Wideband controller, narrowband emulation

[Prodigy]

I've heard the innovative have some issues, first is they require a very very specific ground connection (no real issue) but the thing that troubled me is the O2 sensor needs to be zeroed everytime the car is turned back on. I'm not sure if they currently have these issues, but a friend o mine had an older on, and everytime he went to start the car the system wanted the sensor calibrated, not bad for him (turbo crx) but for one of us.... A much greater hassel....

I'm not sure I follow. Every wide band has a startup routine (whether you're made aware of it or not is another matter). It's the nature of the beast. The probe needs to heat the probe before getting accurate readings.

Calibration of the probe doesn't happen until you push the button to calibrate it.

In another way to look at it, where the narrow band is a passive sensor, where the wide band is an active sensor.

My friends wideband it required him to remove the sensor from the exhuast, hold it in atmosphere, for it to zero, then reinstall into the manifold...

I know there is the start up heat cycle for them (about 5-8 seconds I believe) that's no biggie, my friend removed his from the mani before each start up... It sounds weird... But that's what he did... Now mind you, he could have been acting really really stupid and doing that for the calibration sequence, which would make him a complete tard... It could have been misinturpitating the instructions...
