Chariot Gauge - Wideband O2, Boost/Vac, Oil Pressure, Temp and Voltmeter: $49
Use coupon code november to receive $10 off your order through the end of the month! That's $39 for everything listed below.
A while back I posted a project I was working on and received great feedback from you guys - Chariot Gauge: a small controller that connects to five sensors: Wideband O2, Boost, Oil pressure, Oil/Air/Coolant Temp and Voltage. The controller transmits the data to a phone or tablet via Bluetooth and displays an analog and digital gauge or datalogging/charting. The controller is complete, and the app is available on Android devices, iPhones, and iPads. I've had a lot of success in various automotive communities, and I'm very excited to be sponsoring Honda-Tech now!
What you need:
1. An Android or Apple phone or tablet. Install the free app:
2. A controller/pigtail: Available from my site for $49: www.chariotgauge.com
How it works:
The controller comes with a Motorola MPX4250AP 2.5 bar MAP sensor (this is the same sensor that comes with MegaSquirt) on board that only needs a vacuum source - it is preconfigured in the app. The other four sensors are connected directly to the controller via the pigtail and are configurable for just about any intended sensor type. The install guide shows which wire connects to which sensor (found Here). When the controller is turned on you simply tap “Connect” in the app and select the controller.
Here’s a rundown for installing the other four sensors and configuring them in the app - Wideband O2: preconfigured for gasoline wideband O2 with an AFR range of 7.22 - 22.39 (works great with Innovate's LC-1/LC-2) but can be configured for many other fuel types and toggled for lambda or AFR. Oil pressure: preconfigured for an oil pressure sender showing 0-80psi but can be configured for almost any sender/sensor. Temperature: preconfigured for an open or closed element thermistor-type sensor. The volt meter can be connected to any voltage between 0v and 25v.
Various Android and iOS Screenshots

Here’s a crappy video of it in action (I’m working on a better version) :
What you get for $49:
Out of the box you get a 2.5bar (~21psi) boost/vacuum gauge ready to go. Connect the controller to a switched 12v source and a vacuum source and you’re set. You can stop here or connect the other four sensors as needed once you start expanding.

For anyone who would like a look under the hood both apps are open source:
GitHub Repos
If you like to hack around code feel free to fork either and send a pull request if you have some neat ideas or updates. If there's any interest in the board layout/schematic I can post up the CAD drawings of that too!

So if I'm reading this correctly, will this device decode the wideband O2 sensor output or do I still need a wideband controller? also will it work with the LSU 4.9 sensor?

The good news is that almost any wideband can be used. The app is pre-set for 0v = 7.35AFR and 5v = 22.39AFR which is what Innovate's LC-1/LC-2 wideband outputs come programmed as. However this can be configured for any values to match what the wideband controller is set to. If you were to program the controller to give a more granular view of 0v = 10.0 AFR and 5v = 15.0 AFR you can set the app to match these values and display the data correctly.
The Bosch LSU 4.9 would work great with any controller that outputs an analog signal!

The latest version of the Android app is available (ver. 1.5.2). A lot of small updates and bug fixes to handle data retrieval better and fix a bug that popped up from time to time when parsing data from the controller.
Might take a few hours to propagate on the Google Play store.

It is! The actual enclosure that comes with the controller is almost identical to an Altoids tin but more generic. I don't think the Wrigley Company would be too interested in sponsoring it but the controller was originally designed to fit inside the Altoids tin.
