wideband and efi live

[ZL1Killa]

I don't understand a dern thing up here about the lm-1 and efi live.

one guy says and shows the 3 wire pin that connects into the black efi live box and the other says with the lc-1 and an analog voltage.

How exactly do i go about getting efi live to read the lm-1 using the lm-1's analog output into efi live's black box on the cable???

I hooked it up with the 3-pin (3 wire) piece and it doesn't seem to work

When my wideband (the lm-1) was reading idle a long time back it was reading 14.7:1 and around that.......now I'm reading 20:1 and above...all the way up to 35!!!! WTF

[ZL1Killa]

alright...well got it to go to 14.7:1 and idk what else i'm going to do

I have the lm-1 and I'm trying to figure out exactly how to wire it into efi live....these online guides from what i'm reading are the lc-1 and all i have seen from what ppl have shown me is that for the lm-1 you use the analog output on the lm-1 and plug 3 wires into the 3 wire thing that sticks out of efi lives black box.....

i know there is more than that tho

The wideband O2 inputs on FlashScan are actually a voltmenter that takes an input voltage between 0 and 5V and converts that to an AFR between (usually) 10 and 20 AFR.

You only need to connect two wires from the LM-1 to FlashScan. On page 21 of the LM-1 manual in section A3 is a diagram of a stereo plug showing three contacts:
1. Analog 1
2. Analog 2
3 Ground

From that connector, you need to connect:
LM-1 Analog 2 to FlashScan pin E
LM-1 Ground to FlashScan pin D

Then log at least the following PIDs in EFILive:
{GM.AFR}
{EXT.AD1}
{CALC.AFR_LM11}
{CALC.BEN_LM11}

Using LM-1's PC based configuration software, you should check that the Analog 2 output is set to the following values (since that is what EFILive expects for an LM-1):
10 AFR = 1.0V
30 AFR = 3.0V

thanks man, I do appreciate the clarification so quickly. I will let you know how it goes.

[ZL1Killa]

ok so if i'm using the Anlg voltage 1 (red wire) and in E on the black box and the common ground (copper lookin wire, and in D) is all i need hooked up right? and then calibrate the lm-1 for the 1v=10AFR and 3V=30AFR using the lm-1 software??

what exactly goes in the 2 wire connector that plugs into the efi live black box?? is it simply those two wires in the 3 wire plug and calibrating the lm-1 unit to the above voltage :afr readings??
then plug it in the tailpipe and take measurements and I can then use the lm-1 and efi live to do the ben factor?

[Blacky]

By default the analog 1 wire from the LM-1 is set up to output a narrow band O2 voltage signal. That is not what you want to log with EFILive.

You want to log the wide band O2 voltage which, by default is analog 2 on the LM-1. So you need to hook up the analog 2 wire fromt he LM-1 to either E on FlashScan and the analog ground from LM-1 to D on FlashScan.

Try to fit the bung for the LM-1 wide band sensor as close to the collector as possible - reading from the open end of the tail pipe is not recommended.

yeh i know about the tailpipe readings being inacurate.....I will see about mounting it on the y-pipe in the bung. I have no cats and i thought that that reduces error from reading at the exhaust tip...but I can hook it up to the y-pipe and I will soon do so. I will do a write up on this and do it in word with pictures so that everyone else who gets online with an lm-1 can understand how to exactly hook it up. I also have to get this to dynotune.org (for Dean) as he sells the wideband units and he wanted me to look this up and either send him a link or a write up

[ZL1Killa]

ok....how in the world do you get the wideband setup to get the 1V=10AFR and 3V=30AFR???

when i started my car efi live with the wideband was connected the readings from the wideband that were shown in efi live was 36:1 afr basically and the reading on the actual lm-1 was 17:1

[ZL1Killa]

alright, well i got efi live and the wideband working BUT (as always)

the readings that efi live is seeing is : 19AFR to about 21AFR when the actual is 14.5 to 15 AFR


I have the white wire (on C) and the ground(common) in the center (D) and this is how i'm getting these readings. something else is wrong...just can't figure out what... I am running a usb to serial converter...maybe it has something to do with it but i doubt it. don't know what else to do

[SS2win]

still have the air pump hooked up? arf will be way high until it cuts off. otherwise do the free-air calibration.

[ZL1Killa]

naw...its off completely....

the thing is that the AFR reading on the lm-1 IS correct its 14.6~15


but only when i try and read from the stereo jack and plug the 2 wire (3 wire orange piece) into the efi live black box does it read 18-19AFR?? i mean honestly...wtf

even the lm-1 program reads what the unit is...but i guess thats straight from the reading on the unit itself. I will post some pics up later...i just don't see why its so different...i read the tutorials and looked at what other people have done and according to that mine should work...but u know how that goes

[SS2win]

I dunno man. My LC-1 went in real easy. I use the stereo plug to connect to the laptop serial port and the analog out #2 to connect to flashscan. That way I can see what innovate's logworks says in comparison to what EfILive logs. never tried to hookup flashscan via the stereo jack

[ZL1Killa]

never could get the readings quite right on the lm-1 setting in efi live...had to set the wideband in efi live as plx and it worked fine...running from 1v @ 10AFR and 4V @ 20AFr and it works perfect..weird but nonetheless it works

[Blacky]

The LM-1 unit should have come with a CD that has some software that allows you to connect to the LM-1 controller and set two voltage points and two matching AFR values.
EFILive expects the LM-1 to be configured as:
1V=10AFR
2V=30AFR
3V=30AFR
4V=40AFR
5V=50AFR
Set any two of those in the LM-1 software.

If the LM-1 is set up differently to that then you have three options:

1. Change the settings in EFILive to match the settings in the LM-1. You would need to change the expression for the LM-1 configuration in the file:
\Program Files\EFILive\V7\Configuration\sae_generic.txt

or

2. Change the LM-1 to be configured as above by using the LM-1 supplied configuration program.

or

3. Use one of EFILive's other preconfigured wide band PIDs that match the LM-1. But you must be absolutely certain that the "other" PID you choose is configured (in sae_generic.txt) exactly the right way for the current LM-1 configuration.
Or you may get values that look right, but they might be wrong by 5%, 10% or more.

2V=30AFR
3V=30AFR
4V=40AFR
5V=50AFR


I personally don't like that setup, you are only talking a very small 'useable' range, like 1V - 1.5V, that is BAD.
You would be better off creating a calc PID and scale the output similar to this (if possible) -
0V = 10AFR
1V = 12AFR
2V = 14AFR
3V = 16AFR
4V = 18AFR
5V = 20AFR

2V=20AFR right?


I KNOW WHAT I DID.....I followed the write up and was using 3V=20AFR......but I will CHECK this thursday about all that

I will try this and see how it goes thursday when I have plenty of time to play.

So i could set 1V=10AFR and 3V=30AFR and it SHOULD work right?

[ZL1Killa]

1V=10AFR
2V=20AFR
3V=30AFR
4V=40AFR
5V=50AFR

for one the limit on the lm-1 programmer for the lm-1 will not let you exceed 22.5AFR so 3,4,5 volts don't matter

only 1V and 2V will matter. I just hooked it up and it won't let me put 30AFR. but it will let me put the voltage.

I'm now going to try the 1v=10AFR and 2v=20AFR since thats what I will be staying in anyway

[Dirk Diggler]

0-5 volts will give you more resolution why not program it for that

0=10
5=20

AFR=v*2+10 is the formula and should allready be predefined in the software for one if the other Widebands

That is a very good point and probably something that you should do.

That means either:

1. Using the PLX PIDs for your LM-1 (the PLX PIDs in EFILive are set up for 0V=10AFR, 5V=20AFR)

or

2. Changing EFILive's sae_generic.txt file from this:

# Innovate LM-1 WBO2
# ========================
*CLC-00-922
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 30.0 .1 "{EXT.AD1}*10"
*CLC-00-923
factor 0.0 2.0 .1 "{CALC.AFR_LM11.AFR}/{GM.AFR}
*CLC-00-924
V 0.0 5.0 .1 "{EXT.AD2}"
AFR 10.0 30.0 .1 "{EXT.AD2}*10"
*CLC-00-925
factor 0.0 2.0 .1 "{CALC.AFR_LM12.AFR}/{GM.AFR}

to this:

# Innovate LM-1 WBO2
# ========================
*CLC-00-922
V 0.0 5.0 .1 "{EXT.AD1}"
AFR 10.0 20.0 .1 "{EXT.AD1}*2+10"

ok i will try setting the 5V=20AFR 0V=10AFR and I will let you know how it goes.

i think that will work, thanks for all the help guys. Didn't think it was going to go well for a while there.

[ZL1Killa]

also...once i get my VE dialed in...what tables do I change to change my air to fuel what i want it to be for the different rpms? the pe table, b3618?

[Black LS1 T/A]

How did you do on this issue?

[ZL1Killa]

everything is resolved...

dag this had been a long time. I have everything working fine now, and I even dialed in my MAF table
