The person talking about being 180 Degrees out of time was probable referring the the physical location of the rotor tip in a distributor . Because if you line up the timing marks on the crank pulley . You could be at top dead center on the compression or exhaust stroke . If the motor was not starting it would be firing on the exhaust stroke . Line the marks back up to what was thought to be top dead center on the compression stroke . Pull the distributor back out rotate 180 degrees put it back in , to get engine to fire . Hence 180 degrees out . But since the cam rotates at half the speed of the crank yes it would be 360 degrees out of time in a 720 degrees 4 stroke rotation. Herd the term being out 180 degrees a lot growing up with carburetor/ distributor engines 1970-1980’s . ✌️✌️Have a great day my tuning Brothers & Sisters see everybody at PRI 2018
for a 2jz engine the best ignition timing base is 10 or 15 degrees (or 0 degrees) with haltech PS200
It doesn't matter what you select as a base timing, provided you can see that timing mark easily with the timing light. It's just used for synchronising the timing that the ECu is displaying on the laptop with the timing the engine is actually receiving.
good thank s Simon
with haltech PS2000 it is possible to make calibration (base 66 degrees)(66 + 360 + .....)
Yes, you can adjust the base ignition timing on a Haltech PS2000 if that's what you're asking?
