Innovate MTX-L and Datalogit Matching AFR's ? Help
Hi
just after some help setting up the offset voltages
Im trying to log my AFR's on the Datalogit
now i just cant get the data on the gauge to match what im getting on the datalogit watch screen.
what i want to know is how can i match up them both in the instruction Manuel it states:
4 Wiring Analog Outputs
The analog outputs on the MTX-L are ‘single ended’. That is, each output uses just one
wire. It is assumed that the MTX-L and the device it is being connected to are already
sharing the same ‘ground’. In a vehicle, this is generally true, but there can be small
offsets in voltage when devices are grounded to, say, the chassis at different points.
You can minimize these offsets by sharing a good, common ground point, or you can
adjust for them by configuring the analog output voltages on the MTX-L.
How do i do the above please.
the car is a FD3s RX7
thanks

run a wire from AN2 on the Datalogit to the ground point for the MTX-L. Then use the Delta AN1 - AN2 features in the DL. Do a search on this. Also, check out this thread I made a long time ago https://www.rx7club.com/power-fc-forum-47/my-power-fc-lc-1-xd-16-datalogit-wiring-diagram-707298/ .
