that's not true
programs which use the win32 api have no problem accessing the serial port, even when compiled with VS6
the problem arises when a program tries to access the serial port using the 16 bit api remant from windows 3.1 and which should've been buried 10 years ago
so now you know...
ecu schematic diagram
perhaps this is the link you need: https://www.bgsoflex.com/v22/msv22.html
It's not so obvious on the MS page, the "version 3" is only a small add-on board, you have to look for the version 2.2 schematics.
also, here's another ecu project with schematics: **broken link...
high current mux
You could use a high pin count microcontroller and connect each of the zif pins to a microcontroller pin. Then, in software, you could set the power pin to vcc, the ground pin to ground and leave the rest tri-stated so they do not interfere. PICs can supply 25mA in their pins...
Fuel injected cars actually don't have a fuel flow sensor. The fuel flow is computed from the time the fuel injectors stay open so you could tap into one of the fuel injector wires and figure out how long it's open as a percentage. Then multiply that figure by the injector's maximum flow rate...
ecu electronic-control-unit processor
Take a look at:

It's a complete ECU with full schematics. Might be what you want, or might help you build what you want. If this was helpful, please click on "helped me". Thanks.
best compilers for pic
I've used both SourceBoost and Microchip's C18.
SourceBoost is a very solid compiler. Its documentation is clear and to the point and works very well, and works with most pics (10, 12, 16, 18). However, it has one major flaw: speed. It seems that long if-else chains and...
icd0161: verify failed
That error means that the ICD2 did not find the expected pic on the target circuit (i.e., expected a 16F877A, found a 16F877).
In particular, the "read=0x0" means that the ICD2 was not able to read the target device identification, which means that either: a) it's not...
