has anyone mapped a 318D and put an induction on it?
i know its not an M3 but just want alittle poke out of it, or will it just be wasted money? if anyone has, where did you get your map and induction? did any problems come after mapping and induction.

one day the 318d will go and i will get a decent ltr but for now its what ive got so might as well make the most of it

Pretty much all turbocharged cars respond well to a remap.

You'll certainly fell a difference.

I believe remapping an LCI is a lot more difficult & therefore more expensive than a pre LCI

i know that it is if the ECU has to come out, but the 3 places i have called and gave them my chassis number have all come back to me saying that mine can be done with the ECU in the car.

even though its only a 318 and a diesel 318 at that?

its a TURBO diesel though, so you will get a decent gain from a remap.

cool, i will give it a go.
i wanted to get an induction before the map, been adivsed if im getting on then put it on before the map as it is mapped on a dino. do you know where to get a decent induction from? the 320d induction kits fit the 318d right on LCI's?

[Icekube]

personally, the OEM filter is best.

after market "induction" kits allow some more air in yes, but they do it by not filtering the air as well, meaning shite that would normally get stopped by a proper filter, gets sucked through the engine.

I'd go to ptorque in wolverhamton, Will did my 118d 143bhp (same engine as yours) and remapped it to 185 bhp Made a big difference to the way the car drove.

I wouldn't bother with the induction kit, it might make a better sound but you could loose a few bhp due to heat soak from the engine. Also if you go for a k&n kit, the oil coating has been known to cause problems with the MAF sensor

thanks, i will give them a call. 185bhp?? i should notice that then haha

think i will stick to the OEM filter, sounds like the safer option, plus if i get to the 185bhp mark i will be happy with that.

[Dsport]

Agree stick with the stock air box and do some research on your mapper before getting it done,

What are the implications on mpg figures?
As you would buy 318d for mpg.

None I doubt as it's the same engine as a 320d plus mapped cars are generally better on fuel afterwards...

The mpg on my 118d went up by 3-4mpg when I took it easy, but that wasn't very often with the extra power

Will at ptorque writes the map himself, does a before and after dyno runs, he can cater the map anyway you want it. Max power, more mpg or a mix of both. He's not the cheapist but one of the best.

He can also bench flash encrypted ECUs

Cheers guys. I guess it improves the mpg if you are careful. But once you improve the bhp, you want to drive it hard and that is where mpgs go low.

Again shelf the airfilter idea

All they do is let loads of crap smash off your turbo blades as they are crap at filtering air. They let all sort through. Best sticking with a new oem paper filter

Diesels run on excess air anyways so you wouldnt even notice a difference

[Hennessey]

Thanks for all the input guys.

Booked in for my remap on 29/01 !
defiantly keeping the OEM filter after all your advice.
nice to see some diesel members tho! one more quick question.... where do you diesel guys get aftermarket parts from? ha-ha, i only ask because when ever i go on an aftermarket website (i work in an office so that's quite often) they normally only give me model options for like 325I, 328i, 335i, 330d, 335d etc....

once again thanks for your help and advice guys!

I really don't understand that! Fuel economy is the Holy Grail of all car manufacturers yet, even with the vast resources available to BMW, an aftermarket remap is able to improve power, driveability and economy - I understand that a remap squeeze more power from an engine, been there done that, but I really don't believe that BMW knowingly use a less economical map, particularly with euro legislation staring over their shoulder.

Even if we assume that maps are generic and are designed to work in different countries with varying fuel quality, I'm sure the ECU can be set make the most of where it is & what fuel is used, or simply use region specific ECU.

I'm gonna put my helmet on now and wait for the stoning

When they rest the fuel economy of a car, the official test is done on a dyno and only for a few miles. From memory it is something ridiculous like 7 miles in total.

I think manufacturers are wise to this cycle and all they are aiming to do is set the car up for this cycle. Hence why you get great figures that don't pass into the real world.

Low emissions are also their target which often means chocking power a bit.

[Maaarkk]

Sorry for the thread jack OP!

This sounds real good for the 318d if the figures are correct.. bringing it up to 320d level.

I've seen plenty of people talking about it before but it's one thing I never bothered considering.. But does anyone know what sort of figures you could expect from getting a decent map done to a pre lci 320d e92?

[DuckySpud]

I was confused about the increase in mpg after a remap too and a bit doubtful. Had a remap done late last year, mpg is generally around 2mpg better now, and that's with quite a bit more heavy footed driving!

It's not a massive increase, but very impressive to say there was a 40bhp increase at the same time

A 320d 177bhp should get about 220-225 bhp safely. Don't go to the tuner who claims the biggest gains, go to one recommened or you can trust.

[Jase 320d]

It should shift with that bhp

My bro has a 197bhp 325d and that shifts along well

If my older m47 163bhp 320d maps to 197bhp i'll be happy with that
