As far as I know there for the most part completely interchangeable, but I did run across one conversation that some don't have all of the internal hardware for the 4L80E. It never became clear which ones though, sounded like it took a EE with a microscope to find out.Quote:

Thanks
I'd like to join in on this too i have two trucks with 8625 running $e6 that have E-fans, and don't want to try to copy all my settings over to $0D in fear of jacking something up.
How many things did you change? :yikes: Wouldn't be that hard, just back up the bin. Take some time in TunerPro. Open 2 instances of TP, old bin new bin and cut and paste from old bin to new bin... you could do every option in an hour.
My theory, by looking at years is $OD was the last one made, 93V8S10 confirmed it with:
they probably found one PCM that GM tried to save a buck on for manual trans? Or just a 4L60E? On an early PCM and code mask? In the end they made one PCM to cover all trans and masks saved money. If it weren't for OBDII they may have gotten better and better?Quote:

Back to my theory of looking at masks $OD seemed to be the last one in this string of PCMs so it's a progresion to better and better, all options built in last one. Since we have found 16197427 which is also by looking at years last one, came mostly with $OD, but has been found with other bins and masks in it and has been changed to other masks. So last one GM made would be the best.
I'm only using $OE on $OD 16197427 PCM becuase a manual bin to strat with has only been found in $OE, I would much rather start with a $OD manual bin. To many changes in bins from manual to auto to start otherwise... wish I could find a manual $OD bin, always been my first choice.
It's not that I made a bunch of changes. I always assumed you had to copy everything whether you changed it or not. i'll give it a shot if it dosent work I can always load a $e6 back to it. I also scowerd the internet when I first started this for reasons the $0D was better than the $E6 but couldn't find any good explinations on what is so better about it.Quote:

Then when I make a change in xdf I right click XDF and change parameter name, I add a "+") so I can look back and know what was changed, I add a "-" when it was removed. Those files stay in that folder for car and I always know what was changed and have starting bin, modified bin and data logs.
I don't know that it is actually better, just the last update to a series. Most documented tuning code is done on $OD, but others are so similar it can be used with them with slight address changes needed. $OD is most popular? Thinking of the trucks it came in most produced is probably why most popular and why most code hacs and tricks are designed in it.
Also, $0D has working PWM converter lock-up. $E6 has the code, but don't know if its functional. Not a big deal unless you install a newer trans.
If I switch to $0D will the PWM converter lockup be a problem since I have the older transmission with the non PWM solenoid, or is there a setting I can change for it?
never mind I see how to disable it. I'm looking at a bin from 94 and there are still subtle differences between the two. the line pressures for the 4l60e are alot higher in the 2 bins I've looked at so far. should I use the line pressures from my bin or the ones from 94, or does it really matter? my trans has been rebuilt and my transmission guy said we increased the line pressure mechanically so there should be no need to mess with it in the tune. if all goes well I might be able to start wiring the fans in this weekend and see how this goes.
I say if you like what you have now then use that line pressure, but don't mix and match the different trans setting, I tried that once and it didn't work so well. If you can, try to find a $0D bin thats close to yours.
I agree and have done the same thing. Ended up with a hot tranny cuase at highway cruise speed it was shifting back and forth from 3 to 4th gear and didn;t even feel it.
One good option is to 0 all shift times. Firms up shifts and drop tranny temps.
thats what I kind of figured. the bin I found had very little difference from mine, I've copied or verified all the settings from my current bin to it. IDK how well changing the shift times will work for my transmission since its been modified to shift hard as it is. even going into 4th will give the truck a jolt on the hwy. now I need to find some solid state relays.
If it's already modified I would leave them alone, you have nice firm shift points already.
My Buick Roadmaster Wagon has an LT1 and 4l60E and I took a Cadillac RPO option V4P bin which was towing option. Had many changes, I tried to do ones I thought important and ended up with the 3-4-3-4-3-4-3-4 constant shifting on highway and noticed trans temp rising so headed home and even got a trans temp error code, trans temp dropped when in town. So I used the entire bin and made my engine tune changes. What a difference in driving felt more performance or at least like a truck. Will spin tire when shifts to second on wet road.
Then looked at Camaro or Transam that had a switch/button to push for performance shifting. Noticed my bin had that option but switch not wired into car. That table was all 0s, so I changed my regular trans shift times to all 0s. Nice firm shift points. Stock it was like one long slush gear and had no feeling whatsoever. Just what a Buick Roadmaster was designed for... yuk! Tranny temps dropped by 10 to 20 degrees, 20 in town and 10 on highway.
now would this code be able to run this relay set up for a set of dual fans in a camaro from a 427 ecm. i understand that the power wires would need to be either ground or hot which is no problem. if i remember correctly it turns both fans on low for the first stage of temp. then on high if needed. i dont have a/c.
