I don't think thickness matters that much. The connectors are reasonably strong with any PCB installed.
I will order 0.8mm just to save the planet, also 1.6mm looks so last century.
Just a random fact: Audi is placing ECUs inside a cage so that you cannot just unplug a connector. Same break away bolts like they use on steering column locks.
I know, but when learn Eagle few years ago is hard to switch my brain to KiKad. KiKAD is a very good, and free for charge stuff.

Hello from Germany,
I am new to this forum and currently not running a rusefi. However, I am about to fit a megasquirt I had lying around into a road-legal offroad buggy. The vehicle's genuine ECU is a Chinese Bosch ME7.5.7 with this 121-pin connector, here named as "Korean style" version. Well, actually that ECU only uses the larger 81-pin connector, the 40-pin side is blank. My plan is to use the full size connector in a housing of a donor ECU just used to patch wires from one side to the other. This way I can hide my megasquirt somewhere else
Before I order the PCB at SEEED, is there anyone in Europe who already produced a batch of the pcb (and would sell one piece to me) or is anyone else interested?
Cheers,
Maren

The third option for 81-pin female connector is TE 1473244-1:

AKA "Komatsu PC200-8", "60D98D", "60D/98D", "3601115-98D-60D". It's more like "german" type (368376-1) and doesn't fit the "asian" male pcb connector (without modification). Has a "rocking lever" on the top for locking mechanism.
The corresponding male connector is TE 1746979-1:

..Which is visually undistinguishable from the "german" type 1241434-1. Still more tests needed to verify the compatibility.

Here's the drawing for the 3rd connector type (1473244-1 + 1746979-1):
