“This isn’t 1970 with discrete components and analog signals. ASICs and boards and digital busses are designed years in advance and highly integrated.”

First let me explain that I DO know how they work. I was born into a repair shop, and have owned three successful repair shops over my lifetime, I just recently sold my last to retire. It is what I do for a living and what I have done all my life. I have lived the hands on daily experience of all the changes and advancements in auto technology since the 70s. I have worked with manufacturers running long term test analysis on parts and components out in the real world as a manufacturer certified warranty vendor.

I am a master in both auto and heavy truck repair. In fact my life knowledge and experience in the industry is so intensive I could be an auto engineer. Working with computerized engine management systems when they first came out helped me understand and move into building personal computers in the 80s, I was changing out CPUs before PCs went modular. I’m not just a parts changer, I am a parts designer and have made many custom one off parts for special application including designing my own custom circuit board/component schematics I send off to be built by those with the proper facilities.

Over the years I have built so many race cars for customers I lost count. My crew and I were building custom boards and programming custom boards for racing applications before anyone even had them available aftermarket for that model. So I full well understand how they work. Voltage is stepped down and is simply a carrier for a modified sine wave as the signal that communicates with component sensors that have their own chips.

An analogy would be like using a modem tethered to a PC. Basically a wired two way radio communication system with a separate carrier from the data signal. Like you say, they no longer use voltage or current resistance as a controlling factor like the 70s. That is done remotely in the sensor it’s self before it communicates with the management system computer with that data so it can process it and use it. It could actually all be done wireless if it wasn’t less reliable and a few pennies more expensive to incorporate than being wired. And as you know, it is all about that one penny.

Now let me also explain to you that there are aftermarket parts made for racing applications that can be integrated into the management systems with a simple chip change out even if it requires soldering. Or a computer sandwich plug that plugs in between the existing factory wire loom connector plug and the onboard computer plug. They have remote controls where you can “dial on demand” what you want that engine and transmission to do. On diesel pickups for example with just the turn of a knob you can dial it down for economy or turn it up to make 500 HP if that engine is capable of making that 500 HP. On autos you can adjust timing, fuel, RPM cut out, shift points, Etc. on demand from a dash control. And even that tech is now old school.

Now my turn around with my custom board assemblies were no more than a month. Aftermarket companies can design, build, and program one for anything made within a month. So based on my knowledge and life long hands on experience of how this works, there is absolutely no reason the auto manufacturers themselves could not have done the exact same and have the new custom boards with alternative chips being mass produced, reprogrammed, and rolling into assembly within a month. “The chips themselves are not smart enough to know a difference”. They just didn’t want to...
