Lambda Sensor Resistor Query

[Griffo]

This is a bit of a random query I know, but it does relate to motors, or at least the lovely gas that comes out the back end.

My '08 SV650 is having an Akrapovic exhaust plonked on at Suzuki (which means cutting a pipe meaning O2 sensor is lost), however they've just called to say that the '08 model runs double the voltage through the oxygen sensor compared to the '07 and nobody they've contacted seems able to provide a resistor to attach to the cable to stop the ECU throwing an error.

I've already posted on the owners forum, but thought i'd try here, I dare say people have had similar problems with cars too. Is there a way to work out the resistor needed and do it that way, electronics-shop style? The garage guy thinks fuelling may get messed up if we leave it, which I'm hoping would only be when cold, but unsure. Either way, any suggestions pint-buyingly received!

I think it is (or was) just the heater circuit, as this resistor method worked on the '07 version. I'm trying to get in touch with a guy at a tuner place at the moment to see if they've found a way round it.

Welding does look like the best option, though Suzuki can't do that for me.

Yeah thanks, it does sound like the best bet, but I'm not sure what sort of place would do that. I don't want some backstreet garage messing it up and the world ending.
