Immo related tools will read and write them since they are designed to clone the BCms to copy security/key data to other BCMsMind sharing where you saw that the bin file can be read?? I'd be interested in something like that..Yes, any 2019+ GM BCM, I'm aware that there's a way to read the bin file, but I don't know if there's a checksum, seed/key algo, where should I look at so I can free the speed limiter

The format is probably broken in this, but 1st file should be the left side, 2nd file should be the right side, so the file name is critical to reference when you want to try to understand the why something is different for example.Differences between:
First file: "grandambenchoriginal.bin"
Second file: "grandamsealphaoriginal.bin"

viewtopic.php?f=28&t=8183 the bins moved over here. They are different in a few ways. Antus describes them in a language you'll understand. I tried opening the se bin in univesal patcher and couldnt, i then wrote the xdf and was then able to see it in tunerpro but not in tiny tuner. I dont know the exact steps to see side by side (if that is an option in tunerpro) the comparison between differences. And i chaanged the vin on the gt to match with the se,,the car wouldnt crank or go into relearn security mode. The only way is to physically swap the bcm eeprom chips or take mine off and copy it.a bin file means it's binary, aka raw data. You can compare bin files with any type of program to compare binary files, they normally display the contents as hexadecimal (16 based, aka 0-9 and A-F).
The actual tune data location might be different between the two though so that route might not work out the greatest. A better route would be to load the bin into a program that's designed for changing the tune on cars like TunerPro (free), but that software requires another file called an XDF which basically tells the program where to look for the different data items in the bin file. Universal patcher (also free) can open the bin files and attempt to pull the tune data and such. I think it auto detects the locations based on some pre-defined rules, effectively it creates the XDF on it's own. This is the software I used to poke at my car's data before. Can modify and save, but make sure to backup the orig bin files and label them well so you can always revert back to stock. In fact if the hardware is all the same, you could read the bin off the GT computer, put it on the SE computer and then the GT BCM would sync to both computers. Should be able to find the VIN in there pretty easily to make your GT computer match the SE VIN so you can use the SE BCM assuming it's the VIN that it's looking for.
The actual tune tables I haven't gotten into much, but in theory should be able to at least compare them one by one. I'd target something simple like the ignition timing table since that can make a pretty big change on how the engine responds.
I'd also be interested in hearing if there's any difference. I'm sure the numbers won't match 100% exact, but just 1-2 off here and there probably doesn't do much, if it's advancing lower in the rpm for example and it's consistently 1-2 higher in one area, then I'd say the tune is a bit different. I don't really do much with tuning, so I'm probably not the best resource for looking at the minor changes and knowing if it's enough of a change or not.
Another big table is the VE table, basically air vs rpm vs fuel if I'm thinking right. That table should effectively mimic the torque curve of the engine for where it fuels more.

Please let us (me) know what, if any, differences there are.
I'm going to be reading the bin file today off the se, so hopefully I can compare them. I cant wait to be able to write the tuned files...hopefully it will be soon.

For the TRD supercharger for the 1mz camry v6 engine, it's legit bolt on lol, doesn't even need anything done to the computer.Those toyotas can get mean by their potential...i've only viewed one supercharged grand am on youtube and the amount of MachineWorks is crazy. Picture a long cylinder with bearings cutting across the entire front of the exhaust manifold. It reaches all the way over to hit the pulleys from the left side of the engine to the right. It's only 3 cylinders worth of manifold but line up has to be perfect.

There is no difference that I am aware of in any of the tunes of the various 3400 engines. The difference is in the intake and exhaust diameters (the SE has 1 7/8" tubing and the GT uses 2 1/4")Don't really know much about the GT's, but of my understanding, all of the 3100/3400 engines are effectively the same, just the 3400 is larger displacement of course.
From google resultsso there's 5hp difference, probably so little difference in the tune you'd never feel it.A 170-hp, 3.4-liter V-6 engine is standard in the SE2 and optional in the SE1. A 175-hp Ram Air V-6 with cold-air induction and a lower-restriction exhaust system goes into the GT and GT1 and teams only with the automatic transmission.
I'm a bit of a Toyota fanboy, but the 1MZ 3.0L camry engine (not a sports car at all) puts out around 190hp and is quite a lot smaller engine, 6 bolt main, 10.5:1 compression =).
For the coolant thing, sounds like it needs to be burped and get the air out of the system.
Scanners read things differently, normally you have to tell it the vin digits and then it picks that stuff up for trim and such. Pretty sure it's just reading the vin number in the computer to flag it as a GT or not. In the computers I've been into, there's only 1 location the VIN was stored.
Fun little side fact, the older Grand Am's from the early 90's with the quad 4 2.3L 4cyl engine had an option for a high output that made 180hp, more than that 3.4L and a whole lot smaller. Those things zipped around pretty nice with the standard engine in them (160hp if I remember right). Trim names are basically just marketing jargon, just something to extract more money out of the buyer in some cases. Like Toyota is guilty as well with their "American Edition" aka base mode car with a dealer installed security system.
Anyway, not trying to bash your car or anything, just I'm not really impressed with GM's, even the newer 3.5L doesn't make that much more power (200hp). That's more of the American way though, make the engine bigger and that's the cheap/easy way to make more power. Power scales with displacement lineally, aka that 2.3L 180hp engine scaled to a 3.4L would be 266hp if all else was equal. Less power generally means more reliable, so fair chances that's why they don't push the power too much.

No, it Read the PCM and wrote the file.I think you're the one with a wand after everything you've done for me.... you actually wrote a p04 bin!Whip out your wand and get it done!
-Enjoy
