Ahh, I understand now, thanks very much!

Thanks for your reply. How do tou tell the difference?

Gidday all. I have a V1/2 WRX plugin ecu. Have been doing some work on my engine and all round setup, im trying to get the engine back up and running but am getting a constant trigger 1 error every revolution and am puzzled as to why. Have performed a trigger scope while cranking but im unsure how to read an oscilloscope. Cheers!
