A/F datalog problem

[Bubleguy]

Hi everyone,
i am using innovate LC1 monitor and the wideband sensor that i bought in the same package (one year ago).
The problem is that i see different value on the LC1 and in Smanager.
I know that LC1 monitor can show wrong value if there is a loss of power (volts) (for example : bad wire connection).

I wanted to be sure if the value datalogged by Smanager is the good one and if i can rely on it.

If you cannot trust the LC1 monitor then you have no way of knowing when it is readig correctly in the Smanager software.

I'm having the same trouble here. I have an LC-1 and s300. My voltage on my wideband gauge read 14.7 for example and the s300 reads 11. From the LC-1 i have the analog output 0 - 5v going to the gauge and 0 - 1v going to my ecu pin d14. I have been looking for values to enter into the voltage lambda conversion table, but all examples I have found do not make the readings consistent between Smanager and the LC-1 guage. I believe I have good grounds but maybe I need to recheck.
Also do I need to program my 2nd analog output on the LC-1 that goes to the ecu to output 0 - 5v instead of the 0 -1v? My Smanager voltage readings seems to fluctuate a lot.

Wideband readings should be in 0-5 volts. Make sure you have programmed the controller to output the correct voltages and make sure the settings you input have not been overwritten or erased....we have seen this happen on the Innovative units.

thank you Spunkster
some of this stuff seems like I'm asking trivial questions.
But i guess I need to program both analog outputs to be 0 - 5v.
I guess then my values in the wibeband / lambda conversion ( under the closed loop parameters ) should be as follows 0v = 7.35 afr / 5v = 22.39 / 5v = 22.39 (why are there 3 boxes with the second two having the same values??)
and thirdly my sensor setup should be as follows: switch to AFR to read the same as my gauge under AFR readings. Do I have to change "Display min" and "Display max" which are currently set at .7 and 1.4 (for lambda) accordingly

If anyone has answers to this stuff then that would help my stress and frustration :lol:

i use the LM-2. the manual sais, that it has a differential output, that means that you need a "comparison base" for the signal, a grounded one.

for me there are 2 cables, a lime green one (signal +) and a yellow out (signal - -> ground)

when i connect only the lime green to the s300 there is only shiat shown, while with the yellow cable grounded the messurements are great (just a small offset to set)

well, but i don't know if that's the same with the LC-1, but surely it is :D

best regards,
Luke

Try grounding both LC1 and guage to the thermostat goose neck on the engine, that's where the ECU is grounded. Do a free air calibration of the LC1 sensor. What input are you using for the wideband?. In my case B6 worked best for me.
