Just had a read of your How-to.. nice write up :) How do the ratios of the small-block chev pulleys compare to the stock datsun ones? Also, could you take a pic of the crank pulley?

Yes please!

Mate your a bloody champion :)

Hi guys,

I'm switching over to programmable ignition in the next week or so (Megajolt)
I've been hunting for any references to the stock datsun dizzys curves, found one so far:




If anyone knows of or has any more maps for datsun distributors feel free to add them.
What I would like to do is adapt one of these curves to the programmable ignition map like this:




All the load and rpm scales can be adjusted if needed.
I need a little help adapting this to the Megajolt map.
I thought it would be good if you could have a stock datsun dizzy curve to start as a base-line for further tuning..
Others could even upload links to their custom maps in an excel sheet etc into this thread to keep a repository for any fellow datsun owner changing to programable ignition...


Cheers,
Sam

I didn't even think about it but my automatic vacuum pickup is on the #3 & 4 side. Would it pull enough air to affect the mixture so much.. I think it might. The carb is setup with the primary barrel closest to the engine..
