heya, i have the same ecu for my 1.6L so it may be different
Air temp sensor reading 100 = bad sensor / Bad ground in 99% of cases this is covered in the installation pdf ( or maybe its the tuning pdf ) try a different ground.remember this reads in celcus not farenhight so arround 50f would be arround 10c, it saying 14 would be pretty accurate in the engine bay as its a little hotter in there then ambient.
"Today I went to start it and it loads, fires and dies."
Make sure ur turning the car on correctly ( lol ) turn the key to the on position and u will hear the fuel pump prime and then a click under your dash, after that click ur right to start the car. what u say above is exactly the same as when u just turn the key on without letting hte ecu boot correctly.
if your not hearing the fuel pump prime and the relay under the dah click ( about 5-7 secoonds wait) try different things with the ribbon cable from the ecu. Latly ive had issues with it. EG
Ribbon cable plugged into serical converter and serial converter plugged into laptop = at key on fuel pump doednt turn on and car wont start OR starts for a second then stalls from no fuel
Ribbon cable plugged into serial adaptor but serial adaptor not plugged into laptop edu boots fine and car runs
Ribbon cable unplugged = edu boots properly and car runs
Just throwing ideas out if the above doesnt work, not sure but if ur map is under 20 u will be under the MAP overrun ammount ( default is 20 ) so it would start then just stall cause the injectors have been shut off, what does this mean? NFI just something to think about. you could try lowering your map overrun setting and see if that helps, but not sure it would be fixing the issue. Also check the vacum hose your using, probibly not it but its an idea.
Good luck hope this helps
