Throttle response LC

[Wudee]

I have now done 500mls on my 2015 gsa lc and still have to get used to the throttle response. On my twin cam I could exactly control it the way I wanted but the elctronics of the lc making it difficult. I heard somewhere when you open the throttle the computer fully opens the bodies and then reduces it slowly to match with what power you need. This gives me a feeling of smothering(?) the engine and does not pick up the way I want it to. Can this be solved
With a pipe or reprogram? Also heard that for that reason tire wear is worse on the lc as it always gets full load for a second before trailing off.

Thoughts welcome

Whilst I agree the fly by wire throttle takes a little getting used to initially I have no such concerns and power delivery is smoothe and instant
As for tyre wear I never try to get more than 5 K from a rear but there are many on here that double that figure
A return to the dealers perhaps ?

The throttle response on mine is instant, so it does try to wheelie constantly in the first couple of gears - I leave it in Dynamic mode all the time, otherwise the traction control is too obtrusive

Welcome to the BMW shitty fuelling club, get your wallet out and enjoy the ride.
The awkwardness is the blend of light weight instant throttle response and very poor lean fuelling.
Look at the current Hilltop threads and see the dyno readouts you will see that at lower rpm speed there are places at which you give the bike 1/8" throttle and you gain 15 hp and other places where it will drop by 10hp hence odd throttle response.

No problems with mine, just got back from a long trip to scotland and it was a joy to ride. As above dealers, maybe try a demo for comparison.

I had the twin cam before. There is nothing that has made me think the bike is smothering the power, its a complete livewire by comparison.

I mentioned this at the running in service and they reloaded the software. No fault messages and no real change. Tire for me was about 7/8k MPs on tc riding half the time solo and half the time with luggage. And I don't really hang about.

Had a go on another clients gsa with 8k mls on the clock and a end pipe. Felt better, but still a little hesitant at 3500/4000 revs. Dynamic is better I agree.
Don,t want to jeopardise the warranty with a remap really.

 

[RedRick Esq.]

I have had mine re mapped and it got rid of the horrendous flat spot that you mention at 3-3.5 I believe the re map is worth it as it actually makes the bike fuel as BMW would have liked it but for the emissions regs as for warranty Geoff assures us all that without sending the ECU away for very expensive analysis it can't be found

This is NOT the case on BMW cars.

If a remap has been done the simple plug in diagnostics will show your bike as having a 'Modified Engine' and any attempt to make a claim for engine/drivetrain issues will be refused.

Geoff has said time and again about the visibility/or not of his work.
Many people have said not possible.
We have yet to hear of anyone having their Geoff remap causing warranty issues.

 

[Skid06]

if your a type of guy who lays awake at night thinking a sticker might be a modification on your insurance or headers, remap, end can could affect your warranty then id leave it well alone and put up with the shit fueling cos all you'll do is you'll be sweating when it comes to collecting your bike from a service etc..... life's far to short

Has anyone put forward a warranty claim on a bike with remap is the question.

 

[pistole]

no issue with the throttle response.

 

[matchbox]

Wudee. Have you tried Rain Mode. This slows the response a little and you can overide suspension setting.

Same for me, I stay in Dynamic mode mostly and love the instant throttle response, I sometimes switch to rain mode when I've got a pillion on board as it softens the response and stops helmet clunking. I've had 2 twin cam's before this and can't say I'm disappointed in the throttle response compared to those.

All I want to do is find time to get to Hilltop for a remap, for no other reason that it worked wonders on my last 2 GS's

 

[Fluffmeister]

Yes, but on a twin cam, and had no problems with the warranty claim. It was a gearbox issue that was remedied under warranty a couple of years ago.

Far be it for me to argue with the bossman But is that statement 100% accurate. If the flash counter is not being updated on the ECU, or the ECU itself is not being opened then I'm not convinced that the Diagnostics will show it. I'm only going on my own experience with vehicles being mapped. A good friend had his 123D mapped by a BMW specialist in Crewe, he's had an injector fail on the mapped car, diagnosed by the dealer using their diagnostics but no problem putting it through the BMW Approved warranty system.

I had a turbo issue on one of my previous Skoda's that had been mapped by Shark Performance, whilst under warranty. It was dealt with under warranty, and they had the VAS rig hooked up to the car to help diagnose the failure and either ignored or never spotted the map (It was an actuator failure, so not directly attributed to the map)

I'm not saying you could not find it, but it may well take a deeper dive into the ECU than the dealer diagnostics kit is capable of, people do have to be adult about it though, if you have a bike or car mapped and it goes pop and it IS discovered the bike has been mapped, then you have to be prepared for the worst.

On car's in particular though, the question of "can a dealer tell my car is mapped?" is always a funny one, because IMHO if the dealer test drives it and all is normal ......that's a pretty shit map

 

[DING-DONG]

Yes and everything was fine as long as you tell em nowt.

Who told you this ! Because honestly I think there were giving you some BS.

I do no the ecu in the bm cars did at one stage have anti map loading and any attempt to plug in and remap via the dio would shut down the ecu and only BMW could revalidate the ecu. But the hackers got around this.

I do think it will not be long before the bike software has the info to tell its been spiked/flashed, so you pays ya money and takes ya chances.

 

[Davel]

I have to agree with the OP.

I'm pleased with the overall improved performance of the new bike and the handling, but I do find the throttle a bit erratic at times as you can suddenly end up with loads of revs when you weren't looking for them.

It hasn't been an issue for me but I understand the concern.

 

[Paul G (BHT)]

.... is that statement 100% accurate.

I have a BMW 335d that I have been paying an extended warrantee on for the last 3 years at around £600 per year.

Christmas Day, last year, the valve that operates with the small turbo failed so I took it to my local dealers safe in the knowledge that it was under warrantee.

A short time later they called saying our diagnostics say your car has a modified engine so the warrantee company may not pay, it was BMW approved warrantee by the way.

The only mod my car has is a re-map, no chip just a re-map. Sure enough the warrantee company said go do one, so I had to pay the £625 for the job.

I have never paid for extended warrantees on my bikes and now wish I had done the same with the car.

Apologies for the slight thread hijack here.
