VTEC in reverse?

[infurNOS]

I have been told many things about hitting VTEC in reverse, most of them say it is disabled once in reverse, but USDM versions seem to have no problem doing it:

whats the truth behind it all? unless the USDMs ECU's are different or VTEC does really engage in reverse

[CB7_OWNER]

Looks pretty legit... prolly have to go out and try it out for yourself.. loollool

[infurNOS]

yep
lol

Adjusting damper on stock shocks and now this.

[ECU-MAN]

you can hit VTEC in any gear forward or revers

only factor is you have to go faster than 30Km/h or it will not kick in

the PGMFI ECU does not know what gear your car is in on MT

[kazam]

y do u wanna hit vtec in reverse LOL

[tayl51601]

Plus you need to be doing at least more than the RPM that vtec is set to kick in at......... I dont know where the revs normally are in reverse because im usually looking behind me lol

You have to be nuts though to want to reverse with vtec haha

whats your point?

[hero]

will the speedo hit 30kmph if you car is going backwards.?

if its on teh old speedo cable ones.. you k's would go backwards means you would be -'ve kmph

[hywindz]

Exactly, what is the point of this question? Just a hunch but I think Tai is trying to say this thread is pointless.

The speedo on your dash will not move no matter how fast you go on reverse. Unless you have a digital speedo or an RSM.

the odometer might go backwards on a cable speedo but the ECU only see pulses of 5v. so it measures as forward speed

not true

the VSS sends signals regadless of direction. and its the same signal in either direction

only cable Speedo wont register

[hero]

jsut 12v the vtec soleniod to kick vtec in.

why not for the hell of it and put it on uptube

Fair enough with that theory. But I don't remember my speedo moves in my EG and DC2 when I reverse my car. I only see my RSM indicating the speed.

I'll try it later after work when I collect my car later. :)

to reach 88mph and go back to the future fa sho

hahha my vtec just kicked in backwards yo!
is there such thing as racing backwards?

[migoreng]

how about dyno your car in reverse gear?
:P

[OMG.JAI xD]

Mates done it before.

On a dc2r with i/h/e. Vtec DEFINATELY kicked in.


Reverse gear gets pretty loud at those revs though.

[STTICH]

wont that be 'ouch' in the gears? lol

Hey ECU-Man, speedo moves as I go faster when I was reversing. Thanks for the great info. My bad for giving wrong information.

:)

[garagedefend]

yeah it can. you can also do it in neutral if you've got the box set to do a standing vtec xover

thats right

usually when your going fast enough in revers to make the needle move you not looking at the needle, your looking behind you :)
