Narrowband calibration in TS

Post by evo828 »

Ive updated FW in my MSIIE to the rel 2.1.0. I've done all calibrations in TS - however it doesnot seem to be correct (in log only values 0.174 and 0.390 V ) are appearing. Then I did narrowband calibration in MT - after that the logs are showing correct values between 0.1 - 0.95 V.

You know I didn't realize the O2 that is data logged is actually reverse engineered from AFR on MS2.. But I looked in the The formula I have in there for Narrowband would cause this. I'll have to change this.

Thanks for the heads up.

I don't remember anymore why I was using this formula for Narrowband in the ms2ReferenceTables.ini file but this is what was in there:

adcValue > 92 ? 12.5 : 16.9

The correct formula should be:

100.0 * (1.0 - adcValue * 5.0/1024)

So the Narrowband entry should read:

solution = "Narrowband", { 100.0 * (1.0 - adcValue * 5.0/1024) } ;



It is updated for the next release.
