LC-1 Wideband Readings

[X Ray]

I have just installed an Innovate LC-1 Wideband to go along with the Powerlogger and the Scanmaster……after installing and calibrating I am seeing reading bounce between 13-17…..are these normal readings or should this be a more steady readout….thanks in advance.

ECM target is usually 14.7 depending on the chip. Once the car is warm and in closed loop it should stay pretty close to that. Maybe bounce between 14.5-14.9.

On a E-85 chip I think the ECM target is a little lower. Around 14.0.

On cold start you may see 11's - 12's and then 13's. As the car warms up should be around 13.5. Then once in closed loop 14.7

If you are using a lean cruise feature, you will 16's -17's (while lean cruising)

Where did you mount the sensor? Make shure no pre sensor exhaust leaks.
That will make readings go all over the place.

No leaks...see attached
It bounces in all conditions...
No E85...
Thanks again

Thats a little close to the turbo. The sensors don't like heat. Most run it after the bend right before the cat or test pipe. It should be alright for now but might want to think about moving it downstream a little.

Did you follow the LC-1 directions for calibrating? Power on 30sec before plugging in the sensor? Then power off and plug it in. Turn power back on and the controller will run a calibration sequence. (This is done with the sensor in open air)


What are you watching afr's on? XD-16 gauge, scanmaster, powerlogger, logworks?

XD-16 gauge and Logworks software read a digital signal from the LC-1 controller where the powerlogger, scanmaster and a analog gauge read anaolg output voltage.

First need to determine if the analog output is matching the digital reading.

You can do that by connecting to the controller to Logworks software and comparing that to your scanmaster or powerlogger readings. Or if you have the XD-16 gauge, you can compare that to the sm or logger.

Make sure the reading match and we'll take it from there.

1) Thanks for the info ……
2) Yes and I did it several times..Followed directions for first time use..page 8-9 in instructions..
3) Scanmaster and Powerlogger…. same readings
4) I will see what I can do …no XD-16 gauge..

Let me add one more thing that I did that my be adding to this issue….I did not like the location that the LC-1 do to the length of the O2 Sensor cable(or lack there off)…..so I lengthen the wires on O2 Sensor cable by adding a jumper harness with Packard connectors….I added approximately 3-4 feet of wire to allow the LC-1 to be mounted in the center council…..could I have change the resistance to make the sensor work improperly??

Fixed

After making this latest post I decided to make a video and let Rick review my readings and set up…..he was able to help me set up and compare my LogWork3 gauge to the Scanmaster , Powerlogger readings ….. we saw a difference between them, it was suggested that the ground cable be change so it was removed from the Powerlogger analog input block and I grounded it to the body…this corrected the problem I was having with the readings…….I sent a copy of my Powerlogger reading for verification and everything looks good, and my O2 readings are now correct …...THANKS again for all your help….. Next I will be making a shield to protect the sensor….
