Ignition timing
- Thread starter stan
- Start date
To set/check your ignition timing. (Courtesy of Turblio)
Run engine to normal temperature,
Stop engine,
Disconnect TPS,
Restart engine and rev it to 3500 rpm 3 or 4 times (this puts the ecu into timing reset mode I have been told)
connect timing light
you want the 20 degree mark (right hand side mark)
move dizzy so the correct mark lines up with the pointer
stop engine
reconnect TPS
restart engine and road test should be better than before
listen for pinking, if you are not using a high octane fuel you may need to back the timing off to about 18 degrees
CO timing?? CO levels maybe? That depends on the age of the car. Less than 3.5% CO for J reg or earlier, alot less (don't know the figure off hand) for K reg or newer.
