Output simultaneously ? Every time the digital output is connected to the dpi signal wire on the haltech io box the gauge loses signal and shows E-- which means gauge is disconnected.
Before someone asks I am using the digital output because it provides fuel temp and e85 content which makes the sensor more accurate. I do not want to use the analog output for this exact reason.
