RE: Why our Elise went into limp mode
Discussion
I'm a bit disappointed there's been 3 main page features on this issue. Whilst one has served to clarify, it's negative press which Lotus don't really need. I've owned 2 Exiges, and they have been far more reliable than the 997 GT3 I owned! Most cars throw a CEL in their lives. That said the trail braking issue is of interest but could have been highlighed in a less dramatic way.

so because as a company they're in trouble it should't be mentioned?they in trouble exactly because of this kind of thing, the real question is if it wasn't pistonheads if they would have been so helpful, i suspect as journalists they receive a level of care that the poor people who actually pay for the product can only dream of

They're in trouble because they produce a car with a feature that just about every other car on the market has? As opposed to Porsche are are in rude health because they produce cars which only catch fire? they in trouble exactly because of this kind of thing, the real question is if it wasn't pistonheads if they would have been so helpful, i suspect as journalists they receive a level of care that the poor people who actually pay for the product can only dream of
Maybe as well as chipping a car for more performance, you will be able to chip it to remove this glitch (aka safety feature). This happens in other VAG products not just DSGs I think? I was trying to left foot brake (rally practice you see!) the wife's Touran FSi and it cuts off the throttle. Painful!

You miss my point. Personally I feel this is a minor issue made into a news story, mainly due to reliability issues which are well in the past (as an ex owner)they in trouble exactly because of this kind of thing, the real question is if it wasn't pistonheads if they would have been so helpful, i suspect as journalists they receive a level of care that the poor people who actually pay for the product can only dream of
I'm sure many PH cars have thrown a CEL unreported.
But I'm glad the have now clarified it's the same on all modern cars.
This sort of system has been around for years .
If you try driving my 997.2 GT3 down the road with one foot on the accelerator and the other on the brake to dry out the discs after washing the car the engine cuts out until you release the brake .
Not many people criticise this particular cars track behaviour .

Not really understanding the need to put the car in to limp home. It's somewhat overkill on a car that will drive on track. A better strategy would be to reduce engine power after a time period (say around 1s) of both the TPS reporting greater than 10% and the brake system reporting greater than 10bar. Once the conditions are removed (i.e. once both throttle and brake are removed) have another timer upon which full power is restored. Then there's no need for an ignition reset. This is exactly how VAG have achieved the fail safe for the last 15 years!
This^^^ I suspect the "Limp home and spanner lamp" were NOT caused by the throttle logic!No other car i have every driven (or calibrated) goes into hard limp due to a throttle/brake arbitration clash, they just ramp the throttle plate angle back to idle (or if there is a throttle fault, cut the fuel to prevent a positive torque output) for around 5 sec, then when the arbitration clash is resolved they ramp the throttle plate back to the drivers torque request.

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.
SPS - a hydraulically operated version of the Toyota EC60 gearbox (in the Elise SPS) or EA60 (in the Evora GTE). Both were canned as they couldn't get them to work well enough afaik.IPS is the Evora system which uses the Toyota U660E torque-converter automatic.
I BELIEVE the Elise SPS mules were converted back to manual cars by Stratton Motor Company and sold off. They certainly had one for sale a while back.

Most people with any sense use the clutch and the gear stick into neutral to overcome any throttle sticking issue, then key off the ignition.
The same rubbish was spouted when we had the spate of sticky throttles on, was it Hondas in the US? Turn the key off you morons!!!!!
We don't need this sort of override on our sports cars, especially not Lotuses!!!!!
