I was hanging out with my friends last night and this guy just bought a SC 01 Z28.... really awsome car! Anywho he had this computer looking thing that he had pluged into the PCM. It read and logged coolent temp, a/f ratio, knock, O2 sensors, rpm and speed.... it even graphed and recorded runs. What exactly is this thing? Is this a fancy scan tool or something like it? They hooked it up to my buddy's GTP and took it out for a run.


Thanks for your help!

that's not a scanmaster from what i know. sounds like a unit somewhat similar to the new Gtech or something. but idunno if the new gtech sees O2s, A/F, etc...

 

If it looked like this it was.
