or remap your ECU...

Which is pricey when all you are doing it for is an AFM.

You will then require another remap later down the track and by that time you may as well have bought a pfc.

ECU remaps are only worth it if all mods are done and you will only require 1 tune. If you are doing mods in stages with multiple remaps then the pfc is the only and cheapest way to go.

The absolute cheapest way around it. Grab a second hand SAFC for a couple hundred, wire it in yourself, select 4 (z32) in 2 (std rb) out (from memory) start it and drive it off.

A stock afm is worth around $80-$100. You can use either an R32 or R33 S1 AFM.

Unless you run an safc that converts the signal back to that of what the stock afm would read.

I have a SAFC II, does this mean I can install a z32 AFM ? i always thought u need an aftermarket ecu for this..

why do you want to change AFMs?

there's no power gain to be had from a z32 AFM...

this i simply don't understand

so you can run more boost, and be able to get over 230-240rwkw.. dont think this can be achieved with the stock afm..

WazR32GTSt

because my stock is stuffed..the car runs like shit sometimes and really nice at other times..

so instead of getting a stock ecu.. i thought it would be better to get a Z32 to power proof it..

Get your old one fixed...its cheaper and less fuss

:D

Yes you can run a Z32 with your SAFC. There's an option that allows you to select HW4 IN HW2 OUT. Read the manual its something along those lines.

All this essentially does as I stated before is modify the Z32's afm signal to read what the stock afm would have under those airflow conditions.

So no the Z32 with an SAFC won't allow you to make more power due to having a higher airflow/volt ceiling.

You will need a remap or pfc for that one. :D

Power proof to me means to me; if you have to buy another afm why waste the money on a stock item when you can buy a z32 now and get it working with what you have; later on down the track when you throw a bigger turbo on with an ecu remap or pfc its power proofed. :yes:

im aware that i wont get anymore power, the reason id get one is to resolve my fuel cut issue with the stock afm.. i cant boost any higher then 16psi..

Have another read of my post. If you are getting a fuel cut issue with the stock afm the Z32 isn't going to do sh*t IF you don't remap the ecu or run a PFC/aftermarket ecu.

As I said... The SAFC.

HW4 IN (Z32)

Convert to

HW2 OUT (RB AFM)

This essentially modifies the signal back to what it would read at that airflow level with the stock afm. SO you WILL NOT get around the fuel cut issue at 16psi.

ive been told by a tuner that i can get around it with the SAFC II, this is why i was asking..

Poviding there is enough scope you could set the afm to HW2 IN HW2 Out. This won't manipulate the afm's signal and cause the car to run mega lean across the board.

IF you were to richen it up via the safc it may give you a tad more head room but do remember as you use lesser load points the ign. values used are also higher. As a result its a receipt for detonation and a broken motor.

If you do go ahead with this be sure to throw it on the dyno when summer hits to ensure its not detonating as it will be very very close to the edge of detonation.

I wasn't going to mention you could do this and put the idea in to ppls heads as its a very bodgy way to squeeze a little more power out of the stock ecu. I believe this method to squeeze a little more out of their stock ecu has been covered some time ago. I also believe the bloke had rather dissapointing results. But its all setup dependant.

No doubt if you were to fit up an ITC and an adj. fuel pressure some decent gains could be made.

For the sake of slightly under $1000 for a pfc is it really worth the risk.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
