BenKey Posted February 18, 2004 Report Share Posted February 18, 2004 I've seen that same page before. I think there was some discussion about it's use on LS1tech. Hadn't read it though. Link to comment Share on other sites More sharing options...
m396 #00-011 Posted February 19, 2004 Report Share Posted February 19, 2004 this is pretty new to me, anyone know much about this? tuner They look to be a new compition to LS1 Edit, although currently, they're not shipping. Sounds like it will be soon though. I look foward to whatever EFI Live puts together, and hopefully soon! Link to comment Share on other sites More sharing options...
Fun Guy Posted February 29, 2004 Report Share Posted February 29, 2004 Also, all of the diagnostics will still work even after being programmed as we are all just modifying GM's original code and not replacing it. Thus if you take it into the dealer they can still diagnose the truck as normal and honestly have no way of knowing the code has even been modified All the GM techs can do is load in factory stock GM programs.Later, Bryan Is it possible that something they do could overwrite changes I've made? I've gone in and had software updates to my PCM (for example, to correct a slipping/sloppy 1-2 shift via a GM Tech Update) and I'm wondering if they could supplant my modified code with their update, causing me problems....

YES. If they "update" your PCM for anything related to the engine or trans, then they are writing over the tables that are currently in the PCM. If you had someone do a custom tune for you, you can ask if they are aware of any GM updates for PCM programming. Maybe they already fixed that problem when they did your tune... ;) If you are doing your own tuning, it should be easy enough to figure out if they changed something in there...

If they have reflashed your PCM with Factory Updates anything else you've done in terms of programing is History When the dealer flashes your pcm it doesn't leave everything else alone either, its the whole deal. Plus if you get a factory reflash your Edit file may not sequence the Hex because of the differences between the original program and the update.

PCMFORLESS Posted March 3, 2004 Report Share Posted March 3, 2004 Not really a problem though. I can read the new program they put in and then copy the modified tables into the new program and thus be back where we were. When I do exchange PCM's I load the newest GM cal into the PCM and then write the code based on the new segments in the GM cal.

Just the normal GM pain-in-the-butt stuff. It works, just takes more time to go around it with the copy and paste, than just reloading the old program.

Maby when you do this, you need to put out the $'s and keep the old PCM and put it back in when it goes for service? Thoughts? Link to comment Share on other sites More sharing options...

Actually, this is what I did. I had a junkyard PCM flashed to current factory specs, the tuned it with the Mallett specs to start tuning from. This is when I found out about the Segment ID updating. Check around, I got a PCM for $75, then $40 flash fee. Link to comment Share on other sites More sharing options...

And as far as I know all 03/04 computers have the same part #. So no it doesn't have to be a 6.0 computer, the engine parameters are part of the programming not the hardware.
