Remap

Just had my z4 20i b48 remapped at West Yorkshire Tuning, from standard 197 bhp 232 lb.ft torque to 296 bhp 307 lb.ft torque, the difference is incredible it feels like a different

Did the tuner give you any warnings of potential damage to the B48? I am wanting to do my 320i but I have seen a few warnings about (rare) piston damage which is putting me off TBH.

crikey, thats a massive jump! while 300bhp from a 2 litre turbo isnt unreasonable, it is a huge jump from factory!

hope your brakes, tyres and gearbox are up to the task, a 300 bhp car is fast!

I will be keeping up with the servicing every 6000 miles using BMW filter and oil

hi if you have the b48 B engine its the lower compression one .
only the A engine is the higher ompression.
B engine same as 3.0

Impressive results. That will be a lot better.

The BMW 330e a couple of videos below. Gains of 129bhp and 280nm up to 421bhp and 705nm.

I am wanting to do my 320i but I have seen a few warnings about (rare) piston damage which is putting me off TBH.

I briefly looked into this because the engine in my Mini (F56 JCW) is a B48 putting out c. 230hp. Assuming that this Wikipedia page is accurate: https://en.wikipedia.org/wiki/BMW_B48 I noted the following regarding the 225kW (302hp) version:

Introduced in May 2019 this engine features a reinforced crankshaft with larger main bearings and new pistons with a lower 9.5:1 compression ratio, this allows the engine to take more boost pressure from a larger turbocharger, which blows compressed air through a reworked intake tract.

No mention of internal changes up to and including 195kW (261hp) so if I had my JCW tuned my original thinking was to go much closer to the 260hp figure than 300hp. I didn't progress it in the end - keeping up with the minor hassles of one modified car (my MX-5) has proved sufficient.

Mine is an early B48 (2016) with 181bhp as standard, so presume it is the higher compression one. Not too bothered about doing it now, as the car is fine but would like a bit more 'shove' sometimes as it runs out of puff quite easily on acceleration.

This is the same power as a Cooper S, I think. "Only" mapping it to c. 230hp would be on par with a JCW and give you over 25% more power. Unless there are further differences between the two setups over and above the remap then I'd have thought you could assume 230hp was tried and tested given how many JCW hatches must have been built. But what do I know :idunno: (not much - you've been warned!)

Well the same B48 as mine was fitted to the 330i with 245bhp, so presumably that would be quite safe. Problem I have is my favourite 'chipping' company only do a 'full fat' 280bhp tune and have a caveat on their website saying, basically, it could go horribly wrong! The only 'man in a van' one I've seen at 240bhp is Celtic Tuning and I have heard conflicting stories about them. I am not going down the rolling road map route, as it's too much hassle and there isn't anywhere nearby (that I would trust).

bluespark box will give you 267 bhp on your 2.0 g29
can be removed with no trace .

Whilst there is no physical trace the DME and other ECUs will have logged the implausibly odd parameters that the box frigs

So warranty wise no great difference..

There will be a trace alright.

a 300 bhp car is fast!

An M40i is quicker oke: :fuelfire: :rofl:
