"Over time it's not uncommon to see a design get simplified to save cost by reducing the component count. It will still do the same, but with fewer components. That may be the reason why those ECUs share the same part no but are different inside."

Yes, I expect the assembly part number to reflect changes to fit, form, or function making accurate inventory possible. And I think it does generally, with these Bosch ECUs, but I felt they stretched the "function" rule just a bit when the hybrid's reliability was improved with the only indication in inventory being the color of the label.

Thanks for trying the TIP-122 as an injector driver replacement and doing a great job of documenting it. It hasn't happened to me yet, but I've seen several posts describing symptoms of a shorted injector driver. Mostly, I think, after trying in a turbo with different injectors.
