[acesinghit]

questions:

What size rims you running on your car and what type is it?
when last you changed oil, oil filter, spark plugs and air filter?
when last you did an EFI service?
what fuel do you use and where do you go?
what is your tyre pressure on all four corners?
how much people/weight did your car have at the time or currently has.
What size engine you have?

what ignorant ignis mentioned is also valid etc...eg. your engine sensors.


cause that 150 seems 30kmph off what some members getting on theirs.

^^^well.....

1) Corolla does have a history of speedometers being off a bit
2) the heavier rims slow down your car
3) you need to re-service that car
4) that music adds weight
5) you had full tank of gas?
6) you a heavy fella?
7) your floor mat or mats prolly obstructing the accelerator pedal so you prolly thinking its fully depressed.

if all above doh apply to you then I out of ideas.

highly doubt it... SDM?

jus troubling you... but seriously thats odd, as said before.. the speed cut usually kicks een at 180... but you did say you have 18"s and two rf in the back..

srsly get that checked out.

You're suffering from budget-car-itis.

that doh matter the new thing in trindad is to jump across the medium and see how much cars you could take out on the other side.

Don't forget to pull in front oncoming vehicles to indicate you want to change direction...nevermind the speed they're coming at.

[XMasterX17]

yea fellas, i hit 185km when i mash down with the o\d off

[3stagevtec]

that's kinda odd.. it seems like there is an electronic limiter associated with the overdrive..

did you try it with the o/d on and off at the same time? to rule out other factors...

agreed....

yea i did, it felt like gears were changing while i was doin it, when it was on it stayed at that speed.. didnt accelerate

[Midnight_Demon]

thats cuz the overdrive does not allow the transmissiong to go into the final gear.
i.e. if is a 5 speed tranny and overdrive is on it will stay in 4th gear alone. take it off and it will go into the 5th gear

amm, isn't overdrive the final gear?? so if it's on, you should have access to all gears...

he has a Toyota Corolla Altis NZE121 chassis which comes with a 3ZZ-FE engine and 4-speed ECT-i automatic tranny?

question: The 3rd gear in the automatic tranny was designed to take the car at top speed also right? Hence the overdrive is 4th gear to allow the rev counter to drop to about 4k rpms to save fuel but still keeping the speed. If the Corolla remains in 3rd gear running past 5k rpms it can damage the engine hence the O/D in that instance right?

I see similar set-ups in Nissan Almera, Mazda 323 and Hyundai Elantra to name a few.
