I installed my wideband last night (innovative lc-1) and its reading really rich, like 9:1 under full throttle. This is on the stock map that comes with the mspnp9495. Does this seem right? Im not sure i have the wideband configured correctly with the mspnp. I just dont wanna start leaning it out if its not really that rich and its just a misconfiguration. Sorry if this doesnt make any sense, im running on just a couple hours of sleep.

Thanks in advance

You gotta change the lamda sensor in the configurator to LC-1 0-5v 10-20:1AFR

And you have to change the LC-1's own programming to match this; its default is a little different.

"while the LC-1 will use the INNOVATE_LC1_DEFAULT settings if you have not changed its outputs. Note that the DIYAutoTune.com products and many others have programmable outputs, and these options are simply for the default configuration. Adjusting the LM1 to use a wider range of output voltages, such as setting it to give 0 volts at 10:1 AFR and 5 volts at 20:1 AFR, will reduce the effects of noise in the input. This is recommended for best performance though you will need to program your LC-1 or LM-1 outputs to match, that’s easy though. Once you have specified the wideband settings, go to the File menu and select Save. Then you can run MegaTune and have it display the correct air-fuel ratio."

I thought that meant that the default would match up to the default on the LC1?

Matt Cramer

The Innovate LC-1 default setting should match the brown wire's output. However, I've had enough users claim that the 10-20 setting gives more accurate results that using the o volts at 10:1 and 5 at 20:1 is our standard recommendation.

12.5 sounds about right.
