Vmax 09 ECU HACKING

There are two possibilities

It uses a 7052 cpu in which case you will have to cut it open to find the BDM port to download the binary

OR

It uses an M32R cpu in which case you can download the bin from the wire harness. As the m32r option does not require cutting open the ECU I would try that first.

Step 1 of the m32r is figure out which pins on the ecu are for flashing. You are looking for a TXD, RXD and FWE. You will also need to find a power and ground to power up the ecu while you flash it.

Step 1a get a manual and identify all the unused pins on the ecu connector.

Thank you for your fast reply unfortunately it uses 7052 cpu and the bad thing is that I must clone also the Immobilizer :(
Any ideas?

What he said....

Flashing the ecu does not change the immo info. As long as you put the ECU back into the same bike you took it out of there should be no problem.

Do you have a spare ECU to cut open?

a spare ecu I don't have....but I would like to buy one in order to make some tests.Where can I find?
Thank you

this is correct apart from yamaha system which ecu and key reader (airiel) are linked together so if you use a different ecu it will not work .
there are 2 ways around this:

reset eeprom in ecu and set to virgin ( a reset file would needed to be made )

or alternatively

buy bypass ,easy and cheap (ebay) . Think this would be the best option
