Every application below is pulled from the ECU-to-engine relationships in the portal catalog.
Available work depends on the exact vehicle, engine, ECU software version and the original file you upload. The list below is generated from calibration options associated with Delphi HD J1850 applications in our database and may include performance, diagnostic, DPF, EGR, SCR/AdBlue, OPF/GPF and other ECU-specific functions where they are actually mapped.
Communication method can differ by vehicle, ECU hardware and software revision.
