Vein Pressure Converter wiring WTF??

[SumKid]

Ok guys so i have a 1ggte VPC and a TV-04 wiring harness.

Does anyone know how the harness is meant to be wired? can take pictures of what it looks like if needed.

I hear your meant to put some resistors in??

I found this site but not for 1g, is it the same though?? http://www.alltrac.net/tuning/ST165VPC.html

Any help will be appreciated


Thanks Seb

ah dude my suggestion is get rid of it man
is this the 1 that eliminates the afm??
i have had one before and then my car didnt end up working. got rid of all the piggybacks n did 1 standalone and car ran sweet.

[SumKid]

Yea gets rid of afm, if i had the money for stand alone i would lol.

i just want to see how this goes (got it for free) if it works and can tune it a bit il be happy, then later go stand alone.

[GU11TY]

actually i got 1 in my 7m at the moment
i got sum wiring shit here to i could put up.
sho us a pic of all the bits u got 4 it and ill let u kno wat ur missing if u are

[thechuckster]

and while you put the pics up, include the letters that Gu11ty missed while typing his post?


The air temp mod referred to in the alltrac link is about making the ECU think the incoming air-temp is 68 degrees F (about 20 degrees C). This makes the ECU run the motor rich as it thinks the air is cooler (and thus more dense) and possibly less retard on boost.

This will mostly add to the black crud already fowling the spark plugs (boosted toyota motors always run conservatively rich on boost) and fills the exhaust with extra carbon soot.

Ok so everythihng..




And harness but blue wire isnt attached anymore and i know what the brown wire does.



number 2 is red with no dots, no trace. it is connected to a white wire, brown dots, black trace

number 3 is a blue wire with brown dots and a red trace, its tapped into a red wire with black dots, no trace.

so..........

what the hell is number 2 supposed to do, or does it just hang there cut?

is number 3 supposed to be like that? the blue wires were originally seperated, i colour matched them figuring they are supposed to be like that? otherwise they just hang there... it seems logical that they were once connected

Soo what your saying is dont bother? lol. Do you know what the red wire is meant to connect to? and if the blut one (3) is meant to be connected ive been told its not??

Thanks Seb

yeh man. my current car used to run sweet
now with the vpc its slower unless ive just gotten used to the speed and yes runs rich and starts blowing smoke. im gonna pull mine out in the next few days

VPC = GOOD STUFF had that on my 1G with "custom" twin pipes to each turbo and it had massive induction noise!


YELLOW = tap into afm wire at ECU
let me find my documents and ill get back to ya

Yellow? with red trace? goes into the 9 pin harness (with green and black wires coming out of it) i alreeady have induction noises single though..

Cheers guilty, but i need the actualy harness wiring too cause as you can see in the pictures its been cut up

[GU11TY]

nah its ok its cut. im pretty sure mine has a few missing wires goin nowhere aswell
i think they r for incase u wanna connect the other piggybacks from the hks range like the fcon, gcc etc.
cause my other car i had a fcon, gcc, vpc, boost cut and man wires were everywher

Haha ahh well i will try with cut wires and see how it goes, do you have any pictures where you put the temp sensor?

[Kedderz]

Seb, save for a aftermarket mate. The VPC even if you get it working (doubtful) is a poor substitute. It has a very small tuning resolution and good luck trying to get someone to tune it, let alone do it on a budget in canberra!

Im 100% sure that the mines ecu you have and a fuel computer ala safc2 would be better than the VPC and 1million times easier to install.

[JZA70R_92]

My 1st VPC I ditched the connectetor and wired up stright to stock wiring. I had VPC + GCC and my car ran fine after some on road tuning....No more ugly afm!

[SumKid]

Kedderz:
Yea that is an option but doesnt it still use the stock maff? main reason to do this is to get ride of it! lol. preferably id like to go stand alone but dont have a couple of grand spare with this engineering going on

GA70H_92

haha dont really wantto go that extreme and most of the engine harness is hacked up enough. yea just road tune it to get it running, i wouldnt be tungin it for more power just mafless

[Kedderz]

It still uses the stock AFM yes. That said AFM's have proven to run to at least 200rkw. Theres no point in just getting rid of it for the hell of it, you do it for a reason ie remove the restriction to go higher power.

[SumKid]

It is to remove the restricion, ive heard poeple use ba falcon afm?? or was that just the air filter lol.. The turbo on the car isnt even getting to its power usage! lol 280-475 hpone and cars only makeing 240 maybe a bit more lol. so as little restriction and a bit of toying with id be happy.

[Kedderz]

I think your on the money for stock management. Blake ran his with a 3071r with a .48 housing and that was at 190kw at about 12 psi on stock management. The VPC isnt worth it mate. Get the car engineered and rego'd then fit an adaptronic or something which is a million times better than a late 80s early 90s piece of equipment which you wont able to get tuned properly.

[CrUZida]

What makes you think the AFM poses any restriction?
