I just picked up one of these last night and i must say I am very impressed by Impakt's handywork.
Great little unit, very easy to use. I have it monitoring revs, speed, airflow sensors, throttle position sensor and temps on my GTR. Peak hold function is very cool also.
This weekend im going to try plugging in my laptop and see how that goes!!
Thus far, definately happy with the purchase. Thanks Impakt.
