I am in the process of doing the pinouts to utilize an OBD1 AEM EMS in my OBD0 wired race car. I noticed there is no provision in the OBD1 wiring for the PA (atmospheric pressure) sensor from OBD0. Was this sensor not utilized in OBD1?

Thanks!

On most US ecu's, the PA sensor is internal to the ECU. For most other countries, the PA is not utilized.

If you build the harness correctly, you will be ok. I know on the pre-OBD (OBD0) chassis' the PA sensor is external and I have had to wire them into harnesses many times. If you have issues, post them up and we can help.

Thanks guys!

This is a chassis without AC/lights/IACV/etc, so hopefully I wont have issues. The EMS seems versitile enough to deal with this. If I have an issue, I will let you know.
