This used Saab Trionic 5.5 ECU is custom-programmed for use with our T5 conversion kit, specifically designed for the Saab 900 Classic. It comes pre-configured to work with our Boost Control Valve (BCV) and 470cc fuel injectors, offering a plug-and-play solution for T5 conversions.
The ECU includes a fully tested and optimized base map that works out-of-the-box on a stock Saab 900 Classic, as well as on modified setups featuring the DO88 intercooler and our KCP Stage 1 TE05 turbocharger.
We strongly recommend custom dyno tuning for optimal performance, safety, and reliability – especially when further modifications are made to the engine setup.
This ECU is a great starting point for anyone converting their Saab 900 Classic to Trionic 5, offering a solid base for fine-tuning and long-term power gains.
