green light for changing gear...

[kyle172]

is that little green light telling you when to change gear set for optimum performance? will this change if any mods are done to the car or whats the score yall???

 

[Griff]

It's a "you should have changed gear already" light. It's not there to indicate the optimum shift point.

 

[ditz]

no,, thats a "change gear before something goes bang you t**t" light

not optimum change point

 

[gregwilliams333]

its a shift light not all 172s have them, i dont think it would change prob set when just before the red

 

[Christopher]

It's definitely the optimum shift point light.

 

[kyle172]

haha thought so. a friend who has a 172 told me it was when to change gear his engine must be fooked lmao thank f**k i aint been doin that

 

[Dickie_172_cup]

seen mine come on a few times lol

 

[Turkish]

As already said it's a "here comes the limiter" light not an optimum shift light.

 

[-Leigh-]

I had mine on in 5th a few weeks ago.

 

[Bash]

The light goes orange on diagontics, I wish I could make it go from green to orange when it passes optimum.

I also saw it on saturday night, on my private road...

 

[Merk]

I actually redlined my car once just to see if the green light actually came on...

it did

 

[Adamhodg]

only ever did it once to see if it worked and it did!

 

[C.J]

So, when is the optimum? And when does the light come on?

 

[Timmay]

i used to floor it a bit just to see lil green ight come on - tis fun

 

[Russ_16v]

So, when is the optimum? And when does the light come on?

Changes from car to car mate, even two standard engines can have different peak power points

as a very rough guide i would say around 6800 for the 1st 3 gears, then a lil lower for 4th

but then again mines different and seems to hold on for longer and seems to still pull higher than that, every lumps different. i found changing at just over 7k gets me my best 0-60 time (6.48 secs) but if i change at 6.5k that drops to around 6.8 ish but runs a faster q/mile.

 

[Dash]

If you see it in 6th gear it's usually followed by a blue light.

 

[Josie172cup]

the 'shift light' comes on a few hundred revs before the limiter kicks in as mine changes with the ecu when the car warms up

 

[PeteCup]

Mine seems VERY close to where the peak power feels to be so works out well as a shift light.

 

[nickl360]

Yeah, it's there to protect the engine and components.

It sometimes catches me unawares, I'd floor it and then glance down to see the revs just in time to see the shift light. Ooops!

:lolup:

I've had it in fifth in the cup, but no blue light - well not one that caught me anyway :evil:

I wonder what speed it is in 5th. I never looked at the speedo. Was too concerned about sheep running across the private runway I was driving on.

140mph ?

 

[nickl360]

138mph is the stated figure, which would probably look like 145-150 on a speedo.

 

[-Leigh-]

138mph would be about right, I imagine the speedo was at about 145mph. The new focus st I was against started pulling away from me just before the light came on so I presume they can go faster. But they're no faster up till that speed.

Have to get on the runway again somewhen, with my sat nav on so I can check gps.

 

[Mr Burns]

Mine flashes so much I thought it was the indicators!!!

...this is a joke btw

 

[Andyman]

Just after i got the car i found out mine didnt have one when it smacked off the limiter in 3rd

 

[Stuart182]

I had mine on in 5th a few weeks ago.

LOL!

 

[Tom84]

i swear mine goes green then turns orange when u keep going. i know for a fact that ive seen it orange

 

[Gaz_]

197 shift lights ftw!!! You can actually see this one, not like in a mk2 Clio

 

[Nick_D]

haha thought so. a friend who has a 172 told me it was when to change gear his engine must be fooked lmao thank f**k i aint been doin that

Is this the - my mate has an ugly bird but she really goes sindrome - meaning yourself??? :rasp:

 

[evolution]

I know everyone is saying its a "shift now or else you're buggered light"

BUT....


I've got a 172 brochure in front of me and in the features section it says.... and i quote, "OPTIMUM GEAR SHIFT INDICATOR".

Just to confuse matters.....

 

[john.med]

Scan the brochure lad and host it somewhere like putfile or the like,.. I'd be interested in seeing the original shizzle from Reno.

 

[Big Iain]

In 5th!
