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.Last edited by iceracerdude; 08-01-2010, 08:08 AM.97 Aspire w/K03 turbocharged b6 SOHC

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.Originally posted by iceracerdude View Post:festiva: 1995 Kia Pride, 1.3 EFI, manual. :fred:Comment

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.:festiva: 1995 Kia Pride, 1.3 EFI, manual. :fred:Comment

The other car might have bumped up the timing. Your stock fuel system is fine with a little exhaust, cam, intake work.
It's a good thing you don't read the stickies, you might of learned something.
