Wideband calibration
I posted this over on the adaptronic board but they are a little slower than you guys.
Basically the adaptronic has a fixed calibration table for using the analog (0-5V) WBO2 sensor and it doesn't match the calibration sheet that came with the AEM Wideband (w/o guage).
AFR
Adap | AEM | Volts
10.00 | 08.41 | 0.00
20.00 | 19.44 | 5.00
12.00 | 10.60 | 1.00 (Interpolated)
My question is will I be okay mapping the AEM calibration to Adaptronic values?
Example:
If I want to run an AFR of 10.6 on the AEM, I would enter 12.0 (1V on both calibrations) Adaptronic AFR table.
Does anyone see any issue with this?

I can't change the output values, that is the problem.
Let me see if I can clarify:
AEM reads AFR of 10.6 which is 1V -> Adaptronic sees 1V and thinks 12.0. If I need 10.6 then car blows up, right?
or conversely
I enter 10.6 into Adaptronic AFR table (~0.25V)
0.25V on AEM calibration is 9.0 AFR so I get way more fuel than I want.
So is there any reason I can't just manually do the conversion between the 2 tables so I can get the AFR I want?

Just to verify, you have UEGO selected in Oxygen Sensor Type on the Analogue tab, AEM UEGO selected in the Second Serial Port of the Special Functions tab and 254 for Parameter 1 and 253 for Parameter 2?
My AEM gauge reads exactly what the WARI gauge reads when I have the Adaptronic gauges window open in WARI.

I have the old version w/o gauge or serial, so I'm stuck with 0-5V analogue only. I don't think the serial port settings have any affect on the analogue UEGO.
I think I'll be ok, as long as I remember the AFR in the table isn't the AFR I'm actually running. I was just hoping for some confirmation. I guess since it will always be richer than entered the worst it could do is kill the cat/sensor.
