Map sensor would be hooked into the lpg harness. Follow all Vac lines coming off the manifold. I haven’t played with this exact setup so it may not require a map sensor but I’d be surprised if that’s the case.
Your o2 sensor is 0-1v.
If it doesn’t have map input it may just base load off petrol injection timing. They’re actually a very simple system. They take the injection time from the petrol injectors and the lpg ecu uses a formula to calculate the required lpg injector open times based on this.
Just try to auto calibrate and see what happens. I drove my ecotec on just an autocalibrate tune for well over a year with no issues before I set it up for a wideband sensor and tuned it properly.
