Hello, time for a wideband and I hope to log without a laptop. As such I'm leaning towards the LC-1. Am I correct that it is the only one that hooks up to the tractrix?

Also I see that amazon offers the LC1 in a few different packages, I'm leaning towards a simple package of the LC1, o2 sensor, and a gauge. At their price the gauge is basically free. Would I need anything else to connect it to the tractrix?

Can I log to the tractrix and a laptop if I choose to do so later?

Can't find much info online or I suck at searching.....

Thank you in advance.

 

I've been looking into this myself, but it seems that it no one can get this to work. Everyone I know still uses the serial cable or the "pin 8" mod.

You might want to look up the zeitronics or AEM they might be able to do this.

Anyhow I'm just going to do the serial cable with my LC-1

 

I sent emails to both Innovate and AEM. Somehow I don't think either will reply, but I hope I'm wrong.

 

I was really hoping to do this, I much prefer stand alone logging. If you get an answer from either of those companies please share!

 

Got a reply from AEM.

Hello,

The 30-4100 UEGO gauge has a serial datastream output. This can interface with Evoscan software, and most likely the OP2.0 cable standalone logging as long as it’s able to receive serial stream data.

So now to find out if the port on the tactrix is "Able to receive serial stream data"

 

Ok found the following image for the AEM



For the LC-1 I found an old thread stating all you had to do was....

1. Make sure that "paramname = inno.afr" is not commented at the bottom of the logcfg

2. Plug in your 3/32" cable into the jack of the Open Port adapter and connect the other end to your wideband connector.

3. If everything is calibrated properly, you should have AFRs logged!

Rokpapaziz, I assume you've seen that and tried it?

 

No I haven't tried that, but I will this weekend. Can you post that other thread where you found that please?

I'll have a good look at the LC-1 manual. Do you have one of those? I haven't read the whole thing, just basically the wiring diagram for the calibration switch etc.

 

I don't know if I'm allowed to post another forum's link. I'll PM you.

The LC-1 manual is available online as a PDF. Here is that link....

I haven't dug much these last couple of days, works been too busy...

 

Thanks so much for that thread. Answered a lot of questions I had about this. Mine LC-1 kit didn't come with the 2.5mm to 2.5mm cable so I'll have to get one.

 

Very Cool! I'll keep my fingers crossed for you that it's as easy as it's made to sound. Let me know if it works, if it does I'll probably go with the LC-1!

It's interesting that it states in that thread that if you log directly to the tactrix that it gives you "smoother" data. I would think a laptop would log more smoothly as as I would guess it more powerful processor wise than the tactrix.

 

Yeah, I've noticed that I get slightly different feeling data... digital vs. analogue.

While the analogue has +/- 0.01V "jitter" evident, it seems to be a little more consistent after smoothing, broadly speaking.


I know the LC-1 analogue output can be set to "averaged" mode, ie. taking INTERNAL 300 samples per second and cooking it so that it outputs averaged results 12 times per second (which is why my standalone logging is set up for 12-13 lines per second).

Perhaps the LC-1 digital serial link reports "instantaneous" mixture readings. There doesn't seem to be an option in LM-Programmer for changing any digital-output averaging, you see...


But, in the end, you can definitely tune using both data sources.

This is why I'm just going with Zeitronix ZT-2 + ZR2 AFR and Boost in 1 gauge with datalogging

 

Hey Accursed I finally got my wideband and gauge installed. Haven't tried the Tactrix standalone yet, but I'm calibrated and hopefully can suss this out over the week. Still need to get a 2.5mm to 2.5mm cable

Sorry for the long delay. Will keep you posted

 

Thanks Rok, I put all that stuff on the back burner for now. Maybe after your success story I'll be motivated to make the jump myself. Good luck, bud!

 

OK I finally got this working. Took me ages to sort out logging with just the serial cable.

But now that's sorted I took a look into the stand alone logging with the Innovate LC-1 wideband and the 2.5mm stereo cable.

After getting some help from a couple of very good tuners I got some addresses sorted out and added this to my logcfg file:

Anyhow, it works. I haven't setup my stand alone logs to read in EVOSCAN, mainly because I just wanted to know that I can log AFR data.

Attached is a PDF of my drive to work this morning. You'll see the column "mylc1.afr" which is the headphone port on the tactrix reading the signal from the LC-1. Notice that the wideband doesn't give any data until the sensor warms up on page 4 of the PDF.
