Engine management does not seem that complex, especially how the apexi VAFC system works. I could use a spare M68HC11 E series as a piggyback with some LEDS and an LCD. A month or so of programming and I have something comperable for 100 canuck bucks. What I need are some nice voltage air pressure graphs for a MAP sensor and the duty cycle tables for the injectors. I don't have the cash for an oscilloscope so documents would be nice if someone had some. I'd share all my results on the board and I would prolly use this for a term ISU project, so it's all good.

Any help is great with voltage nfo, thanks.

Sorry I want the Manifold Absolute Pressure graphs, not the ignition or injection maps, Those will still be calculated by the stock honda ecu. I want to fudge the MAP sensor inputs to readjust the fuel and ignition.

Thanks tho.

 

They're linear sensors, 0v = 0psi absolute, 5v = max reading (ie 2bar for a 2bar MAP).
Here's a couple of sites anyway:
