O2 sensor

I just got my bike back from the dealer today. I put it in for a service so they could check the valves which got the all clear. Discussing the work carried out with the service manager brought up an interesting point for anyone running a PC, or the larger injector with the O2 sensor disconnected like me.

Before the service I had swapped back to the standard injector and reconnected the O2 sensor. During the service the bike generated error codes linked to the O2 sensor, caused by running the bike with it disconnected. O2 sensors have a heater inside them which, among other things prevents soot building up on the sensor. Running the bike without the sensor running cause it to soot up and will eventually trash the sensor as they can't be cleaned.

I got the bike home and removed the sensor (22mm ring spanner) and sure enough, it was covered in soot. I'm hoping it is not too far gone. It has now gone into my box of removed bits and been replaced by a blanking plug bought from my local motor factors and the larger injector refitted.

The sensor thread is M18x1.5 10mm long.

Good bit of info on the lambda-sensor sooting. For blanking bolt, the easiest solution is to source an extra oil drain plug. It's a perfect match, BMWs and many many others use the 18mm/1.5 threaded oil sump drain plugs.


Aaand I just happened to plug mine today, by the way
Just got a quick run around the neighborhood on paved roads, letting them know their favourite middle-aged motor-head is back in the business after a quiet winter.

Too early to go into detailed reviews of PC V on my bike, but... for what its worth, my X's first gear wheelies are now just a little blip of a gas throttle away. Very nice first impression!

Just to show (off) my PC V installation, here's where its situated under the seat pan. Velcro'ed on top of the ECU holder case. Installation was very easy, apart from posi-tapping two wires into crank sensor wiring, and attaching the ground wire to the battery, it's all just plug & play.




Riding impressions so far are very pleasing to me, it seems to pull very strong yet carb-like smooth throughout the throttle range.



Bike porn alert!

With this look on its face, I feel the bike is actually begging to forget about steady cruising altogether, and begging to hit the dirt with that authoritative "pcv'd" throttle.

Looking good Finn,

I don't suppose you would post up some pics, perhaps in the Farkles thread, of your headlight bracket. I would love to see how you mounted the projector.

Yes, dynojet in Vegas used my 2007 Xchallenge to develop the maps on their web site.

You most likely don't need the auto tune.

What configuration is your bike, do you have an aftermarket exhaust, modified air box, etc? That is what the map you can download is configured for.

Earlier in this thread I have posted the configuration of my bike when they tuned/tested it.

Bike setup

My bike is equiped with leovince silencer and thats about it as of now. Will also add a foam air filter and remove outer air box cover.

I have also read something about exchangeing the fuel injector for one that can deliver more fuel. Is the injector a regular bosch unit?.

With the power commander you don't want to swap out the injector. If all you have done is a muffler, and foam filter, remover cover on air box, then the stock injector will deliver sufficient fuel.

I think the injector swap is a way of getting more fuel without modifying the ecu, a higher flow injector delivers more fuel in the same pulse time as the stock injector.

Some good news & bad news.

Good news is that with the Power Commander, which richens the air/fuel ratio, the bike seems to definitely run cooler. I was actually starting to think my rad fan is non-functional, but it does eventually kick-in after a long while. Previously, with stock set-up the rad fan would kick in a lot sooner and keep fanning a lot more.

Smaller bad news is lowered mileage, this was to expected as well, I guess. I would say maybe even 20% lower economy on gas consumption. Maybe this settles down a bit, as I honestly think I'm enjoying the benefits of improved power by riding a bit (or lot) more aggressively on the gas than before. I'm using the 003 map on this, which is the richest.

Bigger bad news is my Power Commander V unit seems to have a serious problem, i.e. it is most likely a failed unit. Bike started coughing and cutting off during a ride (after total of 300 miles on the PC V), would not accept more than a tiny bit of throttle. Could still limp back home from the trail.

Throttle seems to work fine when on neutral, but gassing through the gears brought these severe symptoms. Also noticed that the PC unit's Status led blinks red ("Error") when idleing, little bit of throttle turns it back to green ("OK"). I then disconnected the unit when back at the garage, and bike runs fine with stock setup without PC. So I sort of concluded there must be something wrong with my unit.

Our national PC importer in Finland (Duell) is taking prompt care of this situation, will have a look on the unit and promised to replace it under warranty. Thumbs up for them on taking care of the situation.


Hope to be able to run more good miles with a new PC V unit soon.

Update: I got a new PCV on warranty, and got into installing it back into the bike. I loaded the 002 map into the unit, it's the richect map for a bike with a slip-on exhaust (LeoV X3) and Uni foam air filter.

I started the bike up, and let it idle, checking that all's well. It was, for some time, but then the bike started to die on idle. Sort of felt like choking to death slowly. To me, with carb'ed bikes, that sounds like too rich, fuel overflow.

I hooked my laptop with the PowerCommander software into the bike with the supplied USB-cable, to see if the software could show some tips on what's happening.

OK, I can see that the bike is idleing at about 1500rpm +/-50 rpm, and at idle = zero throttle, I can see the PCV is fueling the bike with +8% fuel compared to stock setup, with that 002 map. "Hmm, +8% fuel at idle, huh, what's with that?" thinks me. I then noticed that Dynojet maps 001 and 002 have 8% added fuel settings at 0% throttle at 1250rpm, 1500rpm, 1750rpm and 2000rpm.

I changed my map to 0% added fuel at those rpms at 0% throttle, loaded the map in the unit and fired up the bike. The result = idles fine, no choking up anymore.


Note: I'm living and riding right at the sea-level for prolly 99% of my time (Finland=rather a flat country, save some big hills up in Lapland), so I'm thinking I'm better off at 0 added fuel at 0% throttle / idle. Any of you guys in the zero elevation with PCV - maybe worth a try.


Edit: I think Dynojet Labs was at 5000 feet elevation, so the stock supplied maps probably work the best at about that altitude.
I'm thinking I might go the Auto-Tune route eventually, but let's see.

I bought the Autotune, just to avoid situations like that finn.
Norway is both at sea level and VERY high mountains...
I'm coming home the 29th, and start testing five minuts later ;-)
