Series 1 LM1 reading x10

alexj · Post by **alexj** » Mon Oct 01, 2007 4:48 am

I've hooked up nistune to my old LM1 series 1 (the old serial port grey box) with a old belkin usb serial converter - seems to work fine

Only one issue: the AFRs read x10 so instead of 14.7 you get 147.0

any thoughts?

It may be worth checking what the multiplier is set for the AFR in the logworks software for that channel

I believe we mulitply AFR by a value but need to double check when I get back to Adelaide (currently elsewhere at the moment). The unit we tested on reported valid values when I last checked 0.9110 in the test release folder

the LM1 is setup as per the original innovate install (i'm not sure where i'd look in logworks to change that)

would it help to have a screen shot / log file? though the AFRs would be set at 20 (fresh air) as a can't be arsed to get under the car to screw the lambda sensor into the exhaust

any more thoughts on this matt? i cant see any settings in the LM1 software for this.

prob as it is now, is that you cant see the third digit on the 3d trace display in nistune and obviously theres a bit of a diff between 12.9 and 12.0 AFR

Sent myself a note to have a look at this

Is is possible for you to generate a debug log at all for me to look at ... this will show me the raw -> display conversion performed

Is log works LM1_02 setup as AFR (as pictured) or as O2 Lambda?

The log file that you produce should give you sample data

Running with the sim ... the Sample is between 0 - 1024 for AFR. It gets multiplied by 14.7 (AFR Multiplier)

What is the sample value that you are seeing and at what AFR?

OnNewDataMts(1): Using simulated inputs
Current input: 0
Func: 0
Sample: 410
AFR: 13.377000

Unfortunately I dont log the mutiplier so this wont be printed. I've added it for the next test release to print out

Also please confirm that you have your log file directory (File-Configuration) pointed to the Innovate wideband subfolder
