ECU tuning options for the 1994 Jaguar XJS Coupe

Petrol engines are tuned mainly for Stage maps (where the ECU is supported in our database) plus DTC and readiness handling. Emissions-off is off-road / motorsport only.

How it works

Read the ECU with any tool (KESS, KTAG, Autotuner, MPPS, bench or OBD), open the .bin in Softechpro, select the services above, and the software applies the changes and recalculates the checksum automatically — ready to flash back. Coverage is strongest on VAG, BMW and Mercedes (Bosch EDC15/16/17, MD1, MG1, MED17, Siemens, Delphi). New accounts get 5 free files to test compatibility before buying. We do not offer manual or custom tuning — services are automatic where the ECU is supported.
