How to Fix PCMTuner ‘An Internal Error Occurred’?

Question:

I already activated the pcmtuner flash software but can’t read edc16c39 ecu. Always this error ‘An internal error occurred’… Any help?? Thanks

Solution:

If trying to read an Opel vectra edc16 which is not supported, you’ve probably done damage to your pcmtuner hardware depending on how you connected to the ecu.

Opel edc16c39 is not supported in pcmtuner flash modules.

You can read this ecu with the Fetrotech tool plugin.

Always check pcmtuner supported module list before operation.
