ok my jay car kit is assembled but problems with the wiring!
I'm using a 4 pin o2 sensor
white - (continuity between both white wires = heating element)
white - ^^
grey - earth (continuity between grey and o2 housing)
black - signal
for the jay car gauge theres 12v, IN (signal) and earth
if i earth out the signal for the gauge, gauge shows 7. if connected to the o2 sensor. it shows 22
um help please?
edit - i connect the signal wire to the gauge and sprayed the o2 sensor with brake cleaner, value didnt change
-------------------------
orite Ive got 4 o2 sensors (3 wide band and a narrow)
threw the narrow in, went for a drive.
showes...
10:1 under full load
drops down to 9.1 when the gas pushed to the floor (accelerator pump)
released the gas at 100kph, dropped down to 8.5 then crept up to 9.5
* i have a miss at idle when i push the brake pedal, so pumping the pedal at idle = 8.1:1 *
with the choke on at idle 10?
i tried another sensor and got the same results
NO wonder i chew through fuel!
