No need for attenuator. This probe outputs suitable voltage so there is no need for attenuation.

I assumed each injector would be monitered better individually?
Advantage is that we can see all four injectors. Of course it would be better to measure individually and if you have four clamps then you can pick each injector separately. But then there is no free channel for crank. If you have two clamps then use one clamp for two injectors and other for remaining two. Then add cam and crank also.

Thanks for the attenuator info, The Ecu will be here today, so I will set it all up later today, 2 injectors in 2 clamps 1 & 2 + 3 & 4, is this the best way or would you rather have 1 &4 + 3 &2? Then Cam & Crank, I plan to do long time base with Cranking from Start, I will then save a couple of others, I am having to take this on & off my lift, so I can do other jobs in my garage, But will get it back on lift once ecu Arrives today, Thanks Terry

It doesn't matter which cylinders are in one clamp. Whatever combination is easier to do.
