Good to see it arrived in 1 piece.
Also good to see that LHD cars don't have the ashtray mirrored :-)
Does the lid still close?

I'm about to send another 4 out right now.

Mark, how about the additional 5.0 functions?

P.s. I updated the site today, and is final I guess.

Same here! Fantastic job - Bob has exceeded our expectations!

Yep lid still closes just fine.

Barnsie and I both have RHD cars, so unsure of your 'mirroring on LHD' comment.

I sent you a private message on here Bob

I've removed the infantile exchange of posts about a UK carrier.

Thanks GGG

15 amp is more than needed. The device itself also has an internal (self-resetting) "polyfuse" (PTC) of 500mA. The device uses ~260mA at full brightness of the screen @ 5V.

Yes, a typo of me, I meant RHD.

Bob can you explain the differences between Air Intake and AIT2 please?

Boost reading is working fine now but I only took it up to 90...allegedly officer :)

Barnsie you going to be doing some late night driving?

IAT2 I'm not sure, but I can imagine it is the temperature after the inter-cooler.
Could you check some time what the boost psi reading is at idle?

I assume one can configure the display to show volts/coolant together as shown in this previous diagram displaying coolant/speed.

I don't think so as have cycled through them all, so will assume this pic is an earlier prototype. Do you don't want yours now due to this? :D

It is a lovely piece of kit as Barnsie will soon attest to.

I’m hella mad (at myself) that I missed this glorious thread. Amazing engineering work by CambrioBob creating a really need product that benefits the community.

IF there is another round of product development (or an ongoing commercial effort), I’d gladly buy one. The products I’ve purchased from Forum members over the years have made owning the Jaguars that much better.

Bob - just to let you know my unit arrived safely. Looks superb! Not able to fit it today as I have been out most of the day, but will fit Sunday morning and report back. Really looking forward to seeing the unit in my car. Great work, and thank you so much!

No worries. I'm sure there will be some updates to the software and hardware to come. My suggestions are:

- If 2 gauges can not be shown on the current display have an option to alternate with 5 second intervals between 2 selected gauges. This should not be too difficult to implement with a bit of added code.
- Include a speaker to sound when a set temperature or metric is reached to alert the operator. This would require additional hardware and added code.
- Use a color display to turn red when a set temperature or metric is reached to alert the operator. This would be a display upgrade with added code.

​​Bob, has shipped a unit to me. I should have it in 5-7 days. I'm a retired software engineer and would be happy to add the code myself. I look forward to more iterations of this.

​​

That's possible in principle, but I choose not to do so since it will slow down the frequency of the OBD2 data request rate.
Yesterday MarkyUK found out that errors occurred on his device, caused by a too fast OBD2 data request rate. This had to be sped down from 300ms to 500ms in order to solve this.
Another problem what came out was that the differential temperature readout doesn't work, so that has been removed from the code.

Everyone who has had a shipping confirmation already will have to update their device when it arrives
with the latest firmware available on my website (4.2 / 3.5 EZ-Updater or 5.0 EZ-Updater)

update procedure (Windows):
- windows 7 / 8 / 8.1 users, download and install these drivers : click
- windows 10 has drivers built-in
- find yourself a micro-USB cable, plug it into the device and computer (see pic below)
- run the downloaded EZ-updater and follow the on-screen instructions.

- If you own a MAC OS X, updating is also possible, but only from within the Arduino IDE software (and download the "Model code" ZIP file)
- extract the ZIP and open the file with extension .INO
- All is explained how to do in the "Manual: software" PDF file.

I've had several more requests like this. I'm not sure yet if a second round will follow.
In the meantime, if you are a bit handy, you are able to build one by yourself, everything you need is available on my website.

I was tracking your shipment yesterday and saw it was delivered.
Be sure to update the device before installing, see 2 posts back.

Tada .......

Amazing!! Looks totally OEM! I love it!

Hey Bob.... I already installed it before I saw this. Mine seems to be working OK without the update. What problem does the update attempt to fix? ***It maybe something which only affects the 5.0 models and not our 4.2s?

I'll pull it out and do the update later, if needed after your reply.

Very happy with this though. The one metric I like to keep my eye on above all else is coolant temperature and this unit solves that perfectly for me. Voltage is the other one which I find very useful - for me, all the others are a bonus.

*** Saw this now in your post. My unit is not throwing any errors at all, or at least not in the 1 minute I had it running earlier.

It surely is!

That would be a really cool idea! Better, for me, than showing two readouts at the same time as this would inevitably make each one smaller.

Totally agree it looks like it was meant to always be there.
Is it just me or is your display background slightly red?
MarkyUK's looks more black background to the display.
Hoping it is just a trick of the light

Either way is still looks great, well done to Bob

If you look at it from our (RHD) drivers position it looks black. But when you look at it from the passenger seat or indeed take a pic of it, it has the red tinge.

Perhaps sommat to do with the screen or a coating??

One just taken at 10.30am dead straight on from the passenger side

The screen is of the "transflective" type, meaning still visible in bright sunlight. That's probably causing the colour shift.

Barnsie, you probably could turn your USB charger 45° anti-clockwise and plug the USB into to back side one, that way the charger can sit deeper and there is less stress on the USB cable.

The update has less frequent data requests from the ELM327 (0.3 → 0.5s),
removed the differential temperature option for the 5.0 models,
and has upgraded error "reporting" (on-screen) when an error occurs.
My 4.2 also has no problems with the "old" code.

There are endless possibilities.
Colour change when reaching a limit is easy,
switching screens with an interval is also possible,
a beep is also possible with a speaker (I have some laying around but didn't play with it yet)
The ESP32 is also capable of using WiFi, so it could even send you an email when certain conditions are met,
or update the device wireless using WiFi.

Gosh Bob you need to take a rest before considering upgrades!!! :)

All in the community (especially those 10/15 lucky enough to get one) are eternally grateful.

Next time I'm in NL the meal/drink is on me :D

It's just the photo. Must be something to do with the camera and the light. :)

Will do - thanks Bob.

Agreed!

Ditto. If you are ever in the UK, Bob, and anywhere near me, let me know!

Are there instructions for this Bob, if not could you write an idiots guide (as I AM that idiot)?

To use wifi (eg to send you and email if your battery voltage drops below xxxx) wouldn't the OBD unit have to be powered on permanently? And presumably so would Bob's unit, which isn't possible if the unit is powered from that cigarette lighter socket?

I got quite enthusiastic over the above idea until those thoughts occurred to me. ICBW of course.

Just been out for my first drive since installing the unit. Fabulous! You guys still waiting will not be disappointed. The display is clear and easy to read at a glance, regardless of whether it is in shade, the dark, or bright sunlight. Also very easy to use the button to cycle through the options. Mrs Barnsie was keen to see it and have a play with it and she was also amazed at the functionality and the OEM-look. This is high praise, believe me. :)

I think it ought to have a slick name. A boring suggestion is something like Additional Display Unit, or ADU for short. I think it needs something more interesting than that. Bobometer maybe ;) Or Bobomatic. Any suggestions?

Certainly deserves recognition. I like ADU.

Bob-a-Job maybe? (But Americans won't get this) :D

Regardless of the chosen it's a Fooking amazing bit of kit.

Please ignore my P.M I did not read all the posts.
If there is a second round in the next few weeks could you please add me to the list.
Its great when someone adds even more pleasure to driving our Jaguar cars.
Many thanks,
ArtyH

I am off out in a moment for a drive which will be a two-hour round trip. I am really looking forward to showing my buddy (who has a 2008 XK Coupe, which replaced his beautiful XK8 'Vert, red with cream leather) my new Auxiliary Display Unit (ADU).

I imagine that when he sees the ADU he will turn a good shade of green - he has always bemoaned the loss of 'proper' instruments like those he had in the XK8 - the coolant temperature and volts always being cited as the greatest loss.

:icon_banana:

I'm new to the ESP32, so no I don't know either....
