RE: Why our Elise went into limp mode

[Clivey]

Oh great...more nannying crap that we don't need or want and that doesn't appear to be easy to disable.

[dukebox9reg]

Might be pedantic it doesn't mean you cant left foot brake at all. Just means you cant left foot brake and keep your A)lazy trailing foot on the throttle or B) keep the revs up.

I left foot brake and have had no issues with DSGs etc.

They've probably already re-written the ECU code to disable it and are busy getting on with their lives

No - it's happy as long as you are off the throttle before you get onto the brake, so H&T will be fine. Left foot braking is the issue.

Nannying bks to avoid being sued by incompetent geriatric Americans who couldn't get in or out of an Elise in the first place.

Yeah because the huge UK market should govern decisions car manufactures make..... pfff I won't bother looking at the numbers but I am confident Lotus has a larger market in the US or at least pottential market anyway. The ignorance on PH astounds me.

I would imagine that the majority of American Lotus buyers are not incompetent geriatrics and would dislike the feature as much as anyone else.

Does seem an odd thing to put on that sort of car but I don't left foot brake and it sounds like it wont affect heal-and-toe so I don't think I'd ever hit it.

This happened to me the other day in my Land Rover when I was wearing flip flops.
But even then it just flashed a red light rather than go into limp mode.

That was just the LR's way of telling you it disapproved of your girly footwear.

Shame systems that are there to protect people too stupid to drive properly compromise driving for the committed enthusiast.

I've mashed throttle and brake occasionally with my huge clod-hoppers. But I've always also mashed the clutch pedal so not such a big issue, just silly engine noises, which you can't hear over the horn anyway

But seriously, heel and toeing through a manual g-box while blipping the clutch to chuck it down a cog should still be fine because you've come completely off the throttle for the brake into the bend, so that works.
It sounds like you just didn't get your right foot completely off before tapping with your left.

This only happens in cars without a clutch, another argument to use old fashioned manual gearboxes.

There is no two-pedal Elise.

Automatics are different for obvious reasons, but why would you be left foot braking in a three pedal car if you didn't want to have your right foot on the gas?

In laggy turbo cars, driving gods (all of PH) can use a bit of left foot braking to stabilize the car and start building boost at certain points.

I used to try this in my MR2 (on track), never quite got the hang of it. Taught me a lot about spinning.

Sorry, but can't help being pedantic. It should be sceptical; Only Americans (fat-footed or otherwise) write skeptical.

I know, I know....

I wouldn't bothering trying to correct all the errors in PH editorial. You'll be at it all day.

Yes, by using the brake and gas at the same time. I understand what LFB is for, I just don't see any application for it in a manual car when you wouldn't also be using your right foot for the gas. If you aren't doing that you may as well brake with your right in the normal way.

[Some Gump]

As much as I appreciate that 1% of owners might left foot brake, I understand why this system is a benefit.

I've had 2 scary as moments related to this - a snapped return spring on a V12 E type, and a failed throttle body on a 7 - both left the throttle jammed open, and were only discovered on braking!

I _think_ that the modern Lotii are drive by wire - so this system does save you from a fault / sensor issue. For 99% of owners, I susepct they'd never find it. OK there is a good excuse for a "track" mode or whatnot, but to suggest that the presence of a safety feature makes Lotus a nannying USA led shadow of it's former self is possibly a tad overoptimistic...

[kambites]

I've only had a throttle stick open once (on my MGB) and I can't say it was particularly worrying. I just brought the clutch back up in fourth and stood on the brakes.

I suppose on a modern high-torque turbocharged engine it might be a bit different, but I'd imagine any modern car has brakes that can overwhelm the engine fairly easily as long as they aren't already overheating.

A can't imagine fat footed Americans buying an Elise anyway. Or am I just sceptical about UA for the vast majority.

Erm. The Elise isn't sold in the states. Only the Evora

It was for a while, before their "headlight height" exemption ran out.

There are several Elise mules with IPS system fitted, dating from a few years back i think. Somebody with me on a track day thought the development was aimed at the far east market. None came to production.

[MentalRental]

I left foot accelerate and brake every time I drive as I have no right foot. Maybe that's why I walk around in limp mode.

Amputee humour. Whatever next
