Thanks for the fast reply, thats the problem though. I cant write with .ctz or .hpt only .bin however i cant tune a .bin file for my car opensource

Is there any way to convert a Efilive .ctz or Hptuners .hpt file to the Ecu .bin file format?

So even if the OS is supported, in my case its not possible. There is no way i can change every single table from the 04OS to the 03 os just using tunerpro.

Im curious if anyone knows about maybe disabling the DBW area in the vehicle options table? because even the vette has IACV tables. I also know some chevy express vans used OS12587604 and they were...

The vehicle is a 2004 Gto with the oem computer. Im not looking to change to DBW nor looking to change the computer.
I appreciate the xdf however i can tell it was generated via universal patcher...

Thank you for your help it was very informative. So I'll have to wait on doing an OS swap if its even possible. The easiest way would probably be save up for hptuners

Im not looking to change my PCM. If what im asking about (changing just the OS) is not possible than I'd rather live with my pcm and os

Thank you for your help I really appreciate it. However im not sure how having to modify the wire harness is easier than flashing the 04 vette tune. Correct me if im wrong but For some reason it...

Ok that makes sense, im not looking to change my pcm though. Just change the OS to a more tune-able os.

Thanks for the info, the corvette bin that was provided is actually hardware number 12583659 so it should work with drive by cable and appears it does have iacv support

no luck :( still a new program.

Thank you everybody for all your help. I feel a bit overwhelmed now to be honest. Only reason i wanted to change os was to br able to tune my car since my os doesn't have an xdf I don't believe idk...

Ok interesting, so than it shouldn't work. Which is interesting because in the 04 vette file i have, it shows dbw in red like my gto, and it also has filled in iacv tables. I was really hoping an os...

Hmm, maybe this is a bit beyond my ability. I read on a github post that the 12587603 should have a m6 ls1 DBC combo correct?

actually it appears from further research that corvette one you attached would work however i would have to manually compare every table and transfer any data from my bin to the corvette one? i hope...

Ah ok thanks for your help, im relatively new to ls tuning im from the Subaru tuning world which is much easier. So i know my car is drive by cable so that bin should be too? I should be able to...

Thank you. Idk what blue or green means to be honest. Tgat Corvette should work i assume? Im not experienced in swapping operationg systems at all. Is it the same tune just different operating system?

As the title states after some research it seems in some cases it is recommended to outright switch to an operating system that is more supported. Im curious if that is something possible to do if...

Sadly no luck in regards to what i need to tune. Still looking for an XDF if it exists if anyone has one for 12587604 for tunerpro.

I wasn't trying to polute the thread i was just trying to get support or make what i thought was an issue known. I will change the original post there is no need go get so defensive i understand it...

Ok, i just tried that. Sadly it loaded the same. I also reinstalled the program. :( I think its just universal patcher not being complete. Like he said 900+ loaded but its lacking alot of key tables...

Im trying to give as much information as requested, above i provided examples of stuff that is Missing, if its the same as other bins than i guess it's normal. For example: Timing, fuel tables, idle...

it is also missing timing table, rev limiter, fuel table etc.

im attaching the bin file, other stock bin for 12587604 have had same results. Im far from an expert but it just seems incomplete. For example the idle table is missing.

Program seems great, however it is not fully opening my 12587604 bin file
