vtvette Posted June 27, 2020 Report Share Posted June 27, 2020 Hi all, preparing my 1990 300zx twinturbo for install of a G4x plug/play ECU and Link MXG 7" Strada display. The car has a two wire VSS that outputs an AC sign wave signal from the VSS to the factory cluster, then the cluster converts the signal to a digital speed signal that is outputted to the ECU via a single wire. Since I'm ditching the factory cluster for a driver display how would I go about getting a VSS signal to the Link G4x ECU? I assume the Link ECU will be looking for a single wire sending a digital signal like in the stock configuration? I've searched around but haven't really found much about this issue. Any help would be appreciated thanks. Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 27, 2020 Report Share Posted June 27, 2020 The ECU will take a AC/VR sensor directly, connect one side of the sensor to sensor ground and the other side to a DI. It may not work at very low speeds due to the low voltage output but they will usually work from about 10kmh and up. Quote Link to comment Share on other sites More sharing options...
