Hey does anyone have any experience with those rich/lean indicators by edelbrock or msd or Holley. i know the wide band ones are preffered but do the narrow band ones get the job done??

The narrow band units are not as good to use on a performance engine. You can get wide band units from companies like Innovate pretty cheap now.

Narrow band indicators are only good for near stoichiometric mixtures. Even a well tuned 1st gen carberated engine is likely to run on the rich side of stoich. So IMHO, don't waste your money. Wide band is the way to go.

Its unfortunate OE ECU/ECM's are not programmed for wideband sensors. Tech @ BG, Welcome aboard! Word gets out, you'll be swamped with questions.

Everett,

Thanks, we try to monitor as many boards as possible.
