Hey just had my Cooper S remapped to 217bhp and 269lb-ft torque

The torque figure seems very high - has anyone else had figures like this?

 

bhp or whp? high for whp, bhp is just a wild guess unless you removed the motor for an engine dyno

 

Its bhp not whp...

It was done on a dyno before and after the remap

Before I was getting 185bhp (mods before hand were CAI and 2.5" straight through exhaust)

Its more the torque that impresses me though

 

32hp from a remap? seems plausible. forget the numbers themselves...it's the delta that matters. What tq increase did you see? Turbo cars almost always have more tq than hp

 

Remapped with what? Quoting bhp assumes a certain frictional loss, do you know what number that is?

 

Torque before hand was 205lb-ft torque - measured on the same dyno as the post remap one

Remapped at a specialist tuner in the UK - not sure of the frictional loss we used but the test was done in 5th gear and the before and after dyno figures were quoted
The before hand ones look realistic

 

4th gear is the norm for pulls. Is there a reason they used 5th?

I'd ask to see before/after AFR's and also boost levels.

 

Does the car drive like it has a boat-load more torque? Since it was done at the same place that sold you the "tune", it's super easy for them to fudge the dyno numbers to make them look good. 64Lb-Ft from an ECU reflash is hugely unlikely without pushing the edge of the envelope way beyond what ALTA did with running 20psig using the UNIchip. Do you know how much boost your car is running now?

Specifically, Who did the tuning?

 

who remapped it for you?

 

in 4th we were just getting too much wheel slip on the rollers... so we had to use 5th.. but the dyno was adjusted so it knew it was in 5th.

The car drvies fantastically yeah, the torque really is phenomenal
PSI figures.. Im not sure but I will email my tuner now and get the exact data from the map.

It certainly feels like a completely different car

 

Performance-Torque (or P-torque as they are know) In Wolverhampton, Uk

 

Wheel spin on the dyno rollers with only an alleged 269Lb-Ft? I've never heard of such little torque causing a problem with wheel spin on a chassis dyno. What dyno, tires, and was the car even tied down?

Glad to hear the car drives great; I just hope "P-Torque" knows how to competently tune a turbo DI engine. I'm impressed they have hacked the ECU and managed to not tell anyone about it.

 

I actually put my full review up here :
http://www.mini2.com/forum/2nd-gen-e...-cooper-s.html

Ryephile - sorry I dont really know much of the technicaly data other than figures. The Dyno.. all I know is that it is an italian one (sorry if thats no use lol), tyres are Falken FK452's and we struggled to tie the car down properly (which was probably the reason for slippage) because of how low the dyno machine was and also the positioning of the 'hook' on the right hand side of the car meant that the left wheel wasnt being pulled down on as much and was losing traction. We got round this by moving the harness and applying pressure onto the other side of the car

What figures do Alta quote from the Uni Chip?

 

Update:

I am running 1.35bar - which is 19.58 PSI

 

I've seen 700whp 'creep' on a dyno. I'd say you need to have your car properly secured to get an effect tune. A 'loose' car and +64 in tq? If it were mine, I'd insist on getting it done again to ensure I've got a safe tune (ask for an AFR plot!)

 

I replied with my inquisition on the original mini2 thread, since P-Torque is a sponsor over there. Hopefully they belly-up to the keyboard and offer some good information as to what they're doing. Right now if I was in your shoes I'd be biting my nails that my car won't blow up. If they come back and say they're running more than 20psig on your car, be mad that their tune is overambitious.

Ok, 1.35 bar = 19.85psig, or less than 20psig. ALTA runs 20psig with their UNIchip and they claim 20wLb-Ft gain. This is believable as the stock turbo is already very close to maxed out in flow-rate from the factory.

 

That's exciting to hear that someone besides UniChip is tuning an R56. Like everyone else said...I'd love to see an A/F chart, that torque seems pretty high! Nice though, I bet you're lovin it!

 

ive been speaking to the guy via emails and he says he has been working on minis and other cars for years and has never had a single problem, he doesnt seem like the person to fiddle with numbers.

 

For the record, with a DI setup you can run much leaner than port injection and still be safe. How lean however I have yet to determine [or hear about]. The stock tuning runs ~14.7:1 at the leanest. I would be nervous with anything leaner. Remember that "peak torque" no matter what with gasoline is still in the 12.8-13.2:1 range. With port-injection boosted cars the "rule of thumb" is to subtract one number from the AFR, so that means 11.8-12.2:1 is "safe". On DI, we can run exactly at peak torque for that engine because the mechanical quench is far superior.

 

Rye - only way I can really show you the torque is ask for you to do a 30-70mph test (as per the video on my Mini2 thread) and see if you can get close to the times.

The torque feels very strong throughout the revs, and at no point does the engine feel like its struggling - I dont know what that would feel like tbh - but it certainly doesnt feel stressed even when driven hard.

I will enquire about an A/F chart as it's something I too would like to see.

There are 2 companies AFAIk in the UK that do remapping on the new R56s and the other company tune theirs A LOT higher than P-torque (240bhp from just a remap not sure of the TQ) I think that this is pushing too much from the turbo (that is almost 70bhp over stock)

 

who are the other company?

 

That's crazy! What company is it, do you know?

 

They are called Paramount Performance.. I believe their product is a tuning box...

They were banned from Mini2 forums but they still offer this tuning box / remap I think. I know someone with it and he says it is fantastic?

 

Hmmm, according to their website they ship their tuning box worldwide...

Someone be a guinea pig here in the US!
