Advance curve in the standard Metro Turbo dizzy
Turbo Mini Forums

Hello,
I recently had my local tuning guy bench test my Metro Turbo dizzy (unmodified), and he provided the following results:
2 deg @ 1200, 4.5deg at 1600, 6deg @ 2000, 8deg @ 2400, 11deg @ 2800, 12deg @ 3000, 14deg @ 3200 and 15deg @ 3800.

I'm assuming that this doesn't include the 7 degrees of static advance recommended in my Haynes manual....

Does this sound close to right?

For info, I'm trying to get started with a NoDiz distributorless ignition system - but these figures seem well short of the kind of advance recommended by various sources.

(I've set base timing at 7 degrees, and so have these exact numbers in the map.

Thanks!

There's plenty of maps on here to get you started.

Have a look here...

In the 13's at last!.. Just

Thanks - it's interesting that the dizzy curves that I can find (plus my own) are so much more conservative than the maps I can find - I guess that's where the power is - as long as it's not detonating?!

As maximum boost wasn't reached until about 6000 rpm (due to the boost modulation fitted), the advance was set for running maximum boost. As there is no boost retard fitted to the dizzy, the advance 'curve' just flatlines at revs where the turbo might be boosting. As you are able to take into account boost and rpm when setting your curve in megajolt, etc, you can have more advance at lower revs than the dizzy would have.

Looks like it would work quite well on the supercharged engines as well.


And a bit OT.

Thanks for the info, metroturbo - that is interesting stuff on the advance "curve" built into the dizzy.
The NoDiz phone app is quite cool, and a bit interesting, but perhaps not super useful for my taste. It does RPM and shows the current advance (I don't yet have any other features enabled, such as load, intake temp and coolant temp). What would be great is if the app allowed for adjustments on the fly.....
I do like NoDiz, but then, I haven't played with Megajolt!

I believe there is already software that is working with the Megajolt, but connecting it is not that straight forward as it doeasn't have bluetooth built in.

RPM is one feuture I'm looking to get from it. But it would be perfect if it could communicate with wideband sensor controller.

Talk to Matt @ NoDiz (Motorsport Electronics). I find him to be quite helpful.
