It could be the fly-by-wire throttle. I remeber reading that it takes things like the incline of the road into account. What other variables does it take in an to calculate throttle position?
Yeah, if the car is stationary, it revs faster, but if the car is in motion even if it's 1 or 2km/h, the intake changes and revs lesser and less energectically... those with aftermarker filter will be able to tell the difference from the induction noise.....Quote:

Most of my driving is city based. When I do get to stretch the Euro out (say 400kms of highway in one day) - I always seem to find the next day the engine is really keen and revs amazingly well and fast.
Has anyone else noticed this? eg after a long drive - more power? Weird.
I find that if you have the A/C on, K24's response is really sluggish. I found between yesterday (35 degrees) and today (25 degrees) that a higher ambient temperature does take away response, but not as bad as A/C. So if I drive in 35 degrees without A/C, it'll be more responsive and probably more powerful than at 25 degrees with A/C on.
Its your gearbox.
It remembers your last 40 changes meaning that if you drive it hard it thinks you want to drive it hard from now on. If you started driving slow towards the end of the day the gearbox thinks its slow again.
But our gearboxes are manual. So the only thing that the ECU can change is the throttle position through the electronic throttle.
I think you will find thta the electronics of the car are remembering how you were driving the car previously. I will take time to reset the throttle response & auto transmission change pattern to your "new" driving style. There are many other parramaters that the car samples to adjust the car. It will even adjust the brake pedal response according to your driving style.
Throttle response, yes. But the brake pedal response is not influenced by the driving style. The brake assist from the ECU is an off-on switch. It cannot apply brake pressures in between. And, yfin drives a 6MT, not auto.Quote:

Its not just the temperature that caused perf degrading right? Sometimes on a warm day my car runs quite well, which leeds me to believe it also depends on the humidity, and off course Oxygen vs Nitrogen vs CarbDiox ratio's.
It also runs better on a full tank of fuel, but wouldnt that slow the car down - being 50kg heavier?
Plus if I thrash the car, it doesnt perform that well. But if I take it easy @3000rpm changes, it runs much smoother and feels more powerful (probably because the engine is cooler), or the ECU thinks Im a granny :P
I find that sometimes when I try to rev the Euro, for example to overtake someone, it might or might not give me the acceleration that I anticipated.
So if I see a gap I sometimes cannot make it, but sometimes I can.
I've since found out that in the Euro - it simply lacks torque everywhere - so that if the road is only a smidgen uphill it just doesn't like to rev, whereas if the road was even very slightly downhill it would rev uplike crazy.
That is the result of trying to spread out the torque delivery and making it a very linear power delivery despite its design for more torque over the K20A.
Especially compared to say a Magna or Falcon which have much more torque everywhere except at the top end. Meaning in gear acceleration wise all are equally as fast, sometimes even faster, but a lot of times slower if caught in wrong gear. Seems to depend on the incline too.. :o
