Power commander lambda question

[Offtheclockuk]

Hello fellow strommers,

I scored a 2nd hand pcv off ebay and have fitted it as per the instructions (with no mention of the lambda)

As per title I'm confused as to what the procedure should be.

There are posts across a couple of forums that suggest the lambda should be disconnected, and certain pins pulled from the ecu plug.

So I have a couple of questions..... why would the lambda have to be out of the system if dynojet don't mention it?

And what magical pin would make the lambda fault not be registered?
 considering I faffed about a couple of weeks ago struggling to find a solution to my lambda less exhaust from the states (which I gave in on and got a bung welded in)

Annnnnnd as it's Friday...... and I'm feeling cheeky, one more question.

Anyone with a power commander got any decent maps I can try out now I've fitted it haha

My bikes a 2002 VEE if it makes and difference.

As far as I know US Vees did not have an O2 sensor, so PCs were originally set up without having to work with one. Dynojet recommend disabling the O2 sensor and their maps for UK bikes take this into account. There are several maps for UK bikes on their web site and as a starting point you might try using one of these which most closely matches your bike exhaust and air filter wise. Ideally the bike should be set up on a dyno to get the fuelling spot on.
        To disable the O2 sensor you can either disconnect it and fit a proper blanking plug if you can get one or make one yourself. I think it uses a specific value resistor if you can find out what value to use. Alternatively you can unplug the sensor and then unplug a pin in the ECU to stop an FI error being generated. The early Vees used a different ECU from the later ones and I don't know which one to unplug, but will have a look through my paper work and see what I can find.

Cool, thanks

Search O2 eliminator. They plug into the loom in leu of the lambda sensor

[Offtheclockuk]

No o2 eliminators available for the 1000, I've already checked and even asked a couple of eBay vendors to see if they could get them.

I never managed to find an O2  blanking plug for my Vee so had to disconnect it and unplug a pin in the ECU. Re. which pin to disconnect in the ECU after unplugging the O2 sensor. If you have the ECU with the single connector (later ones have two), then looking at the ECU with the connecting slots/lugs at the top you need to unplug pin 23, located on the bottom row on the left. This should be black wire with a white tracer. This info comes from Dynojet in the US and may not be correct due to model variations and the like. You could unplug the O2 sensor and see if the FI message comes up on the dash and the disconnect the pin as above and see what happens... Best of luck.

Something like this?

OK, no worries blokes.
I thought they were quite a generic fitment.

That's the pic! Just hope it's the right one for your bike.

Sheesh I wish they were haha it would be so much easier!

I'll have a look after work tomorrow and see if it relates to my bike, I'm sure there is only one big plug on the ecu so it can't be too hard to work out

Pin is out and lambda is disconnected, as yet no errors, I'll be sure to mention it if the light comes on in the future haha

Well done! Hope the PC does what you want....

Already feels less harsh and much happier through the rev range,
A local dynojet dealer has quoted £140 for a custom map so I might give that a shot after Christmas.
