power commander v on a 2007 (k7) DL1000

[theron1323]

I have just bought a power commander v to fit on my 2007 DL1000 which has a K&N air filter and Delkevic exhaust.

The exhaust has two modes; baffles in and out,  and I can use  pcV maps for both configurations  and improve low speed running.

Do I need to bypass the O2 sensor?   and if so what is the best method of doing so?

I have done a  bit of web searching and as far as I can see all the quick fix bypass bits don't work for the k7.

cheers

Head over to INTRODUCTIONS and say hello. People may be more willing to help you if they know who you are.

Hi,  
Yes you do have to disconnect the O2 sensor but this will throw up a fault and your Fi light will be on constantly . To disable this you have to cut a wire going to the ECU. Your ECU (located next to the battery) has two block connectors one large and one small, you need to cut the black wire with a white stripe on the smaller block , this will turn out the Fi light just for the O2 sensor .

[theron1323]

Thanks for your help... wire cutters in hand....I'm going in!..

I will report back on the progress of installing and using the PCv

 

[hookie]

Hope this is not too late but you don't need to cut the ECU wire. Once you've unplugged the connector from the ECU, remove the cover going over ther connector pins and you can then, using a very small screwdriver,push the little tags in on the pin and then pull it out out of the back of the connector.

hello

 struggling to find the right wire to disconnect on ecu to turn off O2 sensor... I have 4 wires that are black with a white stripe... all appear to be earth wires...

[hookie]

There are at least two different wiring layouts used on DL1000s. The data sheet from Dynojet says to disconnect pin 17 ( black with brown tracer) on the small ECU plug. My bike (2007 Vee) had no wire like this and after much rummaging around I was told to try pin 11 (black and white tracer) on the small connector. If neither of these is right for your bike you'll need to do some more research on the internet and perhaps contact some professional installers and Dynojet UK direct. The pin numbers are marked on the connector so should be easy to locate and count up, but if my memory serves me correctly the data sheet from Dynojet had the pin numbers back to front! If you need this sheet PM me and I'll send it to you.

[Juvecu]

Don't cut the wire either, you can release the pin catches and just push the pin out and tape it up properly. That way you can try both 17 and 11 and see which one is the right one.

Thanks all

I  will investigate further.. the workshop manual wiring diagram for the  fuel injection system is, I think,  different for the K7 model...
 
I can put up with the warning light for a while and so I carried on with the installation.

So far I have  installed the PCV,  a 12V dc switch to run two maps and disconnected the O2 sensor.

After loading maps 503 and 504 (European maps for aftermarket exhaust and K&N filter)  I tested the bike..

The results are impressive... the machine runs much better at low revs and speed;  I can now ride in 3rd at 30mph! Hunting and stumbling  are gone and no more backfires through the carburettor(in baffles out mode). This will make commuting in traffic much easier.

Obviously its early days, as I get more used to the system I can tweak the maps accordingly, I also know that   someone is mapping a Delkevic exhaust system on a DL1000 in the US so better maps may be available, or I may just save up and get it mapped at a dynojet place as recommended by a friend and  people on this thread.

But for now it seems to work well... I will report back as I use the bike more and can check on mpg and long term performance..

 

[Juvecu]

Just so you're aware, your bike doesn't have a carburettor   I assume you meant throttle bodies

[theron1323]

whoops!

you are quite right Juvecu... I don't have carbs...

[Juvecu]

I was just being my pedantic self, although, if I didn't do it someone else might've anyway

I am about to bite the bullet on a power commander.  My local dynojet dealer are quoting £299 for power commander (inc fitting) and £159 for custom map.

My thinking is:
1.  Want to avoid future issues with French fuel (previously had  lumpy low speed issues on French fuel)
2.  Seems recommended for optimum running, the bikes a keeper and planning to ride to Romania next year - don't know how good the fuel is there

Sensible plan and price?

[hookie]

The custom map will really only be right for your bike and broadly speaking UK fuels. In France the choice of petrols in most stations is 95 and 98 octane. The cheapest places to buy fuels, often by quite a margin, are the supermarkets where it can be as much as 15-20 Centimes a litre cheaper than dedicated fuel stations. My Vee (2007 with a PC etc.) runs fine on both 95 and 98. There is said to be a benefit in using the 98 octane stuff more in better mileage rather than running but I'm not convinced. You will find in some stations that they have 95 octane E10 (10% alcohol) which is a bit cheaper, either as well as normal 95 but sometimes only the E10 is available. I've used this when it was the only fuel available and found it OK. I can't comment on fuels in Romania, but if they have recognised brands these may be the best ones to use.

[temporaryescapee]

Thanks Hookie - did you notice a difference with you fitted your PC?

We have the same bike/model year.  I had real issues on a couple of trips that immediately went on fill ups on leaving France.  Switching to 98 once the problem was there did not seem to sort it.  Since then I have used only 98 and tried to avoid supermarket fuel.  Doing this I have had no issues on my last 2 trips.

My knowledge is VERY limited but I am thinking the bike runs lean at low revs (emissions) and anything less that pukka fuel shows up the lack of margin in the fuelling.  Of course this could be total cobblers.......

[hookie]

I never found the low running fuelling a problem, more a bit annoying really. First thing I fitted was a timing retard eliminator (TRE) and this definitely improved things and made the bike feel a bit sharper as well. Next things were a BMC air filter (very similar to a K&N) and a pair of slightly baffled exhaust cans. These may have made a small difference but probably only a little. I didn't find French petrol made things better or worse regardless of type or brand. I fitted a Power Commander 3 USB mainly to try and improve the rather abysmal fuel consumption which has always been in the very low 40s to the gallon, even if ridden very gently. I used a PC map off the Dynojet web site that most nearly matched miy bike, which contrary to the widely held view actaully weakened the low end mixture off and the bike now runs noticeably better low down and will chug along happily in towns at 2000 rpm in 3rd or 4th gear, something it didn't do too well before. Running the engine hard at high revs also feels better and it definitely accelerates quicker. Fuel consumption has improved by a few m.p.g. and I think the mixture can be further weakend off, although I haven't had time to try this as yet. The reason I thought it was running rich was that the baffles in the exhaust cans were always very black to the point of being sooty. Since fitting the PC it is less black but still more than I would expect. Overall fitting the PC, once I sorted out how to disable the oxygen sensor, has been well worth doing.

Another fan of the power commander here. I went down the same route as Hookie, TRE, decent air filter, open cans, power commander. I started off with a map off the dynojet site but the best way without a doubt is the custom map route. I had mine done at Dynobike Malton highly recommended.

MPG improved 45mpg+ riding sensibly, 25mpg ragging it.

[tallpaul]

Rochdale Hornet has a G.I.Pro gear position indicator on his vee that also does TRE . Will a power commander work with that?

[TLPower]

Yes it will. TRE alters the gear position signal, the go pro shows which gear it's in, Power Commander allows the fuel map to be altered.
