Los ajustes de combustible a corto plazo (STFT – Short Term Fuel Trim 🔧⛽) son correcciones rápidas que hace la ECU del vehículo para mantener la mezcla aire–combustible correcta en tiempo real. ⸻ 🔍 ¿Qué hace exactamente? La ECU lee el sensor de oxígeno (sonda lambda) y, según lo que detecta en el escape, agrega o quita combustible inmediatamente. • Si detecta mezcla pobre → añade combustible • Si detecta mezcla rica → reduce combustible Todo esto pasa en segundos, incluso milisegundos. ⸻ 📊 ¿C

While the best method to accurately adjust your VE table and/or MAF calibration is to use a wideband AFR meter, a technique many tuners rely on instead is the fuel trims. In this webinar we’ll discuss the pros and cons of both techniques and see how to set up a histogram to capture the data you’ll need. For the webinar lesson we’ll be using the HP Tuners software on a VE Holden fitted with a 6.0 litre LS2. As always though, the vehicle and ECU is just used for demonstration (we have to use somet
