" From: Tom Jennings <tomj@xxxxxxx> " " " The page for that new-fangled thing does say it likes a " wide-range O2 sensor. Even the Holley Projection or whatever it's " called stuff says it works better with feedback from the motor " (O2, etc). Most of the bad rep from the Holley etc I notice " are from NOT using feedback -- hence it's totally dependent " on finely tuned maps, which would have to change with tempo, " altitude, air density durin rain, etc making them a total pain " for daily drivers. which is why open-loop efi systems had all sorts of sensors - for everything -but- humidity afaik - in order to predict the right amount of fuel for the air. the all-mechanical bosch k-jetronic [odd name] throttled fuel flow with an ingeneous paddle in the airstream that reacted to air mass flow. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
