Calterm CM2450

[APC]

the BHQs are not able to be read FULLY via calterm, or any other tool as far as im aware.

the ECM does not give up the 6th block of data, which stores some sensitive data about RSA encryption and a digital signature verification process (don't quote me on this...)

only way to read those ECM's out are with a JTAG, reading the processor directly or by finding a way to extract the 5 blocks, and attempt to rebuild the 6th block of data that it does not give you.

none of the methods mentioned above can be done with calterm, there is a 3rd party software that does give you a partial readout (wont mention the name due to forum rules but it is used frequently by diesel tuners, HP-xxxxxx) but it is useless unless converted into intel-hex format and rebuilt properly...

as far as the X15 2450, you should be able to read out the data just fine if the engine is a BKR engine code, if it is a BNN, it could possibly be the same story as the BHQs?...
