@SuperDicq and like, I was considering welding the diff but, i'd like to park normally

@SuperDicq i might get a 240 someday to drift with, i'll really tune it up, maybe I'll get a Penta motor and swap it in there. welded diff and everything, some other mods. I wouldn't turbo it I'd prefer no lag between my foot and the car

@meso@new.asbestos.cafe I personally don't like turbo Miatas either. I wanna put ITBs on mine eventually when I got the money for it.

Definitely not doing that on this motor tho. I got a spare engine lying around with a lot less kilometers on it so I think I will build that one if this one shits the bed.

@meso@new.asbestos.cafe I don't know if they make ITB kits for a Volvo. Probably not.

For like Miatas and AE86s all the Japanese guys put ITBs on them. Turbos are for baka gaijins who don't appreciate a well tuned naturally aspirated engine.

@SuperDicq hmm I'm looking at ITBs and I'm trying to figure out how they improve performance. on a regular throttle body it only has one inlet similarly sized to the 4 ones in the ITB right? that'd mean it gets a ton more airflow in?

@SuperDicq I assume the ECU would adjust the amount of fuel going in automatically to compensate for the leaner mixture right?

@meso @SuperDicq ECU's do in fact automatically adjust the fuel-air mixture, but the stock settings probably to only expects so much air and/or fuel and may need adjustment.

@Suiseiseki @SuperDicq I know there's some libre ECU stuff but I wonder how hard it is to get it working on my Volvo

@meso @SuperDicq I'm not sure if Speeduino is free, as their websites are absolutely proprietary, but it'll probably work unless digital handcuffs get in the way.

@Suiseiseki@freesoftwareextremist.com @meso@new.asbestos.cafe The Speeduino has free firmware but the only issue is that in order to tune it you probably need TunerStudio which is proprietary.

I mean in theory you can write tuning maps without it with just a text editor but that's not really realistic to do.

TunerStudio is a .jar application that should be easy to reverse engineer tho. I thought about doing that once but obviously couldn't be bothered to actually go through with it because it's way too much work.

@SuperDicq @meso If I was to use Speeduino, I would just hand edit the tuning maps with a text editor, no matter how difficult it is.

But really I don't think there's much more performance to get out of the current engine (I can only accelerate so hard anyway, otherwise the tires just start slipping) and I can just redline if I want more.


Instead I would probably make GNU/Car, with free ECU software by default.

@Suiseiseki@freesoftwareextremist.com @meso@new.asbestos.cafe Honestly if you want a real GNU/Car just buy something that has a carburetor and no ECU.

@SuperDicq @meso You can get an engine that's not too heavy and delivers at least 500kW with a carburetor?

@Suiseiseki@freesoftwareextremist.com @meso@new.asbestos.cafe Why do you want 500kW?

@SuperDicq @meso It needs to be able to hit 400kph (for the meme).

@Suiseiseki@freesoftwareextremist.com @meso@new.asbestos.cafe Yes but that imagine if from "Geoff" the home made car from Top Gear. It did not make that much power. It is an electric car with the motor taken from an airport luggage truck.

@SuperDicq @meso Yes - the pictured car doesn't even make it to 60kph, as proprietary physics gets in the way.

With a ridiculously powerful enough engine plus some modern electric motors and batteries and a bunch of wheels (to lessen the load on each one and to enhance handling), I reckon you could make a nice stiff steel box with terrible tolerances go that fast if you don't mind it being totally uncontrollable without free software constantly adjusting how fast each wheel is spinning.

@Suiseiseki@freesoftwareextremist.com @meso@new.asbestos.cafe I like how you're so GNU brainrotten that you call everything you don't like "proprietary" including physics.
