problem with fuel consumption..(Ecu maybe)

[myupgrade]

hi guys,

I own a Honda Civic EK which previous owner had installed a turbo on it. The piping was set at 2.5 inch (normal for a turbocharged engine) and I was not realized (silly me) on the diameter.

I normalized my civic (uninstall the turbo - only B16a) and have it tuned to get more milage. However, I completely forgotten about the piping size until I went for a regular check.

Quickly, i changed the piping to 2.3inch, but surprisingly, my fuel consumption went crazy..even for half tank, I've a\only managed to get less 200km without activating even 1 v-tec!

does the mapping of the ECU corelate with piping diameter adjustments to create such problem?if yes, why?

please help

bro, how about the injector and fuel pump? is it stock one or already change to bigger injector and bigger fuel pump. normally turbo car have bigger injector and powerful fuel pump which NA engine dont need it and this bigger fuel injector & powerful fuel pump can drink ur fuel like a thirsty camel. u have to tune your ECU to work well with all the engine parts now.

yup,maybe he tempered with the ecu already.try n call the guy up n ask
him what else did he do to the engine.it's a lot more easier then guessing.

to save time and $$ just tel and ask the ex-owner. if can try to undo all his turbo bolt on project at the same mechanic.

b16a is born to be agreesive engine. no ubat or tunning can save him.
use the stock extractor with stock muffler with stock air filter.
and everything stock.
should be the most fuel saving state now.
