Neither. When I had the VEMS gauge, the sensor was a Bosch item. Not had the pleasure of Innovate gear. If there was a utility for the Empeg that displayed the output, I'd grab one. My C, like my grasp of all computer languages, is non-existent

Well, no response to the PM unsurprisingly. I'll try the admin email request route.

Hi Everyone,
Sorry to have kind of disappeared. As tends to happen with most of my projects, I got this software to the point where it was usable to me and since no one else seemed interested in it at the time, I didn't do much else to it. So, the code isn't really commented at all and probably has quite a few bugs in it.
I'll attach the code to this post. I'm not 100% sure that this is the latest code. It took me a while to find it...
Let me know if anyone has any questions about the code. I don't currently have it installed on my empeg since I had to replace the hard drives recently and the wideband isn't installed in my car at the moment. I'll probably reinstall it when the weather gets a little nicer around here. Sorry to have disappeared for so long, I'm not quite sure why I didn't get notifications of the posts on the subject.
I would love to know if people have success with the program!
-Jeremy

Hi again,
Just so you know, if you aren't used to compiling your own software, I didn't post a binary of the program, just the source. I have to get a cross compiling environment set up to build a binary. I'll try to do that later today and post a binary. Also, this requires the Hijack kernel to work. I had it set up so that I could launch it from the hijack menu. Also, I made a custom serial cable for the wideband that omitted one of the data lines so that the wideband didn't see the output from the kernel on boot.

Hi Jag!
Do you have some info regarding the cable you've made and how you wired it to your sensor?
Thanks!

The serial port on the innovate wideband that I have is a mini phono jack (or maybe even the smaller ones that they use for cell phone headsets, I don't remember). Normally, one wire would be data to the wideband, one would be from the wideband and the other would be ground. I just omitted the one that sends data to the wideband so that the garbage coming off the serial port of the empeg on boot wouldn't mess up the configuration of the sensor. I can find out exactly which wire is which when I have a chance to pull the cable out of the car. -Jeremy

Thanks, Jeremy. Meanwhile... I see some good info on the LC-1 product page at Innovate Motorsports.

Welcome back Jag Thanks for posting the code. I'm going to take a look through it as I have a LM-1 myself and I understand that the protocls are different in some way. I have access to a LC-1 but it's been a bit dodgy. Never the less, I'll see if I can't get it on to my empeg and doing a little testing myself.

I hope it works for you. I think the LM-1 protocol is pretty much the same. It data logs more than just Oxygen right? I have attached the PDF of the serial protocol that I used to right the code. I'm not sure how much I assumed about the data since I had an LC-1. I think I was trying to right it to be a little flexible but it was just a first stab at the code. Let me know if I can help.

I think this is actually the more recent code. I haven't touched any of this code in years but there is a compiled binary in this archive so that makes me think that it's the more recent stuff...

I am having trouble with the attachment, when I tried to unpack it I get the message "tar: This does not look like a tar archive". Is it me or is it the file?

Possibly both, compounded by your browser "helpfulness". Are you unpacking the tarball using the 'z' flag? If you are, then your browser probably already uncompressed it for you, without renaming the file correctly. If you aren't, then you probably should be.

It's the file. It's a compressed tarball (created with the 'z' flag), that was then passed through the gzip program a second time. So... gunzip it, and rename it to have a .tar.gz or .tgz extension, and tar will be happy to xvzf it.

So, now I just have to figure out how to stop the kernel from outputting on the serial port... Okay, so it only took me four years.. Hijack v509 is now released. The only significant change, is the addition of a new option for config.ini: This suppresses all (?) hijack messages at the serial port.

Thanks! I was wondering why some serial messages were still getting out despite having suppress_notify=1 set. Thanks!
