Best D4 Diagnostic Software,

[John_D4]

Forgive me if this has been covered many times, but as an iPhone person who’s just bought a 2013 D4, what’s the best monitoring/fault clearing product. For my D2 I use a nanocom, but it’s about $350-$400 to get the D4 licence and the cable.

I’ve been reading about these which come in the iPhone version:

IIDTool BT - Gap Diagnostic (https://www.gap-diagnostic.com/shop/iidtool-bt/)

Thoughts? (Just before someone asks, no I’m not interested in getting an android/Samsung/etc. I’m happy with Apple.

The other thing is, with the nanocom it sits in a mounted RAM mount and gets turned on when I start the car. I’m wondering if I’d be so diligent with a phone version?

[LRD414]

Yes it’s been covered many times, why not do a simple search in this section? The Gap iiD BT is very good and used by many D3/D4 owners, myself included, so there’s heaps of threads on it.

Regards,
Scott

There is an Electronic Diagnostic section on AULRO. Maybe look through there.

[Tombie]

You’ve nailed it John.... GAP IID for anything post TD5.

[John_D4]

It’s not quite as easy to search on tapatalk than on a desktop. I always think of these things when I’m on the couch!

[John_D4]

Great. Might sell the nanocom with the D2 then

[p38arover]

The problem with a GAP tool is that it's locked to the VIN. The Nanocom isn't.

Only certain functions.... it will do the essentials on other vehicles.

Wrong. Both are vin locked I know as I have both. The advantage of the GAP iid is it will clear faults on any Land Rover I have done this recently.
Also look at Blackbox's new ROVACOM-IQ. Smaller and cheaper than the GAP unit.

From what I can work out, the Rovacom is android only. Shame, it looks great.

[John_D4]

Nanocom isn’t locked. You can use it to check your friends car also. Otherwise I’d never be able to buy a 2nd hand one

[Tombie]

The additional benefit of GAP is custom firmware updates can be requested for certain things!

Unsure if Rovacom are offering this service.

If you mean updating vehicle component software, then yes. The Rovacom/Nanocom Genesis site lists all the software for a particular module and highlights which version was installed on your car. You can then download and install later versions. I've never been game to do this as all is running fine as is in my D4.
As for updating the Rovacom software and the IQ dongle itself, then yes, it automatically advises if there's an update as soon as you open the app. It takes seconds to download and update and then update the IQ dongle.

[Eric SDV6SE]

+1 On the Rovacom for me

[p38arover]

Rovacom is locked, Nanocom isn't. I had both.

[John_D4]

Rovacom is still Android - I’m an apple freak

Good insight for others reading but Not what I was referring to.

GAP will write custom firmware for certain functions if requested / possible.

I have the full professional Rovacom gear as well as 2 GAP tools, and the GAP gear is my go-to for most stuff.


What I can completely recommend is installing Later D4 Terrain response software onto the earlier D4 systems. It makes it *that* much better.

[John_D4]

Wow the GAP Pro is expensive. What makes it $2200 better? Just curious, I’m not spending that much

No restrictions - unlimited licences - for workshop use.

The BT tool is for private use.

[John_D4]

[BMKal]

I have the BT version of the GAP IID tool installed on MacBook Pro, iPad Pro and iPhone X. Works without problems on all three.

[John_D4]

Can you leave the iid attached or do you only attach when using it?

[Tombie]

Can you leave the iid attached or do you only attach when using it?

Yes.

I’d recommend an extension cable to move it away from your right foot.

And

You must disconnect the app before shutting down the car.

[BradC]

You must disconnect the app before shutting down the car.

Just to qualify that, you don't actually have to. Quite often if I'm just stopping for fuel or ducking into a shop I won't bother. Just chuck the tablet/phone in the glove box (which I do anyway) and it's all up and running when I get back.

Yes, it stops the car shutting down fully but it doesn't cause any issues aside from increased battery drain.

Also, there is no apparent issue disconnecting after you are out and the car is locked. You probably should deliberately disconnect, but many times I've walked away and forgotten to disconnect and the connection seems to time out. Leave the tablet in the glove box with it connected though and the car will go flat before the tablet does :)

[John_D4]

Sounds like the nanocom in my D2 is a better idea! I leave it permanently attached and set to start in instrument mode. Super easy & idiot proof

The Rovacom IQ (also by BBS) is designed to do just this. The IQ is a small terminal that plugs permanently into the OBDII port and you communicate with it via bluetooth on an Android device. The IQ is ignition powered so switches off with the ignition.

Is there a way to check in the app what the current version is, and what should it be if it's the latest?

[Tombie]

ECU info screen.

Read the manual, it is very comprehensive for each task.

OK so I've previously done the digital dash update which fixed a glitch with cruise control display. Nothing else showed up as having any available updates so if that's the process then I guess I already have the current version.

Thanks.

[Tombie]

In the app there is a section to interrogate the ECUs.
It will generate a report of all ECUs in the vehicle and advise if there are updates.

Note - each update is around $25.00

[LRD414]

Terry, I would expect there’s an update for your TR given it’s a 2010 model.

Hey Scott / Tombie,
In regards to the terrain response updates, I just had a look on genesis and there is an updated file for me, but seeing as Tombie says he has a custom file made, do you think it would be a minor update / glitz fix? Or a major update?
Any noticeable tests I can do?
I did a terrain response course with Gordon and he did mention that there was a newer generation that succeeded my MY11. Not sure that LR would release an update to bring us old owners up to speed with the new models.
Hell they won't even update my sat nav,, my house is five years old and doesn't exist!
Are the file names and types the same between the two units? Can I pay gap to build me a file and upload through my rovacom iq?

[John_D4]

I’ve just emailed bbs to see how long before an iOS version of Rovacom is available

[rocket rod]

I have few updates available but how do I know what's in them to see if it's worthwhile updating? I've done a search on a few but can not find anything. Just curious.

[TB]

OK, wow, there are a lot of updates showing for my vehicle. 153190

As others have asked... how on earth do you figure out which ones are actually worth paying for? I could spend a small fortune and have no idea what the outcome might be.

[LRD414]

... how on earth do you figure out which ones are actually worth paying for? ....
Really only via feedback from forums. Gap can provide the update but not the potential benefits.

Scott

[LRD414]

Can I pay gap to build me a file and upload through my rovacom iq?
I can't say it's impossible in theoretical terms but I'd say the chances are probably the same as being kicked to death by a duck.

Josh,

The updated files upload to the vehicle just fine.
It will give you the later performing Terrain Response.

Well worth it, it’s so much better again!

[John_D4]

Here’s the answer I just received now:

Dear John,

Thanks for your E-Mail.

As you might appreciate, our Rovacom-IQ app and matching VCIQ hardware has
only recently been announced and released.

We have developed the app using a cross compiler, so we clearly intend to
add an IOS version at some point.

However we really cannot commit to any time frame for that and if we had
to take a guess, it would be a minimum of 6 months from now.

Any news will be announced on our website.

Kind regards
Andreas

OK, worth a shot. Ordered! Thanks for the advice, I'll let you know if it blows up :D

Make sure to have a power supply based charger attached to your battery when doing updates.

The vehicle needs stable power for successful programming.

If you don’t have a charger with supply mode, at minimum fully charge the battery before attempting updates.

Hmm. I have a 6A 9-stage charger. OzCharge 1206U. I'll take the Disco for a good drive then connect the charger before initiating the update. Thanks again.

My power is a little remote .... I'm wondering for the price of an OzCharge 1206U - I should just go for a dual battery traxide kit... (Haven't worked out it it gives the resilience)

These updates are they the same sort one would get during a service at a dealer, or in effect modifications?

[Tombie]

Unlikely the dealer will kid the latest Terrain response to an older vehicle.

Also, dealers only do ECU upgrades if the client complains of a a problem that these updates are known to resolve. (Ain’t broke don’t fix mentality)

[John_D4]

Wondering, is the incorrect lt/100km thing fixed when you do a remap?

[gofish]

Just curious. If you've had a re-map done are the terrain responses updated as well (generally)? I'm guessing not but thought I'd ask.

[loanrangie]

Wondering, is the incorrect lt/100km thing fixed when you do a remap?It's not incorrect as such but an estimation given mileage, speed , fuel useage etc.

[LRD414]

Fuel consumption involves a CCF setting, so unrelated to an engine ECU remap or any other ECU. Similarly the terrain response program is in a different ECU to the engine one that can be remapped.

[John_D4]

Not trying to hijack this thread, but is it possible to change the lt/100km settings to make it true? Just a yes or no answer is fine, if it is I can start a new thread to discuss properly

Yes. Takes time and a bit of guesswork.

The overall reading is averaged over a set time period so will vary from real on occasion.

It took me about 6 tanks to get it accurate.

In my case yes. I rarely use the BBS gear I have anymore

I think the transmission is pro'ly worth doing as I recently had mine changed, and ZF must have loaded the latest programme, as it feels sportier and also seems to be able to retard the speed much better when using Cruise Control, I suspect it might even be shifting down, as the old one would run away down hills.
