Let's reverse engineer a Subaru ECU. No, really, let's do it. - Subaru Impreza GC8 & RS Forum & Community: RS25.com

oldhat · 09-11-2008, 08:28 PM

I'm sitting here bored and waiting for spaghetti to boil, looking at a Z4 ECU out of my old WRX.

Let's figure out a way to grab all of the data/ROM off of the circuit board. Then we can see how these brains actually think and work. It will demystify a lot of the ECU voodoo for us and it will be fun. Right?

I have absolutely no idea where to start other than cracking open the case and taking pictures of the board.

Any computer or software engineers? Or someone with training/experience with electronics? Or just a really curious person? Does YesItsDrew still post here? I remember he knows circuits. Also, rob might be good with this stuff.

RS25.com = The Mother Brain. I am 100% confident that we can figure out how to do it if we put our heads together because everyone here is HELLA smart. Who's with me? Post in this thread if you're interested or just want to watch the trainwreck.

Subscribed. I have no clue how to do any of that but ill watch the fun

I think member Storm might have a lot of knowledge with ECU's. I was going to have him make my 97 2.2L ECU have an increase redline but never had the chance to go through with it.

I don't know much about ecu's, but I've designed a few circuit boards, and my stepdad used to do that for a living. I'll do a little research and see what I can come up with...

Count me in. Ive thought about doing some this to some degree for my RHD V5 swap. Utilizing labview seemed the quickest way that came to my mind. Check this project out:

Awesome, it's a guy posting a link like that within 5 minutes of starting the thread which blows me away about this place every time.

What do you know about Labview?

joefitz · 09-11-2008, 09:03 PM

I use it all the time for work! Its basically an engineering controls language, very quick to develop and test.
