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

Here is the factory A12 map:

cylinders=4
mapBins=80,73,66,60,53,46,39,33,26,19
rpmBins=6,10,14,18,22,27,31,35,39,43
advance0=18,21,24,27,30,33,36,39,42,45
advance1=17,20,23,26,29,32,35,38,41,44
advance2=15,18,21,24,27,30,33,36,39,42
advance3=14,17,20,23,26,29,32,35,38,41
advance4=12,15,18,21,24,27,30,33,36,39
advance5=11,14,17,20,23,26,29,32,35,38
advance6=9,12,15,18,21,24,27,30,33,36
advance7=8,11,14,17,20,23,26,29,32,35
advance8=6,9,12,15,18,21,24,27,30,33
advance9=5,8,11,14,17,20,23,26,29,32

I will send you the Excel spreadsheet. You can put new numbers in it and it will generate numbers like the above.

Mate your a bloody champion :)

You can also open the Megajolt file in notepad and just paste that in. It is the .mjlj file.
