Flashing(Programming) ECMs
Disclaimer:
1320 Electronics is not liable for damaged ECMs.
Due to the limited buffer size in the ‘ALDL Bluetooth Adapter’, only software specifically designed to
flash ECMs with this ‘ALDL Bluetooth Adapter’ should be used. This adapter contains a very small
buffer that can overflow easily, resulting in data corruption and possible ECM failure. Flashing ECMs
even with software compatible with this ‘ALDL Bluetooth Adapter’ can result in ECM failure. Flash at
your own risk!
Programs that use this ‘ALDL Bluetooth Adapter’ to flash ECMs should throttle data sent to the
adapter. The easiest way to accomplish this is by sending the data byte by byte, and waiting for
each byte to ‘reflect’ back through the adapter. By design, anything written to the adapter will be
reflected back to the sender. By waiting for each byte to reflect back, the flashing software can
minimize the chance of data corruption.
Other things to do when flashing an ECM:
1.
Ensure the vehicle’s battery is sufficiently charged.
2.
Ensure that the ‘ALDL Bluetooth Adapter’ is securely connected to the ALDL connector and
power.
3.
Ensure that computer/phone/tablet is sufficiently charged or connected to a power source.
4.
Ensure that no other applications are running on the computer/phone/tablet.
5.
If using a phone to flash the ECM, ensure that messaging and phone services are disabled. This
can be accomplished by removing the SIM card.
