So how exactly do I get the tachometer to work?

 

How much is it worth to know

Just kidding,

If you look at the ignighter there is a blank hole in the connector with no wire in it. Pull a pin and wire out of your olf harnes and run it to the wire in the ECU box that feeds signal to the tach. I don't remember the wire off the top of my head, but if you have a schematic for the GS300 you sould be able to find it.

LOL!

I'll have at it. Let you know soon.

 

burgandy Gs, doesn't the GTE come in vvti also?
and what to do with a standalone or other type of engine management and stock OBII ecu? for inspection purposes (NYC requires Plugged in OBII scan 95+ ) My supra just needs to be dyno inspected pre 95 . Thats what my 1st problem to begin with was the VVTI and the ECU/management? only reason i've been hesitain for so long on the boost. I'm addicted to the boost, it's killing me to live without it lol thanks

 

got a question, how are you guys locking your gear to 3rd to put on the dyno?

the aristo shift selection is P-R-N-M-D-2-L

Mine is a 99 with P-R-N-D-4-3-2-L

When i put it on D.. it's drives up to 4 gear..
when i put it on 4.. it lights up 3 on the gauge but works like D
when i put it on 3.. it lights up 2 on the gauge and goes up to 2nd gear only
when i put it on 2, it's on L with the 1st gear only.

how am i suppose to lock it on 3rd to dyno it?

is this normal?

 

Your supposed to dyno at 1:1 which is 4th gear w/o od

 

isnt 1:1 at 3rd?

1 --- 2.804
2 --- 1.531
3 --- 1.000
4 --- 0.705

 

Those ratios dont look right for some reason. Usually 4th is 1:1 on 5spd cars
be it auto or manual. In 6spd trannys the fifth is usally 1:1

I suppose its possible though. Where did you get the data ?

 

talking about a 2jz-gte VVTI.. it's a 4 speed tranny.

 

Correct me if im wrong but isnt that a 4spd with o/d ? Thats what my vvti ge is.

 

Yes it is so i dunno why you thought it was a 5speed on your previous post and telling me to dyno it on 4th.
Your first gen GS comes with VVTI?

I dont think you understood what I was asking.
I was asking the vvti GTE swap guys how they get it locked on
3rd since there's no gear selection for 3rd on the JDM tranny/shifter.

The Aristo V300's shifter gate goes
PRNDM2L (No selection for 3rd)

On My 99 is PRND432L

I'm only able to select D 2 and L on the driving modes.

So what i'm trying to find out is how to get it on 3rd to dyno.

 

EDIT: I just re-read your post for the 50th time. If yours is a 99 with PRND432L
Thats a 5spd not 4. Im probably making a mountain out of a mole hill. Where did you get the info on the gear ratios. That would clear up everything.
The below info was before I edited the post

I was under the impression that it was a fourth + o/d. That would effectively make it 5 total speeds. I drove my 94 gs3 today and it does infact go P-R-N-M-D-2-L like you said. So thats actually a 3spd with o/d = 4spd. For some reason I thought it went PRN432L with the o/d switch.
And no my 94 doesnt have vvti I should have been more clear I also have a 99gs3 also and it has the PRND432L that you talked about so 4spd +o/d = 5spd.
To answer your question - I have no idea

I've only dyno'd one auto before and I just took the o/d off and wound it up thru the gears slowly untill I hit 1:1 and brought it up to the speed where it would no longer downshift and laid on the gas.

 

I'm not using the GS300 tranny so i dont have the 5speed anymore. I'm using the 2jz-gte VVTI 4speed tranny.

Got the gear ratios from mkivsupra.net

 

Sorry, I made that clear a mud for ya. Hopefully someone else will chime in.
If not, start a thread about how to dyno an automatic and pm me with the link.

 

thanks for the help though. maybe i made it confusing with my wording.
