The importance of setting the correct ignition timing

Setting the correct ignition timing is pretty important to yield better performance and emission, and lengthen the life of car engine. Thus, if ignition timing is improper, you should adjust it in time manually or with obd2 tools.

In detail, setting the correct ignition timing is crucial in the performance of an engine. Sparks occurring too soon or too late in the engine cycle are often responsible for excessive vibrations and even engine damage. The ignition timing affects many variables including engine longevity, fuel economy, and engine power. Thus, I have suggestions on adjustment on ignition timing manually and in the way by auto diagnostic tool.

 

Generally speaking, VDM UCANDAS wifi does well in ignition timing adjustment. With the help of it, you can easily adjust ignition timing. As to manual method, you should warm up the engine to normal operating temperature. Then remove the vacuum advance hose from the distributor and plug the hose. If the engine runs fine with no surging or pinging, you can advance the timing. With the engine off, advance the distributor a couple of degrees. Start the engine. If it starts fine, shut it off and advance the timing a couple more degrees and restart the engine.

 

Now take the car for a test drive. Drive at several different speeds, and accelerate hard once or twice. If any pinging is heard, retard the timing a little more. Also, try driving steady at about 40-50 mph at part throttle. If any slight surging in the engine is noted, retard the timing a little. Now your car has the optimal ignition timing.
