Finally got the wideband A/F guage installed in 'the Bird.' In addition to a general curiosity, my motivation was a conviction that the Weber DGV on the car is not jetted properly, and surprise, surprise, that is in fact the case. Kinda cool to see what's going on at various rpms, loads, etc. Idle is too rich and everywhere else it's actually running very lean except when I stomp down and get the secondary to open up and even then it seems a bit lean still. Anyone on the board who has an A/F guage installed have target ratio recommendations? I've got a general idea from some articles a search turned up, but someone who's BTDT with a B20 would be good to hear from. And a source for Weber jets (maybe I'll send for IPD's jetting kit)? Eventually SUs are going back on the car, but in the meantime I'd like to get the Weber dialed in right.

Thanks!
