Using this on my car as analog. Im running positive and negative both to the analog outputs to hpt
Right now in on resistor calibrate (auto calibrate). When its calibrated it reads 19.9 but hptuners reads 17.9.
Running the cars it doesn't really switch much from 15 to 17 afr on the scanner even with command changes and by the smell of it is def not lean, the guage also reads .5 to 2.5 even tho set up for AFR.
My next step is maybe to do a free air calibration.
Anybody have experiences with this.
Also should i have run my anolog positive from the gauge and then the negative to a dedicated ground or back to the gauge analog negative?
