Any way to log using an android device?

[lsxautumn]

My laptop kicked the bucket and I really need to get some logs to dial in my VE table. Using a p59 pcm with the 7603 OS. Using the obdxpro gt. I have my desktop pc to make histograms make changes and do the flashing. Thought I'd ask if I can log data on android before I go spend money on an x86 laptop. Thought about LSdroid but the oldest android device I have is android 11 so that's not an option, not that I even know if that did logging.

I normally have an old elm on hand and use torque on my android to do basic debugging. I'd assume it can be used with the xpro gt as it supports elm protocol. But there are probably better apps out there designed for elm that someone could recommend. I dont have any need to do any tuneing at home so I am only ever doing basic checks of things on the bench.

I am hoping to get logging working on Android, but it's probably months away.

The first step is to get a unified flashing+logging app working on Windows, using a cross-platform UI framework, and I'm working on that now. Slowly, but I'm working on it.

The next step will be to make it work on Android. This will be my first Android project so it might take a while.

Tried torque to log and on paper it looked like it should work but for whatever reason it wont log a couple parameters I need. It absolutely refuses to do EGR voltage which is where my wideband is and it also refuses to log commanded AFR. It also for some reason doesn't even acknowledge IAC pids but tech2win does. I'm sure its some sort of user error on my end but I do wonder if torque is good with j1850vpw since it appears to be targeted more to can. The predefinited extra gm pids are basicalily non functional for me and I've tried every mode and messing with the header settings to no avail. I'm not really a tuner but I built a custom stroker motor for my DD truck and the stock ve table is way off for obvious reasons even when displacement is accounted for. Long term fuel trim though is at least giving me a starting to point to go and its improved from the changes.

You're welcome to look through this .csv export from Torque. I do have my wideband through the EGR working. Some of the custom stuff in it is just me playing around. Hope it can be of some use to you.

I'm using a P01.

Best I've found is using RaceChrono, based on the effort from @jlvaldez. Simply because it's very customizable and you're able to build out and utilize 2C/2A logging, which helps boost the limited speed you can get elm327. Also torque sends a lot of extra commands (been ages since I sniffed the bus I don't remember details) which further slows it down.

In this example a total of 12 bytes or 9 PIDs are logged in location FE and FD, and RaceChrono is smart enough to send a single request and parse out all data from the response (if set up correctly of course). It is cumbersome to set up as it's an universal app, but once set up works well.

I forget exact logging speed details, but it was much faster than regular mode 22 single request/response. Can post more or help more next week when I'm back home, if needed.

I am getting a log now with actual numbers in it for the EGR now although the scaling is completely wrong. But the fact I'm getting anything is an improvement. I tried setting it just to [22114b] with 0 and 5 as the min/masx but the logs just give me values as high as over 35 when the wideband is warming up but it'll still be as high as 20 when used.. Do you know how to convert that to the 0-5v? Was planning to just log the voltage and use excel to convert it to lamda.

What is your EGR voltage PID equation to set to? That is the PID represented in line 25 in the .csv file I attached above.
