Need help Attaching Z32 to 92' R32 GTS-T

[Cubes]

Hi ppls,

I am about to attach my Z32 to the R32.

Upon inspecting the origional AFM wires I found some thing a little strange.

(see pic)

Is this normal for an RB20t to look like this (2 wires going in to 1 coax)?

I've attached the R33 S1 wiring instructions pic that will work with my rb20t as I've had a R33 S1 AFM on my R32.

The wiring instructions don't state the pinout for the r33, only the pinout for the Z32.

Would any one know the pinout for the R33 S1/R32 AFM.

I wouldn't want to run 12v through the signal.

Thanks ppls.

I will have a look tonight Joel, I remember I used that diagram, plus a few other things I wrote down in my little car book I keep,

I know for sure the coxial part of the cable was not required to be soldered to anything, mine looked exactly the same when I stripped back the black plastic

will post it up tomorrow

Excellent. Thanks buddy.

No probs

I remember Roy telling me about a certain workshop in Vic that was swapping wires on his AFM while the car's ignition was on to work out which was the right one! Dodgy!

[Cubes]

I've been doing a little fiddling ( not wire swapping )

It appears quite straight forward.

The Coax shields both the signal and signal ground (Unlike the Z32).

Pin outs are exactly the same.

I need you to still confirm it if you can Chris.

[Chris32]

Will double check it tonight and post up first thing, its pretty straight forward

sorry to butt in! .. i'm about to connect the z32 AFM to my r33 gtst s2 (3 pins), could anyone tell me what to connect to? thanks.

The Z32 runs and idles fine with the VG30 AFM selected in the PowerFC.

It still hits down at load point 19 @ 2000rpm.

I thought the Z32 was supposed to give a little more head room in the map?

[R31 POWER]

Jesus that monsta must swallow alot of air!!!! I get around load piont 12/13 while hurting it lol

[Cubes]

It is still running on the base map so i'm unsure if anything will change when it is tuned Tuesday next week.

lol.. A free rev to 5000rpm hits 100% duty cycle. Can't work that one out, mind you it is boosting on a free rev. lol

Shall be very interestering how much power it makes on the stock turbo @ 11psi.

It feels much quicker than the rb20det running 16psi.

[R31 POWER]

Keep us posted Joel.Will it be tuned with the standard turbo? and if so is it just a quick tune to make sure it's safe to drive.

[Cubes]

The AFM voltage in the sensor check definately reads lower.

The highest it now reaches is just over 4v.

With the rb20 afm it was hitting 4.98 volts.

So it must be doing something.

Just strange how the load points on the map still read the same.

It will be tuned with the std turbo on 11psi. bar & plate FMIC & 3" turbo back exhaust, std injectors, std airbox + 100mm cai into the inner guard.

It is just a 1hr quick tune to tidy up the map and throw a little more fuel in the bottom end and mid range.

I dont want to spend too much on the crappy std turbo. Only to see how it goes with the 3ltr out of curiosity.

I'm keen to see where peak power is made, I've heard of some making peak power (150-170rwkw) around 3500-4000rpm.

I pity that poor old std RB20 turbo of yours...im sure its going to love retirement, that sif you dont brake its back before it steps aside:)
