Hello! My name is Pavel. INST X_Customs_service
I have one of first hardware release Hellen121Vag.
Trying to start Audi TT APX Engine, it's after full rebuild with forged rods and pistons. Also stocked to 2.0 liter displacement with ALT engine crankshaft.
Hellen board arrived "as is" and now I'll report some steps to start it.
1. Before you plug in USB connector check jumpers for your configuration because it's unversal for VAG family ECU ME7.5 Pinout for MAIN Relay 21 or 23 pin. It's critical for power up from ecu connector
2. Plug in USB with Pressed Prog Button. Write firmware in dfu mode.
3. Start TunerStudio and create project for settings your values of injectors and pinout.
Now we are testing this board and creating base tune.
