BMW G650X PowerCommander info & experiences (V and III models)

OK, let's start a thread on PowerCommanders used in BMW G650X model bikes. Why? Well, there's some interesting new PC V development taking place right now. For background, the same info and PowerCommanders should apply equally to Xchallenge, Xcountry and Xmoto, as they share an identical Rotax engine, air intake and EFI.


Until now, Dynojet had not developed a dedicated PowerCommander unit for the great but productionwise somewhat short-lived BMW G650X trio. There has been a promise of some sort, even a product code for a PC V unit for these bikes to come for some while, but then time went on and nothing really materialized.

I got fed up. I wanted a PowerCommander for my "Xchallenge R" power-up winter project. So I started contacting people. First the local PC reseller, then the national importer... They knew about the promised product, but didn't know what was the delay. They actually had some orders in, pending, waiting for the actual product... for months.

I then contacted Dynojet Research directly, got prompt and friendly responses, and got more information on the whole deal. OK, so they had had an Xchallenge in once, made some measurements, and noticed that it was a bit more complicated than your regular EFI bike, in some respects. (Me: It's a BWM, complication on simple matters is their bread and butter.)

As I knew that there were positive reports on PC III USB model from F650GS/Dakar Rotax being retrofitted to G650X's, I thought Dynojet should not be very far off their target with the PC V. I enquired what would it take to finalise the PC V, maybe using their PC III knowledge background - would a donor bike help things out? They agreed that would be the best option, but they didn't know where to get one. I told them I'll work on the donor bike, there must be a friendly ADVrider with a G650X somewhere near Las Vegas. I mean, I'm just a tad far away from Vegas, here in Finland.

I posted a "donor bike wanted ad" on the G650X threads here on ADV a few weeks back, and within days AZ-Twin stepped up, offering his bike as a donor. Great! So, where are we now: AZ-Twin aka Rob took his bike to Dynojet about a week ago. They did their thang, and Rob got his Xchallenge returned, Dynojet tuned and installed with a PowerCommander V model. Yes! But guess what, Rob has not had time to test ride the PC V'd bike. Man, priorities! Sleep not, eat not. Ride! (I'm sure he'll get into it, and cure some of this cabin fever.)

I hope the rest of us can make some orders soon, as well. There may be some production, stocking, distribution delays, maybe - but they should now have the unit specced. You guys will be the first to know, I'm sure. Meanwhile, if Rob or anyone has some info, experiences, dyno charts, installation pics, wiring, etc. - why don't we post them on this thread. Also, I would gladly gather here also the Power Commander III USB model experiences *with G650X bikes*. I may be able to contribute on the PC III USB as well, I have some info bits gathered, and such a unit in my garage.

When you share your own G650X PC usage, please identify which PowerCommander, G650X model and production year bike you're using, for clarity' sake.

I really do not know what is your problem.
I drive now 18000km with my PC, it was a second hand from
a F650 Dakar 2004.
He reacts to any change in the laptop.

I'm glad you'll share your info HP2. I know there's no problem for the mechanically & eletrically more inclined guys like yourself. The PC III USB can be attached with some wiring modifications, and you can create a custom map for it in the dyno. It works fine, after those modifications, yes.


Not all end-users are as advanced as this, though. It's a problem if you want a plug and play unit, with a ready made map, and don't want to strip into the original wiring. And it may be a problem if you cannot buy it from the local PowerCommander dealer, or the dealer states that they take no responsibility or warranty for a product not specifically made for the bike.

So, I will argue that for the greater end-user market, it's better to have a dedicated & new PC V product, probably for the same price as the III. And, with PC V you get an option to start playing with PC AutoTune, as well...

@Finn,
Oh I understand now.
But you can take the mapping of the F650.
which brings you a rounder engine running and 1.5 horsepower.

And if you don't like go on a Dyno, you have to work with
the Lambda Meter, if you change muffler, air Filter.... other parts.

Sweeeet!

Gotta love a company that will work with someone on the phone,and start a product for a discontinued bike,on the request of a few owners.
I will buy one not only to plug and play on the X,but support a company that cares about riders.Thanks Finn!

Now Rob,,,,,,,,,,,dude,you gotta go for a ride!

Yep, stop playing around with exhausts and racks, get out there and ride. And then hurry back and write.

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!

Fin,

You got another thread around here I am not seeing?

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.

Is that a new Husky headlight and front fender??

No, it's not the posi-taps location. You would have to check and possibly minimally change the position of the actual pulse sensor inside your magneto engine cover. It's a somewhat technically involved process, not too hard though, but would not call it easy either.


EDIT: So, you'd need to check the Pulse generator part and fitment here (part 3, possibly minimally change fitment 16)


parts fiche: http://www.maxbmwmotorcycles.com/fic...aspx?vid=51546 , check 12. Engine Electrics.

It seems a bit technical indeed... I will try to do a few more tests, saw in the Power commander faq that can also be non stable 12v minimal.

I will review connections and leave this procedure as last option as I'm not sure if I can do it my self.

Thank you for the guidance I will keep you posted if I find any improvements.

Cheers
