Default Having some issues with tuning 02 sensor off

Ok guys I just everything set up mspnp2 with aem 30-4100 wideband, everything is hooked up right but the 02 sensor is reading a unit higher than the wideband is. I have my propertiers for the afr table 0v=10afr 4.95v=19.9afr. it idles at 250rpms, struggles when leaving a stoplight. Right now I cant get it to start, I have the battery charging but I don't know what to do.

Thanks in advance guys

Have you input your values to megasquirt with the curve differences or whatever that thing that you have to do with all AEM widebands?

Is your install done properly?

I calibrated in the input voltages and the install should be done right since its plug and play lol.

I was unaware that there were PNP wideband setups available for Miatas.

My mistake.

Carry on.

I have learned that Plug And Play is like the word "Indestructible", there is always room to F something up. where did you choose to ground the WB.?

well I got it started with the change of the idle controller I had it on/off instead of pwm 2 wire. It idles really high though, then after it warms up and I restart it the idle goes really low but I can't figure out how to control it
