Trying to go speed density, I can't figure out the patch, I've tried modifying definitions of already patched ROMS and making my own, I guess I suck at coding. Most of the tutorial posts are outdated and when I follow them usually my software looks different or when I go through the steps something just doesn't work. Does anyone have a video that shows how to make a patch and apply to a 32 bit ecu with merp mod. Even just one showing how to add launch control or something, I'm at a complete lose at this point, I've tried so many things. Also if anyone thinks they can do it for me I will add my current cars ROM.

There isnt a MerphMod for your ECU version.
You would need to look into flashing a rom thats compatible to your ecu and Merpmod. Thats all i know, cant even say where to start.

In teory you can flash ae5 already patched rom...

You can run a patched STI ROM, The AE5 rom in the thread will work, you need to change the map sensor scaling and disable all the ex avcs codes, (or add wires and davcs heads)
