It allows users to make small changes to the code, such as increasing the boost pressure of MFD, enabling sports sensors, and enabling g-force. How to run standard auto/manual coding for modifications, for example, PDLS+ or converting Xenon to LED. In the engineering version, there’s no V (after-sales mode) or P (production mode).Development has most of the development features but not the full development mode. It doesn’t have manual coding without rules, so you can’t make the small changes as mentioned above. However, you can use it to add things using auto/manual coding rules like PDLS+, lane-keeping assistance, speed sign recognition, cruise control, etc.Both versions have all other features like troubleshooting guidance, vehicle maintenance, VAL, fault codes, diagnostics, programming, etc. The only difference is the lack of manual coding without rules and no V or P modes.Switching between the 42.4037 and 38.3 programs is done in the exclusive shell of the Porsche PIWIS TESTER.
