Chariot Gauge - Wideband O2, Boost/Vac, Oil pressure, Temp and Voltmeter

[codrum]

The overall look of the plot is kind of crap right now BUT! it's taking the data that I feed it and plotting it correctly so whew. Big hurdle maneuvered. More to come...

I've been making good progress on the iOS charting. I have the chart-area built and user interaction mostly complete. Next is handling how the "plot objects" are built so they can be configured on the fly depending on which gauge's data is being fed into the chart. Plus the number and type of sensors will be expanding in the future so it should take as little code as possible to build new plots.

It doesn't look like a lot yet but there's a lot of code behind functionality that will let it work with the data being fed into it.

Thank you! You should have an email with the tracking number.

Hi Jeremy - Shouldn't be an issue using the 14point7 wideband controller as long as it outputs a linear analog signal (for instance 0v - 5v for some AFR range). The voltage range and AFR range are adjustable in the app so any view will work as long as it's linear. Typically a broad range is setup from the factory that would show a good portion of lean, stoich, and rich areas (7 AFR up to 20 AFR) but most controllers can "zoom in" to a more granular view. As long as you set the app to reflect what the controller is outputting you're good to go. Lambda can be displayed instead of AFR as well if you would like.

All updates to iOS have been free and will continue to be! I recently released the plotting/datalogging update for Android - the same update is coming to iOS shortly.

Let me know if you have any other questions.

Very cool. Thanks again.

I've been eyeing widebands for awhile and was getting ready to pull the trigger when I found your gizmo. Looks great for my setup and I'm quite psyched to pick it up. So, just a couple questions.

I'm considering picking up the 14point7 Spartan Lambda controller/o2 sensor to use with the Chariot controller and my iphone 5. Any experience with your gauge controller and the 14point7 being used together? Also, I assume any future datalogging updates will be downloadable to ios for free, correct?

Thanks for your time and keep up the good work!

Bump. Still working on the charting for iOS - it's coming along pretty good so far. Back in the R/D department we're working on RPM input. Being able to plot RPM against boost/wideband would be pretty huge. More to come..

[codrum]

Bump.

I need to check the sensors, but I'm hoping I can install this on my '05 X3! I'm selling my current e30 but want this for both the X3 and my next e30 project.

Awesome work!!

Hell yeah! I would love to see a controller installed on an X3. Plenty in-stock ready to go when you are!

Still working on the charting/datalogging for iOS. I've settled on the CorePlot library which happens to be Apple's own for plotting data. It should be able to handle the quick updates in the same way the Android counterpart does.

In other news I finally got around to building a facebook page, I'll probably keep more of the updates there to hopefully reach a broader audience: https://www.facebook.com/pages/Chari...7041831?ref=hl

Happy fourth!

This may already have been covered but I need to ask it. I just got around to installing my Chariot Gauge system after months of it just sitting around.
Is it possible for me to use the OEM oil temp sender located under the m20 oil filter as the temp sender for the gauge? Can I change somrthing in the setting menu to make it work? Right now it just randomly spikes every few seconds and then goes back to 0.

Thanks

Hey man I think we got it covered in PM, let me know if you need any other help!

Rolled out an update to iOS that added BAR to boost and oil pressure. Had quite a few requests for it from the international users and I didn't want to wait to push out the update until the charting was complete on iOS. Android also was updated to handle BAR - that came with the charting update recently.

I'm not sure how I missed BAR on the pressure gauges initially - any other measurements I should add?
