A timing light belongs with your automotive essentials, especially if you’re helping a friend get his troubled vehicle moving. When you ask him where his timing light is, the last thing you need to hear while standing in the cold trying to get the damn thing timed out is, “Um, I don’t have one.” You can get a light like this Xenon Automotive Timing Light for not much scatch — it’s a good idea to keep it with your portable set of auto tools.

It’s a bare bones unit, but that’s a plus in this case. Trigger-activated, with a clamp-on inductive pick-up, it features a xenon bulb — other than the xenon, we’re almost sure it’s the same model you could pick up for cheap about 20 years ago at Kmart.

5 Responses to Cheap-Ass Tools: Xenon Timing Light

    Keep in mind that with alot of modern cars without a distributor a timing light is completely useless.

    Just like Jim says … My nephew came over to borrow my old cheap-ass timing light. He wanted to advance his timing on his MR2 a couple of degrees to take it bracket racing. I said, “Um, wouldn’t the control computer just compensate?” He thought a moment then turned a bit sullen when the reality sunk in.

    Haven’t used that timing light in years now, largely because I have newer cars.

    Jim: Even when vehicles have electronic ignition, you still often need to set static timing if you’ve disassembled anything. Many vehicles have a method by which you disable some of the automatic timing adjustments (usually by jumpering a connection on the computer) for that purpose.

    Why? Regardless of how automatic the procedure is, there’s still some method of measuring the physical position of the cam/crank, and that method can (and often must) be adjusted during heavy maintenance.

    Brau: This also offers methods for you to adjust timing for performance by tricking the computer into adjusting the timing where you want it. Often when light racers (read: autocrossers, weekend-fun-at-the-strip guys) want to advance timing in modern engines they’ll either use a resistor (or other low-buck electronic mod) to adjust the timing sensor input — or sometimes just physically rotate a cam angle sensor or such — so that the computer thinks it’s adjusting to zero when it’s really advanced.

    But regardless, a timing light still offers the only way to see what’s going on and is still a necessary tool either for checking the result of these adjustments or troubleshooting timing issues (electronic or no).

    Do you think xenon-headlights are the next step to increase safety?
