Hello, We are running a B58 engine on an EMU PRO 8 with GDI. We are experiencing an issue where the engine suddenly turns off. When this happens, all logged values freeze and the engine shuts down. There is no issue with power supply. I have attached logs showing when the problem occurred. Shut Do…

Hello The WDT Reset causes the engine to stop. We will address this issue no earlier than January 7, as we are currently on a holiday break.

Hello, As Norbert mentioned, the watchdog reset has caused the ECU to reset. This should not happen. We consider this to be a software issue. Please tell us more: Are you using the B58 basemap provided by ECUMASTER? How many times has this issue occurred?

Yes, I’m using a basemap. Sometimes it shuts down immediately, and other times it shuts down randomly after 5 minutes, 10 minutes, or even 20 minutes.

We developed the B58 basemap on the PRO-16 model (using only three connectors), and we didn’t encounter any reset issues. Today, we will test the engine on the PRO-8 model. I will keep you posted.

I’m sending new logs from a cold start. The engine shut down four times during startup. 4x shut down on cold.emuprolog (639.2 KB)
