Finally got the time yesterday to drive the 300 miles to get my remap done after weeks of waiting to clock up enough miles to loosen the engine. Many thanks to the guys at www.kempower.be - they spent 5 hours tweaking my engine and I must say they have done a really professional job.

The car feels exactly the same until I gun it and then you can really feel the extra 60hp. The engineer who road tested the car post-op said he got wheel spin in 4th but, as I have to pay for my own tyres, I won't be trying too much of that, thank you very much

Final result, then: 283hp & 615Nm (449 lb-ft). Good enough for me

after the evotech thread, i can not trust dynos anymore. WOW...thats alotta juice you got there. that is the same as the 335 now...

[txusa03]

449 lb-ft (gotto love the diesel engine).

I can understand your skepticism - especially reading stuff like this on the Internet - but subjectively the car really does feel as if it's got an extra 60hp, no more, no less.

[Bravo1]

Man that is some massive torque! Doesn't rev all that high, but with torque like that... who cares! What PSI or BAR are you running now?

What's your redline at?

No idea. A diesel engine requires a different driving style: it's hard to explain to someone who's never tried one, but basically you use the torque rather than the hp and since this is available really low down the rev range, revving a diesel more than about 3500-4000rpm is utterly pointless.

Wow, the passing power on the motorway (autobahn, freeway, etc) must be MASSIVE. When I lived in Germany, I had an Opel Omega (company car) with the 2.5 BMW diesel motor in it... It was so awesome on the autobahn because I never had to downshift. I really miss that torque.

[Bravo1]

I know this is going to sound stupid, but are these adjusted dyno figures? Because these look like flywheel horsepower numbers and not at the wheels. The initial dyno is showing almost zero drivetrain loss and even for a BMW that is underrated, that is unusual. Do you have any other power mods done?

[canucklion]

OMG, you've got TQ and LOTS of it!

[ADHD]

I completly believe this dyno!!!

Diesel turbo engines are extremly detuned for car applications!!

60hp extra is completly normal!! I drive an 03 2500HD with a duramax diesel and allison tranny with a hypertech chip and its got almost 30hp gains!
Im putting on a full banks kit soon that assures 70+

You may be right. I can't say, because I wasn't allowed into the workshop. All I can say is that remapping turbo-diesel engines is very popular here in Europe and Kempower in northern Belgium have one of the best reputations - that's why I was prepared to make the 2 1/2 hour drive

[ksfrogman]

Diesel engines always have a lot of torque because of high compression ratio, but they are usually heavier and rev lower. This is why they are great for towing applications. They also get great gas mileage and last forever. Wouldn't it be great if you could just take the diesel crankshaft and install it into our cars for a longer stroke?

[Bravo1]

Either way your gains are impressive.... 56 hp and 73 lb/ft torque increase just from a flash. If the dyno did not calculate drivetrain loss, then your numbers at the flywheel are just insane. That would put you well over 300 hp at the flywheel and over 500 lb/ft of torque.. which would be gains of 70+ hp and 130+ lb/ft. Either way, sweet ride Now go smoke them rear tires up haha.

Lol, yeah I think I'd better start buying shares in Michelin

I'm currently driving the last days with a E46 330d, which came standard with 184hp. After a treatment at www.kempower.be too (back in 2000) it has 225hp and 500Nm . I must say these guys are really good. I was a bit concerned that the remapping would reduce the engine's lifetime, but far from it! I've now passed the 315000km mark

In 3 weeks I'll have my 335d and I'm seriously thinking of spending about 800 euro to let it remap again. I'm just not sure what that would give in numbers of hp and torque...

[Paul330d]

315,000km?! Wow, that's good to hear. I believe Kempower are still developing the remap for the 335d, but I'm sure you would be good for about 350hp & 700Nm They advised me to wait until I had done at least 5000km, though, and as it turned out, I had done 11,000 by the time they got their hands on it yesterday. Best €800 I have ever spent - go for it

[jvey]

Yeah 315000km :rocks: and taken all into account, no mayor malfunction. At least one that could be caused by the remap...
The only time I was really scared that I had to spend my last eurocent, was when they told me that my "bottom-plate" (sorry don't know the word, litteral translation from Dutch) was broken due to the torque...
Luckily I wasn't the only-one, and BMW repaired for free

[Paul330d]

Now you're beginning to scare me I have heard, however, that the e90 has been considerably toughened up compared to the e46 (brakes, clutch, etc), so let's hope they did the 'bottom plate', too

[tl_boy]

paul, those are some impressive results... any pics, vids of your car??

[Dr Noelle]

I have personally driven several diesel's E46 and E39's... and the torque at is amazing... With auto transmission even better.... All US states, apart from California, should have the choice to buy one...
