Randall,
I must have missed the fact that the discussion was only talking about
setting the idle.
I have two widebands and I tune a lot of turbo'd and supercharged cars
and they are indispensable.
I only have two Triumph customers and one of them was quite happy with
with his own tune on his carbs,
I finally persuaded him to let me use my wideband and he could see for
himself how far off his wot a/f ratio was.
His a/f was between 17:1 and 18:1 and he thought the car ran just fine,
we did a lot of tuning and brought that down
to about 12.5:1 and he went from 115 SAE hp to 142 hp at the wheels.
Since then we've put a set of webers on and it feels
even better, we'll re-dyno soon.
Anyway, I feel some of you more serious racers could benefit from this
technology.
Thanks
Ron
