I am currently datalogging my wideband o2 sensor thru the ac press.
Wideband o2 values show up in terms of ac pressure (when reading datalogs from datamaster).

I then have to convert it, using a linear conversion, to afr.

I am getting tired of converting it. Especially when i am being charged for my time on the dyno. This is an extra step and it slows me down.

I want to use datamasters 'custom data' function to have it show me afr. In order to do this, i need to know the 'byte #' in the code, that ac pressure is displayed on

Does anyone know what byte # is used for the a/c pressure?
