This is so silly!

New modern ECU's are far, far more reliable than 20 or 30 year old designs - fact. No one can argue modern manufacturing of electronic components - ic's, memory, clocks etc.. are far, far superior as better design and manufacturing techniques advance.

Let alone the advancements in electronic hardware are the HUGE advancements in software for modern management systems.
Why would anyone want to program with hex? ff ff ? 8 bit processors? Why?
New management is far easier to map, make changes, and monitor engine parameters.
No one can argue with that either.
