Why do they run two dedicated wires to each strut solenoid? Why not shared high side?

Looks like you are looking at switching regulator trying to keep constant current through solenoid.
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)

maybe we can connect timing light's inductive pickup to VR input to capture what the timing light sees ?
why bother with a pickup when you can just directly probe the igniter drive signal?

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.

Re: VR + knock module

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 ...

Meaning again same thing: what would be needed to get better than MAX992x.
Or to be better than the existing discrete VR designs that don't use an expensive chip like the MAX992x.

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.
