CAS trigger wheel backwards?
 

I know it's designed to only go on one way, but would it be possible for someone to install it backwards if they tried hard enough?

Assuming the JDM Ver. 4 CAS is designed the same as the USDM CAS, mine is acting like its backwards, based on slow-motion videos I've taken of it. The rear rotor has compression pulse opposite of the trigger wheel G sensor tab, and T1 fires when the tab passes by, even though it should be T2 firing. According to the data I've been provided with on USDM cars.


The car still starts as long as the plugs are fresh, but it runs like crap and won't rev pas 4000 and I've checked everything but the fuel filter (which I'm gonna replace this weekend).

Yep.... it only goes on one way.

Car should run okay on just leading plugs.

It doesn't. It does seem to run better with just them, though... Assuming I'm right and everything is backwards, the injector timing is way off.

If it runs better with just leading, swap the trailing coil plug wires and try it.

White plug going to cas is on the top?

Yeah... it shouldn't run at all if those were switched.

I just took another video and I seem to be getting T1 spark at the same time that Rotor 1 compresses. So maybe this was just all in my head.
