MAF voltage = 100% IDC when???
Posted: Sun Jul 08, 2007 6:49 pm
So I finally was out this AM metering the output from my MAF sensor to see where I was before throwing a FCD in.
I found that I am getting max 4.65v at the top of 4th gear (about the same as I see at the top of 3rd).
Once my FCD is in, how far should I push the voltage output?? Can I add boost until I see 4.75v? 4.8v? 4.9v?
I know that the warm summer air will yield lower outputs at the same boost levels, so I will be revisiting this once fall hits and deriving "summer" and "winter" boost levels that are safe for the stock fueling system. I was just wodering if anybody actually knew when the ECU will throw the injectors 100% (i.e. will it go 100% before 5.0v)
Thanks,
Chad
btw, altitude changes these readings dramatically (duh). My 4.65v is seen at 12-13psi (still 11+psi at redline) here at 5500ft asl. I think I can run close to 15psi and still be <5.0v. This is on a VF12 (3" CES, A/W IC, etc).
