Anyone know how to check engine timing?

Has anyone ever checked their timing on the supra?

Which timing?

Timing light?

That's an interesting question, actually. I know the procedure to do this, but the equipment will be different these days to what I used to use.

 

I used to use a decent timing light to check ignition timing, with an inductive clamp around the HT lead to No1 spark plug. But since the advent of plug-top coils, I haven't had the need to check this.

 

The ECU should keep a good enough check on the ignition timing to negate the need for a timing light, but if I wanted to check the timing just to satisfy my own curiosity, I don't know what the latest type of HT pick-up even looks like these days!

 

(Ashamed to say that as it was always such a basic piece of equipment to have in my toolkit)

 

I think I'd probably be able to hack my old timing light around to make a pick-up to fit the new plug-top coils.

Some of the inductive timing lights will pick up the low tension feed to the coil, used to use this method on my old S14.

This is what I did. Just opened up the plug on the ignitor and connected it to one of the wires there (can't remember which one now!)
