    Dont bother mate. Too much moral high horse nonsense on here. What you have done is not that serious as you still have 3rd party insurance cover so the only victim would be you, financially. I never

I told my insurance company about the car being mapped when it was done but they werent interested and told me it wouldnt make any diffrence to my premium.

Lets hope mine does also then because with everything going up in price and wages being frozen we could do with some help.

Who are u with?

Cost the same for me too, but I had to tell them when the map was removed as the details on the certificate must match those of the car. Their words not mine.

Yes it can indeed improve economy as the increase in torque the car now produces aids it by allowing you to use less throttle to get the same results during acceleration thus saving fuel.

Sorry, but no.

Having more power and using less of it does not in itself save fuel. To save fuel you have to make efficiency gains. The standard efficiency gains are made by undoing emissions controls (EGR and timing advance).

For example, remapping a euro 4 car and advancing the timing will likely put NOx emissions past Euro 4 and back to Euro 3 standards.

Im with RSA but they can be funny when i phoned to insure my car told them it was lowered had aftermarket alloys custom exhaust tints etc but they said it was only top speed enhancing mods they needed to know about. But when i went to insure the mrs leon told them it had alloys and tints and i was told that would put the premium up. Then when i called after the map was done it was a case of ok thats fine.

Point taken!

A remap wll not invalidate the third party bit of your insurance cover, there is a specific part of the road traffic act that states changing engine power will not invalidate 3rd party cover. The insurance company would then probably try and recover what they paid out in 3rd party claims from you, so you would not commit the offence of no insurance but it would be expensive for you!

Not telling your insurance would however mean that they wouldnt pay out for your car should you bin it.

Not having insurance can render you personally liable for third party damage/injury. You could end up destitute, bankrupt and homeless, given a "good" scumbag lyer

Very interesting subject. As a thought, what happens if you buy a S/H car that has been mapped with out you knowing (mine has been in the family from new) A little worrying for sum i bet.

I think you might win a battle with the insurance ombudsman if it was something you genuinely didt know about and insurance refused to pay out, especially if it was something not easily visible.

For example if i buy an older car how do i know if the stereo is modifed or not? or if the wheels are standard? or if the leather interior is standard or retro fit?

Good point, and one that struck me when I part ex'd my vrs. The dealer knew it was remapped, but I'll bet they didn't reload a std one before selling it. I know it still has the shark sticker on it, so at least a potential buyer had a clue.

There will be a plate/sticker on the car with various factory option codes. The stereo, wheels and interior trim, and the engine type and output will all be listed as to how the vehicle left the factory with specific codes.

On the Octavia, there are stickers in both the service book and on the boot floor by the spare wheel.

Mike

But would the average joe know what these stickers mean?? of course they wouldnt.

I am very much in the declare everything camp but i can see the other argument.

Most wouldn't, but apparently there's a look up/decoder somewhere on here. Bet you can't find it...you have 20 seconds to comply...

To be quite honest I would sooner me and my family be driving on the road with people who have mapped their vehicles than people who go out there intentionally drink driving. I know which one I think is worse.

Just a post for food for thought! (I'll get my coat)

Lesson learnt here from me chaps, but I tell u what why don't we actually talk about what the post was started for, 'Remap and Subsequent Fuel Efficiency', we've gone off topic!

Well, that was my bad I guess as I asked about insurance too!

Lets hope you never have a accident where you write the car off or even worse there is serious injury or a fatality.... I think you might be surprised how easy it to tell if its been remapped. There are a lot of insurers happy to insure mapped vehicle .. some of the comparison sites even have an option for maps now... it wont cost you a lot if any more in premium.

From a technical point of view (avoiding all the insurance arguments for now), it is not easy to tell if a vehicle is mapped.

You need to pull out the current file, find a copy of the original file (not easy at all) and compare them both.

I have a scout and managed to find another original scout ECU file on a tuning forum. They were over 2% different in stock form. There is far less than 2% difference between stock and mapped.

This shows that simply comparing files is of no value at all. You need to find a tuner who can identify the key maps and compare those. Even with all the hardware and software, this is not always an easy task. It can take many hours in some cases. There are over 300 maps in my ECU.

Any ideas what remapping does to warranties?

Depends on your dealer. Skoda UK would probably not support any claims that could have been due to the increased stress on the vehicle, whereas the dealer might (and some openly do as they offer their own remap service apparently). This is assuming that they can even find out is been done, hence the popularity of switchable maps.

Road tax is set for the vehicle based on the original figures

Yep

Theoretically you can put a V8 in a prius & pay the same, Ok the tinfoil pile of pooh will probably collapse under the weight but it sort of feels fun to drive a Prius burbling down the road & spitting fire from side exit exhausts.

Theoretically it can have an effect on some items that could directly suffer as a result of the extra power, ie if a gearbox fails or a turbo blows but a leaking door or heater failing cant be caused by a remap. Dealers get paid for warranty work so I guess will be sympathetic up to a point. In honesty the power increase is so small I havent heard of anybody having failures due to just a basic remap, the only rider I would put on that is get the remap from a reputable tuner, not something cheap advertised on the web. With remaps like many things you get what you pay for

Hmmm thanks, I've been thinking about a remap especially as it appears to improve fuel consumption but I'm not sure whether warranty direct would whinge or not.
