First, get it flashed with 3.3.3; the screen shots you posted are for B&G code.

Once it is reflashed, can you elaborate on how exactly it is not responding properly? I do not understand what you mean by "no Controll on tunerstudio."

Are you saying that it will not trigger the injector lights on the Stim in output test mode, even though it is communicating? Or is there a different problem?

The function of D14, D15, and D16 will depend on your tune file.

If you click Enable Test mode and then Fuel Pump On, does the fuel pump LED light on the Stim?

And removing the CPU and grounding the pins on the socket WILL turn on the injector lights - is that correct?

This sounds like it may be a CPU issue. You can contact your kit seller directly by email to see if the daughter card is still under warranty.

We've traced it to a daughter card fault and replaced the card under warranty. New one shipping out today.
