Contact Omex, their help is very good. Give them the details of your car, like injector size, sensor types etc and they will provide you with a base map which should be enough to get the car running. It'll be very generic so the engine won't run brilliantly, but it'll be a start
We were using a Ford coolant sensor which on the original map wasn't giving anywhere near the correct reading. A quick call to Omex and they provided a map with the correct Ford sensor calibration included so the temp read correctly. They didn't have one for the intake air temp sensor so we bought an Omex sensor which worked perfectly as the calibration for it was already in the map.
Certainly worth a phone call
