That doesn't sound good, but I may be able to help you with that. I flashed about 20 transmissions, it also went wrong on a DCT once, but I was able to recover it.

Can you please write down exactly the steps you did?

Did you hook up a battery supply (not charger!) with at least 10-20 amps?

Followed these steps
http://www.n54tech.com/forums/showpo...9&postcount=25 and tried to flash 8606072

but as soon as I started flashing the cic said cannot put transmission in p...I let it do its thing
The flash progressed once very fast, then once very slowly. Got to 100% and some errors popped up.
Error 209 UIF cannot be read
Tried to flash again and errors came up this time they said ecu disturbed, that time I had it hooked up to my mates car with some jumper leads
I may not have set the computer up correctly and that may be part of the problem but you would think that if it was set properly that it'd fail straight away ?..

Everything sounds good/normal, except the "Error 209 UIF cannot be read". I'm pretty sure it was because you flashed without power supply, that was the reason for me too.

If you want, I can look over it through TeamViewer with laptop attached to the car, just hit me a PM. Just make sure you have good power source (car on jumper leads is also fine).

EDIT: Did you check for latency = 1 ms in com-port settings?

You shouldn't need a power supply or a jump if you have a decent battery. The flash should take no longer than a MHD flash, 2-2.5 minutes. Here's a pic of my WinKFP configuration settings, see if yours match. And like iCstyle said, make sure you have a solid connection between the car and laptop. Try INPA and see if you can pull up your info.

So I'm back on the road!
The faster baud rate setting wasn't ticked was the only difference. But I tried once I did that and it didn't work.
What seemed to work was going into control panel device manager, ports, right click the com port mine was 1 then click advanced and changed " selective suspend idle timeout" from 5 seconds to max which is 3600
I also changed my power settings on my laptop to never sleeping as well.
I also didn't move the laptop whilst doing it as microphonics might play a part in adding noise and therefore errors to the data stream.
I also recommend that you don't do things like this in a hurry. It helped to know that I had a day where I could work through problems and not have to urgently pick someone up...

iCstyle I couldn't find latency anywhere but if you could post up where it might be useful for someone else ?
And thanks to you and LMB335is for your help...


First impressions are that the car definitely shifts in a different way. I haven't cleared adaptations and I haven't tried a launch. I used the 135is

[Aus335iguy]

Should also mention that the latency setting seems to revert after disconnecting or rebooting as well.
also the flash takes about two minutes
I hope this helps someone else!

Keen to hear if your lc now works.

I'm keen too! The misses, not so much?

[MJ80.]

Hahah make it happen brother, the world is waiting. (me)

[Aus335iguy]

I still haven't had a chance to try the LC. The car definitely drives better in traffic though. It's lost a bit of the lagginess off the mark but still doesn't drive like an auto.... I'll try the LC maybe tomorrow if I can make an opportunity..

It will work 100%

[Aus335iguy]

Well it didn't work i tried multiple times and followed all the guides ... The car was warmed up as it had been sitting in traffic but may not have gotten the gearbox up to temp so maybe thats it ?
Ill try again when i know that its warm and also the distance travelled from cold start to attempt was likely less than 10kms which from what I've read might be the minimum...

Ill let you know what happens but its raining here and I'm not keen on it right now

[MJ80.]

I dont even know if that temp stuff is legit heaps of guys reckon it will always launch without going 10kms.

Devoed to hear it hasnt worked...

Dont know what to tell you... might try the 335is update and see if that brings it ?

[maddmatth]

I think it's mainly based on distance traveled since startup, not temp.

Used my LC more times than I can count. It's refused to let me launch a few times even though car was at operating temp, because I had stopped recently and the engine had been turned off and on again.

There are probably some other parameters that will block you from using it though, temps outside a certain range, fault codes ect.

I don't think you necessarily need the 335is flash, just update it to the latest version. I have an N55 with DCT, has the latest TCU software as pere what the dealer would flassh, and LC works for me.
N54 versions might have different TCU software though? Might be calibrated differently for that engine?

Can you check which software version you're on by chance ?

[iCstyle]

Yes please check your old software. I was on 8606090 and I know that LC won't work on that.

BTW: Try to delete error codes with MHD (clear other modules), it could be that after flashing there are still some errors saved which prevent from LC activating.

[Aus335iguy]

Success !!!

[Aus335iguy]

It worked !!

[Aus335iguy]

So, to engage LC you have to think like a German ...
Ze car must be in goot shape first ya!

Car topped up with fuel, first time I tried I was on on reserve ...
Reset throttle adaptations, cleared codes, temp ok. The whole thing about driving x kms is wrong as I could get it work less than 200 m from starting it. Little bit of wheel spin but It does take off!


It is super addictive.

[iCstyle]

So you went for 135is software now?

[MJ80.]

Fuck yeah cunt.

So what sort of power/stage are you at ? What sort of rubber ? And how effective is the launch at 3500rpm ? Im still on the fence for that or the 5k.
