YOU can synchronize the crank sensor. Doesn't require factory scanner.

May require a scanner with live data info though.

Procedure goes this way, Drive car in 3rd gear...2100 rpm...30 seconds.. with a 50% load.

Keeping the 50% load is the hard part. Knowing you are at 50% load requires a scanner with live data.

Getting a 50% load requires just the right up-hill ride OR using the parking brakes.
Too much brake & they will burn-up.
