Reason:

PCMTuner ECU Programmer with current version cannot bypass PSA protection, and there will be a patch to fix this problem on the next version update.

 

Solution:

Manually edit Tprot off, for C10 no need while for C60 have to manually edit.

 

Add simple 0000 mask to file at address start 2CDB78

Try 2CDB78 => 0000 => 2CDB7C Patch for write protection

Feedback
