What exactly is ''remaping an engine''
Remapping means that the ECU or engine management system is altered electronically to optimise performance. The manufacturers generally limit their outputs in line with tax laws and or for overall longevity and operating parameters such as high/low temperatures or humidity. The companies that remapp glean the best power and torque curves whilst making sure that reliability is retained.
The bonus is that sometimes this improvement can result in better fuel consumption.

120deman said:it is BLOODY QUICK!!!!!
The delivery is so much smoother, you have to look at the speedo and what before seemed like 60mph is now 80mph.....and it gets there quick....
.that's in normal mode. Sport mode is wuicker still, but stick it in Steptronic and you've got a rocket.
Jason told me to drive it hard for 100miles before the remap really takes effect.
When he test drove the car after the remap with his Dad......they couldn't believe how quick it was........and came out of the like 2 grinning cheshire cats.
Jason is a top bloke and I would highly recommend him......he certainly knows what he's doing.
As I'm driving more, the car is definitely getting quicker.
I'm pulling away from the lights with much less turbo lag than before....which was one of my major gripes about the car. Other cars are left behind easily. The whole rev range is so much more accessible resulting in an even more responsive driving experience.
It's also smoking less than before under hard acceleration.
I used to get on average 29mpg, the remap is supposed to increase this by a few mpg so I'm keeping my eye on this.
I'm definitely impressed at the moment by the transformation
guardianangeleyes said:well i took my car to Chipped Uk in Bromsgrove yesterday, they did the remap and put it on their rolling road ... the outcome one very very fast one series i was amazed at how much smoother the engine is and it pulls incredibly well in every gear ( but especially 2nd and 4th for some reason ) it was a 200 mile round trip to bromsgrove but worth every meter .
They are nice people at chipped uk , with a very professional setup like 120deman says i too could recommend having it done to anyone !
( a little advice though ... in my experience i found it far better to go direct to bromsgrove , rather then one of their local dealers ... i wont go into it what happened , but i didnt have a very good experience the first time round
suaves said:I have also had my 120d done by Jason and I would v highly recommend him. My car flies now! Took me a while to decide to take the plunge, but sooo glad I did.
DMSsmithysmith said:I contacted chipped uk and they put me in touch with Rob at chipzone who does their mobile service for the south, the car was booked in later that week at my place.
The performance increase wasn't immediately noticeable, but when i opened the throttle the difference was amazing.
The car is now seriously quick, and the torque is delivered from about 1800rpm (same as standard) all the way to the red line.
Chipped UK estimate about 210bhp and 420nm of torque i haven't had dynoed but the performance indicates a good power increase me thinks.
30-60 in third was 5.5 now 4.6
50-70 in third is now 3.3
30-70 using second and third is now 5.9
To sum up: If anyone is currently considering a remap i definitely recommend chipped UK, their prices are VERY competitive too.

shep said:Current MPG has improved since DMS from around 28mpg up to 30 mpg after 12 k miles - though economy isn't a major factor - it is a 3 litre engine. Most of this is long distance motorway runs - it can drop below 10mpg if you try.

Superchipsgraham said:I have just purchased a Rail K tuning box from Speed Buster at a cost of £63 and it works perfectly, no black smoke and loads more torque.
I have absolutely no complaints about the fueling maps which seem perfect.
Very nice delivery and very very fast!
One thing I have noticed is that fuel consumption suffers terribly on full throttle (15mpg) but it does fly.
I assume this is due to the extra fuel being used.
When I drive it on part throttle I am actually seeing gains in fuel consumption though which is a bonus.
Checked with the manufacturer and it is a digital tuning solution, not a simple resistor (thought so as the mapping is really nice)
It also seems to have settled down and I am now receiving 42.8mpg with regular driving, which is a slight improvement.
Obviously if I use full throttle, the consumption goes down though.
This is an excellent product, extremely well made with BMW wiring covers and connectors and fits (ridiculously easily) snugly under the engine cover with no rattles.
I asked them to reiterate why it is so cheap (buy it now for £100) and they said it was because they are the manufacturer of most tuning boxes on the market hence the saving when you go direct.
I would recommend this to anybody over and above more expensive tuning boxes that I have owned.

gtfire said:Superchips were great to me and gave very good customer support + they come to you if you want, so no long trips out.
The extra power made it the car it should always have been - BMW hold back the power so not to upset the 130i boys ( and girls sorry 130 girl )
Just remember that a box in the engine bay is not nice if you have a prang - a remap is just about undetectable, but if the worst happens it could be traced so consider getting proper insurance - I did not but I would in the future.
Oh and haggle I got £100 off just like that.
0-100 mph 16.24
0-60 mph 6.84
50-70 mph In 3rd 3.38
30-70 mph Through gars 6.08
FUEL CONSUMPTION PRIOR TO CONVERSION 35.6 MPG
FIRST TANK AFTER CONVERSION INC. FULL TESTS 34.8 MPG
Please note:-
Surface was part concrete part tarmac Disused runway
All standing starts were done in dry conditions with DSC fully OFF.
We were very careful not to damage clutch or drive drain.
With this in mind I believe a couple of tenth quicker could easily be achieved for the 0-60mph
No allowance for speedometer inaccuracy were allowed so 0 -100 could be easily 1 sec slower than times stated.
We Had 1/2 tank fuel with 2 persons in car.
Temp 24.5 deg c Sunny.
ALL TIMES WERE BEST TIMES ONE WAY ON LEVEL SURFACE.
DragonSothern-Monkey said:Hi, I have a 120d and had superchips ramp up my car. but before I did I took some timings.
50 to 80 in 4th was 9 seconds
70 to 100 in 5 was 13 seconds
70 to 100 in 6th was 17 seconds
After I had the chip done I did some checks and noticed that the car left these times behind, but I did not write down the new figures. I can also hit the end of the clock wich is 155 on a long run, but it gets to 150 no problem. I have a picture with the needel at the end!
hope this helps.

Ash said:fitted my multi map box yesterday which was easier than fitting it to a vag pd engine, apart from connecting the positive lead to the fiddly nut behind the jump lead terminal.
i havent touched the settings so its on 0 setting i think with +3 being most powerful and -3 being for mpg.
i would estimate theres upto 10% extra power. very smooth and no black smoke.
at first i thought it didnt work but it doesnt cut in til the engines warm apparently.
im not gonna mess with it too much, especially at this stage, cos the cars only done just over 1400 miles so theres probably more loosening to come.
so far its the perfect mod for me. the car feels so petrol like with its revvy smoothness compared to before, where it was almost too obvious that the engine was being held back for emissions ratings or whatever.
for what these cars cost, my view is its def worth paying a bit more to get a better return in performance which now compliments the handling and overall driving experience
bazzagt4 said:I have the Dragon tuning box and found it to be excellent quality and provided me with a nice smooth increase in power while still keeping a good MPG figure.
Brought it from dragon direct and not from ebay.......good customer service and great instructions supplied.
9/10 from me
DPower said:I've too installed a Dragon box recently on my 120d. I've played around with virtually all the settings and personally found the standard 0 setting to be the best for all round power and torque.
In the Dragon manual it does say increasing the jumper from 0 to +3 just shifts the power band upwards. Therefore putting it onto the +3 setting gives you more higher end power. Personally, when i shifted it to any of the + settings i find the car runs less smooth which gives the impression of less power.
MoreGomad-marco said:got round to fitting it yesterday (it's really easy to fit). So far so good, the engine is smoother at low revs (below 1,750rpm) and pulls better throughout the rev range. Accelleration is better so I'd say generally I'd say it's a success.

TunitJezyG said:Took my 116i to MoreGo in Brackley to have the ECU remapped. Took around 2 and half hours but the service was excellent and had a good walk round Brackley itself!!
As for the end result firstly I found my mpg went from 34.4 to 37.2 driving the same route in the same manor. Performance wise throttle response is much improved. Pete did say that the original map had a big hole in it which would result in a flat spot. Exactly the same as a 2 litre Z4 he also remapped!!
The engine does have more verve although with only 400 miles on the clock the engine is still too tight to really be able to tell and open her up!
Torque arrives much lower down and I would expect once run in performance to be between a 118i and 120i. The lower final drive ratio giving the engine a little more torque at the wheels than a 118i that has a higher final drive ratio.
It cost me £399 including fitting. Not that cheap but still cheaper than buying a 118i in the first place!
