Thoughts? More responsive throttle

Lmao, not everyone is a yob joe
i certainly won't be investing in one. You can achieve the same thing (more throttle opening for less pedal travel) by changing the right part of the map if you really want.
I'll be fitting a proper ECU as soon as possible. That will sort out a huge amount of the limitations put into the stock ECU for emissions regs

i had a brief chat with chip about this, he said youd have to swap ECUs if you wanted it more responsive... im not sure if it is mappable on the standard ECU
Sorry mate, not online much at weekends as normally busy working on my car instead, so only just seen this thread.
Bottom line is there are mechanical factors limiting how fast the pedal itself can move, and also there is the whole issue that the ecu needs to look at the throttle pedal to decide on your request, then it needs to look at the position sensor in the throttle itself to decide how far it is from that, then it has to actually move the motor to that point, and all these steps take an element of time, the net effect is that the combination of them adds up to the fact there will be a slight delay between you moving the throttle pedal and it reaching that point on the body.
What all these devices and remaps do, is just take away throttle resolution, they make it so that when you open the throttle a quarter of the way it opens half instead, that is NOT making it quicker to respond though, its just making it less accurate, as you end up with only half the travel meaning anything, and you could have achieved the same effect simply by moving your foot further.

Changing the throttle resolution can be done in the map, but that isnt the same as making it more responsive, people dont seem to understand the difference.
Lack of response is you want 50% throttle and it takes a while to give you it, whether you alter the map to tell it to give you 50% throttle at 25% pedal travel wont change how long it takes to give you that amount of opening, it will just mean you find it harder with your foot to request exactly the amount of throttle you want.

i drove my mates old one with the sport button on, it was a brilliant little car
so, people on 197.net are going to be upset and wanting a refund soon?
No, they're just blissfully ignorant of the difference.

Depends what they want from their car, if they want a hair trigger as a throttle that means when they apply a small amount of throttle angle then they will be happy, if they want to accurately control the throttle angle they get to hold the car perfectly on the balance point going through a corner then they will be unhappy.
I suspect they would see a tiny decrease in delay time, because the delay is starting while the pedal is only halfway through its travel, therefore by the time the pedal reaches the bottom of its travel a tiny part of the delay would have elapsed, but it's not worth it for the loss of driveability.
Only in the time it takes them to move their foot, not in terms of the time the ECU takes to respond, and the reality is that when you try and move your foot a smaller distance you'll do so slower naturally anyway to try and keep control of where you are moving it to.
That's what I said
