I just switch from narrow band to a LC1 Wideband. I went under setting and "set the innovate 0-5v". I am confused exactly what each of the setting do under exhaust gas settings.
Is the switch point the point for 14.7/1 stoich?
controller authority?
How do i get my 02 gauge in Megatune to read correctly. It stays in the red all the time.
For the programmably output i have the o2 sensor set for 2 volts at .5 And 4 volts at 1.5 Which should land stoich 1 at 2.5 volts. Is this correct?
thanks for the help

First of all, go to the MegaTune configurator and set the lambda to WB LC-1 0-5V or something like that.
Then programm you LC-1 to get values from 0-5V. The stochio 14.7:1 is 2.45V then.
Use 2.45V as the switch point. This is lambda = 1 - your cat. conv. works fine at lambda = 1.
Then you can set the GEGO correction within the exhaust gas settings. The authority is the range in wich your ECU can modify the injected fuel to get the AFR to 14.7. You should use a minimum of 200 ignitions per step. Otherwise the engine will run fast and slow and fast and ...
In addition to that you should set the controller step size to 1 and the authority to 50.
Active above coolant is the water temperature threshold above wich the GEGO correction starts working. Active above RPM should be clear

I hope this helps
