Wideband controller, narrowband emulation

[vex]

I'm going to put that on your friend then. You don't need to calibrate the sensor every time you start the car. That's just redundant. You only 'need' to calibrate the sensor if and only if you have a suspicion that the sensor is no longer in spec.

Furthermore to calibrate the sensor (if you have it in a proper location) you won't need to pull the sensor. Think of it this way: don't try to calibrate the sensor while the exhaust stream is going over it as that will skew the result, but if the car is off there is no exhaust going over the sensor and if it's been off for awhile any and all exhaust gases there were retained in the exhaust system have long since seeped out and been replaced with regular 'old' air.

Honestly, the LC-1 is your best bet. Though if you have an RTek you don't need a narrowband. You can tune with the wide band and get your fuel mixtures where you want without having to go into closed loop (the benefits of tuning).
