Gold….simply gold of information here.

Mr. High Ground, your videos are awesome 👏

But what happens if there is an electronic break in a bad ECU/module and the throttle stays stuck open at WOT? Is there a backend monitor that will cut fuel or retard spark to reduce torque since the airflow is uncontrollable?
This is the world of “Torque Security”…

This is why oem manufacturers have a primary and secondary apps sensor, there are two apps circuits in the same sensor. Oem setups compare readings to each other and so does haltech. Haltech also has a monitoring curcuit that error checks the apps signals constantly. Which is why Haltech requires apps 1 and 2 to be on specific inputs, they can't be wired to a different input and still function, you aren't even allowed to select other inputs in the software. Haltech put up a video explaining all of their failsafes built into this type of setup. My old chevelle had a stuck throttle cable causing it to get stuck wot, so even cable setups can fail. Given, it was older, but still. Comparing an aftermarket cable setup to a drive-by-wire, I'll take drive-by-wire anyday lol, as long as it's controlled by haltech

@@LegitRaceCraft This sounds like a sensor check failsafe but what about an electronic signal in the module that “breaks” or freezes (much like a computer screen) where the torque request is frozen at WOT? Basically, is there another RAM area of the ECU that monitor the functional/base layer of the ECU that actually controls the inputs/sensors and outputs/actuators?

[@LegitRaceCraft]

@@755hp yes, haltech has a dedicated monitor thats sole purpose is to perform error checking between the two apps sensors functions. I believe they call it a "supervisor processor", but it's been a while since I read up on it. You should check out some of haltech's videos on this, they talk about the safety features. As far as the ecu "freezing", these really don't fail very often at all. They are highly reliable, so the chances of it freezing aren't common

Are you an OEM calibrator by day?

[@LegitRaceCraft]

No, but I did go to school for this stuff
