I fitted the PC to my 1999, had it set, twice, and did many miles with it. Then I learned of the 'better' version, designed for the GS, that would perfectly tune each pot, but required an O2 sensor in each downpipe. New PC unit ordered from USA, import tax paid; spare downpipes purchased and Lambda ports welded in. Change of circumstances and hobby work stopped.
Modified downpipes sold.
I am left with the original Power Commander harness, original paperwork and box, but missing the PC Lambda sensor for it. 1997-2004 version.
Also have the new, never taken out of the box, GS version, which in the right hands, will offer the best improvement for fine tuning the engine management system on any 259 engine, so I was told.
The chap that does these best is in Peterborough, small business, does a lot of race tuning, always busy.
I am selling it all now; these two kits for £

and the pipes that were altered, now sold, showing the Lambda ports

Any chance of speaking with you to make sure I have read your listing correctly please?

I guess you are referring to BSD. Bob I have not seen wide band Lambda sensors for sale so you may have to get in touch with Dynojet for that.

Yes it is : http://bsd.uk.com

Very helpful, very busy!

Might have misunderstood, but if you're after replacing the lambda sensor in the Power Commander kit, I used the following:

Bosch wideband oxygen sensor LSU 4.2 7206/7366

I think variants of the above come with different cable lengths etc. but the above part was a direct equivalent - I have the additional Dynojet a/f gauge and it works that just fine.

Cheapest I found in (back in 2012) was EFI-parts.co.uk £66.98 delivered

Apologies if I'm off track with this suggestion. All the best
