There are 2 adjust buttons to bring the degrees up or down.Īt 900-1000 idle, I have 14 on my indicator.Īt 15-1600 I can line up my zero with about 24 to 26 on the digital In my case at an idle, I have my display reading 14 and the 0 mark on the damper is bang on my timing pointer. ![]() So as far as I know, you hit the adj button/s to bring the mark to zeroon the damper. Today I am at the "let's finally see where the heck this thing is" stage since my FE break-in 2 nights ago. I have set up my MSD using the default blue advance stop bushing ( gives 21 degrees advance) Chose a light blue and a light silver spring as i wanted it all in by 3000 rpm I really need to know how to time my car by using it in a nutshellĬar is static timed now for 14 degrees. It’s a new digital world out there.I have had the luck of having a friend drop off his snap-on digital advance timing light. What’s interesting is that the modern distributorless ignition systems (DIS) employed on all late model engines don’t require a timing light and don’t even offer a TDC mark on the balancer. The light that we referenced (PN INO-5568) is pretty sophisticated, but Innovadoes offer others that are less expensive. With the engine revved to full advance, the technique is the same - adjust the crank TDC mark until it lines up with the zero (TDC) mark on the indicator tab and the number on the back of the light will indicate the amount of total timing.įor example, the Innova digital timing lights that Summit Racing sells offer a display that will show system voltage (it uses power from the battery to run the light, so volts is accessed), dwell (if your engine is equipped with points), rpm, and the amount of timing the light has been delayed. You use these lights exactly the same way as the traditional dial-back lights, but the display and the options can be somewhat confusing. Instead of a traditional knob, these digital lights generally use up or down arrows to adjust the timing mark. Instead of a dial, these lights generally use a digital display screen with not just the amount of timing dialed back but also all kinds of other information. The modern version is a digital dial-back light. The dial on the light then indicated the total amount of advance. In this case, you rev the engine to maximum advance and use the dial to line up the TDC mark with 0 (zero) timing on the tab. The original dial-back lights employed a simple dial on the back of the light. There are several tapes on one sheet based on the diameter of the balancer.īut if you work on multiple cars/engines, it is time-consuming and cumbersome to attach a timing tape to each engine. These are adhesive tapes that adhere to the balancer and offer accurate timing numbers so that you can use a standard timing light to check maximum advance. ![]() The simplest way to compensate is to use an MSD timing tape. But if you need to set your initial timing at a figure greater than what is offered on the timing tab, you have to guess, which is never good. A typical timing tab offers numbers up to 14 to 16 degrees Before Top Dead Center (BTDC). This works great as long as you are only setting initial timing and only if you can line up the marks from the timing tab on the engine to the TDC mark on the balancer. A normal timing lightflashes the instant the Number One spark plug fires. Jeff Smith: What you are using is what is commonly referred to as a dial-back timing light. There’s probably an easy answer but it escapes me! Thanks When I push the button, the timing moves but I’m not sure I know exactly what’s really going on here. I just bought a new, digital timing light to replace my old original light.
