Fiat 500 poor throttle responce!!
I have had my 500 for a week now and the throttle responce is driving me crasy. Is there anything that can be done to improve the obviously flawed drive by wire signal? Nothing happens for 1-2 seconds. The driving becomes very jumpy I also think that 100hp on such a small car should produce better performance, I could not keep up with a old man in a 1 litre toyota yaris.

A re-map should sort this. But then it should not be the case in the first place.

I had a very similar throttle responce issue with my mothers Honda CR-V. Her's was a mark 2 and Honda had change alot since they made my Mark 1. It felt slower but then i got used to driving with it and i noticed how i was getting better mpg because i was'nt 'beasting' it off from the lights.

simple answer take it back to dealer but i can tell you now there is nothing they can adjust or change most they can do is check for updates and just generaly look at the cars engine data wilerunning to see if anything is a miss i haven't noticed a problem nor have i in the earlier 100hp pandas similar engine

obviously being a 16v there is not allot of torque lower down the rev range in fact the 1.2 gives more poke from 1000 to 3000 rpm

the 1400 16v comes in to it's own above 3500 and more so from 4 upwards

the throttle response is nothing to do with the fly by wire system

on a car with a throttle cable if you were to snap the throttle full open you would have less power than if you were to sneak it open as rev's and speed increase go out in a cable throttle car and give it a try

when you demand full power from the ecu with the throttle pedal the electronic throttle on the engine is open only to the optimum opening for that engine speed and load and no more that it needs to be

if you were driving the car with a manual throttle you would find it had a bigger delay so don't go blaming the fly by wire it is in fact helping you in removing the human error

if you want to blaim anyone blaim the eu for imposing such strict construction of use regulations you must remember your car is a euro 5 emissions compliant car so even thou it is a 1.4 and supposedly has 100hp don't expect it to be a rocket

at least round a track it's quicker than it's rival the bmw mini 1.4 95hp witch we don't get in this country 5th gear did a comparison

also remember a toymotor yaris weights nothing made from old tin cans and also has that vvti rubish bolted to it so actually has quite a bit of poke considering the engine size

Click to expand...

how much did he weigh?

as the itallians say revit~harder

rev it, and rev it... and rev it untill the valves come out and dance on the bonnet and THEN change gear

all will be well

it's a f.i.r.e. engine anyway they like to rev lots the 8v version is safe to 9000rpm

I had this with a 1.6 Stilo. throttle response was dreadful and all to easy to stall at junctions. Fiat technician showed me how bad the delay was when trying to blip the throttle. Nothing could be altered so the car went. Previous 1.8 Stilo was much better. I've got a 1.2 04 Panda as an everyday runabout and a 100hp for a bit more fun. Obviously the 100 HP is ultimately quicker, but the 1.2 is much quicker in responding when pulling away. HP has sport button on at all times. I've owned some quick cars with throttle cables and they have all been better. Move one end and the other moves. No contest.

Its actually not too bad a wire system, the Micra 1.2 I had was awful, you could drive along and push throttle to the floor, let it up instantly then floor it again and the engine wouldnt respond at all!

I'd love to talk to anyone who's able to REALLY remap the car. Problem with the remaps I've seen so far is that the people doing these remaps don't really know what they're doing in what part of the map. They program some software which has been developed by someone else which stops them from doing their own thing

Throttle response is a function of the mapping of the car and is rather conservative because of the all the EU rules. If you could really open up the ECU, I'm pretty much convinced you should be able to create a very neat mapping which would make the 500 a very nice, responsive car to drive

My re-map has helped response, torque and mpg. Happy, but would love to see what happens when someone as you state really gets hold of it....
