How to scale the HPFP pressure sensor

[Lex]

Excellent work Dustin - glad you can get the circuit together in 1 day.

EDIT - couple of notes:

I like that you used a high limiting resistor to not load the output of the sensor.

In terms of mimic-ing the 4.6k - 6.8k divider for some sort of failsafe (the 2.92V) - it's probably not necessary as that will be scaled if the pot is anything but 0 and the ECU won't see that voltage value even if the sensor is disconnected.

Yeah, but i figured seeing at least a "scaled" version of the divider voltage was better than seeing 0V, lol.

I'm stoked that it seems to work. Wish i could drive around with adam and the scope now, lol, but we will as soon as i get my new pump.


In the mean time, i was thinking of building up like 5 or so, and letting some people beta test if they want, at their own risk! Haha, can't add enough disclaimer to this, cause it's definitely experimental research at this point.

The 5 wouldn't be beautiful PnP units, they'd be ugly like mine, haha, and require soldering probably. And i honestly think they should go to some people pushing the limits of our power thus far, like socks, and definitely mark if he wants to try. And anyone else really.

I may ask for some money for the time to build them and parts and shit.
