I am considering buying an old hybrid and converting it to all EV. I was wondering about how the conversion would work with the existing computer. Would it interfere?
Has anyone ever converted a Hybrid to EV?

Your question is too general. In short, yes, it would probably interfere a lot. It would not be much fun.

I am considering the same thing. I would approach it by fitting a second battery pack in parallel, and fitting a plug-in charger.
Keep the ICE generator, until those bits are sorted out. The generator should only run, when the battery can't keep up with the power demand. Drive the car for a few months to see how it performs.
Experiment, and decide how to proceed. Can you fiure out how to unpatch the ICE generator, and still drive? How much electric range do you get? How many kW of capacity will you need? More of the same batteries, or something with more energy density?
Hybrids already drive on electric power. Ultimately, removing an engine, upgrading the batteries, and fitting a charging system sounds a lot easier than a full ICE to electric conversion.

The battery pack and thermal management is the biggest PITA in a conversion, not the electric motor part of it, imo. That said, Damien's youtube channel goes into running a Lexus hybrid sans ICE
Why would you start with a hybrid? In many cases the electric motor would not be sufficient to drive the vehicle entirely but itself, and the battery will certainly be inadequate unless it's a plug-in hybrid. If it's a plug-in... just drive it.
And I agree with jbman: the computer side won't be easy and unless your idea of fun is diagnosing and modifying complex electronic systems without full documentation, it won't be fun.

I have been watching Damien's videos. A lot of the control electronics are beyond me, right now.
I just found Weber Auto, on Youtube. They have some excellent videos on hybrid drive systems. Now, the mechanical side makes sense. Getting both mg1 and mg2 to power the vehicle will be necessary to run at highway speeds.
I'm hoping a hybrid to full EV conversion can be done reasonably simply. Still early days of research, for me.
I agree that thermal management is vital element. That won't be the challenging part, for me.
