Can you please add link for the robotics parts , thanks

www.gobilda.com/ is where I found the parts I used.

do you think i could do something similar to avoid an ECU swap? i want to run ITB's on a BMW M54 engine, but swapping ECU is illegal in my country my thoughts were to do something similar to this with an OEM throttle boddy, and then just have the car re-mapped let me know if you think that might work or if it's stupid and i should just go standalone nobody selling M54 ITB kits had drive by wire support, all of them say I need a standalone ECU, and my car is a pull over magnet as it is, trying to avoid having the damn thing impounded

I guess I'm not sure what you want to do... you want to put ITBs on an M54 but keep the original vehicle's ECU? If the ECU you are using has a MAF, you might be able to do it since measuring or estimating airflow is the ECU's main job. Are you able to remap the OEM ECU or is that not a possibility? If your ECU uses MAF and you can remap, I think you could do it. Your acceleration enrichment is going to be very different using ITBS vs a single throttle. Now for the throttle body motor... opening 6 throttles is a lot more work than opening one throttle, so there is a possibility that the motor could draw too much current. depending on the ECU that could mean burning up the motor driver chip or having it shut down. Originally I had a small throttle motor driver chip, and while it worked it couldn't fully open the throttles. I ended up winding my own throttle springs to lighten the load. I was able to open the throttles all the way but eventually that chip failed and i installed a driver chip like this: www.pololu.com/product/1451. This has way more capacity than I need, but thats better than not enough.
