HEGO

Thanks for the advice on the use of HEGO sensors.

If you reckon that they are still not heated enough unless placed somewhere
in the manifold what would be you're advice for a V8 application - two
sensors, one in each manifold used simulatneously or one sensor that's
switched between the manifolds. What sort of accuracy would I be likely to
expect if I was to place the sensor in the collector?

You're right in saying that there is a factory efi application for this
engine (Rover V8) - it's a Lucas model but the poeple with the most success
that I've heard of is JE Engineering. They've done a lot of work on both
single and twin plenum systems as well as developing engines for use in Rally
Raids.

If anyone's got any questions about Lucas systems then let me know as I'm
shortly going to be spending some time in their factory so I should be in a
good position to ask.

Regards,

Dave
