Q about computer advanced timing

Chipdog · 08-07-2001, 06:43 AM

I know you have to have the plug out to set your timing but what should it read with the plug in? If you rev the motor should the timing go up and about how high? I am having some power issues and have had computer problems in the past. Just another idea.

Thanks for the help

Try revving & holding the engine @ 2000rpm & setting the timing at 36 degrees advanced. You can buy a special tape that you put around you dampner that will have numbers that high. Hope this helps a bit.

That's a tough question to answer. If the spout is plugged in, and the system is in closed loop, the timing mark should be at 10 degrees. That's the ECM's job. As you accelerate the engine, timing will advance according to demand, but there isn't much demand when the car is sitting in your garage, with no load. Odds are that you will see it start to advance, but promptly return to 10 degrees, or at least close to that. The ECM bases it's decision to advance the timing on more than just the signal from the TPS. All that signal tells it is that the driver wants to go faster. If it's BAP or MAP tell it that there is no load, why should it advance the timing?

Hope this helps.

Take care

Now thats what I was looking for. I thought my computer was messed up because it was not advancing the timing.

Thanks Chris for setting my mind at ease
