Ok. Yes 10k resistor removed for datalog. Were you able to get the Ostrich working as Dave W alluded to? Start here:http://www.gearhead-efi.com/Fuel-Inj...-data-Tutorial!

Interpolating...let's just say if your spark MAP has rpms 400, 600, 800, 1000, 1200 (fictitious rpms) and you find one that someone claims this spark MAP works well but only has 400, 800, 1200. The in between rpms you're going to need to interpolate the values and at best guess would be average of surrounding cells. Hope that makes sense.
