Milanski Posted April 13, 2022 Share Posted April 13, 2022 I've put myself in a corner. Built custom intake and exhaust system for twin turbo 5.4. So lots of heavy mods. Should have kept the stock fuel system to see whatbthe MAP slope and intercept tables (auf0056 and 61) looked like after the build. But alas i didnt. Now i dont know if its the map zero or map slope tables (56 / 61) that need changing along with the the new id1050x injector data. For now i am keeping the MAP tables stock and dialling in the low slope and offset for the injectors. The i.d. data is have thus far to give me a goodnidle are like 20% different to theirnrecommendation. This would auggest to me that the Map tables need a looking at. The question is, should i continue to tune the slopes in against stock map zero and slope tables OR install the original fuel system along with oem ford bosch injectors and confirm the MAP tables are correct for speed density calculations. This will ensure i have the air mass system functional against good known injector curves. Buy this is a lot of work to revert back and forth.... Ive noted a few tunes going around, mainly supercharger type where the map tables are stock. I get the feeling im playing with a chicken and egg scenario. A point in the right direction is appreciated. Quote Link to comment Share on other sites More sharing options...
