Reprogram Denso ECU / VIN

[tixen93]

Is it possible to change the VIN of an engine control unit?

Type: Denso 89666-60F10

Software Version: 36A16000
Vehicle: Toyota Land Cruiser GRJ76

 

I want to experiment a bit and got the same ECU from the scrapyard.
Unfortunately the car doesn't run with it.
The type and software version are identical.
