Does The Aac Valve Flow Enough To Run Antilag?

I'm planning on running antilag on my R32 gtst targa car. I'm running a RB26 throttle setup (using the RB26 injector plate, through to plenum), will the aac valve flow enough air on closed throttle to run antilag properly, or will i have to prop the throttles open/run kicker soleniod/run bigger aac valve?

That thread is useless. This guy is using it for a Targa car and is asking a legit question! I have only used Group N on my car so I cannot help.. Interested in knowing what you find out though

So did you have the throttle jamed a certain % open, or use a throttle kicker?

I'm running a Haltech Platinum Sport 2000

Yeah i opened the throttle to 15% and i use the vipec ecu with cycle idle

The AAC doesn't allow air enough for proper anti lag - your talking 40degrees retard to get boost at idle plus you want at least 2000-2500rpm if not more. I would be selecting another ecu as well - something that has a proven track record in group N - like Autronic or Motec. You really want closed loop boost control as well - to limit overboost. A "throttle kicker" maybe the best way as you only need a small change in tps to get a large change in airflow when you have 6 tb's.

I'm not expecting boost at idle, just trying to bring to take a chunk of lag out of the poor rb20. I'll give it a crack with the aac first, who knows may be surprised. At the end of the day it's pretty easy to prop the throttles open with the rb26 adjustible linkages.

I'm sure the Haltech will be fine, it has closed loop boost, all the antilag settings for antilag retard, fuel, rotational idle...ect. Alot of cars down here (tassie) are running Haltech. I'd rather stab myself in the face than use the Autronic software, and i'm not morgaging my house for a motec.

Hey I dont mean to seem like I am hijacking here. But to get a bigger IAC valve, what would you get?

My stock IAC doesnt have anywhere to go on the current plenum I have. Was wondering if I got a different IAC (brand, shape, size etc), is there one that would just would work with the stock wiring loom. Granted I may have to wire a different plug onto the end of it.

Also is there one that will simply attach via a tube so I can connect it to the plenum via a hose instead of having to get the plenum cut and thread tapped into it to bolt it on?

Sorry about the slight hijacking.

i had this issue so i used a pice of 6mm alloy and made a plate for the alve to bolt onto then i got a 5/8 weld on fitting welded on to the 6mm plate. walla. i can mount the idle valve where ever. its just a matter of plumbing it in.

Ahh ok yeh that sounds like a good idea :no: Should give that a go.

Cheers

      This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.

      Yeah so when you turn key to IGN the fuel pump should run for a few seconds. If you find the fuel pump relay (and have a multimeter, and a second person) to can check the relay inputs.  One trigger pin should be either fully earthed  The other trigger pin should get 12v from the ECU for say 3 seconds when you turn key to IGN, and at all times that key is at START (note, I said this from memory, it may be the other way around, ie one pin always has IGN 12v and the earth has continuity to earth when you turn the key) One Pin should have a good battery voltage The last pin goes to the fuel pump + Also note that if the power to the relay is good, and the relay is working, it is worth checking the pump has a good earth too. There is a computer in the standard system that increases the earth resistance to slow down the pump when not required, pretty old school and it may have failed

      All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible

      Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.

      They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox) They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox)
