O2 sensor eliminator mod (By Kev with the help of dazmatic)
Note: Jump to latest (2012 on) plug 'n' play version here
Well, I've finally got a working version fitted onto my bike this morning and tested it whilst sitting on my driveway. Initial indications suggest that it works as well as expected if not better and would appear to not interfere with the running of the bike and was actually a lot easier to install than I first imagined it would be which is also good. I did however go for a ride to get some shopping and well... WoW No surging or bucking, bike rides a lot lot more smoother now. Was an absolute dream to ride! It produced a good map which I thought I'd saved to my PC but hadn't! I now can't be arsed to go back out again and setup my laptop to read it but will do it tomorrow or something. But I assure you, it looked good. A few pics of it in place. Be aware though, this is just a prototype. Hopefully the next one will be pukka! Mod in its location whilst installing. Sensor Live feed to the mod taken from the loom, from the same place where the live feed for the PCV is taken from. Wrapped in special electrical wrapping tape (not that nasty sticky tape!) PCV Under the tail section with wire for analogue feed (PCV can now tell the engine temperature!) and my Autotune Switch and Autotune just to the right. The finished prototype installed under the seat and held down with sticky pads.

Looks good but will this mod only work with a PC5 or will it work with a PC3

Unfortunately, I cannot make any promises yet.
However, I don't see why not so long as there is a bit of dyno time involved. I don't have a dyno near me hence why I used a PCV with autotune. Not to mention I can mod my bike and be able to remap with that new mod. All this mod does is keep the bike in open loop mode so that the entire rev range can be mapped. No more 'Cannot map at 20% throttle between X and X rpm' Bare in mind, this mod is only for bikes that have an O2 sensor, so 2007 - 2009 I believe? Something like that anyway...

Haha...
I know it will work, Kev and I have proven that. But thats not the thing that needs testing really, however, I can't say as of yet what is. I'm sure it works, but just need to be doubley trippley sure of it. The real thing is, putting together something that can be distributed. I need to compile a shopping list of bits and create a design that can just be wired up easily straight out of the box and be of good enough quality too. As you can see, what I've made here is (I think) rather crude and if I do decide to make more would like to make something of a better standard. I know of a design that I would like to use and need to trial it first but that requires cash, something which I don't have a lot of at the moment so may have to wait till I can afford to develop this a bit further.

This is a joint venture between Dazmatic & myself.
As I mentioned before I found a way to turn off the the O2 sensor on our XT's a few months ago & could prove that it worked by looking at the air fuel ratio while riding. I made up the mod using relays & temp switch's which was to complicated for the average person to wire up, I asked for help & enlisted dazmatic to help me make an electronic version that was easier to wire up. Dazmatic has done well, the mod will need to be tested for a while before we can say it is a reliable working mod. We will need to build special fuel maps for the PCIII & PCV to go with this mod. Yes it should work on any XT660 with a O2 sensor, but you will need a PCV or PCIII for this mod to work, as a new fuel map will need to be made. The proof. The surge before. http://www.youtube.com/watch?v=ZwTfuwZZ848&feature=channel The O2 sensor turned off. http://www.youtube.com/watch?v=1Y9mqJtXtm4&feature=channel

I will definitely be interested eventually, as soon as I get myself a PCIII. |

Will be on my bike tomorrow & tested on the dyno on the 27th. We are still working on a better way to run the fans.
Dynojets Emulator is close hopefully, as some of the UK's dynojet dealers have been given the pricing on the Emulator.
