I started tuning the car this week with the wide band. First off, all I can say is the wide band is the ONLY way to go...I started with the narrow band and made fair progress in cruising but WOT was a major challange. Since switching to WB it's been 10 fold easier. (69 camaro 461, headers, Lunati Bracket II cam, TKO-600 w3.70s, And Holley 950 commander TBI 75lb injectors w/WB O2).
Anyways I was wondering what and how others go about tuning. So far it seems to run best at 13.2 at WOT and partial throttle. And 14.0-14.7 for cruising. All seems good, except I still need some work on the "accellerator Pump".
1) Do these readings seem to fall in the normal range?
2) How lean can you safely go when cruising (fuel milage) ?
3) When working on the Accell Enrichment do you try to maintain 13.2(?) or should you see a rich spike as you hit the throttle?
4) Any other tips?
Thanks
Chris
