MSD digital E-Curve? who's got one?

I had one. Very expensive. I got it because I was about to have my engine dyno'd and I wanted to make it easy to change the curves while on the dyno. It works good, as far as it goes, but you have to use the pre-set curves on it. I found the centrifugal curves to be good, and have enough variety, but the vacuum curve choices available are clearly designed for modified engines with big cams. If thats what you have (lower than stock vacuum) then it should be fine. Mine was not modified and eventually I got rid of it, because I didnt need it, and the settings were too low who I had stock vacuum (15 + inches). There is some good info on it on MSD's website, and there is also a program you can buy on ebay, I think, that will graph the curves out for you.
