I have a 99 SS and want to start doing some data logging like I did with my 85. What programs are out there for an OBD II car?

 

AutoTap is probably one of the better ones. They have a version called "EFI Live" that allows you to alter program parameters temporarily.

There are a few others also.

 

i'll have to set in and say that the Autotap scanner just flat out sucks a big one for LS1's. I had it a while back and a typical log down the track would net like 8 records. It was very slow... pretty much unuseable

Hp tuners has a awesome scanner built in with thier tuning software. it has really useful features like custom histograms.

 

Thanks for the input guys. I noticed that Tunercats is coming out with a scanner, so I think I'm going to hold off until it finally makes it out and see how theirs does.
