't have one at all.

I'm sure your probably right but I thought we were talking about whats working with our Spyders.

I feel what you are saying. If I was actually going to do any serious fuel re-mapping I would probably put the sensor back in! That's why I kept it. For now, my modest (and mostly stock) fuel setup seems to like the O2 mod and is running just fine. It eliminated all that backfiring and stumble-bumbling that was going on. It's all about what your objectives are!

Now Doc and Altonk are completely off the grid man! :2thumbs: And I respect that. Altonk, how is the wing project coming? any new pics? Don't mean to get off topic, just curious...

Not much progress lately. Got distracted putting the spyderpops stuff and carbon fiber panels on, oh the o2 mod also. But the struts I salvaged from the wing on my old autocross BMW are all cleaned up and ready for powder coating. I decided to finish the carbon fiber and do the aerocharger first. Annoying things like having to show up to work and pay for these toys just keep getting in the way :gaah:

I hear ya! But at least I get to ride my bike in every day. Even today, On a wicked Monday morning commute, I just took it easy, made a few moves and had some fun. The trip home was even better. Sometimes I think I charge too hard. It was nice to roll off throttle for once and actually be able to see trees and nature and stuff! Usually it's all just a blur!

Well, I'll keep checkin with ya from time to time. You know I'm rootin for ya and I know you are building a monster out there!! Keep at her bro!

I rode home from midtown Washington dc this morning up the George Washington parkway at 6:30 am the traffic was going the other way great scenery and some good mid to high speed corners but the road surface sucks in places ( damn humvees and trucks)

Since I put the o2 modifier on the 4-6 k range is a lot smoother and predictable so I am doing a lot less apexes at 7-8 k now it's slowed me down a bit

But in the straights I find myself a gear higher now

It's a kind conservation of insanity thing I think

My bike has definitely changed personality since the O2 Mod. Power comes on much smoother now and acceleration has definitely improved. I don't feel like I have to be in that 7500-7700 rpm range now. And as a result, I'm smoother and consequently faster! It's weird man. But I like it!

I'm also learning to drift this thing. You can actually drift these things! You sort of have to use your back side some and shift your weight a certain way, but if you pick the right line (which takes a little practice) you can bring the ass end around and not really have to give much steering input and just power out. You can feel the slide but you just stick with it and you just rocket out of the turns. Dude it's sick! It took me a while to get the stones up to do it but I'm gettin there! I think if I had a slightly stiffer front end (i.e. better shocks!) it would be easier to do. But I'm still havin fun!!

Also like to know what Two Brothers changed when developing the JB .That is suppose to modify the signal as well and they used the Evo. modifier when developing it.
