  • If I buy a b6 ecu and plug it to the b3, will it increase fuel?

    I have the b3 engine with the fms street camshaft a cai and a straight exhaust but with the stock fuel injectors. If I buy a b6 ecu and plug it to the b3, will it increase fuel? The ecu I saw is the B63H.

    no it will decrease fuel. If you put a b3 ecu in a b6 (injector) car that would increase fuel...because the b3 ecu actually duty cycles the the b3 injectors a little longer than a b6 ecu would because they're slightly smaller, So it would hold a b6 injector open longer too. Either go with the b6 injectors on the b3 ecu (richer) or get your hands on both the b6 injectors and the b6 ecu (a little less rich) if the b3 ecu makes the b6 injectors too rich, especially at idle. Look for a b61k ecu also.

      I understand your point and that's what I thought too. But how come a friend of mine had a Daewoo Racer with a 1.5l engine and he put the 1.7l ecu and it made more power. It's true because I ride with him and it really made a difference.

        it probably depends on the application

          So with the above mods I have mentioned do I need to upgrade the injectors or ecu? Because If it is not necessary, I will leave it as it is.

            The other car might have bumped up the timing. Your stock fuel system is fine with a little exhaust, cam, intake work.

              What timing?

                  So your saying that some advanced ignition timing requires to change the injectors?

                      No just a different octane rating on your gas in extreme advance settings.
