ECU live Mapping - All Lancia Delta engines: We highly recommend to live map on every single of the listed steps. Every engine is and reacts different due to wear and tear. We've developed a Plug and Play programmable ECU with Loom setup, please contact us for further informations

Step 0 🏁 - Baseline Check: We highly recommend to check your engine health by doing a "Leak down test" not to confuse with a "Compression" Test. The first one will allow you to do a real due dilligence of your current engine status. Allowing to see any of the possible culprits and determine if or any further engine building steps are necessary. All the following steps are designed based on a healthy engine. Start Clockwise and follow the single steps, have fun, got any questions? Don't hesitate to contact us via eMail
