The whole nissan CAS issue was only raised after multiple users (me included) had issues with the piece-of-crap AEM ecu that is clearly unable to process the signal correctly.
Do you really think Nissan would use a fundamental sensor that did not work (Grp A racers included?). The car was manufactured for what 9 -10years? I must have missed the change to crank AS on R34 or Z-tune, or mines or HKS or or or or......
For info the 360deg markings would give rise to a 24Mhz signal at 8000rpm, a 60-2 gives a 8Mhz at 8000rpm.

The problem is with non_nissan ecu`s.... Apperantly nissan has a fix for this in the stock ecu... and the stock ecu isnt exactly a tuners dream...
