Years ago I was working with a Greddy Emange of a 4G63 turbo setup. This unit works fine as far as conditioning the airflow readings but smokes the injector drivers out of the ECU if trying to work with outputs.
Since that happened I do not install anything between the ECU and the injectors to condition the tune.
I am curious if this maybe what happened in your setup.
