Thanks for the info I'd map it on the road using my wideband lambda gear, like i do my existing stuff. I can't quite see how a road car will map well with out a TPS. There are far different fuelling and advane requirements at 10psi part throttle than 10psi full throttle. Can u shed any light on this?

How does the wideband work? Is it closed loop? Can it revert to the map after certain loads/speeds? Also, does it hunt for lambda 1, or can u set it different target afr depending on load?

Rick.
