I am trying to get my rb25 up and running on aem. I installed the supplied aem CAS wheel and performed the setup the options in the software for it to work correctly. The car starts up and drives fine, but I'm unsure if my timing is synced right. I have an advance digital timing light and with it set on the 2/4 cycle setting for an inline 6 it gives me the wrong rpm readout on the light which makes me think something is off with the light.
I don't trust what its telling me the timing is at. It reads about double the actual rpm the engine is running at. If I set the light on its other setting 4/4, which i would normally use for an inline 4 cylinder it reads double that value. I.e. with it set on 2/4 it reads around 2000 rpms. With it on 4/4 it reads around 4000rpms. The aem reads around 1000rpms. Any idea what is going on here? I have the inductive clamp hooked up around the lead on the number one spark plug. Any ideas?
Also the timing light reads fine on my friends 2jz supra.
And anyone know why my knock sensor signal is reading 0V... is there some rewiring i need to do to get the knock sensors to work right with the AEM? (No problem with knock sensors on stock ecu)
Thanks for any help you guys can give me.
