Sorry it was a Generic question about mapping tools I was going to ask.
Seems you can get some for around 600 quid.
But specifically we had a wounded Navara D40 2.5 that we believe either has a faulty DPF or sensors in the DPF.
Snapon diagnostics have carried out a Regen but after the Navara has been driven for approc 1/4 mile the DPF light comes on again. So looking to map out the DPF to test....but its 250 quid a pop round here. So that's 500 to test and put it back to standard. My sons work just paid 250 to map out ad blue so he could recover the outlay if we got one..

Mapping can be really quite ECU specific - there are tools which cover a lot nowdays, but you still tend to get a lot of specialists that concentrate on a specific make or even a specific ECU.
By mapping I mean actually remapping each load site in the ECU for performance or economy. I suspect a lot of what is referred to as mapping is simply just turning on and off features in the ECU via diagnostics - which is a good deal different.

@premmington may suggest something
Can get petrol injectors tested but not diesel.
With mapping if can get a decent dealer package with backup then its a good crack.
Used to use "elite remaps" through a mate for all out vehicles and worked well with egr/dpf removal as well as mapping for eco/power.

As an aside, the ad blue delete was all the rage on lorries when ad blue first came about.
They have recently done something to the emissions test and it can tell if you’re burning it or not. The tester can tell by looking also. Now everyone has deleted the delete and the ad blue dosing pumps fail. Amongst other things. Not sure why. I’ve changed a few on trucks that have been put back to standard.
Just to be aware of for your boy that’s all.

Yes, a couple of years ago Vosa were on this roadside and its part of the test now. https://www.gov.uk/government/news/checks-for-lorry-emission-cheats-start-across-great-britain

That
My software is capable of coding, turning on and off features, though even that is not for the feint hearted, an ecu can be bricked even if that’s not done correctly, I’m not brave enough.
Mapping, the re-writing of fuel, boost and (ignition in the case of a petrol engine) curves and that’s on a different level, especially live re-mapping.
For what you’re looking for I think you’ll need to go to a specialist, I’d be very wary of a backstreet DIY job when it comes to fiddling with the code in an ECU
Edited to say just noticed your second post, and Snapon Diagnostics should have read the fault codes before carrying out a re-gen. All of the sensors should be checked with no fault codes found or else the re-gen won’t work.
Im not familiar with Nissan but on most cars there’s a whole list of things which will prevent a re-gen from taking place
I think most manufacturers early AdBlu systems had issues, as it was a new technology, but newer systems are a lot more reliable.
The big issue was AdBlu crystallising in the system, especially on trucks that were only doing local drops.
I've had many AdBlu pumps apart, and as long as they're still electrically working, a strip and clean with hot water to clear out any crystals usually solves most issues.

Yup. Agreed. I have stripped and cleaned a couple and you can get seal kits for most of them.
The guy who owns the fleet of trucks I replaced about 6 (I think?) on, wanted new ones. His money
I put the old ones on one side in his stores to recon when I had a minute but not there so much at the moment. I’m just doing his inspections. A cheaper guy does the spannering. I’ll be back when they work out me fixing **** was cheaper than the cheap guy replacing it!
Not sure if they test for adblue on the Navara MOT but I mentioned it as it may help the OP
Yes
Our problem is that since cleaning and refitting everything when you take the truck up the road the dpf light is off from the start, but the truck has no power. When the truck reaches a certain point (within feet) the dpf light comes on and there is even less power.
What we are trying to establish is whether the snapon was just turning off the light and not deleting the fault. Leading to the DPF fault coming back after the truck has travelled a certain distance or for a certain time.
I do have access to.nissan consult III so we will be trying that.
The snap on read the codes and turned the light off. It definately regenerated as there was lot of smoke and heat to start with.

My Navara does not have adblue it's an 07 Auto.Yup. Agreed. I have stripped and cleaned a couple and you can get seal kits for most of them.

What's the difference between testing then @Ruffian ?
My son has a photographic memory and picks things up quickly.
Som of these packages offer training and he's not about to drop a remap on his GTR his tuner will do that.
I fully appreciate the comments from members that you can do damage if you don't know what you are doing. That said everyone had to start somewhere or you will never learn.
It's quite funny as I am admin on a sublimation forum and I constantly see comment like " I want to start sublimation so can you tell me how to do it."
To be met by members replying "you need to do some research first" now I know a fair number of those replying knew nothing about subbing when they first joined the forum. Lol
Hence my researching various places and asking some silly questions.
Do you know what fault codes are returning?
The dpf code... my gut feeling is 1 or more of the DPF sensors are either dirty or duff.
I have spoken to Bill cars nissan.. the guy was a real gentleman and suggested that what he would do if it were his was buy a second hand DPF as that is what they would do as most people can't afford a new DPF.
Ideally it would be nice to find someone with replacement sensors we could fit and try but I am guessing that like finding rocking horse poo.

Could it be a problem further downstream in the exhaust like a collapsed baffles? Maybe try disconnecting exhaust briefly to see if power comes back?
