Pretty much all the AT owners of the 335i had complaints about the AT software - even on my test drive it made some weird gear changes while driving - then someone tipped off someone in the US that inside the spdaten software ( i think its like the software all bmw shops use for diagnosing/writing for bmw cars) that this file was basically the alpina software to be used for the transmission basically got the info out of the forums from the US - might pay to troll through the forums in the US and see if this was ever done for your model

Ah bugger they changed the hardware It was just a software change on my model the alpina guys did - flash was soo much better then stock - sport and manual modes actually put a big smile back on my face "transmission run smoother, gear change will be more precise and crisp, rev match downshift is unbelievable, rev limiter is increased and overall driveability is increased. You will have a new indicator for gear selection in D mode which display D1, D2, D3 ,D4, D5 and in DS mode you will see S1, S2, S3, S4, S5 and the same for the M mode. This single flash will make the car change gears more refined and crisp. You will no longer feel the lurching when the tranny shifts and it goes through the gears without even the slightest hesitation"

Do you know if the alpina guys did a software change for their 540's? (TCU flash) I'm running the alpina TCU flash on my car - i just provided Gavin/Ross the flash file/link and had them do it for me - http://www.n54tech.com/forums/showthread.php?t=20991&highlight=alpina

WTB youtube vid is from my iphone 5 - not exactly stellar

Had the downpipes, exhaust, and KW V3 coilovers installed Will edit thread when i get the pics and dyno runs OFT Map1 @ 342HP Running logs from some 3rd-4gear runs and it looks like i'm leaking boost somewhere - back @bmworkshop on Monday for a smoke test to find the leak and get some runs done so i can get a new customised map for my setup before next Saturday dyno run

Hi With the height drop i would like to get out of my KW V3 coilovers , it looks like i would need to have my fenders rolled Am looking for a shop in auckland that's highly recommended to get this work done http://www.e90post.com/forums/showthread.php?t=814434 thanks

Pretty nice figures The BMW skidpan event on Friday was quite a bit of fun, quite interesting how much your DTC and DSC system does when you're trying to slide the backend out - keen to do it again

Nice catching up with you at BMworkshop Botany this morning, how did the dyno testing go?

Definitely will do , thanks Am keeping all my factory stuff in case down the road i sell the car and return it back to factory state

Yes, just the factory oil cooler ty was down there to see chris@autoquip about the KW V3 coilovers, hopefully getting them installed this week if they don't run out of time at bmworkshop

Which intercooler did you get? did you end up buying downpipes? i saw a thread where Cobb is doing a upgrade path - you can send your old cobb to them and pay a upgrade fee to get the V3 version Was at bmworkshop yesterday getting some new dyno baselines before the downpipes & exhaust were installed Current mods on: FMIC, Bov, OCC, DCI, 20inch wheels & tyres Run@factory map - 238HP....i was like..i lost HP - 253HP was the measure before then realized they with the new 20inch wheels, not the factory 19's when i did the initial baseline Run@OFT Map1 - 316HP - afr/boost/torque numbers looked good Will post the graphs once i get them emailed , will be interesting to see the dyno difference with catless downpipes/exhaust

Am using BP Ultimate 98 Ya, car's a lot of fun once running a tune When i looked for e85 options, the only place that is in auckland for e85(Gull Force Pro) is Gull Pukekohe Gull Force 10 is 95 + 10% ethanol from the datasheet, if i was going to run ethanol - imo would only do it if it was e85 and widely available in auckland due to your consumption is higher when running ethanol blends

From what i have read/seen - intakes could be up to maybe 15HP - BMS DCI's are like $110 US , other kits are like $500 US+ - cold air intake systems may be better option in a climate where its hot and humid

That car was so dam quick, it was making around 420-440HP when i was there last year, he is currently getting the e85 flex fuel conversion kit installed - seen on the forums people making over 530HP with similar setup's on e85 Didn't know you could get the large 02 bung ( wasn't a option when i ordered) - http://www.n54tuning.com/ was having a sale on the AR downpipes when i bought it ( doesn't look like they're having one now), another thread to watch for specials : http://www.e90post.com/forums/forumdisplay.php?f=204 Would be good to compare what dyno figures you're getting with Cobb - Ross was going to get my car dyno'd with the OFT Stage1 Map on my car (running FMIC, Bov, DCI), and then compare once the downpipes/exhaust are done

Ha ha, no probs - i was over in US last year and my cousin has a highly modded 335i - and after riding around in a modded 335i (AA intercooler, AA BOV, AR downpipes, AA exhaust,RB turbo's, Procede, Meth kit etc etc) - was pretty set to pick one up this year when i was replacing my e46. So basically chatting to my cousin about the mods he had done and reading forums ( pretty big n54 modding community in the states) e90post, Bimmerboost - i had a general list of items AR from what i read/reviews from a quality and fitment and i liked how you could optionally ceramic coat the pipes - plus the vendor i was getting my BMS products ordered from was having a sale on the AR - picked them up for $600 versus the normal $800+ they usually go for Have read the factory DV's have had issues(leaking, factory charge pipe's coming off, protect from compressor surge) once you start running higher boost on your turbo's and i like the sound of the Bov - The BMS oil catch can is highly recommended with the n54 engine - intake valves get coated/gunked up and lowers performance - if you look up on this thread, there is a picture of what my intake valves were looking like before i had them cleaned, the oil catch can is to stop that coating my intake valves

I always factored in the GST duty when i was buying the goods from overseas, but in reality it was really hit and miss with paying GST as bits were ordered from different vendors and shipped in over a period of 2 months eg when the intercooler and bov kit was shipped from Active Autowerk (over 2K US with shipping) it wasn't picked up and sailed through custom Exhaust, tyres - were picked up and paid duty it seems all the small packages didn't get picked up from my chat with Ross, the downpipes are quite tricky to install on the RHD models - haven't had them installed yet so can't give you a figure - and with the way the project is going - multiple items are getting done at the same time - best bet would be to call Ross and get a quote-was waiting on my wavetrack LSD and DEFIV Differential Lock-Down winging his way down and them all done at the same time, hopefully be here by the end of this week DEFIV Differential Lockdown Wavetrac LSD

KW V3's arrived this arvo, now to get them fitted

The n54 platform is quite interesting - what people are achieving with stock or FBO options an example: http://www.e90post.com/forums/showthread.php?t=880319

Good to know you're happy , ya i saw Chris@autoquip yesterday - his prices were def on par Ya im pretty much going to go with V3 - only thing i need to check if they fixed the squeaky sound issue - seems back in 2010/11 the V3's that were installed on the 335's - lots of people were complaining def want to drop the ride height a bit- LSD is right up there after the suspension -

thanks Neal, looks like some good info there to ponder

Hi Am looking to change my suspension to a coilover set - anyone put in KW V3 or ridden in a car with a set? Anyone had issues with KW coilover set? thanks

Ya, there's a few for the 335i, wavetrack, OS Giken - need to read some reviews etc

cheers, its getting there! The final bits arrived yesterday at BMWorkshop (exhaust etc) - car's booked in for Monday to get the final parts installed (downpipes, exhaust) and then Gavin@Hi-Velocity will get the car tuned - be interesting to see how much additional HP can be added, the Michelin from the limited testing i did, held up very well and my DTC wasn't coming on as much with the old wheels/tyres, but that's kind of the next part i am looking at is a LSD for the car

At minimum of 1/2 days worth of work and was quoted $500+GST, i believe so - will double check with Ross
