Those guys with the dynos can figger out just what the engine likes better than my ear, and the closest drag strip is 60 miles away, makinf that method inconvenient at best. Tuning articles all over the web and in mags will tell you how much what rpm for all sorts of engines and builds from dyno tests. and BTW, always use the positive stop method to first find TRUE TDC. The old self powered orange Xenon light my dad gave me over 40 years ago seems to be pretty consistent so far.nce I run MSD unit (concealed under dash) I use a non dial back light, since the digitals won't work on MSD, and a timing tape to plot curve. The best I have is comparing 2 lights, after a wary informational static timing check when possible, since worn components can allow several degrees change when running. Setting ignition timing of aftermarket CDIgnition on dirt bike that required repositioning the magneto rotor and running key-less.Īs far as accuracy, it's always a nagging worry. Testing for spark in intermittent electronic ignition module failure situations. Testing coil wires, dist cap and rotor in No spark at plug situations. Vacuum advance canister installed where a pressure retard canister was called for ( Turbocharged Corvair).Īdjusting a few centrifugal advance curves. Pooched vac advance canisters ( with mityVac pump). (Dwell meter would have pointed this out too,) Spark scatter due to badly worn distributor shaft with points ignition. They all serve the same purpose but offer different RPM ranges, ability to operate a multi-spark system and offer features such as timing manual advance, a dwell meter, and the possible option to work on four-cylinder, six-cylinder, or eight-cylinder engines.I apologize for bump the old topic, but I have some interesting observations that I would like to share, maybe this will help someone in the future because once I was on the lookout for useful advice.Here are some Engine issues that my timing light told me about. What brand manufacturers offer automotive timing lights?Īutomotive timing lights come in three styles: inductive, digital, and self-powered. Not every timing light is compatible with MSD systems, so be sure to check that the one you want can meet these requirements before purchasing. To properly measure this sequence, the timing light must be able to show the beginning of the sequence. Typically, the distributor only provides a single spark for an ignition sequence, but in MSD systems, there are a series of them disbursed at a specific timing. How do timing lights help multiple spark distribution systems (MSD)? Units with a dwell meter measure for how long the coil is being charged and allow for prevention of pitting or burning due to an accurately set point gap. Adjustment knobs coupled with a tachometer allow for more precise timing measurement at different RPMs.Adjustment knobs that allow for the timing to be read at different RPMs are available on some models.It should be able to read both two-cycle and four-cycle engines. The standard timing lights come with a xenon light tube that is able to read timing when the vehicle engine is at idle.Knowing this allows adjustments to be made via manipulation of the distributor cap to make the spark plugs fire before or after the piston has reached the top dead center, depending on the malfunction or issue that needs to be fixed. By aiming this strobe light in the proper place, usually the crankshaft pulley, you will be able to read the degree markings on it, which are indicative of where the crankshaft is in its rotation and the respective pistons. Inductive timing lights, when connected properly to the car's engine and battery, detect the electricity every time the plug fires, and every time the plug fires, the timing light shoots a beam of light. The light is powered by the vehicle it is being used to test. The light can be a stroboscope that may use a simple neon lamp or a xenon strobe lamp that provides brighter light and better use in daylight or in shop lighting. Provides the ultrabrite flash needed to see engine timing marks under daylight or bright conditions. Includes inductive pick-up for simple connection. The Xenon timing light allows the dynamic ignition timing to be set. Timing lights are diagnostic tools used to observe ignition timing in vehicles with distributors and are available as self-contained units or as a part of a more comprehensive engine analytical tool. Suitable for any petrol engine vehicle with 12v ignition systems. See Your Car's Diagnostics More Clearly With Automotive Timing Lights
