does it effect A/F ratio in any way?
thanx

If you adjused the voltage down too low, you ECU would never see enough boost to turn your fuel pump to 12V and the pre-spool of #2 could be messed up. Basically if the voltage were very low it would be like running the FFCD off mkiv.com. Seems like it you went slowly when turning the voltage down you would be off by that much, but it might be a good idea to check it with a volt meterZerosoul said:becuase I didnt tune the BCC in with a voltmeter, I just did the quick way driving the car and turn the BCC bit by bit untill I dont hit fuel cut anymore. thas why I wanna know if I somehow over adjusted the BCC and inputs more voltage then necessary to ECU, would it effect how the car performs?
You think that's the "quick way"? It took me 2 minutes with a voltmeter to adjust my BCC to the proper voltage. If you don't want to spend the money on a voltmeter (although I would recommend having one - they are a great tool), buy one and return it after you tune your BCC.Zerosoul said:becuase I didnt tune the BCC in with a voltmeter, I just did the quick way driving the car and turn the BCC bit by bit untill I dont hit fuel cut anymore. thas why I wanna know if I somehow over adjusted the BCC and inputs more voltage then necessary to ECU, would it effect how the car performs?
DO or NOT TO DO the 12V mode? I thought you're telling me to do the 12V mode from your previous post?Marcus Frost said:Goto a hardware store and get a DIGITAL VOLTMETER and adjust the BCC the PROPER way, no more than 4.3V. Do not do the 12v mod.
You also want to make sure your BCC is wired properly, because if not it could also be causing a faulty signal (ie, a vacuum/ffcd signal) which would also prevent your car from making the 9v to 12v transition.

I beleive that the pump always runs when the key is in the on position, just normally when it is in 9V mode you can't hear it.Zerosoul said:Andi,
is it normal to hear the fuel going thru the line even after the car is shut down but with key at ignition-on?
