ECUType / PECTELECU

PECTEL (Stack) ECU

The Pectel data format is also used by MoTeC dashboards and some ECUs. For compatibility with the Race Technology interface the Pectel ECU should be configured to output the “STACK” data set.

The ECU must be set up to output data at 19200 baud with standard checksum. Start byte must be set to 0xA3.
