I know this has been covered in previous old threads, and many of them reference a "how to" write up on VMP's site, however the link doesn't work anymore and I cannot find the info! Can someone please tell me how to properly connect my LC-1 wideband to datalog on my laptop via livelink and my X3? So far I have all the connections made, and slowed down the data rate on the LC-1, but kind of stuck after that. I found the analog input formulas section in livelink, but cannot find the LC-1 formula (there's an LCI, is that it?) and cannot figure out how to get livelink to display and record the signal info. I have the LC-1 formula from an old thread, and can input it manually if needed. Any help is greatly appreciated as my new SC will finally arrive Friday and I need to get this data to Lito!

Okay thanks, but how do I get livelink to recognize the incoming data and report it? I can't figure out how to turn on analog 2 in the software.

I will provide the formula as I want to work in lambda, don't worry for that.

I will send the config file with the analog you need but need to clear something first.

You use analog 2 in the LC-1 side, correct? Did you used also analog 2 in the firewire (SCT side?) (just to be sure we are in the same page here)

Okay sounds good. The LC-1 just has the two lines, one "IN" and one "OUT" so I used the "OUT". Currently, there is no analog 2 on the SCT side, I'm using my x3 as a pass through device to connect the OBDII to my laptop, then the LC-1 wire directly to my laptop also via serial connector. That's my issue I think is how to get livelink to "find" and signal coming in from the LC-1.

Livelink will never "find" that, has not been designed that way, it will only look at the 0-5V analog lines on the firewire port on the top of the X3, it uses a firewire cable for that, SCT sells one but generic ones do work too, this cable go to the analog 2 out you have on the wiring of the LC-1 and a common ground point.

Okay got it, I'll take a closer look at that when I get home tonight, thanks.

My firewire is spliced into the same wire that outputs to the gauge. LC1 is the analog equation for a/f of 14.64 = 1 lambda.

Well yes, that would be the issue. I assumed you at least had it wired up properly. Good luck on getting it hooked up.

lol since I didn't want to make a new thread about logging and wideband issues. I ran 4 datalogs last night and honestly didn't check to make sure the wideband was getting input and recording. I saw numbers so I was happy. Sent them to Lito and said they didn't record. I know for a fact it's all hooked up right, I believe it's in my formula. I put it in by right clicking "Analog 1" and then going to configuration.... later on going through some old threads I saw where most have gone to command and then analog equations from the drop down menu.... any input?!

swflastang05 sorry for the hijack lol

Lito gave me the formula to use for my AEM gauge. The gauge works on the display and all, but I thought it showed numbers in livelink while logging, but it was just ".683" the whole way across which Lito told me it was a value of 0 meaning that there wasn't a voltage pick up. So somewhere between the handheld, interface cable and livelink.

I just recently set up my SCT handheld device to a Laptop to datalog thru Livelink II. I connected a Firewire cable purchased from RadioShack to my Aeroforce Interceptor gauges which I also have the Aeroforce wide band sensor and the 2 bar map sensor hooked up to. First I cut the end of the firewire and checked each prong for continuity and verified my cable is setup the same as the one SCT sells. Then I found each 5volt signal wire going from my sending units to the gauges. I tapped into each of those and wired the wide band as Analog 1 and the 2 bar map as Analog 2. There was no need to hookup any grounds from the firewire and this is all the wiring that was needed. Then I connected the Firewire to my handheld which is connected to the OBDII input and to the laptop. In Livewire II you can select your analog inputs and insert an equation. I tried the equation livelink gives you for the 2 bar map and it is completely wrong. I called SCT and the tech confirmed it was wrong. He took the numbers that Aeroforce gives which are 2 for slope and 10 for intercept for the wide band, that equation for livelink is (v*2)+10 and then 5.8 for slope and –13.2 for intercept for the 2 bar map which equates to (v*5.8)-13.2 So I go to log and it doesn't work. I contact SCT and Jon Lund hoping someone can help. They both confirmed those equations are correct. Next I was able to find online the voltage readings that convert to the boost readings on the map sensor which is the one that logged way off. Then in livelink I took out the equations and left v for volts and it would log the voltage. Still the voltage was off. So then I pulled out my gauge and probed the signal wire to my map sensor with a voltmeter. It is the same signal wire I tapped into for the signal to the Firewire cable. Guess what it read the same voltage that livelink was reading on the other end of the wire. But the gauge reads correct. Now I'm really p#ssed and I yank the gauge out of my a pillar and guess what. Livelink now reads the correct voltage. So I plug the gauge back in and it goes off again. So with the signal wires connected to both at the same time it messed up the readings. My fix was making plugs so that when I want to datalog I disconnect the signal from the gauges and plug into the Firewire. This took me 3 days to figure out. But at least in the end I got it all right and have been logging for Lund everyday with great results. Now the next step is adjusting the equations just like you adjust the gauges for the correct readings based on altitude. This is outlined in the Aeroforce instructions. You just adjust the equations to perfect them to your altitude.

so out of all that, you're saying that I can't have both my gauge working and the interface cable hooked up at the same thing, it's either one or the other?

We'll see the AEM has an output 5v white wire made just for logging. I don't have to splice any wires or share the same wire for anything. That's what's confusing me.
