We have just received some advanced information today regarding the O2 Eliminators.

Please read below.

DynoJet have stopped making them as they have realised that according to them this 02 eliminator does not work on the 07 & 08 bikes with the lambda probe. He told me that now all PCIII for the 07 and 08 models comes with a warning that people must just disconnect the Lambda probe and not map the fuelling around the 2K mark (I think he means the rev rage of 2000 revs) The fault comes not from the Lambda but from the ECU fitted to the 07 & 08 bikes which causes them to surge. DynoJet has reported this fault to Yamaha and they think that Yamaha might reprogramme the ECU's to rectify the problem, however Simon doesn't think they will do and suggest that all Dyno testers must keep this in mind when designing a map for these range of bikes.

Freez & myself will carry out some tests soon. If the O2 Eliminator is not at fault, I cant see why they no longer what to fit them. I know the software is not right in my 07 model, I reported this on my last dyno run as I can't get my air/fuel ratio perfect in lower rpms. It is not bad I would say 95% perfect.

We will amend the necessary threads relating to this O2 Eliminator.
