BMW 1 Series remap potential

[150234]

So basically I have just bought a 2013 BMW 116i with 136hp and was wondering, If I took it to Celtic Tuning what potential gains I could see from a stage 1 and 2 remap. I have been on their website and to be honest, their results are terrifying, at least In my opinion which is based of off my limited knowledge, hence why I am asking on here.

Standard: 136hp and 220Nm
Stage 1: 167 hp and 250Nm
Stage 2: 203hp and 309Nm

That maybe right, but to me the stage 2 remap seems very extreme and agressive for what is a small(ish) engine at 1.6l. Again, my knowledge is limited but a 22.7% increase for stage 1 and a 49.2% incrase for stage 2 respectively seems very large.

The torque gains, especially on stage 2, seem very drastic to me but it will be interesting see what the experts think. If I can safely get these results then that's great but I don't want any nuclear bombs going off in the engine bay. If I do this it will be rolling road tuned and have a specfic map drawn up for this car and won't just be generic map.

Thank you in advance.

Didn't get any luck with this post in the techinical part of the forum.

I think on these the engine is identical bar the mapping for the 116/118/120 etc.

So all you are doing is making your engine the ‘standard’ of the more powerful models

[Mirinjawbro]

what do they say is required for stage 2?

[Pistonheader101]

wouldn't bother if i'm honest. puts premature wear on the engine.

They didn't say anything about stage 2 requirements. If they had said you need this and that to make this work then I would feel more comfortable but they haven't.

Yes but the 1.6 litre petrol only goes to 170 but they're suggesting running it to 200hp. That seems like a huge jump.

It's the same 3 cylinder engine as a mini cooper.
Im sure there will be plenty of info on mini forums with owners who've gone down that route. I'd search some of those out.

[sherman]

Stage 1 is possible with remapping and maybe something like a better air filter or exhaust but stage 2 must need a new camshaft at the very least and has much more potential to blow associated bits of the car apart like the gearbox or diff which wont be changed from the standard.

[MrGTI6]

Your car has a 1.6 Peugeot engine that puts out up to 270bhp in the RCZ R and 308 GTI, albeit with forged internals. The 114i, 116i and 118i of that age all used the same engine in different states of tune. You'd get exactly the same results with a 114i, which starts out with about 100bhp!

It's an inline 4, not a 3 cylinder. This car is before the days of BMW's 3 cylinder engine.

[150234]

You sure? Just seems like a lot to me but I am undecided as to what to do. One the one hand I want a faster car, but on the other I would rather not blow it up. So do we think 200hp is okay? If Celtic have a warranty that would make me feel a little better.

Ah right, fair enough

A stage 2 remap is reliant upon other mods for a start, but if I was considering a 50% hike in power, I personally would be think of braking/handling mods first to ensure the mads will be safe to exploit.

IIRC as above the 116 to 120 all are the same engine so in real terms the actual gain over design of the 120 isn't as big a deal as you are thinking.

[Jazoli]

Why did you buy the second slowest in the range if you wanted a 'faster' car, surely you'd have been better buying a higher power version in the first place?

I'd be more concerned about timing chains and oil consumption than 'remapping'

There was a post on here a while ago from someone involved at BMW about the differences in piston materials and other engine internals between different output versions of the same basic engines so they could reliably cope with the demands of making more power. The sort of thing the tuning guys just gloss over.

I think remapping a 9 year old BMW is asking for trouble.

[Haltamer]

It's their product; They'll probably have the answers - Dubious "Stage 2" maps with no additional hardware always seem a little sketchy to me.

If you want to go faster, In this order, I'd say:
Driver training
High quality tyres
Then you can consider power.

[PH User]

You would be better asking on a dedicated BMW owners club.

Maybe just go for a remap, the engine will be fine if it's not pushed too much.

If it was me I would probably just sell it and buy something faster to start with.

[J4CKO]

My 1.6 is putting out 300 bhp, would find out what the conceived wisdom is about mapping that particular engine, there was someone on here who broke theirs but not sure if it was the same model as yours.

Yeah the stage 2 remap isn't suitable in my case.

Why the braking and handling mods? I only want it for acceleration. I don't plan to track it nor do any kind of fast paced driving around corners. I literally just want to be able to fly up a motorway slip road.
