Thanks :)

Looks like it's on stilts in that photo, but it's still riding high after being jacked up at both ends. I've also ordered some cheap and cheerful center caps which will make things look a bit better.

Completed the clown shoes delete - that breaker bar made short work of the remaining stuck bolts, most useful £13 I ever spent possibly.

Car is now looking.... normal :rofl:

Well, I held out longer than I thought I would - but got impatient so started the process earlier in the week of swapping plates/insurance over from the E85, finishing today with taxing the E89. First proper drive this afternoon around Cheddar Gorge, lucky with the weather and a lovely roof down blast.

And another point to drive some debate :)

When I test drove this car, I was surprised at just how quick it felt. I know the N52 engine is 30bhp healthier than the M54 I'm used to, but performance stats/heresay suggest the added weight of the E89 means it generally feels no quicker than a pre-facelift E85 (and less quick than a N52 equipped post facelift E85 SI)

Today's first proper drive proved the point - it seems to be far stronger than the E85 it has replaced.

The food for thought bit: whilst Facebook stalking the previous owner (not sure if he's on these forums or not) I came upon the following post about my car:
Remap.png
Remap.png (309.68 KiB) Viewed 1762 times
Nothing in the service history to support this and only a rolling road would give any indication - but interesting none the less. I've long since ignored n/a tuning as being largely pointless, for mainstream models anyway, but I'm not sure what would be possible from this motor given port/polish/remap etc.

10/15 bhp at a guess? Ports are highly efficient these days so doubt there’s much ground to be made there.
Some of the apparent oomph maybe because your m54 had the original vanos seals (unless you had them changed)
They’re supposed to be in decline from 40k miles and this reduces bhp :?

Could well be Rob - never changed the vanos seals in my ownership.

45bhp increase from standard in a n/a car seems way, way optimistic and would cost a bucket load of money to achieve. My E89 is an auto too, possibly the difference in drive to my manual E85 is throwing my bum dyno out. I did have the heated seats on and they're damn fierce - maybe I scorched something :?

305hp is possible I think, but it needs to rev well past over 7k. They say mapping. headers + exhaust and milvs can be maybe +280 mark. Headwork should ad more, but you have to add revs and you will lose bottom torque.

Not know how, but 8200rpm they claim. [youtube]https://www.youtube.com/watch?v=Nwx50j1e9XI[/youtube]



Also https://www.1addicts.com/forums/showthr ... ?p=9529112 330bhp, but not stock ecu, ITB, headwork, cams etc etc. And of course quite experimental race engine. Limit might be near on this.


From this post above how they got 299 mark "To get the power we first removed all the standard wiring looms, ECU's, fused boxes etc and fitted a custom loom with Motec M800 ECU and Motec PDM 30.

ARP con rod bolts, E36 throttle bodies on custom inlet manifold, race headers as used by BMW South Africa and a lightened flywheel.

This gave 299bhp at 7200rpm."

If we look at this, tune, milvs, headers and headwork with maybe bit optimistic dyno, might get to 300 mark. Easy... no, cheap... no, possible... yes.

Thanks :thumbsup: trying to keep to minimal spend on this one as I went a bit nuts on the E85. Normal alloys, new (fake!) center caps and replacement front grilles is pretty much all it has taken but I'm please with how it looks now.

Thanks for sharing - interesting reading. I think we can conclude it's very likely my car has NOT had that much work thrown at it :driving:

Probably the last owner had it remapped and they must have told him he would gain 20 or 30 BHP more but in reality a remap on a NA would just make it drive better by eliminating throttle lag etc hence making it feel quicker, maybe? I haven't driven an E85 so can't compare but my 30i certainly isn't lacking. Your car is now looking great by the way. :thumbsup:

Thank you :) just going to enjoy it for a while now I finally have it insured and on the road (cruise control aside, which is sitting in the garage waiting to fit) but I'm sure I'll be thinking about a few mods sooner rather than later.

Actually I suppose a remap may add a bit more power to an N52 E89 than an E86, seeing as the E89 got a 255 bhp version of the engine but the E86 got a 261 bhp version. According to Wiki there was a 268 bhp version as well that was used for the E92/3, X3 and X5.

I imagine the only difference between the three is the mapping.

Anyway OP, your car is certainly looking better now. :thumbsup:

Well, this weekend was an experience :D

Cruise control fitting time, started out all confident - managed to get hold of the parts below for £55 off Ebay, which is very reasonable seeing as just the cruise control stalk alone goes for around £80 for the E85.

Basically followed Dave's (AnubisZed) excellent guide/video on these very forums (here) - but hit a good number of snags along the way. With hindsight, I don't think Dave charges too much for the full install including parts so for the grief I pretty much caused myself I wish I'd booked in with him to sort it for me. Good excuse for a drive too.

So, stuck at the first hurdle - couldn't remove the airbag. Not obvious from Dave's video, but when clicking off both sides of the airbag your screwdriver needs to be almost facing straight up - after finding another video on YouTube (this one - first 60 seconds is all you need) I had it off without issue.

Got the new stalks swapped over and everything reassembled (getting the steering cowl back together is tricky and I managed to cut myself on the plastic a couple of times), only to find my airbag didn't fit - grrr. The connector on the new stalks is very slightly different: (I think I was just unlucky here, as checking Ebay again all of the pictures show parts that are identical to the one that I took off my car)

This had be instantly worried that I'd managed to buy the wrong part :cry: but I took everything back apart, swapped over the slip ring from my original part, finished reassembling everything and powered up the car. I received the expected warnings as the new codings hadn't been applied yet, but also an airbag warning light and the horn had stopped working. This made me even more positive that I'd got hold of an incompatible part.

Ploughing on, I grabbed the laptop I've had up and running and have performed several codings on my E85 successfully, ready to code the E89.

Going through all the issues I then faced in the next few hours would be really boring, so here's some handy tips for other coding relative newbies:

1) My K+DCAN cable needed an additional adapter to work on my E85 (I believe something to do with bridging 2 of the pins to be compatible with earlier cars - some cables have a switch to bridge/unbridge). I initially used the same adapter in the E89 and had a confirmed power/ignition connection showing in INPA - but was then unable to read anything from the car. Trial and error (i.e. ditching the adapter) then brought success and I was able to read the ECUs.

2) Dave's guide will walk you through several steps to get the software up and running with required files. The MEGA link to the daten files is has now been removed, so you'll need to search around for an alternative. You also need to use 'BMW coding tool' to update the daten files used - I received an error when using this initially, complaining about the file 'MSCOMCTL.OCX'. The answer is here if you get the same issue.

3) My car already had the 'updated' value set in the first coding step - which I still don't fully understand. Specifically, my value of ‘TEMPOMAT_SETZ_ANZ_DAUER' was already set to 'wert_02'.

4) Dave uses the NCSExpert profile called 'Expertmodus (offen)' in his video when actually writing new codings to the car (this is the 'manipulation' profile) - but even though the 'pfl' file is called this, the settings for the profile mean it shows up in NCSExpert as something completely different (something like 'FSW-PSW MAN') which I now understand, but had me stumped for a while.

5) I then received errors when actually trying to write the new codings - exactly the same error as described here and also the same fix - after changing the latency of the serial port on my laptop to 1 (it was set at 16) the coding errors went away and I completed the guide successfully.

Took the car round the block, cruise control working perfectly - result.

I then thought it would be worth popping the wheel off again just to double check all was well visually with the airbag - sure enough, I found one of the connectors underneath the slip ring was just hanging there, so I must have not pushed it fully home when reconnecting everything up. Schoolboy error.

Now I had a working horn again :D but the airbag light was still showing. I've had to clear many airbag lights on my E85 using INPA, but as the only chassis option available is E90 all the module codes are different, so it's a non starter. I was pleasantly surprised to find that Carly will happily clear an airbag light however on the E89, as this is 100% not possible on the E85.

So finally, after lots of head scratching, panicking that I'd coded something incorrectly and resigning myself to booking in with Dave to sort all my problems out - everything is now working.

What a disaster.

Huge thanks to Dave though. By the time I'd actually figured out everything I needed to figure out, I simply followed the Youtube video completely to complete the coding and would have been lost without it.

Hats off for completing all that programming malarkey, I’m also impressed that Carly managed to clear the airbag light as I’ve read several times that it isn’t capable of this :thumbsup:

Changed the salmon red roof relays today.

No real reason, other than seeing it mentioned in a few places as a sensible preventative maintenence task - and at £24 it's a no brainer.

These are the 2 that came out - the whole area is clean and dry so no concerns, visually at least.
