Hi friends,
I want to share my personal DIY experience for engine optimization. I am so far from any mechanic for concerns because i believe its rarely you can find educated able understand sensors values and optimization tuning. infect you never have engine check light until sensor's worst condition while in between wrong information to ECU causes performance and fuel average issues without engine check lights ..
I have Toyota Platz 1.0 L. model 2000. when i have purchased fuel average was worst as 12 km / L. I start work engine optimization, and now reached upto 19-22 km per litter. (City drive). in my last long drive Gwadar to Karachi i have also manually check average with irani petrol with AC at speed between 100-120 i have found 19 km / liter.
here the snap short attached for my din ECU data of min car din panel , AFR at optimal, average at 20 Km/L.
you guys are welcome to ask issues , ill try my best to answer and help out.
Regards,
Asad
