Most of the time ECU flashing works without a problem but there is always the small chance that something could go wrong. ECUs from different manufacturers all have their unique characteristics as well as potential problems too.
This article is about issues encountered when writing to a Denso ECU with the
Woolich Racing Tuned software. This could occur if there was previously a problem with communication during a write operation (e.g. USB cable damaged), if Windows shut down during the write operation (e.g. restart after system update) or any number of other possible reasons.
In some cases the bin file on the Denso ECU is not recognized by the
Woolich Racing Tuned software even though it has been written to successfully earlier. In this case you will see a message like "This file does not exist in Woolich Racing Tuned".
If you find yourself in this situation please
do not panic as the Woolich Racing technical support team have seen these problems before. Please
open a support ticket so that we can provide you with further information to get you up and running again.
