Re mapping

[Paul and Val]

None of our re-mapped cars have ever been picked up by dealers. The only possible issue in the case or a re-mapped vehicle (as against one of the cheaper and less efficient 'bolt on' tuning boxes) is the slight possibility of the map being overwritten in the case of a major reprogramming by the dealer.

One of the re-mapping companies could give more information on this. It has never been a problem for us.

In my experience there is zero chance of the dealer finding the re-map (and I doubt very much they would be bothered anyway, it is a very common thing these days).

I have never met anybody who has had a re-map done who has regretted it or had any vehicle or warranty problems. There does seem to be lots of very nervous, worried people out there. If you tuck your shirts into your underpants for added security you probably should not have your vehicle re-mapped. Think of the terror!

That’s why I have a removable box , it would be removed if warranty work was needed , they can’t tell it’s ever been on

I must admit that I've never been a lover of the removable box-thing as all it does is intercept a single feed/signal to the ECU to help induce a change.

Your box will be intercepting one of the signals so do you know which one it is; i.e. is it fuel cut or AFR etc etc.

Admittedly, I modify everything but I'll only ever modify the actual map to ensure that the Air-Fuel ratios are correctly balanced. That said, I always have to change the ECU to cope with the things that I want from a vehicle.

I would be interested to know what the exact differences are between the 130 and 150 lumps as in theory it could just be the turbo that's different with its variable AFR map to help support the more advanced turbo unit.

Son had his Ford Ranger with 44k miles remapped at a local place two weeks ago. It's the 2.2 diesel that's in a few motorhomes (Peugeot based ?) It seems a smoother drive now and has lost the exhaust "bark" that you heard kicking in around about 2000 rpm in the lower gears when setting off, he's averaging around 4 mpg better, going by the on-board computer. The guy also picked up on 3 glow plugs that weren't working that the main dealer had missed 2 days earlier while it was in for a warranty recall.

Funny that statement my remap was picked up straight away by reading even though the dealer had taken it off because one I hadn't asked for it and two I had spoken to fiat who as i said before told me all warranties would be void, the reading dealership did reset the limp mode which was down to an ERG code but told me they and any other garage would not do anything under warranty so when my new vehicle went into limp mode almost straight away one phone call to the dealer threatening court action got me an immediate refund without any argument I wonder why?

Now follow up from fiat asking me what had happened to my vehicle, (good customer service) told them I no longer owned it but did ask how they picked up remap as dealer said it couldn't be picked up answer was rubbish any action on something computerised leaves a trace and they could certainly pick it up.

So the bottom line is you have the pros and cons of remapping my view is if its under warranty why risk it for very little gain remember it is YOU who is going to pay the bills not people on here who are telling you its ok and can't be picked up, after your warranty well thats a different ball game I still would not do it as i now have an un mapped vehicle and the difference is not that great

I know I’m not val and John but hope this helps

Only Differences between 130 & 150 Looks like remapped and Variable geometry turbocharger

Thanks for that info, unfortunately I am not that mechanically minded what does variable geometry mean in layman’s terms ? as I am considering remapping the euro6 2.3 130 to whatever ?

That’s why I have a removable box , it would be removed if warranty work was needed , they can’t tell it’s ever been on

Scotch mist,
This is getting more interesting by the day !! What sort of performance do you get with the removable box and what is the bhp increase ?

It’s a plug & play box there’s loads of different manufacturers out there , I have the DTUK CRD3

Got this one for my brand new 180 Fiat Ducato MH
More sophisticated (£400)
It plugs in at common rail / cam sensor & somewhere else
Easily removed if I have a warranty problem & undetectable



Look on eBay and you’ll get a better idea what look like
https://www.ebay.co.uk/sch/i.html?_...570.l1313&_nkw=dtuk+crd3+tunning+box&_sacat=0

I have a very basic on on my Renault master van (£70 on eBay) you just unplug the wire going to the common rail & plug this in between , it has a dial that you turn the power up or down

they are installed after the ecu , once unplugged fiat will never know that you had one on so once removed doesn’t affect warranty

Both units work well , around 2mpg more BUT more torture & BHP
The difference in driving between standard & chipped unbelievable

I still would not do it as i now have an un mapped vehicle and the difference is not that great

Anybody who claims to have had a vehicle re-mapped and make such a statement has either A) had a very, very poor job done, or , B) just does not enjoy driving or does not know how to drive (sorry). If you like driving at 45 mph everywhere then there is absolutely no need to have a re-map done.

Of course for those particularly nervous types who are terrified at the prospect of ever having a problem and anxiously ask 'how much is a new clutch for my camping car'? the easiest thing is to leave it in the garage. You are guaranteed never to have to pay for a repair!

Our heavily re-mapped BMW car has just been to the BMW dealer to fix a cooling fan problem fixed under warranty, it was plugged into the computer etc as normal and no re-map was noted. I would be very surprised if it was found and certainly, none of the cars that we have ever had re-mapped have ever been discovered by the dealer and that is over about a 14 year period.

A final point for those nervous forum members. Why do you think that on the British MOT it is a visible check that is carried out to check that a car has not had the catalytic converters removed? Because the computers cannot pick it up that's why and if they cannot pick up a major part of the emissions system being chopped off (and bear in mind that the reason why a car runs with no warning lights etc after such major mechanical surgery is that the whole program and computer are overwritten to ensure that it is fooled?.

I think it very unlikely that they would be able to find a simple map change .

Re-mapping is a simple, absolutely safe and economic way of increasing driving pleasure and economy. It is not about ripping the car to pieces by spinning wheels etc.

Literally, we have driven hundreds of thousands of miles in re-mapped vehicles and never a problem of any sort never mind a clutch, gearbox or refusal of warranty claim.

Some people live to worry. Re-map and enjoy (and save money on fuel).

I rest my case.

Enlightening to say the least, thank you for sending this information I’m sure it will come in useful.

It's only safe when a.) the mapper knows what he is doing and b.) the engine is healthy enough to sustain the extra demands being placed upon it.

Sadly (for my bank account), I'm one of those guys who who falls within your final category and rips the entire car to bits in the hunt for a 4-figure BHP rating.

For info: I have a pal in Essex who placed a 2JZ GTE and V160 Getrag into a BMW 3- series and he has managed to produce 800BHP at the hubs. You may know him if you're on the BMW tuning scene.

EDIT: My mistake, the BMW is running 1000BHP. What's 200BHP between friends

And of course Paul or Val will pay for any repairs no longer covered by your warranties
