UVic Formula Racing Posted March 26, 2023 Report Share Posted March 26, 2023 Hi, Our FSAE team recently switched to a FuryX from a Thunder and are working on setting it up but have run into a strange issue. I've included two screenshots, one is the old ECU with a custom PDU, the other is the new ECU with a ECUmaster PMU16, in both setups the message to turn on the pump was done through CAN. With the new ECU, when the start button is pressed there is a delay before the engine starts spinning and then the fuel pump is turned on after cranking is started. This also results in the ECU giving a massive pulsewidth on the crank enrichment since the fuel pressure is non-existent. On our old ECU it's clearly visible that the fuel pump is turned on as soon as the start button is pressed and then the engine starts cranking a bit later.
