Reply to "Fuel Injection and Electronic Ignition for VW engines - Speeduino Style"

@Sacto Mitch, I just posted a short video the day I started it up. I'll get some video of it actually running so you can hear what it sounds like. Short answer, it feels a lot more powerful and responsive and sounds good, too. It's very subjective data, but I have to say that it has put a lot of grins on my face since I've got it tuned. 

From the non-subjective point of view, you 3 main tables that control the spark, fuel injected, and the air:fuel ratio targets. Each table has 256 cells (16x16) that get filled with what you want to happen at various RPMs and engine loads. That is an amazing amount of precision compared to our old carbs and distributors, even if you have a ton of springs and carb jets.

Here are my current tables shown in TunerStudio:

I suspect most of the power and responsiveness feeling comes from having better control of timing and mixture levels. Anyway, that's a non-dyno observation so take it for what it's worth. 

I'll see if I can get Marianne to do a video while I go by and will try to get a slow run, too.
