P0403 & P0443, even after periphery modification
I have a USDM Evo 8 260 ECU running a UKDM Evo 8 engine in my Evo 4. Since this engine didn't come with an EGR system I am getting codes P0403 and P0443, EGR Circuit & EVAP Purge Valve Circuit. I have a 96530706 ROM with TephraMod v7.
I have tried disabling the EGR system by changing FAA bit 11 from 0 to 1 and disabling the engine codes by changing FCA bit 15 from 1 to 0, separately and together. I am still getting the code, any tips?
