Hello everyone and thanks ahead of time for replies, evn the sarcastic ones! I would like to know which exact kit would be best for my GEN II setup for A/F tracking. Would just the Lm1 or LC1 cables work? Could I buy that and then get a sensor from the junkyard to save money? Which sensor/part number compatable with adapter cables to GEN II? Any help appreciated! I need a wideband set up yesterday, I just can't afford $200 to $300 bucks, and do I need a datalogger with it? Or anything else for that matter? Should cable and O2 work with Gen II without other parts. I have looked for this information, and I'm sure it's availible somewhere, apparently I'm to dimwitted to understand. PLEASE HELP! Car runs run. Thanks again, John.
