Looks like a nice setup drivability is so important. How is the acceleration compared to the previous map?Tuning completed
just a stage 1 remap but what a huge difference to stock and previous tune!
Can’t recommend the Sunderland Performance Centre enough, the whole experience was refreshing from a car tuner as they were focused on what I was trying to achieve; in my case no interest in headline numbers after last remap (which was insanely quick) but all about drivability..After a decent chat we agreed a number of outcomes I wanted and they delivered, see attached for the results - well chuffed drives like a hot Mini should with power increasing as revs rise and not dropping off like stock, credit to the guys at SPC for achieving this
Ps - if you’ve had your mini serviced recently and going for a remap advise your tuner as the latest software update is locking the ECU meaning it needs to be bench flashed which takes a bit more effort
Hey, decided to join
LCI 2018 MCS no GPF, 7-step DCT
JCW stock exhaust with res delete
stock Primacy 3 non-runflat tires (Pirelli snowcontrol 3 in winter)
there are more mods coming and there is still a lot of work to do, haha
195 hp / 311nm - STOCK (192 hp / 280 (300) Nm is rated by BMW)
260hp / 400nm - REMAP

We're still under development and we will probably make some changes.
The new 7-step DCT is rated at long-term maximum 320nm, worried a little, but it is ok so far, no slipping, no sounds, shifting smoothly. (READ UPDATE)
But my stupidity showed up, when the custom map was made, I was running RON 99, then I after the remap I filled up with RON 95 and it made so big difference because the map was made for 99! It started to be jerky and unstable and ECU was cutting power to prevent damage, then I filled up again with 99 and it was getting better again every minute.
My mistake, nothing happened, lessons learned.
I was a bit afraid of knocking and detonation, it is good now with premium fuel.
Keep in mind, MCS has a compression ration of 11:1!
If anyone is considering a remap around and above 400Nm with this 7-step DCT, be aware that the clutches can get hot and you get a warning and the power cuts to prevent damage, it only happens when you abuse the engine and transmission, it needs time to cool down, same thing when you use launch control, IT NEEDS TIME TO COOL DOWN!
This might be a proof why the clutches were rated at 320nm, the transmission can do more, it is just the clutches.
If you don't abuse it, nothing will happen and no hot temperature warning, and ECU cutting power will happen.
Also consider halving the interval of the transmission oil change (not mechatronics, it's fill for life), normal interval is 120.000 km, if exceeded by 3000km, the clutches need to be replaced aswell, got this info from a MINI/BMW specialist. So go around 60.000 km and don't abuse the transmission by accelerating hard every time in a short period of time, give your good ol' transmission a chance to cool down a bit
Also running a second full tank of premium petrol rated 99 RON and it is running smoothly.
Don't forget to frequently change oil and don't use that 0w20, I think it is not enough for this engine, especially when remaped to such a power.
I use Ravenol RUP USVO 5w40 for summer and Ravenol 0w30 for winter.
I have the helix 6 paddle cerametalic clutch from lohen also with the single mass lighter flywheel... it’s great for hooning around but is annoying in stop-start traffic, as it can be quite grabby at low speeds. If you get a gear change wrong then the lighter flywheel will make you pay for it also with a friendly jolt! Basically much less forgiving, but as you say can handle up to 700nm so depends on your plans really.Brief update on my Sunderland Performance Centre remap...it's gotten stronger and is really drivable - love it! I do however have clutch slip (the previous remap ay nearly 500NM has clearly 'hurt' my clutch) so I'm researching options as whilst the Lohen Helix kit looks mega its probably overkill being rated at 700NM (i'm on 420ish...). Also, I have fitted a standard JCW exhaust which is a nice cheap OEM mod as its both louder and has more pops and bags than stock
So any other ideas on upgraded clutch much appreciated please and i'll share any feedback I obtain too.
Worth just checking the break in period for Kevlar as I think it can be quite a long time before you can put full power through it, but Kevlar will be super durable I think so good for a really long time.Boom first reply in from eBay seller techniclutch and it’s looking good:
The entire package is suitable for up to 480NM max. It will give a nice smooth drive too and the longevity.
- LUK dual mass
- Uprated pressure plate (circa 30% greater clamp force). Balanced.
- Uprated carbon Kevlar lined driven plate
- release bearing
- new set of flywheel bolts
- Liqui Moly gear protect additive
The cost is £475 including delivery.
The JCW clutch is also common to the Cooper SD and various BMW diesels. Can't find information on its rating, only reports from tuners and drivers. Seems to be a stout unit that can take stage 1 power without issue, also plenty of people running stage 2 woeless.Could the JCW clutch plate be an option as rumoured to have a higher torque rating but can’t find any info.???
