Do you want to be able to fit and tune programmable engine management, working from home? You can! This book covers the selection, wiring and tuning of programmable ECUs, all done without access to a dyno and with a totally hands-on approach. From the step-by-step of tuning idle, throttle enrichment and high- and low-loads, to tuning for best fuel economy. Mapping exhaust gas recirculation for better throttle response, to safely retarding ignition timing with increased intake air temps. PID tuning loops explained in easy to understand language, directly measuring the crank reference indicator position, and how Lambda numbers relate to air/fuel ratios – they’re all here. And if you’re just starting out in this area, there’s also coverage of the fundamentals of engine management systems. There’s even a cheap and incredibly effective tool that you can build so that you can hear when the engine is detonating – or even close to detonating. This compact book is must-have for anyone tuning programmable ECUs.
