I haven't seen Pendle show up on the BMW forum here yet, but they do deserve some credit!
The car : 2010 E91 LCI 325d (N57) 75k miles

I spoke with Collins of Probus in Cornwall who are agents for Pendle and they were very helpful and very knowledgeable about remapping and explained the emphasis is on a smooth healthy map instead of just getting power.
They said how good the product that Pendle produce was for this reason and why they use him..... They weren't wrong!

So this is a custom map, they check the car for codes ect, run it on the dyno and make sure all is well, then send the file off to Pendle who will tweek it and send it back, this goes back and fourth till they are happy.

They explain how each car is different and said my car got some really good figures and they were pleased with it.

i'll let the maps do the talking later but as for the drive here are my impressions.

Start up and idle is as per stock, pulling away and crawling around the carpark is all perfectly smooth and easy to drive ect.
pulling out the junction with small throttle inputs the car feels very smooth, i did notice it had more power right away at light throttle as i could use less to get up to 30 at a steady pace....
up and down the speed limits its butter smooth and a joy to drive, all at light throttle.

Then you roll on the throttle and a wave of torque hits you and holds you back in your seat, all beautifully smooth but so much! the rate this thing picks up speed is crazy now! i see why people rave about mapping these.

about 2/3rd throttle is more then enough and full throttle is another level. But its all so smooth and perfectly fuelled.
I'm not expecting any increase in MPG but given that i can use less throttle to hold the same speed and pick up ect who knows! before if the revs were under 1500 say, and i wanted to go from about 30-40mph and up i would find my self putting my foot down slowly and it would decide it needs to change gear, but now it knows the power is there so it doesn't change down and i don't need to put my foot down so much....


The thing is a beast but still perfectly mannered if you want!

Here's the site, they specialise in VW vans mainly but know there way around the BMW ECUs!
http://www.pendleperformance.com/index.php

Anyway, enough waffle, here is the dynos, as you can see, stock its meant to be 204bhp but it was 194bhp.


Before:



And After:



So to recap,
Before 194.5bhp 430.9nm
After 290.2bhp 577.8nm

WOW! Thats a big jump, nearly 100bhp just from re-mapping. You'll certainly notice the difference! The 325d is a 3.0 but detuned isn't it? The reason I ask is my mates looking at 525d's because they're more readily available with manual gearboxes but I keep telling him he'll be disappointed and wished he'd held out for a 530d. But..... If a re-map makes a 525 back into a 530 and then some it doesn't really matter

My 330d was already done when I bought it so didn't get the fun bit of the first time flooring it and feeling the difference. I haven't got a dyno printout but just a receipt that says 231 to 305. I was sceptical but seeing your results maybe it's true, I must get a power run booked to find out.......

[Andy198712]

Depend on the age of the 25d, only the later ones have the N57 engine, earlier models have the 2.5 so worth checking

The difference is night and day! Driving it today it lovely and smooth and drives like stock when you want it so, my mrs didn’t even notice it’s been mapped yet

All 2.5's are actually 3.0, even the M57. However whereas the N57 2.5 and 3.0 are actually identical engines but with different stock maps, the M57 differences between the 2.5 and 3.0 are down to different injectors and possibly other hardware (not owned one so not 100% on all the differences) as well as the map.

So in short, the M57 2.5 won't map the same as the N57 2.5 with regards to gains vs the 3.0 version.

Does that make sense?!

how much did that cost? it doesn't show any pricing on the site.

ive got an rr printout for mine at 305 bhp and 698 nm...and the 325d is identical in the later models as the 3.0d just the mapping is different,,thats how you get 100 bhp over stock,,as its really 231 bhp in theory

i friend has just brought a 2008 525d and its 2.5.... think it depends on when they changed that?

at the minute i think its about £350 plus vat, but watch this space as people are starting to develop OBD tuning for these cars and it is coming... which will make it cheaper.
i say about as we took two cars there so got a good deal.

worth having a chat with your chosen agent and seeing if you can knock a bit off

i even think the N57 330d is 245 stock... if i recall

Apologies, I thought the 2.5 M57 stopped with the E39 but it appears it was used in the E60 up to 2007. After that they are all 3.0 regardless of whether its a 25D or 30D.

I would guess your friends car was probably one of the last to be built with that engine with a build date of late 2007.

It is because that's what I have, apparently mapped to 330ish BHP but I need to RR it.

It does pull away (slightly) from a friends car which is pretty much identical but RR confirmed at 310BHP

depends on the torque and where in rev range its delivered..i love my e46(265) bhp as its so linear compared to my e90..but the e90 is fun,cannot wait to get some uniroyal tyres on it after the tyres thats on wear down,,will sell the fronts though as they still have 6mm but are crap

[nomiS330d]

It's the torque these things kick out thats so impressive. In the wet I was getting annoyed by the traction control light flickering through the first 3 gears so I spent a lot on an LSD to help with traction. These torquey 330 and 335d's need it IMO, especially when mapped! Drifting is now an absolute doddle, no clutch kicks necessary ;-)

i can spin up the wheels in third no problem in the dry,,i have a little drifty place near where i live,,i start spinning in first,,then quickly into 2nd the play with throttle/clutch and start turning with a little flick,then floor it but blipping/clutch play at same time then before all the torque fades away i put it in third and continue flooring/blipping..im trying to get rid of the bridgestones on the rear so it would be rude not to,,should of seen the clouds of rubber smoke the other day,,im surprised nobody phoned the fire engine ha ha wont be doing it when i put my uniroyals on though..having huge torque is just so fun..

before it was nicely matched to the handling and chassis, now i find i'm on the brakes a lot more before corners so may look into further upgrades as and when....
so you really noticed the LSD?
i think PS4 tyres will be after these Eagle F1s i just put on, which are great but....

such a evenly solid pull all along the rev range on this now, just roll into it at about 2k and watch the speed fly up!

funny thing is i can poodle around at small throttle openings and drive it like a normal car, then it just transforms

more torque then an M3!....

All that torque eh? Still sounds like a tractor

they don't sound the greatest that is true! sound pretty cool with certain exhaust setups mind! some of the audi V6 diesels do sound nice straight piped also....


the car sounds difference now post remap, before it would level at 18psi boost, not checked what its making yet but interested to see

Yeah, I did hold out for 15 posts though

A remapp does make a big difference & diesels do make big gains, caused mostly by burning more of satans fuel, so you enjoy your torquey oil burner & you can drive around with a big smile on your face with your cheap road tax & high mpgs & don't you worry yourself over all the poor little children with respiratory illness that you are contributing to

Glad you like your remapp, I still remember first driving mine after it was mapped

its like my first drive when i fitted my 2110cc engine into my 1200cc beetle, 34bhp to 150....
