Timing Issued From Cas

[tyra skyline]

i have a gtr 33 vspec inported from jp and it was taking into the work shop to service when i notice that the cas was fully retard and the timing in the power fc still saying 20 degrees why is this so . can some one explain ,

PFC controls timing so I think it is set at least number as a reference point.

I think you will find that the PFC has been told that that setting is 20. So even if you change the CAS, the PFC should still say 20.

You need to make the PFC agree with the actual timing (via a timing light).

IF THE CAS IS A THAT SETTING WOULD THE CAR REV SLOWER OR FASTER IS THERE ANY GAIN TO THE PERFORMANCE WITH THAT SETTING
