Hi seniors wheelers, Hope you are all doing well and staying safe. Guys the same issue I'm facing with my d15z8 single V-tec. Recently I bought this car with a d15z8 setup. My issue is that it's fuel average. It gave me 8 to 9 in the city with a very light foot & with Ac 5 to 6. I searched a lot about this engine and its fuel Consumption, On internet, they are saying that the engine gave 13 to 14 in the city, and long it gave 18 to 19 because it is a VTEC-E, E for the economy. After reading this blog I have checked my ECU and the ECU code is
HZ
37820-p6f-p51
949-1010235
Fan Auto
No CNG,
Manual Transmission
Engine Oil is kix 10w40
Engine condition is good
Now, please suggest what should I do now for its better mileage, I want to ask that how can I know that my V-tec is working perfectly and this ECU is fine with this D15z8 setup or should I need to change this ECU with P2j and please recommend any good electrician or computerized workshop who understands that altered setup and knows how to solve the problem??
