I checked and discover that the ECU is faulty so my mechanic bought a free code ECU but still the same. ECU does not open injectors but fire coil. ECU not working but want to replace it with free code ECU in Toyota Tundra.
Do you
have the same problem?

Hello,

When you replace the Engine Control Unit(ECU) in your vehicle, you have to have the ignition keys reprogrammed to the ECU at either the dealership or at a locksmith. These are the only two options available. Please get back to us with how things are progressing.

Thanks,
Alex
