WideBand installation

[blackkarma]

i just installed the innovate DB Gauge on the LC-1 cables and a Bosch LSU4.2 O2 sensor....when i turn it on the guage it does a count up from 0.0 to 15.0...and when i drive the car the gauge just fluxs between 15.0 to 15.1....just wondering if anyone may know what im doing wrong or am i just running really rich.....i had a street tune about 6months ago b/c water in my fuel destroyed my fuel system and injectors....but they tuned it on a narrow band O2 sensor...which i thought was impossible unless using a dyno but i could be wrong

im no expert buy im going to guess anyway. im thinkin that your fine, the result of the readings is because the narrow band is inaccurate to begine with which is why your reading 15.0-15.1, the wideband is a lot more accurate so you may acctually be at ~15. either that or im thinking that it wasn't calibrated corretly.
try compareing the reading on your narrow band to the redings on the wideband

Does it go to around 11.5 when you get on it really hard? My car runs around 15 when I'm not under boost. It fluxuates from around 13.8 to 15 depending on how I'm driving.

 

[blackkarma]

im not sure i will test it out more tonight i didnt really get on it to hard was worried that i might damage something

 

[suprahero]

If you get on it and it stays at 15 while under boost then drive it easy until you get back home and check it out. It should go towards 11.5 or so when under full boost. Good luck.

 

[blackkarma]

alright i took it out for a ride and heres what happen a/f stayed at 15.0, my EGT never rose above 2 and my fuel pressure flux from 35 to 40....

 

[suprahero]

It stayes at 15 while under boost?

 

[blackkarma]

yeah

 

[blackkarma]

no change what so ever

 

[suprahero]

It's definately wired up wrong if it doesn't change at all. Is it installed in the down pipe? I know mine is installed in the downpipe and it is constantly moving.

Wired incorrectly or a dead sensor....

You didn't drop the sensor at anytime did you?

Most WB's will default to 14.8/15 when they don't get the correct signal or the Sensor is fouled.

 

[blackkarma]

mines installed in the elbow maybe i should have connected to the brown wire instead of the yellow to the guage

 

[blackkarma]

Optionally, the YELLOW (Analog out 1) and/or BROWN (Analog out 2) can be connected
to the analog inputs of other devices such as data loggers, ECUs, or gauges. If either one or
both of these wires are not being used isolate and tape the wire(s) out of the way. The default
analog outputs are as follows: Analog output one is 1.1V = 14 AFR and .1V = 15 AFR.
This is
a simulated narrowband signal. Analog output two is setup as 0V = 7.35 AFR and 5V = 22.39
AFR.

 

[IJ.]

It depends on what the gauge is expecting to see as a signal

 

[blackkarma]

after some re wiring....now im reading 7.6 with no gas and 10.4 when i gas it on boost....so i guess it working now

 

[americanjebus]

read the instructions again. Something you wired is wrong. Go through the entire setup process and calibration process again. Those readings are not right. I have the same O2 sensor and i know you have to get your grounds to specification per the installation manual otherwise you'll get nonsense readings like this.

 

[blackkarma]

if thats not right then i will go over it again but ive got everything grounded that suppose to be....did u hookup your gauge to the yellow or brown?

Interesting.
