remapping a 3.0L deisel??

depends how you look at it, you are getting the performance of a much bigger car for a £500 tune up, you pay more to insure the more powerful model either way. Say you are looking at a BMW or Volvo diesel, quite a number of them are the same engine sold in different states of tune, you buy a low tune model for £1500 less and tune it to better than the more powerful one. Have a look at the BSR website and their guarantee as well as the tuning results. Google just about any sports diesel and add bsr after the model to find reviews. If you dont like fast cars you'll consider it a waste of money, how would a BMW 123d drive with 239bhp? well its acceleration times are between 11 - 17% better tuned, the throttle response will be dynamite etc. A Saab TTiD 130 bhp tunes to 213bhp and gives a 39% faster acceleration time from 100 to 150 kmh. just a couple of examples. Marmite.

I think its well worth doing - on the bangs per buck stakes its a very good return.

I'd a Clio 197 last year and with a full induction kit, free flow exhaust system and a remap i'd have spent probably £1500 upwards and got maybe 15BHP. Remap a similarly powered diesel and you'll get probably 40BHP for £300 to £400.

I've a Volvo T5 2.5 petrol turbo at the minute - it has a tuning box on it now that takes its power from 225BHP to around 265BHP and it cost £175. Well worth it in my book, and makes it a very rapid but understated Q car.

A remap wont incur sooty smoke. Any that are doing that are usually old fashioned diesels with the pump turned up OR cars running with turbos or injectors on their way out.

Was the TTiD not 180BHP, not 130?

Surely the 130 was the standard diesel? It would seem a waste of twin turbos and produce only 130BHP?

Amazingly, no. TID available as 120 and 150BHP. Later TTiD available initially as 180BHP with 160 and 130BHP added later.

I have a 3L bmw X5, its a deisel which returns a reasonable mpg if driven reservedly, has any one remapped a car, if so what were the benefits to it, better economy??:D

I had mine remapped. The main benefits were a lot more power. Economy is the same or slightly worse and it has also added a fair chunk to my insurance premium.

If you consider the cost of the remap plus the ongoing extra cost of insurance, you might break even in a hundred years or so if you drive like a granny.

ETA Can also confirm that a proper remap will not generate smoke. My car has been running with a remap for five years and the tailpipes are still shiny stainless steel on the inside just like when the car was new.

Mr.Generous

Mine is also mapped, it was done pretty much from new, its now 8 yrs old. I service it myself, it has had no main dealer work. I did get brakes and pads done for me once when working loads of overtime and just no chance to do it, otherwise everything done myself.

It doesn't smoke. It has passed al MOT's. I doubt you get any extra real world economy because you cannot help but use the power they drive so nicely. You can shake most tailgater's off on the motorway when a gap opens up. The torque and the power delivery mean you get an instant shove in the back from a very light touch on the gas. I can see why people wouldn't like it, not for everyone. I had an Astra CDTI remapped a few years ago and it was just raw and savage. Most aren't they can be used gently too. Each to his own. I suppose there are some merrits to a nissan micra 1.0

And what about insurance?

When I was younger I had to use flux, it added quite a bit on the premiums, about 50% when I had points. Now not so bad and some mainstream insurers will accept mapped diesels. You're not going to get the cheapest quote, but I'm over 50 so its not bad, plus its one of those indulgences like holidays I don't mind paying for. I do less than 6000 miles a year as its not used for work, that probably helps too. In the days when you used to phone for quotes I used to try and claim they were mapped for economy, well - I was young and hopeful.

So an old fashioned diesel (most likely simply with the pump pressure increased) and purposely adjusted to do that for dramatic effect.

Thats mad. :eek:

Presumably - as has already been said - a detuned version of the 180BHP version to gain the economies of scale, and hence why it remaps to such good gains.

All cars bar my first have been mapped, albeit not for economy. As far as im aware, most diesels do return better mpg once mapped

You'll get a false positive from the trip computer when its been remapped. They read "out" a bit.

I think theres a slight increase in economy, but its never been my primary motivation for doing it.
