Q: Does your meter have an analog output?

A: Yes it does. It has two analog outputs usable for a maximum range of 0.5 to 1.523 Lambda (7.35 to 22.39 AFR). The resolution for the outputs is 10 bits 0-5 Volt (0.00489V steps). The Output Voltage over Lambda curves for each output are freely and independently programmable with the included software. See the LM-1 Manual in the support section of our web-site in section 9.6 'Programming the analog outputs' for information on how to program the outputs. See section 11.1 on how to connect an analog output of the LM-1 to simulate a narrow band sensor. Section A.1 shows the pinout and type of the output connector. As shipped, one output simulates a typical narrow band oxygen sensor, the other one is programmed to show AFR/10 for gasoline on a digital voltmeter (for example AFR of 14.7 outputs 1.47V). These analog outputs, once programmed, can be used to drive a closed-loop EMS, to feed a data logging system, or to drive an external display. Very careful attention has to be paid to grounding. It will not work reliably through the cigarette lighter. Optimally use the same ground that the data logger or ECU uses.

7.6 Programming the analog outputs
Select one of the Analog output tabs. The Analog output page looks like this:

http://www.innovatemotorsports.com/s...C-1_Manual.pdf (page 13)

This shows the analog output voltages versus Lambda for one of the two analog outputs. The
graph display is automatically scaled to the selected voltages. For each output you can specify a
minimum and maximum lambda value and the associated voltages. Below the minimum and
above the maximum lambda values the output voltages stay constant at the associated
programmed voltage.
By selecting the ‘use Air-Fuel-Ratio’ button you can program the curve by AFR instead of
Lambda. This does not change the programming, only the representation of the data.
When programming by AFR the LM Programmer converts the number to Lambda before
programming the LC-1.
Click the Program button to download the new data into the LC-1.
As factory programmed the first output simulates a typical narrow band oxygen sensor. The
second output is programmed to output between 0 V for an AFR of 7.35 (gasoline) and 5.0V for
an AFR of 22.39. Other curves of course are easily programmable

 

You have to use the serial out of the XD-1 to program the system to output a signal properly to the EU. The wires come of the LC-1 Module that should be connected to the EU. Brown should be connected to EU input. Green should be connected to EU ground or EU sensor ground input.

Hope that helps!

 

hey dave...thx for the imput...i have done everything that you have mentioned...
question:
why when i change a value..and then hit the program button... then when i go back into it again and then check it...the values are set how thye were before...meaning, say i change the lambda to a/f (btw, should i change it, or just leave it as lambda? does it matter?), i'll close the lm programmer, open it again (while evrything is still connected how it was)..and the changes i made are not there, the previous settings are there!!!??? What is going on?

and my xd-1 was displaying A/F perfectly before, now i can't get it to work, it jups between "O2" and 20, and 7...that's it, no 14.7 at idle like it did before
can u help me there?

so, what numbers do i use as a scale in the EU?
what numbers need to be in the lm-1 to ensure proper readings?
could u elaborate on these specific questions?

thanks
