How to Scope outputs - AUX 4

Hello All new to ECU Master Black . Question can you scope AUX outputs ? More specifically the Aux 4 Tach output .? Tach not working on Build . Thanks in advance.

Anyone here have an answer ?

Is your tach negative based or 12v based? You may need a pullup to make it work. Aux outs are all negative based.

Can it be scoped to determine the signal that is generated ? Thank you

Aux4 is an output. So u cant measure anything connected there…so nothing to be scoped.

No, there is no scope feature for outputs.

If you want to confirm the generated signal, you need an external scope.
