Unfortunately this is not a cheap/easy to solve. Also - i am assuming when you're at the track , you've reflashed and changed the MHD cooling option to race I would start backing off once i saw oil temp hit 140 at the track Oil and coolant temps go hand in hand , just upgrading the oil cooler to a bigger version might give you one or 2 more laps ER Oil Cooler BMW PPK kit retrofitted ( bigger fan / additional radiator etc) CSF Radiator BMS thermostat ( would recommended the Mosselman N54 Oil Thermostat instead) With the above mods and E50 map - was able to do a 15min track sessions without buttoning off. Was looking at doing a transmission cooler and upgraded turbos (stock ones are just full on heaters at this stage ^^ ) but with all the cooling upgrades on car...daily driving was kinda meh as it would take ages to get to temp before you could go WOT. I could leave the office near nelson street, jump onto the motorway...get off at manukau and its just got to temp / normal city driving would take a little bit longer to get to temp In retrospect now - I think WMI system would of helped alot ^^ how could you tell? j/king That was the big difference daily driving M135i , no freaking gauge like the 335i so i knew when it was warm enough to go WOT / had to use the MHD app before Having pure turbos stage 2 ....daily driving temp is 95-100 Did a track session the other week at hampton...think i saw the M135i oil temp got to 118 lol >.< 09_Cooling Systems.pdf

Finally decided to upgrade the turbos ^^

You can transfer XHP/MHD licenses from the previous owner if you contact their support Sweet so its setup to run ethanol maps , you'll realize how "slow"the 98 maps feel

Would totally agree with Steve on the OTS 98 map vs custom tune , no point with stock turbo's ....and if you're running E85 you definitely want a custom tune over the OTS maps Remember if you decide to install inlets/outlets with stock turbos , you will have issues with OTS maps and should get a custom tune I looked into remote tuning on a dyno but the costs were going to be silly.....done all my tunes via logging etc....not sure how you lose functionality??

Don't get the CEL lights with the appropriate stage2+ map on MHD , its deactivates the check on the map from memory

Have had aftermarket downpipes on mine for over 4 years -no issues getting a WOF.... I'd look at the VRSF ones as its reasonably priced

Hey John I have the wavetrack installed on mine and another friends e90 335i-, works really well on road and track and is a must option when running some serious power Another friend of mine had the M factory diff installed on his 135 and it unfortunately screwed his whole diff as the pins in the unit popped out and munched things Was one of the units apparently under recall due to a factory issue with the unit bolts not being secure - I will give M factory its dues that it stepped up and sent a new diff and paid for all the work required to fix / sort the issue btw - if you get a LSD i would suggest a few of the re-codes as below http://www.onelapx1.com/blog/how-to-make-your-bmw-actually-fun

Interesting take about the E46 vs the E9X models John I came from a E46 325 before I got the 335i , tho my E46 was pretty much just standard so for me the experience was a big upgrade going to the 335i The stock suspension / runflat tires on the 335i is pretty weak imo , scared myself a few times when I was running a tune/upgraded power and a trackday at hampton showed me the glaring weakness of the setup , its probably a fine setup at stock power levels WIth the M3 suspension parts fitted (all apart from the rear M3 sway bar) with KW coilovers, LSD and sticky PSS , I think it handles well now for the power level its at It sucks with the model/year of your 335i john that your auto transmission doesn't support the transmission flash (XHP or Alpina) , to me that was a another big upgrade Also when you run a ethanol map on the car, you'll notice how different the car is , that TQ life These engines are surprisingly strong , quite a few people in the USA have been running 600RWHP+ (with single or upgraded twins) on the stock engine The take from the community is that above 650+RWHP on stock block is when it will go at some stage I've nearly put on 100,000km from my 4 years ownership of the car in my rear mirror ?

I have heard of Prestigio - from memory you had to be in the "prestige group" when running with playday group and you could get insurance for the day at the track

MT option

Yes you can go from Alpina > XHP there is a bug if the alpina flash wasn't done correctly on the TCU (https://bmw.spoolstreet.com/threads/xhp-flashtool-official-beta-results-thread-for-6hp21.1483/page-8#post-11373) With the tune on your car , I would suggest flashing back to stock map via the cobb and then doing MHD (my 2cents)

The MHD OTS maps imo are conservative - you'll be fine with the stage1 98 map , but as always when you change stuff up , just log for awhile and confirm everything is looking right Ya that sucks about the earlier 06/07 models not being able to use the Alpina flash - if you can get this TCU flash , it will be such a huge difference as the stock one is soo laggy imo XHP is the new option for the auto guys , not sure what the deal is with the earlier years (06/07) - you can download the app on the device you're using for MHD app - connect up to the car , run the app and connect - will show what maps/options are available

Fair enough I switched over from the Alpina flash to the XHP stage3 map over the weekend - D&S mode are a big improvement over the Alpina version and M mode is faster with upshifts and downshifts but I don't think I have done the 100km driving range for the transmission to fully adapt yet Loving how M mode won't upshift at redline now , makes things easier

Would also recommend you just run the Stage1 map with your current mods initially - What trans have you got John in your 335i? Same with N54 , stage2 are recommend with downpipes I wouldn't be keen putting anything less then 98 on a modded n54/n55

Did the night drag wars the other month for the first time in the 335i Only did like 4 passes as it got really busy down there, 4th attempt took 1/2hr to que

Quite a difference eh steve on E40 vs 98 maps, just wait till you run the E60 OTS/custom map - that TQ curve I got the kit a few months ago from Fuel -IT as well , pretty bummed out the new flex fuel system on the MHD side uses another ethanol sensor - apparently the fuel-it won't work with the kit Just bear in mind on the 335i - you can run 30/40 mix with the stock LPFP (low pressure fuel pump) - if you want to run more on the stock turbos/upgraded turbos , you will need to get at least a stage2 LPFP from Fuel-it

Very nice build Which generation of the RB turbo's? are they the new RB evo versions? Interested to know which kit you'll get for port injection - I see there are quite a few vendors doing the new intake manifold with port injection ports built in etc

Hey Julian, I would get the MHD over the cobb for the same purpose you are looking for Haven't looked at what pricing of the cobbs are - last time i looked they were around 800-1000 US for a cobb verus how much for MHD (depends whether you have android device already etc) Ya - I was running the BMS flash stacked with the JB4 - but now with MHD - no point running stacked mode with stock turbos unless I was running hybrid/single turbo upgrades MHD is very easy to setup with your car - more then happy to show you a demo if you're in auckland

Cobb is obsolete , they stopped development on the n54 platform a few years ago - I have switched over to the MHD and it's pretty easy and being able to get a Protune was a big factor for me changing from the jb4 Sent from my iPhone using Tapatalk

I use the southern motorway past Dury around 2am+ ....... I have been running 400rwhp+ for over 2 years on my transmission (car was 253rwhp on factory tune) without any issues only thing I have done is change the lifetime AT transmission fluids when I got my car to FBO and running the Alpina flash (which up's line pressure etc)

Quote "ZB # are incremental, and larger numbers are the newer files. 7615835 is the last Alpina B3s transmission FLASH that was released and has a direct impact on torque limiters. The Alpina FLASH is listed as an E90 N54B30ATL ECE FLASH and was released in 2010. It is the most recent N54 AT specific transmission FLASH that has been released for the GS19.11.0 transmission, again this is specific to the N54. All of the 760xxxx files were done in 2009. There are two older FLASHES you can try. 7603537 and 7603535... Both are E90 N54B30ATL ECE FLASHES. 7603527 is a FLASH for the E82 N54B30ATL and release in 2009, so I'm not sure how anyone made the assumption it was a 2011 sport flash. 7603541 is from an E89 N52B30OL. Not even an N54 transmission flash. 7601494 is also an E89 N52B30OL. Still not an N54 transmission flash. There are a lot of GKE215 ZB#'s you can play with. Not all were designed for making the power our cars make. I have to laugh when people without any knowledge of what they are talking about release old ZB#s as newer numbers as if they found something new. Depending on the power you are making, chances are you'll have torque limiters in higher gears or your clutch pack will slip because the line pressure isn't high enough"

It's between the Pure turbos and Hexxon turbo's - i'm personally leaning towards the Pure offering http://www.pureturbos.com/store/bmw-n54-pure-stage-2.html http://www.hexonautowerks.com/products_detail_36.htm?pg=&PdSearch= Am around 400 RWHP at the moment on stock turbo's - been pretty happy at that power level, but it's been 2 years and I'm getting a little bored and want to get some more , with the above turbo's - should be around 500-550 rwhp on 98 and 600+ rwhp on E85

Am going to remove my JB4 and switch my tune to the MHD app and getting a Protune for a E50+ map from Motiv Will re-install the JB4 and use it in conjunction with the MHD when I do the upgraded turbos Found a good article on some settings , and have coded the following out: http://www.onelapx1.com/blog/how-to-make-your-bmw-actually-fun Engine Power Reduction to Prevent Brake Disc Overheating (FLR) Brake Fading Compensation (HPS) Electronic Differential (AX_Ref_Diff_Lock) Will see how it goes on the track , the last one is really the one I am interested to see how it feels like as I have always thought something was interfering even when sitting with DTC / or totally off

Sounds like something is broken if the car is setup for E85 but performs like crap (I assume that the holden has all the those attributes you mentioned - fuel lines/ flex sensor/ecu mapping etc) I have to calculate my blend , plug my laptop in and flash my ethanol map backend on the car - run some resets (octane reset , afr reset) then I'm good to go - so quite manual when I change fuels I saw a 45-50hp gain / 80nm TQ on the dyno on E60 blend tune vs my 98 tune, I love running ethanol and if it was at more service stations, I would run it full time tbh

saw this multiple times over the xmas/new years period when travelling around..... cop sitting on the other side just as the passing lane came into effect.....thankfully my radar detector picked them up! revenue gathering at it's finest!
