55p Motronic 1.3 PnP

Post by kon »

I've been working on a Plug and Play ECU solution for cars fitted with a Motronic 1.3 ecu.
I got my interface board from jlcpcb which was designed around reusing the OEM connector and housing. I never liked the OEM case since it's held together by bending the lid's tabs, which easily break after bending them a few times plus connector/case harvesting is no fun.
An alternative is getting the Yanvar/Mikas cases but they were only used in Russian cars and the board is apparently pretty small.
Then there's still the issue of not having enough pins on the 55p connector for additional IOs.

So what i did now is designed myself a case around the TE 55p connector which is readily available. It has an additional 26pin TE connector which will be used for things like wasted spark, CAN, ETB etc. The base plate is lasercut aluminium (sendcutsend does that for <15$ qty 1). The rest is 3d printed, the riser in rusEFI orange PETG and the lid in CF enforced PETG. Held together by 4 screws that thread into the base plate. This is an early revision still and there will likely be more mounts for the interface board. MRE's USB connector will be accessible too (can we get USB-C?)

I'll release all the files once I've fully assembled the first case.

That's come together really nicely.
Now keeping MRE and Proteus in stock in the UK, PM or slack for details.
