Base maps - A good place to start.
This is the place to go when someone wants a spark, air/fuel, VE (Volumetric Efficiency), fuel delivery, etc. map for their setup that they will be able to use "out of the box". These will be good maps to use, being mostly tuned for specific applications. Grey-ed out areas are un-tuned portions of the map.

As always, if you have something you'd like to add, or corrections for me, please post and I'll update accordingly.

MegaTune (used with VEMS and MegaSquirt ECUs)

I've done a bit of work on the VE table as of late, so an updated version will be going up soon.

I'd love maps for other programs from other people if they'd like to share. I have AEM EMS maps that might go up sometime in the future after they get a bit more work. They are for NISMO 740cc injectors...

One nice thing about MegaTune is that the configurations aren't injector specific. =]

Which map? Spark or fuel? My buddy has a great spark map for his SR20DET, but the fuel map probably won't be any good because he runs giant injectors. What ECU are you going to put this on? The one we have is on an AEM unit.

Do you have a file with a base map for Megasquirt? It's a 2.2 PCB.

I quit.

The maps have been updated as of June 25th, 2008.

The VE map has been updated as of July 13th, 2008.
I've fixed the 50 kPa line and smoothed out the high rpm / mid load area.
