I have a eg hatch with k24a2 swap that’s stuck in limp mode. Car was running fine but I launched it and then it died. Found that the ecu fuse blew. I changed the ecu fuse and now the car will not go past 3k rpm. It’s running hondata kpro v4 throwing code po600

 

Download the latest KManager. The reason that I suggest this is that it reports the P0600 error code as 'Multiplexer not present (for engine swaps disable in misc parameters)'

You will need to disable the error code in the parameters and re-upload the calibration to the ECU, open your calibration in the software3 then you must click on the upload button (arrow) at the top of the screen to upload to the ECU.

Your code is for the Multiplexer and its irrelevant to the swap now. You can simply disable this in the parameters.
