Using a Scope for Diagnostics

It is good to hear about your son's work.

I hope to post about using logic analysers for ECU diagnostics. I use engine sensor simulators, developed with arduino nano controllers. The simulators are controlled via interface over USB or Bluetooth. This enables ECU testing on the bench, without engine. If you son desires at some point to get deeply involved in tuning, it often involves work with micro controllers, hardware development, and software. The work is very interesting. I am here to help.
