Freez,

The way it happened is like this, last Friday, I was talking to Simon Cope, owners of Carbon Cans Co., who is also an authorized retailer for DynoJet products, he has a dyno test machine in his workshop to tune his new cans to all different bikes, furthermore he was trained by dynojet officially with diploma et all.

However Simon told me that he wanted me to remove the advert to the O2 eliminator from our website because he was told by DynoJet that they will not be shipping these as they found them not to be working for the 07/08 models of the Yamaha XT660X/R.

The tests done to these bikes with the 02 eliminator and a PCIII showed no improvement in the surging issue of the 07/08 models and this problem is directly related to the ECU of these bikes which has proven to be incorrectly mapped.

For that reason DynoJet have told Simon that all new PCIII sold for the 07/08 model will have a warning label telling people simply to disconect the Lambda Probe, and not map the fuelling at the 2K range which seem to be the best compromise for the time being.

DynoJet will wait until Yamaha finds a solution to the erratic mapping issue with their ECU before they will re-introduce the distribution of the 02 eliminator.

So for the time being the ball is entirely in Yamaha's court.

For the exact same reasons, Kev has decided also not sell his 02 eliminator until a viable solution to this problem is found by Yamaha.

Rest assured that Kev will enquire with Yamaha, and he believes that if they've succesfully remapped the 04-06 ECU's that there should be no reason for it to be done to the new bikes too.
