it's a degenerate case of a current mode switching regulator - it's just freewheeled PWM through the solenoid (solenoid itself is the inductor in the buck)

Re: 1994 supra with uaEFI
RPM updates once per engine cycle, unless the option "always use instant RPM" is selected in the experimental settings. I've endurance raced on that setting so it's probably fine to use. MAP updates once per cylinder, since it averages pressure over an angle window (configurable with the M...

Re: Maximum VE vs Logged VE
The overflowed value is not referenced by anything internal to the ECU, it is just a logging issue. Fix whatever is going on causing VE to need to be so high.

andrey you should go look at the call to getMax31855EgtValue in status_loop.cpp and see if the things done in getMax31855EgtValue are a good idea to call from an arbitrary lua call stack

Yeah, you can log stock soi/eoi, just copy that. Also try to log stock fuel pressure, then copy that too. That should help a lot, as those tables are optimized for "don't explode the engine or have bad emissions" above all else from Hyundai. edit: for reference, my focus ST would target 14...

Unfortunately it's an ethanol vs. hydrocarbon sensor, not an ethanol vs. water sensor. Water or methanol contamination make it read off scale.

Looked over your schematic. I have a couple questions/concerns: 1. Some of the triggers that the max992x has trouble with are "single tooth per cam rev". That means they could be as slow as 4hz input at engine idle speed. Your peak detection circuit doesn't work below idle speed on a 60-2 ...

Re: Update ECU definition from internet seems to be broken at least on Windows
So it is just for TS, but it's still a risk. TS is using that file for downloading updates to TS, which then run as administrator on your PC. So you've now installed a CA (if only to TS) that can serve files that are expected to grant admin rights.
