hey, anybody know how to check/set timing on the CA18DET?
coil packs confuse me…
coil packs have nothing to do with timing…
cam angle sensor yes…
I got this from 240sxforums.com hope it helps
How to PROPERLY set the timing on the CA
Timing marks -The six marks on the crank pulley read clockwise are -5, 0, 5, 10, 15 and 20 degrees respectively.
Timing - 15*BTDC(DE(T))
-warm car up to NOT
-remove decorative coilpack cover
-remove the plug going to the coilpack on the #1 cylnder
-remove the 4 bolts holding the coilpack in place
-remove the coil pack
-get a spark plug wire
-attach one end to the spark plug
-remove the rubber boot on the coilpack
-using electrical tape, attach the other end of the plug wire to the coilpack
-plug the coilpack back in
-set coilpack someplace that allows the body of the unit to be grounded
-attach the inductive pick up to the plug wire
-attach positive and negative power leads to the battery
-start the car
-point timing light at the crank pully
-it should read at 15BTDC
-if timing is incorrect loosen the 3 bolts that secure the CAS and adjust left/right until the timing is at 15BTDC
-retighten the 3 bolts and recheck the timing
-turn off the car
-reinstall the coilpack, plug the coilpack in, and reinstall the decorative cover if desired
-enjoy your newly timed car!
