SafetyMode (2010-11-15 21:36:52)

Safety Mode - prevent engine flooding caused by not following firmware upgrade steps


Usage - for firmware 1.1.83 (or newer)

From firmware version 1.1.83 the Injector and ignition outputs are disabled after firmware upload.

  • but stepper outputs aren't disable. Lots of cars have ignition coils connected to stepper outputs. IMHO stepper outputs should be disable also. And p259. And specfet.

To reenable the ECU:

That's all. Nothing special needs to be done in the normal case. For advanced users:


Background information: - for the curious

After firmware upload the config is usually absolutely wrong.

Solution:

From firmware version 1.1.83 the Injector and ignition outputs are disabled by default, until they are enabled by

either


Advanced users - will not be needed since VemsTune 2010-11-xx and newer calculates this and sets after config upload.

Calculation example for prohibit variables:

There is a special code to prohibit variables which works with any firmware for developing, Use it only if nothing else works: 0xBEEF
