I wouldn't risk my box for a quicker shift

I see your point but I dont see what the risk is... Surely no more than risking an engine on a remap?
Also, JF Tuning and JR Automotive DO advertise the gearbox remap.

Did BW remap your gearbox or your engine map?

I never said they didn't I mentioned the place by me don't advertise it or so they didn't...

I don't know for sure but if the remaps of the boxes take the figures beyond manufacturer recommendation then I see a risk

[Jim1985]

Fair enough.

Something I am considering too Jim, it never quite seems to do what I want it to do and in 'M' mode there is too much of a delay between me flicking the selector and it actually deciding to change gear, which is annoying.

I have a love/hate relationship with it, perfect for the daily commute, not great if you want a spirited drive...

Mine only drops down on it's own when the revs get to around 1,000rpm, it needs to change down at this point

Would a gearbox software update not help at all?
Car would be so much better to drive if the torque converter to locked up earlier on

Yeah, very knowledgable and charged me £330 which included the gearbox oil sleeve which had been weeping oil.

The tech took the car for a drive first, came back and said it had clutch slip (clutch slip in a torque converter??) in 1 -> 2 and 2 -> 3.

When they took the pan off, they did say it was a little low. They replaced the oil and changed the sleeve in just under 2 hours.

On the way home, it did feel smoother.

Now I just need someone to reset the adaptations for me....anyone care to help?

Jim1985, you need to look at the facts:

• Approx 300 for a engine remap, guaranteed results;
• Lots of companies offer engine remaps so it's tried and tested;
• Approx 400 for a gearbox tune, sketchy results (read other people's experiences);
• Only 2 companies in the UK actively offer it, so not as much experience in the field;
• A gearbox specialist advised against doing it;
• One company in the Midlands (the one Raj has mentioned) used to do it.....When I called them, they said they COULD do it but don't recommend it; One customer had it done and was back within a few days with a completely shredded transmission. They did say he wanted a faster shifts and earlier lock up than what their tune gave him. They did warn him but he was adamant - They stopped advertising it after that.

Make of that what you will....

Don't get me wrong, I was just as eager as you are when I first heard about JR and JF - in fact, if you look at my profile, you will see that I started a thread about it a few months ago.

The only thing I am still curious about is how the Alpina flash works for the 335i and not the 335D. Is it because the Alpina flash is only applicable for the DCT gearboxes?

[Jim1985]

It doesn't look good does it!
I just want the lose the slop! Looks like it'll be a sprint booster after Xmas then!

I can do the adaptations for you in INPA or you can do it yourself

[IceMan007]

Have you tried resetting the throttle adaptations? Very easy to do:

1 - Get in the car, put the key in the slot and press the start button (making sure foot is OFF the brake so the car doesn't start). Instrumenation should come on;

2 - Fully depress the accelerator for 1 min. Don't take your foot off the accelerator and don't touch anything else in the car;

3 - Without releasing the accelerator, press the Start button, switching the instrumentation off;

4 - Release accelerator pedal and leave for one min. Don't touch anything in the car.

5 - Start the car and drive as normal and you should notice the throttle being more sensitive as the adaptations have now been reset to default.

Nice little "get you home" until you get your sprint booster.

How can I do it myself? (no s/ware nor cable)

Thats amazing thank you! I'll try that tonight. I feel I may be constantly confusing the car with my spending most of the week commuting at less than 30mph through town, and driving at 60-70mph on the motorway sedately, and then juxtaposing this against a manic weekend blast using every last possible single horsepower at my disposal.

Will it simply be constantly adapting from one extreme to the other?

It's constantly adapting and will adapt based upon majority of throttle pressure since last reset. You say most of yours is light throttle?

Do the reset - and report back

[Jim1985]

Will do!

[IceMan007]

Raj, is the procedure I've described essentially what you're offering to do, via INPA?

If so, I'm more interested in the gearbox adaptation reset rather than throttle position.

[mob17]

Guys in the States should have some data soon to see if the gearbox remaps offered by JR and co actually does anything

it does make a difference and you can tell. i have been in a 335d and it was lethal as it had a map on it aswell but his box started playing up and when he used to upshift when hes hooning it it will rev up to the red line and then upshift

Well I did this...

Wow!

This has made so much difference to how it drives. It feels like a new car. Very impressed. Thank you very much for this tip.

I strongly recommend that anyone with an auto do this NOW!

Interesting; If I'm "hooning", my gearbox will go all the way to the redline and then upshift but my transmission has NOT been mapped!
