The stock 3.2 flat 6 in the car has PMO carbs and was originally set-up by Bob Watson about 9 years ago...
I have tweaked the carbs over time using a simple synchro meter to get the choke balances all the same and that has worked well, but is there more, and this is the point of this thread.
I don't want to fuss with rolling roads, I'm not good enough at driving this thing to be splitting hairs, just want a good weekend on the hills.
The engine last year was 'popping' more than is normal, so will check for air leaks on the induction/exhaust side before checking balance, BUT, the ex manifolds have ports for a lambda sensor which Bob used to set the mixture. The senders are just after where the (custom made) individual pipes merge to 1 larger tube before the large silencers. The exhaust pipes are NOT merged, each bank goes 3 into one into a silencer.
Is there anything to be gained to have sensors in these ports for checking mixture, and if so, is there any kit any can recommend that would do this job (and be worth it?).
The ignition is a simple coil and contact breaker, absolutely nothing special.
