Anyone else using MegaSquirt on a LA motor?

I converted to Mega Squirt 3 last year on my Cuda, it is big block but many of the problems and hurdles are the same. I could not be more thrilled with the outcome. But in truth their website is totally bewildering if you are new to it all. I ended up purchasing a cheapy laptop that just stays in the car. Then I can just pull over and tweak on the fly if I want to. They offer some classes every now and then via local,race shop, I have found the classes to be very informative.
