I was going to buy a Gunson recently. They're cheap enough on Ebay.

However, the specs rate them as accurate to +/- 0.5%. Which, uhhh, doesn't strike me as very accurate. Might be OK if they were at least consistant and you got a comparison with a professional 4 or 5 gas analyser so you knew where yours was at.

My understanding was that idle setting has less and less influence on overall mixture the further you get from idle on a regular CIS car. It does influence running up to about 3,000 RPM - but almost no effect on WOT. By the time you put boost and enrichment into the picture, that's a whole different ball of wax.
'77 S with '78 930 power and a few other things.
