4-1
i have 4-1 trigger in cam. all sequential 4 cylinders .the ecu took 3 to 5 crank turns in start to count rpm. how can I solve that ?
If you're running cam primary, you will need at least 2 revolutions of the crank to get sync. Make sure your sensor gap is also correct.
As mentioned, it will take a minimum of 2 crank revolutions, but you can also look at things like the Skip Revolutions setting to try and speed up the starting process. What do you have that set to?
Closing as this appears to be a configuration issue.
