TLDR: Mazda 3 with Honda V6 J30 and speeduino for ECU in parallel with existing ECU

medium TLDR: I bought this weird Honda car rebadged as Mazda 3, I don't know why Honda just don't put it's name on it, Honda Accord 2 or mini accord, or super civical... whatever.

So I'm planning to swap the the K25... or L5-VE thing for a J30 that I have there doing nothing...

Because I'm not dumb.... I bought the car and then check dimensions of the engines...

So there is a slight chance that everything might work... because you know I'm not dumb... first started disassembling and then and only then did all my homework including checking dimensions of the engines, clearance, etc...

I've disconnected most of the stuff from the engine being the last things I need to disconnect the transmission and the engine mount to get the Mhonzda K25 2.5 L5-VE whatever from the engine bay and put the J30 in all it's unused gloriousness inside the bay to see how much the see-saw needs to "fix"...

I'm planning to put whatever it's designed/created as part of the build in this GitHub repo

These images I tried to be as much as scale as possible using images from the internet, I did several measurements and they should be somehow, good enough to scale, there is obvious parallax effect on them so not a perfect match like for example in the bolt holes in the engine/transmission and the transmission image was mirrored
Superpositions are centered using the crankshaft output as aligning item.

Ok, here is the first version of the adapter plate that I didn't bought by mistake too thin.... it's because it was perfect to use the dremel, I mean the beautifying wand and adjust the positions of the bolts.

first version of the thing is around 70 bucks... I'll call it pacman or the highway...... no, not convinced... well something more descriptive... domestic honda to almost honda mazda 3 si...

And the final version will probably be built using the 12mm material
