Anyone need patches? I have been working in hew and have been modifying patches to work on other cars, send my your rom info and car info and I can make a patch. There are some issues with it sometimes the CEL blinks or has weird codes, but working on fixing those issues. If you want to be apart of this project let me know.

I have a 2013 sedan STI USDM - AE5L500V and have been dying to patch my current map but unable to because I am failing to download and run HEW and GNUSH..

I edited this to add the rom. I see you responding to another person requesting almost the same rom as me. Must be the 2013's finding new owns in 2025. lol

Here Is a patch modified for your rom, It will say a different year but I have changed the important hex values to make it work, I am new to this so it may have weird things like cels that done exist or something but hopefully there is no issues with it.

i've noticed some email providers are not yet supporting TLS for their mailservers which they really should so if your not getting any alerts from the forum that's possibly why.

this means that with modifying 000FF8 - 001000 area and proper tuning all 68 roms starting with AZ1 from here https://romraider.com/forum/viewtopic.php?f=35&t=7591 can be cross flashed
or all 44 roms starting with AE5 can be cross flashed

so you can use AE5IB00V MerpMod patched rom below on any AE5 rom in theory

*USE WHAT I WROTE ABOVE AT YOUR OWN RISK , I did several cross flashing tests as described above but I did not test all possible combinations ...

I saw a hint from andea79, but not sure if to try it right away.

STI
Market: USDM
Year: 16
ECU ID: A62A907107
Internal ID: AE5T201V

***UPDATE***
- Copied that ff9-ffd part from mine to AE5IB00V-patched, everuthing else is same up to 2000 slot.
- flashed that one in, car tried to start for like 3-4 seconds, started, revved for a sec and wend down again, revs were not shown on the dash, I guess it won't work to just copy-paste from any other AE5 rom, has to be AE5T2***, right?

Can you make an updated patch for 04 STi - A2ZJ710J?

The current Merp patch works works great with speed density, and injector IPW and it has flex fuel but the only flex fuel input is via rear o2 sensor (super annoying) Can you make a flex input for the TGVs as the Cobb kit and most every other flex fuel kit routes thru the driver side TGV.
