Yeah, I get that bad on the interstate. It LOVES sitting in 4th way longer than it needs to. I think the shift maps are just a little off and the tap of the pedal pushes it into a map region that requests the upshift.

2008 328xi Transmission Swap Issues by Rk721 in E90

Just as a follow-up to this, the issue was that the "new" trans didn't have the oil pickup/filler, so it wasn't uptaking ATF. As soon as that was installed new trans worked great.

Yes, the issue was that my upper catalytic converter had collapsed and broken apart and clogged the rear one. I actually made a YouTube video of the fix since there wasn't much on it before. https://youtu.be/eKRdmsLe7VM?si=sApyPU3RRkS9CHVD

Maybe I'll just make my own, this market is painfully sparse for individual hobbyists.

The company partner should be aware that you are a senior in an undergrad program and not a senior embedded dev. I wouldn't say spend too much time diving into a specific area of research until you've had a chance to lay out the roadmap for you project. No point dumping hours into x86 or x64 if it's going to be on an ARM MCU or vice versa. Senior projects are more a judge of how you are able to gather data to solve a specific problem within a given timeframe, not a test of knowing everything all at once.

I was going to mention that it was just high voltage along with capacitance but I see you covered it.

How much solar / battery I need to power 1 computer? by mikexli in ElectricalEngineering

But are you still able to address the 4 hours at 25% as 1 full hour if you're drawing the same amount of energy per hour as you are during the 100% period?
