S AFC II for me... still waiting to get it tuned. Now that I know AEM has a universal EMS I might plan on going that route later on

Are there any HKS authroized dealers here in Florida that could do the tuning? That could be an easier route then the AEM universal setup.

I assume that you are running a manual transmission ?

Sucks for me because I am still using the auto box otherwise I would have already had the AEM ECU in mine. It would be a nightmare to try and get the autobox mapped with the AEM (if it could be done at all).

As far as AEM coming out with a universal unit. You do not have to wait, there has been a version available for the 1JZ for some time now.

Nah, got_trd has an auto tranny. Right Chino?!

Yeah I have a HKS fcon vpro with no harness
But I am no longer going to take that route. I am thinking of PFC because I can tune it myself. I currently have a s-afc in the car. Does anyone know if I can get away with using that when I go single until I get the PFC? I know the USDM 2jz guys use the s-afc coupled with a VPC. But to my understanding of the VPC we dont need it since we are maf-less.

So does anybody on here have experience with a single turbo 1jz, s-afc and bigger injectors like 550s?

I imagine you could get 400-450whp out of this safely

Also anybody running emanage on there 1j? I have alot of experience tuning those

Gamer

In that case he is limited to a piggyback ecu, the S AFC II will suffice, a step up would be the greddy e-manage, then the FCON S.

The manual tranny guys have a vast choice...

Listing my choices if I had a manual it would be:

HKS FCON V Pro
AEM ECU
Apexi Power FC

There others to choose from as well....

Gamer

You should be ok, you might get slight det problems if not tuned correctly. Run a cold plug with an 8 rating as well.

One of the UK guys running his stock turbos at 18psi (fmic/440's/e-manage) had some slight det problems but I think they tuned it out.

yeah emanage would be a huge step up from afc because of timing control and higher resolution fuel control. Any members on here with experience with either the afc or emanage on single turbo app?

GRIFFIN TT

ahh thanks but no single turbo guys huh?
yeah 18psi is a bit much on those stock heat snails and he probably was only controling fuel if he got detonation

Gamer

Found one... Forgot about a UK friend who has just had a single kit put on, he is running an e-manage..

No reports of any issues with that and the single..

You can read about it here...

JZZ30 single kit

The pictures of his set-up are not showing though...

I was researching this yesterday actually. Piggy backs like the PFC, SAFC, AVCR can only push the stock limits so far. Here is our problem. Our stock injectors run at 340cc and it will be extremely difficult and/or impossible to get the piggy backs to double the injector pulse....say to 650cc. The piggy back systems might be able to push our injectors about 75% more than they should, but that is about it.

EDIT: this is assuming that you have aftermarket injectors on already. The piggy backs have their limits. Hence, why everyone decides to spend the money on the standalones.

I have all my parts, but just one major one missing. The standalone. I'm waiting for my HKS FCON to arrive. I might even have to do a custom harness

got_trd

No EMS on the Auto?? That blows. Im not all that familiar w/ the EMS set-ups yet because im not ready for it. Ill look into that though.

GRIFFIN TT

Thanks gamer
looks like he is just using the emanage and a boostcontroller

You can adequetly run a s-afc with 550's. I know this for fact. That will hold you up to 500whp. Auto tranny cant go past that so my goal is 450whp for now. So fueling is not really a issue unless you are running a manual and going for the big HP.

This is why intially I want to go piggy. Only problem with afc is lack of ign control. So you will have to run the car pretty rich and I dont know how good the knock control is on the oem ecu.

Gamer

The FCON S would be the best bet for your goals. It controls the fuel/air and the ign control.

I should add that I use the AEM C2DI to enhance the spark.
