just a thought, as I am still fighting this.
has anyone tried unhooking their A/F gauge?
Im not saying "if I cant see it then it must not be doing it" but that these A/F gauges are "active" and if you dont use both +12vdc and ground then you will be throwing weird signals (ie +5vdc as a NB reading) to the ECU, they are seen by a logger but what if they werent seen?
Reason I thought that might be the case (turns out negitive) is bc I knew I unhooked both my O2's but was recording a normal looking signal from my rear O2 sensor, turns out my gauge was hooked up to the rear and was somehow making up a voltage (even w/o +12vdc going to it) that simulated a working O2!!!! HOW??
Anyway, unhooked gauge, zeros for both O2's.
go for a ride, felt fine at first, then two min later its back.
This time a make a log!!
Im looking at the log and dont notice anything weird,
other that a strang ACLE graph, but mabey its normal?
Its never below 50%, then jumps to 100% when ever TPS increases.
Does that sound right to anybody? Shouldnt it be below 50% sometimes?
I cant upload my logs but here are the ranges of each sensor for the 2 min log.
RPM=1000-4000
INJD=2.0-13.0
KNCK=0
O2-R=0.01
O2-F=0.03
TPS=25-100
MAP=-8 to 2psi
TIMA=25-37
COOL=189'
AIRT=105-113
INJP=1-6
BATT=13.7
ISC=42-67
**VSPD=0-100 ossilation???
FTRL=100
FTRM=100
FTRH=100
FT02=100
MAFS=94-407Hz
**ACLE=50-100 steps???
