Hey /o/
Is there such thing as a moddable, build it yourself ECU?
Most cars today come with ECUs, and they're a crucial part of any car, but they all seem to be these untouchable black boxes that everyone is afraid of and you never mess with. Plus they cost thousands of dollars.
Is there a build it yourself, moddable ECU that you can program however you like on the cheap? Have any of you tried it?
Kind of like a linux-tier ECU?

Not that I know. You can tune your own ECU though, just search for Cobb's AccessTuner Race if you want an idea.

Is there anyway to retrofit OBD II to an older car?
As in is it just a connector/jack or a box that all the sensors go through?
>>14968298

MS is essentially an open source and open hardware ECU, usually there's specific schematics and code for each make of car you'd stick them into
for instance they're popular with turbo miatas

Interesting...thanks anon!

>>14968399
note; basically no megasquit designs include OBD2 support so don't plan on using one of these for anything after 1997 unless you plan to re-install it for each yearly inspection
>>14968388
neither the code nor the hardware is opensource.
>>14968342
no, not with out the entire ecm
>>14968415
depends entirely on state.
>>14968288
Yes. It's called buy an FPGA and program it yourself.

>reinventing the wheel
By the amount of time and money you would have into a project like that, you would be better off work a little bit of overtime and just buying a Haltech Elite.

I'm amazed in the modern age of computing standalones are still so large and expensive.

>noticing shit like that
>>14968342
yeah but it's such a massive pita you'd wish you never started

That's what I'm surprised about. The technology is in no way complex, and it's been around for ages.
I'm just surprised there's not a one size fits all standard as opposed to everything being proprietary.
it's called megasquirt u TWAT
>>14968288
rusEFI is open source. Never tried it but I think it's the only thing out there. Megasquirt is proprietary now.
Why physically mod an ECU? You can adapt standard ones to do just about anything with an engine, and even adapt the features they control. Other peripherals can be controlled through other means, no reason to route them to a main ECU.

Seems like the new megasquirt boxes do it out of the box

Megasquirt is shit
>>14970523
why?
>>14968288
Yeah man, I have a FB RX running off two RPI 2s
>>14970548
care to give some wiring and software tips?
I'm guessing Megasquirt has the most international support.

This basically allows you to tune and tweak your own ecu.
Originally made for saabs but I've seen lots of vw+Audi's in there as well.
>>14968415
Or you could choose to live in a state that doesn't check for it

>using an FPGA for an ECU
did you just learn what an FPGA is or something?
>>14971818
sssssshh, he doesn't know that regular shitboards like adruino and SJWpi are good enough
>>14970433
only if there was obd2 in the first place
