just wondering whats the best diagnostic software to use when connecting my laptop to my cars computer. I just want a prgoram that also has the capabitlityof checking my sensors and being more specific what is failing when my car messes up right now......cause i think my opti might have went again or my crank sensor went.

 

I think the only one available for the LT1 that will give you the full functionality that you're looking for is going to be "LT1 Edit"

 

That's all I could think of too slvr.
