F20 116D mapping

Hi all,

Apologies if this has been done before.

My 116D's warranty is ending soon and thinking maybe mapping it - never done anything like this before so wanted to know how / what I can expect?

I don't want to remove the DPF and it looks like most sites suggest this as standard as part of a map.

What other components will need to be upgraded?

I don't want massive performance boost or a super fast car, I just want a little bit more grunt as sometimes the 116D can feel a bit lacking. What can i expect to happen to my MPG's as well? most sites suggest it will improve? is this true for real world driving?

Are there any drawbacks to doing this? Are there any risks of the car becoming unpredictable or unsafe?

Thanks

im pretty much in the same boat with my 116d tbh ive got an auto box in mine and from what research ive done its rated upto 450nm of torque, i think the 118d has an addition of an oil cooler and the 120d has better injectiors, i have spoken to what seems a pretty good tdi mapping specialist in trafford park in manchester which said they could get 170bhp without having any long term issues

I've had my 116d mapped, no supporting mods are required at all, dpf removal isn't required and any good tuner won't recommend it. My car is stage 1 and after a custom map is now 205.4bhp and 319.9lb-ft of torque. My mpg hasn't improved but it hasn't got any worse, claims that your mpg would improve when you've almost doubled the power would be a bit far fetched!

205 bhp!! That's a massive increase, almost double. And with no other components being upgraded either? Surely there has to be weak link in there somewhere with the car being built to only output 115 vs 205 bhp?

How long ago did you get it mapped? And has there been any long term effects or excessive wear on any other components (aside from tyres and brakes as that's subjective to the way you drive more than the power of the engine)

I'd only want to get to maybe 120D levels of power at most really. It would be interesting to know differences there are in parts used on the 116D vs 120D? which bits have bmw up rated for the 120D. I know the engine is the same, but is the turbo or anything like that any different?

You don't need to remove the Dpf
This is just away for tuners to get more money out of you cause they can't tune cars well

Who ever you use make sure you do your home work on them 100% and then do it again !!!

40% of my work is to fix other tuners work for problems they have caused like going into limp mode or not making the power they say (like 20 Bhp extra if your lucky) and when you go back they will blame your car

charge you to change parts like fuel filters, fuel pressure sensors, say they cleaned your air mass meter (when they have changed the remap files)and after still going into limp mod or you still have problems or not making the power after, they have given you another Dyno graph from someone else's car so it looks like you have that power you wanted (yes I have seen all this form other tuners and tuners on here)

Then when the tuner threatens you, fobs you off, ignores you and so you will

As for your 116d they will make good power and the car will be transformed

Yes, massive increase and as I said no components were required to be changed to support this at all. Before mapping, my car ran 121bhp so was a healthy figure to begin with. The 116d is the exact same engine as the 118d minus an oil cooler as I'm led to believe. As far as I know, the 120d has a different turbo and possibly different injectors but I'm not 100% on that.

I've had mine mapped for 3 months now and not noticed any increased component wear at all. I would 100% recommend having it done but as mentioned of you do go ahead, research the company you choose. Good tuners should be willing to let you watch them work and should be more than happy to let you watch all dyno runs and show you the results instantly.

Mine was done by ecotune as they were the best that were fairly local to me - the service was second to none and let me watch me watch every step and happy to talk through and answer any questions I had along the way. They encouraged me to take the car a test run after mapping but before I had paid to ensure I was happy with the service!

My car was done over 2 years ago by eco-tune, nearly doubled my power from 115 to 204 bhp and all standard apart from better brake pads

No loss in economy but more power when i need it, best mod i have done to the car

Thanks for your responses.

One further question for you guys, I have a service pack on my car, with another 2 years life left on it.

Do any of you guys have any problems with any routine service / repairs when you take the car back to a bmw main dealer after you've mapped the car?

If the Ecu needed to be removed and open then boot flashed on the bench as soon as the Ecu is read all the boot flashing tools will need to change the processor files
This will be easy for the dealers to see if the connected to the main diagnostics system

You can always buy a after market warranty

If you use a company who tells you take your car to bmw for a update after they have opened your Ecu then they have 100% damaged your ecu

Just out of curiocity, why is it that the 116d engine seems to gain more power than say a 118 or a 120d? I see people being quoted outputs of 190bhp from 116's, and the same again for a 118? Surely a 118d should be putting out a bit more power once remapped, than a remapped 116?

from what I have gathered the 116D and 118D are exactly the same mechanically, the 120D probably has some upgraded parts.

BMW have just mapped them differently and badges them up accordingly. sounds like c200bhp is the "most" this engine will safely give. so its kind of irrelevant if it was a 116D or 118D to start with i guess

make sense?

Ahh, ok. I always thought the 116d F20 was the 1.6 mini engine, and the 118d was a 2.0 BMW engine with the smaller turbo? I could be wrong though
