For those of you who've swapped LT1's in, what do ya'll use for Data logging, and tuning? I've got Datamaster EE and OD on my Laptop, but I don't know how to use it. I've got a cable to hook to the DLC, and when I open the program it says PCM Detected. It says I have to open a certain file, and I don't know what file to to open.
I've also got CATS and AutoTap, but I heard Datamaster's the best so that's what I decided to use.

 

with Datamaster, when you open it up, go to File -> Record ALDL Data and a new screen will pop up. Then go to File -> Open, make up a filename, and hit ok. Hit Start and record for as long as you like, then hit Stop, File -> Save and you're done. Close the Record screen and you can view the file. I love Datamaster

 

LT1 edit.

 

Well, I already have Datamaster, so I'm gonna try and get that to work. Is there another program that you use to tune the car?

 

for my initial bolt-on tuning I used Ion at madz28.com he is pretty good..

After custom heads and cam I had to go to the dyno and get it tuned on the rollers by carolinaautomasters.com

if you are looking to do it by hand, have fun, I never tried it though I do have LT1 edit, I have not used it much, just to troubleshoot occasionally and load the first tune the car had..

 

It's not that bad. I've tuned mine a little bit. I had it on the dyno a while back but my cable quit working for some reason, otherwise I could have done more extensive tuning.
