Hello team, I was configuring my g4+ pnp last week. Tried to connect AEM x-series wideband to ecu(through CAN). Everything is good at first, than suddenly I lost my tacho signal. It was strange because ecu still have normal rpm signal. Only instrument cluster and hks evc(can read TPS) lost it. Here is my troubleshooting attempt: 1.Restart engine 2.Restart aux function 4 (tacho) 3.Adjust tacho duty cycle (25% and 75%) 4.Reload base map 5.Downgrade firmware But I have no luck to solve this problem. If I change back to OEM ecu than cluster and evc will back online, so it shouldn’t be a wiring problem. Do I have something else worth to try? Any help will be appreciated.
