I got the M335d. Not sure at the moment. I need to speak to Sal or one of the guys while I am there and make my mind up.

I don't want to comprmise anything, neither do I want limp mode.

Most my driving is done on motorway between 70-80MPH.

At the moment I feel the car is very sluggish from standstill, so would like some extra torque low down. Was looking at your map and that seems like a real nice all rounder, so might go for that.

I am sure that SAL will be along shortly but Evolve have at least 3 maps on offer, you'll be more than happy with the map I have, the middle map is the best compromise of all of them as it offers low down torque in line with a normal remap and good high end power. You'll be happy regardless.

You wont get limp buddy. Im thinking you would need 370bhp + for that.

I have 345ish currently with no issues not even on track with limp. I have experianced it before on another map, but the car was SIGNIFICANTLY faster than its current 345ish. SO i guestimate 370+ when it happened.

Carlos, can you describe what limp mode was like please, did the car just all of a sudden feel lethargic, e.g. it would still accelerate across the whole rev range but nowhere near as fast as before?

It never happened when i was at full pelt. Once backed off and i went to re-apply full throttle the car would rev, very slowly and accelerate like a metro. Happened 4 times to me in the space of one evening. I dont think it rev'd as high as 5k either.

Had to pull over. Turn car off and on again to clear it. Otherwise the car was going VERY WELL. Faster than ever before. Drove home 150miles with out issue.

But you had the map removed and replaced?

I've experienced exactly what you had whilst at one of the Vmax events, I must admit though that I thought it was more likely to be heat soak.

Jules.

No it deffo is limp home, although heat soak i presume could cause limp home mode. But not sure how you would get heat soak doing top speed runs?

I had the file tweaked and the car seemed less powerful but still made 344bhp

I have not had it since, Including my trip to Bruntingthorpe and a Tack day at Snetterton.

Im happy now, Sal did his bit of magic on the car. Only managed to get 320'ish bhp, but the car feels transformed. I think the low power is something to do with the fuel, so going to have to wait till this tank is empty. After filling up yesterday and adding some cetane aditive I noticed the MPG was down, but put it down to the car readapting, as it just came back from BMW, and they did a full progman and ECU update.

Will monitor and see if it improves after the next tank, which won't take long while using all the extra torque available now

Wouldn't worry too much about the figures recorded, just enjoy the "new" car....
Jules.

ps only worth using the additive if you have to use crap std diesel.

after reading this thread as a link on Audi sport forum I just had to give Sal a call, I've decided to go with variant 2 which offers 350bhp and 700nm of torque to avoid any traction issues.

The cars only done 800 miles after 3 weeks of ownership and already feels fast even in comparison to my previous 8p S3 which was remapped by GIAC so I can only imagine how good it will be after the evolve map

Jules mentioned a map which had less torque and more BHP. That gives almost identical torque to his origional map (still boosts eariler) and makes a minimum of 15-20bhp above his origional once over 3500rpm.
This map will be going on an E90 post members car later this month.

With some help of the E90post members (especially Jules) we have had the chance to have a few 335d's on the dyno and have 3 different types of main maps:

1) 330 bhp / 650 Nm
2) 355 bhp / 700 Nm
3) 340 bhp / 730 Nm (<< Jules Map)

We can create more variations but this should cover most people's needs.

Just to point out, there are loads of 730Nm mapped cars over in Germany and Italy which have been running faultlessly for many thousands of miles and driven very hard.

Noob question.

From my reading, there is a marked difference between these 3 maps....

But in what circumstances would you choose each map and why?

I'm just trying to figure out which type of map would suit me and my real world driving. I'm not likely to do a 1/4 mile or high top speed ( I've never taken any of my cars abroad)

And do Evolve replace a dealer wiped remap FOC?

Map 1 would be the most sensible option.

I have the third varient which is very, very torquey, don't get me wrong all of the others are and compared to standard (which is also impressive) it is a big leap forward.

Map 1 will give you all the performance you need, the other two are a step on again but as with all remaps something will be compromised such as mpg, which again compared to standard Map 1 will offer better mpg, Map 2 & 3 won't be quite as good, but still my car is averaging 38mpg.

Cheers Jules - good info

[Spin]

I went for map 2 and the car achieved 350bhp on the day up from 288bhp as standard.

I went for this map based on advice from Sal at Evolve after explaining my requirements, I do mainly short journeys but this will increase when the car is transferred over to my wife in 12/18months time, I wanted reliability, nil smoke and a bit more power than offered by the main competitors so the 330 map was out for me. I don't plan any drag races so Jules map was moved to 2nd place but have to admit I'd love to give it a try

The car drives absolutely as standard until you let it have a bit more right foot then responsiveness has dramatically increased along with a massive grin inducing dose of torque, amazing value for money IMO. Its too soon for me to judge the mpg differences at the moment but I'll post an update in a few weeks.

Evolve = great service

One question I haven't really seen asked/answered, but how do these maps effect the "learning" ability of the engine/gearbox software ?

In normal use exactly what paramters are passed to these learning routines, and by altering the power output/delivery are these increased values passed directly to the learning routines (which might not be expecting these increased values) ?

They dont affect it in any way mate.

Ive only ever noticed a difference after a trackday. I was flat out for 75miles and the car was very responsive on the way home. Its back to normal now which for me is driving very hard but in no way comparable to driving flat out on track. Thats the only time ive noticed any difference in the adaptation of the gearbox.

No offence, Carl ... but I'd like the feedback from those who actually know. Not guessing and subjective feedback.

what? So i dont know but others who have mapped their car do know. How will they know more than me then?

I suspect you need to speak to a BMW gearbox engineer buddy...

Dave, hell of a set of questions you've posted there and in all honesty I haven't the answers but you have got the 'old grey matter' stirring. My gearbox did appear to re-learn post re-map but was this down to the fact that I altered my driving style ie. trying it out (which I did), or did this occur because of the increased power output of the engine. If the latter is applicable then that could imply that the learning routines are linked ie. the software 'communicates' between engine and gearbox.

My rather basic understanding of the re-map Simon did on my 335d was that it was the engine that was re-mapped, not the gearbox. I am assuming that the re-map is done within the safety parameters of what both the engine and gearbox will withstand. When the car is driven hard for prolonged periods and goes into limp mode, is this the gearbox that is saying 'hang on a minute, I need to cool down'. If so does this then imply that the learning routines of the increased values are passed to the gearbox as well thus triggering the limp mode effect. This could also imply that the increased values are passed directly to the learning routines.

There will be someone who knows for sure but I suspect it is more than likely to be a long standing professional re-mapper/BMW expert in Germany itself.

Food for thought though.

i have a 09 plate 335d which im looking to map this weekend with a dpf and egr delete, dpf will be gutted rather than a downpipe,
the mapper's giving me a evolve 370bhp 680nm stage 2 map, im not sure if he has the figures correct though, as i thought the torque should of be around the 730nm mark for a stage 2.

Originally i was gonna stick with a bluefin map, as ive had one previously on my 07 335d, and still have the dongle thing, bluefin would of charged me £225 to upgrade to a different car as all dongles are uniquely registered to chasis numbers, how ever bluefin dont support egr and dpf delete, i did seek the roots of hacking the bluefin dongle, but failed with no joy :-{ Bluefin remap for the 335d perfomance wise the power delivery was pretty awesome, it was super rapid than box standard. I had plans for a remap later on next year when its abit more dryer up north, but last week my dpf clogged its self to death, causing the engine to cut out when ever i went out in it.

Ive read a few reviews on evolve maps, so far everyones said pretty decent stuff about it, and supposingly its pretty bad ass quick, i personally used to s**t myself with the bluefin 340bhp 680nm map when driven really hard, my heart was always pouncing on my tongue and i'd sweat bucket loads as adrenalin pumps through my vains lol, one thing i made sure, was never to take my eyes of the road and never take my hands of the steering wheel. Any advice will be much appreciated on if i should service the tranny as the cars covered 70k, also will the tranny need to be reset to factory, ive heard theres maps for the tranny torque converter too, not sure if im correct, also with a stage 2 map, i know i will have go down the routes of bigger brakes, but will a bigger intercooler be neccessary.


thanks

For those who are nervous at the thought of putting +700Nm through the standard box here is my experience.

I've been running 817Nm (and 417bhp) for the last 35000miles. Car has now just hit 100000miles and there are no ill effects. Gearbox was serviced at 57000 and 81000miles. Planning on doing another service at 110000miles.
