AJP Dash - free Android dashboard for TVR AJP engines

[dekoene]

Hi all,

Like many of you I used RS-AJP to read my MBE ECU, but it no longer works on recent Android phones. So I built a replacement: AJP Dash, a free app that talks to the ECU over the standard diagnostic lead.

What it does:

• Live dashboard: rev counter, GPS road speed, and a gear indicator that learns your gearbox by itself
• G-meter using the phone’s own sensors
• Three tiles you choose yourself (water, oil pressure, battery, lambda, injector duty cycle, …) with min/max
• Live and logged fault codes, with a counter showing how often a fault appeared (handy for intermittent sensors)
• Adaptive fuel maps for both banks as a heatmap, with the cell the engine is using right now
• Fault, service-interval, adaptive and throttle resets (with confirmation)
• CSV logging, oil-pressure warning (S6), built-in help, English and Dutch

What you need:

• Android 8 or newer
• A USB-OTG adapter, a USB-RS232 cable (FTDI, Prolific, CH340 or CP210x) and the usual TVR diagnostic lead. An RSiAJP BLE232 Bluetooth adapter also works.

Status
Tested on my 2003 T350C (Speed Six, MBE 941) and checked against logs from AJP Diagnostics and the MBE software. The V8 is recognised, but I have no V8 to test on. If you have a Cerbera or another AJP V8 and fancy trying it, I’d really appreciate a short log and a screenshot of the Status page.

It’s an APK, so allow installs from unknown sources. No ads, no account, no internet permission. APK is shared by @Byker28i (thx for the testing on a V8) on the Cerbera forum

Credit where it’s due: the protocol knowledge comes from RS-AJP, AJP Diagnostics (KCC Ltd), RSiAJP (Greg Scullard) and the MBE diagnostic manual. AJP Dash is an independent hobby project, not affiliated with any of them, with MBE or with TVR. Use at your own risk, and please don’t fiddle with it while driving.

Feedback welcome!
