Is that correct?

Here's the big question, have you actually tuned the EFI system for your inline stovebolt or are you still running the factory GM V6 program that is designed to run in an async mode(technical term used for the injector firing mode on some GM EFI tunes) at idle.

Have you actually logged data and verified the fuel table is correct for your engine?
Have you changed the timing table so it is correct for your old stovebolt or are you running the factory late model V6 timing table? (You have probably seen them posted in the injection forum on the binderplanet)

If you haven't done all the above but you describe it as starts great and runs great, then I would say the old factory system is doing a pretty good job of adapting itself to your engine.

Have you checked for error codes with your SES-service engine light? Just jumper pin A and B of the ALDL connector and turn the key on.
Count the blinks.

Bill, the quick answer to all of your questions is no. I haven't logged data, changed the programming, read live data, or any of that. I think I will get that USB cable from you on your website, though, that seems the best route for me to go in order to record some live data.
