map sensor cheating?

[decryphe]

If you want to keep running the stock ECU, a piggyback that converts the sensor signal according to some custom map would be the way to go. If you're into electronics, you could try doing this with some form of Arduino or other small microcontroller. Personally, I'd go for anything that can run Rust, as I don't like C on embedded, such as https://www.waveshare.com/rp2040-zero.htm and either breadboard or design a little PCB to do the voltage conversions and some voltage spike protection on all pins.

If that's not an option, you'll have to jump to an aftermarket ECU now.

I could imagine there's also some form of analog circuitry that you could use to adjust the sensor output signal, maybe some form of pull-up resistor could help, depending on the polarity of the signal. I'd have to oscilloscope that sensor to know.

But to me, it's quite interesting that it could be quite simple to slap ITBs on mine without swapping the ECU... I'm surprised it runs at all. What does the setup look like?
