Capt,

I have to agree with Freez's earlier post on this subject. Mine is running much much better with the lamdba disconnected as when its connected it appears to be fighting between the YAM engine mgmt system and the PC3.

However, in a PM to Kev i will await the true experts advice on this. I have emailed Dyno-Jet UK directly on this subject as i know one of the main men there, so hopefully we can try to understand the issue and lets see that if its a YAM problemo that they look to remap their s/w

Fingers crossed one and all.

Cheers

WB
