Ok, Not for sure if this has been covered before but I thought that I would mention it.

While Im sitting idle in the car, Im looking at the MAFT Pro A/F and its reading 16.0, I quicky look at my AEM wideband and its reading 15.3 so Im trying to figure out when tuning which A/F should I work from? they never get any closer but yet they never get any farther apart.

Is there a way to get them to read the same or is this just the way its going to be?

Thanks
Robert

THE AEM signal is feeding that to the MAFT pro. SO the correct one to use is the AEM.

Now with that said.you might need to adjust the voltage curve of the MAFT pro A/F scale if it has that capability (no clue if it does or does not).
