Was just talking to evil about a potential replacement for the MPS and came up with the following question:
Is it possible to replace the MPS with some sort of chip / solid state component that emulates the readings that the MPS gives off throughout the range, but is instead driven by engine RPM, throttle position, etc? If that wouldn't work, why? I don't pretend to know much about djet, but it dawned on me that I could program a chip that maps various readings to the rpm range. Might take a bit to get the curve right for part throttle response but...is it doable? |

Read my blog. One of the earlier posts discusses this. The short version is that by the time to put together the electronics to emulate the MPS, you're 90% of the way to a full fuel ECU, so you might as well just spend the much smaller amount of money on a Megasquirt, which uses a solid-state pressure sensor, and thus doesn't need the MPS.
