Got a question from a new user of the display, he is seeing some "ECU Comm errors" when he connects it to the I/O board (with the red/yellow/green LED), and the display shows no info.
He reports that the GSU works ok when connected to the I/O board.
A couple of notes:
1) The GSU communicates with the ECU using another "com port" than the JetCat Info Display. The GSU uses a I2C bus, and the info display uses a async bus, so even if the GSU works, this is no guarantee that the info display will too
2) Be sure that the "GPS setting in the ECU" (Turbine limits -> GPS Receiver") is NOT set to "COM1", if it is, then the ECU expects a GPS receiver on the async port, and it wont talk to the info display. The correct setting for the GPS receiver is "COM2" which is the 3 pin connector labelled "GPS" on the ECU
If this above fails, and the connector/cable to the JetCat Info Display is intact, please contact the dealer you got the unit from (or ask away here

)
