I use a Dashawk. About $250 at Amazon and it does other useful tricks as well. Displays readouts from a wide variety of sensors. I monitor ambient air temp, intake air temp, coolant temp, vacuum/boost (I wish boost), instant horsepower and instant fuel economy. 0-60 works just like the EVIC.
Have you seen the new Diablo Trinity? http://www.diablosport.com/index.php?module=htmlpages&func=display&pid=151
I run 1.59-1.65 60' all day and my best 0-60 is a 3.45...mostly 3.6-8's Now my friend ran a 1.46...that's like a 3.2 0-60 1.4 flat.... 3.1 1.5 flat.... 3.3 1.6 flat.... 3.5 1.7 flat.... 3.8 1.8 flat.... 4.0 Just from my personal experience
The Trinity is very cool, and does the all same things as the Dashhawk plus a Predator. But as I had the Predator already, I went this route.
