Nissan CAS
Posted: Sat Jun 06, 2009 3:00 pm
I know Devojet has been messing with these things lately, so i'm hoping he has a little input for me.
The CAS I am using is off a CA18. It has dual optical pickups in the one sensor with 360 x 1 degree slots around the outside and 4 x inner slots of different lengths. Some people are doing some pretty cool stuff with the MS2/extra code these days and as far as I can tell that sensor can be used with MS2/extra without any mods.
BUT I have a v2.2 MS1 running extra code, so that's not really going to work for me. After doing a bit of googling I found that AEM and Autronic actually retro fit a different trigger wheel to the Nissan CAS, which looks like this one...
which has 24 slots on the outer and a single trigger on the inside. Doing a little skimming throught the MS1/extra manuals I seem to think it's going to work. I'm going to TRY to sit down today and have a good read of the manual and get my head around it though.
OH, and there is one more thing to consider. This CAS is driven on the front of the cam shaft on the Nissan engine, on MY engine it will be driven off the opposite end of the camshaft (back of the head) and so will spin the trigger wheel backwards compared to how it would normally. Now I think with the existing trigger wheel this would cause a problem, but with the 24+1 wheel it's not going to make a difference.
