i have a k24a4 swapped in to my 08 civic si coupe. car starts fine idles a little weird and at about 3800 rpm is hesitates like missing or calibration is not correct can i up load a k24a4 base map to my k20z3 ecu using my flash pro and if so where do i look for ecu re flash for the k24a4 or what can i do need help and any advise would be appreciated. car is running the k20z3 ecu as it has the stock key car will run fine over and under 3800 but if you sit at 3800 it acts like its not getting the correct readings from sensors someone please point me in the right direction....

There is no calibration specifically tuned for that vehicle. You will have to start with a calibration you already have and tune from there, or look in the Vault to see if anyone has uploaded something similar to start from.

There car was swapped to the k24a4 and never tuned it didn't have flashpro till last night when I bought it. Do you know what I pull up on the flash pro that would be close to a k24a4 and start from.

You will just have to try different calibrations to see which one gives you the best starting point. It will need to be tuned though.
