How-to Tuning Collaboration

[TheKodiak]

I did buy the "Y" kit. So it comes with both. I'm guessing I'm supposed to use the obd1 and not the obd2 cable? Glad i got both lol. Besides, it's better to have it and not need it, than need it and not have it! An expensive frame of mind, but it works with the wife!

TunerCAT OBD1 & TunerPro RT will both run just fine on Windows 7 or anything newer.
(JET DST runs best on Windows XP - not that that matters anymore ...)Can anyone else answer that?
By the time I got any good at tuning LT1s with TunerCAT, I'd stopped looking at printed calibrations.
It was a few years after THAT that I'd just begun using TunerPro RT, so I never used TunerPro RT to print anything out.
I just look at whatever I need to look at on the laptop.
Since TunerPro RT's LT1 definition files can see parameters that TunerCAT's LT1 definition files cannot, use TunerPro RT to print out the calibration, not TunerCAT.If TunerCAT will be in Sat, then you'd like to flash the pcm with $FlashHack, yeah? You got an OBD1 cable?

you have an obd2 connector but with an obd1 swap will be running the obd1 data through an obd2 style port. this is actually something gm did from the factory for 1995 model LT1 based cars and most people call it obd1.5.

confused? you should be. maybe this will help.

Not really. Once I saw the cables, it made perfectly good sense, and then having to just swap the pcm and knock sensors with no re-wiring. Afterward it became obvious that I'm actually going into what you called, obd1.5 lol. But of course the guidance I'm receiving has helped a lot! By the way, do I need anything extra for DataCat? Seems like I just need the software. Thanks

Just the software and everything else you already have (or will have by tomorrow).

Sorry big guy, I failed to mention I got it today. That's why I got the awakening. Monday I'll start the programming. In fact, the knock sensors will be in on Monday too. Oh, it turns out I didn't brick the obd2 pcm. I accidentally left the lights on and it killed the battery. So when I swapped to my back-up battery, no fans, no christmas tree, or anything, like the the day prior. So I went ahead and "read" the pcm (with my xp desktop) and got the desired results, not the PO's tune, but the stock tune from the file I got (Thanks Doc) and restored. So I went over it, and made a calibration for the tires, and . Everything went well. But right now I'm getting everything squared away for the new brain.

UPDATE: I haven't fully made the swap yet. Sadly, my luck has seemed to dribble over to TunerCat. Although I did manage to read and flash. I can't seem to keep it connected. Once FlashHack is open, I go to EE and plug the obd cable in and turn the car on (not start). I give it a few seconds and load the kernel, then I get stuck in a loop (sometimes the fans and stuff come on briefly, then go off). I've gone to unload kernel and disconnect, still it won't budge. Yesterday, while I was having my repeat moment, I manage to change the VIN. But then the loop again, so out of irritation I said Beef It! And flashed the bin shared by Dissod, and by some freaky miracle. It went through the whole process. Not sure if it works, but I would like to think my pcm isn't bricked. However, seeing how I'm now having issues with TunerCat, and the obs1 pcm. I haven't fully committed to the swap yet. I went ahead an attached a log of my session, In case someone can shed some light to this. Thanks
