if you had to buy a new one, the 2 has its advantages... I've got mine in my Z and like hte knock sensitivity sensor reading... VERY useful. It picks up a lot of stuff I won't hear at times... It also has finer adjustment, two seperate curves (light throttle and full throttle) and can monitor an O2 sensor as well if you wire it that way (the blue wire trick).
