Elgrand Android APP

Build 50 is on Play. Install it over the top as usual (never uninstall).

This one is about making the app easier to read, and about setting your van up properly if you want to.
  • Readable in daylight. Darker, larger text. Setup → Display now has Day, Night, Auto and "Day 07–19, Night after".
  • Calibrate your van. A new guided sequence in Setup for speed, odometer and fuel. It's optional, and the GPS speed check needs the app open. Please have a go, because it's how we get every van set up the same way.
  • Petrol "Filled up" box. Enter the pump litres and your dash odo after a fill, and the app tunes your fuel figures from a full tank. A calibration history shows what changed and when.
  • New starting fuel values. Offered once. If you've already tuned yours, they stay as they are.
  • No more guessing. With no fuel price set, the app says "set fuel prices" instead of showing a made-up cost. Economy shows in L/100 km if you use kilometres.
  • Logging you can see. While the app records, a "logging in progress" notification has a Stop logging button. Setup shows whether background logging is on and the time of the last reading.
  • Smaller fixes. Trips no longer lose short gaps in the link. The app warns before an older import replaces newer records. A phone gives up after about 20 seconds if the engine isn't running, instead of 3 minutes.
  • Privacy Policy link in Setup → About.
  • Android 12 and later now ask for approximate as well as precise location, which those versions require. It's only used for the GPS speed check.
Thanks to all the logs and emails - all your feedback is useful and builds into the app!
 
My mistake. I bought off AliExpress for £23 not eBay... Took about a week to be delivered but it is spot on. I just got the FD one at £23.71


2026 New Vgate vLinker FD + BT4.0 V2.2 Car Diagnostic scanner ELM327 for Ford Forscan OBD2 Auto Scanner J2534 PK V1.5 ELM 327

There are some on eBay for £23 but if you're ok with AliExpress at least you'll know it's genuine.
Hello, what program is needed to use this device?
 
A big thanks to all the testers - we have 15 registered testers at the moment & feedback by the DM of logs and reports from the app are what improve the app and iron out the bugs. Keep them rolling in.

I'm approaching 50 build updates on this now and could do with a last push to get some more logs in, I need to get a few more testers registered with Google and then I will release on Play Store for general Joe Public download and use. It'll not be perfect & I'll still update & improve with Forum feedback etc - remember it's a passion project & I'm not an app developer!

To be released on Play Store the app needs to be downloaded by at least 12 testers and maintained on their device for a continuous 14 days - if you uninstall any time in the 14 days we lose you in the count - that's why we could do with a few more testers and active users, with a good wind we can release on Play Store in a couple of weeks for public use.

The app will be FOC with no subscription required.

DM if you want to test & get this over the line with Google.

Thanks

If you are doing this app FOC then I might be interested in providing some resources for things like secure external persistent storage for the same price that you charge. My company has a data centre with quite a lot of stuff in it.

I am seriously impressed with your app. It is obviously vibed but it is also directed by someone who knows what they are on about. Please keep going and if you think I can help out, give me a shout.
