Yes, another wideband voltage offset reading weird..
 

I'll try to keep it short..
Aem gauge is getting signal and sends the reading to the actual gauge. Tunerstudio is getting signal. I've had to adjust the calibrated voltage reading outside the numbers that come in the aem manual. Something like .5v=8.5 and 4.5v=18 is the manual instructions. I have it custom for .5=8.3 and 4.5=17.8. This is as close as I can get it to match but this is what is annoying about it.. it reads very close to the actual except tunerstudio afr bounces in between some afrs when constant on the gauge. Like I'm driving at 15.1 afr on gauge well tunerstudio reading is oscillating from 14.9-15.1 afr very rapidly and sometimes it will stay still but more often than not it won't sit at matching afr. At first I accepted this and tbh I really didn't think it would matter but now that I'm learning more about tuning and actually tuning my car it's something that i want to try to fix. Last thing is that in tunerstudio the wideband voltage reading is never dead still even if the gauge is being still. It'll bounce 1.84v plus or minus .02 volts that is just an example. I have the wideband powered to the appropriate wiring through a add a fuse on the fuse box under dash and the grounds are on the options port if the mspnp2. Is there any way I can attempt to fix this or just live with it and maybe just go with the recommended numbers from aem and see if it sits still? I know the recommendation aem gives makes the afr read around .2 leaner on TS. I just want a non bouncy afr signal on TS.. sorry that was long.. advice?
