Fuel Management + Boost Control

[matt0941]

If you have, or plan on purchasing a fuel management/boost controller system for your KA24DE-T please post your setup. Also be sure to include any information that you find valid (Turbo, etc.).

SDS em-2 standalone fuel only with MSD 6btm to retard ignition timing- adjustble for every lb of boostim using msd 50 lb injectors in Jim Wolf fuel rail

I plan on getting Greddy Profec Bthis is on turbo ka24de: 60 trim t04e compressor .63 ar t3 housing stage 5 wheel

[Maeda]

greddy emanage and profec e-01!

does fuel, bigger injectors, ignition timing, boost, and is a boost gauge when you get both of them together...

nice lcd screen too o.O

good luck finding a place to hide that thing though.. im currently looking for a stealth location to put mine =\

[WDRacing]

Instead of building my own 240, since I'm buying a GTR instead, I'm going to be building GirlracerS14's.

Here's my plan thus far...

She already has the bottom end built with forged goodies. She has a TO4E turbine kit already installed, not sure of the trim. So I'll be using a JWT ECU with a Cobra MAF and 72lb injectors. I'll probably use the HKS SAFR for minor A/F adjustments, atleast for the off boost rpm range. I'll also be the SMC Alcohol Injection Kit for instances when the boost is dialed up to 2 Bar.

I'll also be installing the NOS Direct Port NosZle, tuned to 100 hp.

The car should be one of the quickest in the country.

Sweetness WD. Thanks to others for posting, good variety. I am trying to decide between the following for my KA-T (T3/T04E):--------------------------HKS S-AFR – 11 points, 50rpm increments between 650 and 8000 $300HKS EVC – Boost controller $600--------------------------Apexi S-AFC ii – 12 points, +50% or –50% adjustability for each point, can set 2 predetermined maps EDIT: $300Apexi AVC-R – Boost controller $630----------------------------Greddy e-manage – 5 points, +20% or –20% adjustability for each point $320Greddy e-01 – Boost controller, e-manage controller, display $500----------------------------

Along with each I will be using a JWT ECU as well as either a Cobra or Z32 MAF (not sure which one).

[Maeda]

if you pair the e-manage with the profec e-01 you get 16 points btw

[matt0941]

I did not know that, thanks for the info. Do you think that the %20 is weak or does not really have an affect. I don't know this kind of stuff because I have never really turned a car.

This is from greddy's website

e-Manage is an inexpensive programmable fuel management system that allows you to properly tune your factory fuel system, without having to change the entire factory ECU system to an expensive "stand-alone" unit. The e-Manage system is a universal "piggy-back" type unit, which taps into most factory ECU wiring and it still utilizes the existing sensors. Basic functions will allow the user to slightly alter factory injector duty-cycle(± 20% at 5 preset RPM points), by intercepting and altering airflow or MAP sensor signals. For VTEC cars you can adjust the VTEC shift point.

Additional features that are built into the system, but are only accessible though the use of our PC-Windows based "e-Manage Support Tool" communication software (Please see our Authorized GReddy Support Dealers for more information) are a 16x16 Airflow Adjustmemt Map, Larger Main Injector correction adjustment, Upgrade Air Flow Meter adjustment, Boost Limiter Cut, Anti-engine Stall, VTEC-fuel adjustment, Real-time Map Trace, Real-time Display, Real-time Communication, and basic Data-logging.

With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 Injector duty cycle Map and the Controls for adding up to 2 Addional Sub-injectors. If the "Optional Ignition Harrness" and the software is used the unit has the ability to control a 16x16 Ignition Timing Map. All of the above Maps can also be Map-traced in Real-time as well. If the factory range of Map or Airflow meter is surpassed, you can incorperate our "Optional GReddy Pressure Sensor and Pressue Harness" to set larger scales of ajustment.

Now if you look at the second pharagraph you will see it says with a computer it has a " Larger Main Injector correction adjustment" so i assume this will be larger than 20%

edit- by with a computer i meant with there software. The "PC-Windows based "e-Manage Support Tool" communication software "

What i like about the greddy's set up is the ignition control, but I like how the safc 2 will tell you if you knock.

[Bryson]

Well for my fuel management I am going with the e-manage, profec B, and a laptop. For the price of the e-manage and e-01 (around 800-900) I will now be getting some I can useoutside the car and has a real screen. e-manage /w support tool (350-400)laptop (345 shipped)profec B (200-300)

as you can see it comes out almost the same as the e-manage/e-01 and this way you end up with something much more useful.

well there you have my .02

Thats a little overkill. Why not just go standalone from the start. With the prices for a JWT ECU, and a pair of the electronics above, you are well into the price of a full standalone.

Those prices are kinda steep, eh? The Apexi S-AFC II can be had for around $320 on Ebay for example...

[matt0941]

I suppose, but I don't know much about tuning and dont have the cash to go somewhere where they can tune my standalone with every minute modification I do. If I am wrong please inquire I would love to save cash =).

Pornflakes: Good 2 know, I just compiled that list quickly from internet shops.

Bryson: Very good point, but say that you did go that route. Are you missing out on any options by going laptop+profecB than you would have with the e-01? Also, was the $140 laptop cable for the greddy e-manage (overpriced) included in your pricing?

To others: I plan on making a compilation of many applicable fuel management + boost controller systems available for the KA-T project. I will probably finish compiling one once I make *MY* decision.

[Bryson]

MATT0941. I can't say yet from experience ( can soon enough though get my 6k to work with in like a week.) But from what I've read and compared... no, going with1)e-manage2)profecB3)laptopwill not lose any features, infact I think you gain by having a much larger and easier to read screen with a mouse and keyboard instead of a little crappy green/black display and a remote control.

As far as I can tell what makes the E-01 so special is that it unlocks the laptop features and can datalog different engine statistics.

The e-manage unit is what really logs it, the e-01 can just display it... so ya after posting this long *** thing, I am basically saying no features are lost.

Ya some of my price estimates are high because sometimes I see them go lower on ebay. Sometimes not I haven't been able to find a STORE that sells it for anything cheaper than 400 or so with the laptop connecter

[syka24et]

--------------------------Apexi S-AFC ii – 12 points, +50% or –50% adjustability for each point, can set 2 predetermined maps $660Apexi AVC-R – Boost controller $630----------------------------

-------------------------

Safc is on ebay for 260 buy it now brand new!

[WDRacing]

The thing is fella's, Matt doesn't have the time or the experience to tune a standalone. So the HKS SAFR is a great idea to start with. Its only a few hundred bucks. That gives him some room with cash for other things like B/C and knock sensor. If he spends 350 on a SAFR, how is it cheaper for him to go standalone?? I'm not done talking him into what boost controller to buy yet either. I don't wanna see him waste his money on the ones he listed when you can have a perfectly good dual stg with money left over to buy all the cool leds your heart desires...lol. Sorry Matt, couldn't resist.

WD

[matt0941]

No problem WD. I am surprised that you would still be loyal with the S-AFR with the S-AFCII out now, but you probably have your reasons.

As for whiteS1498's comment:Quote »Why not just go standalone from the start[/quote] I think he was just saying that with the money that I spent upgrading the MAF, and ECU, then an extra hunk of cash for the piggyback system as well as a boost controller I would save cash going standalone. I doubt he knew that I can't tune that well =/.

But WD, you kinda left me hanging there, by saying what NOT to get! I value everyone's opinions (yours more though) but it is hard to get past this stage in my turbo list compilation when I have heard:

Go SAFR Get the new SAFC!Get the e-manage with the awsome e-01Get the e-manage and save cash with the laptop!

Hard to make some decisions here. But I guess what I will take the next hour to do or so is read between the minute pros and cons of each option and pick what is best for me. Thanks

[WDRacing]

Well, i'm nor sure if you can upgrade your MAF without a standalone or ECU rewrite like JWT. I assumed you were keeping the stock MAF for now and just upgrading injectors. The reason I stick with SAFR is because I'm an HKS supporter, always will be. The Emanage seems like a good thing as well though. I have no data on that at all though.

As far as what I wouldn't do, I wouldn't buy any of those B/C's you mentioned, way to much cash for what you get.

WD

[matt0941]

Go non-electronic B/C?

As for the MAF I am pretty sure that the Z32 MAF does not require a JWT ECU rewrite while with the Cobra MAF does.

[WDRacing]

Yeppers, i'll take a good ole dualstg manual B/C every time...plus with the money you save, buy an alky injection kit. I love making perfect sense...

WD

[matt0941]

Hehe you and your damn alcohol.

:alcoholic <----- guess who

As for the piggyback system, how many people using one have upgraded the ECU?

[Maeda]

i dont understand why youd want an upgraded ecu unless you need it to baseline #'s for huge injectors out of the range of a piggyback system...

id save the money and just stick with a piggyback system no ecu...

[C-Kwik]

A JWT ECU removes the speed limiter and raises the rev limit.

[Maeda]

ahh thank you for clearing that up...

personally im going without it because.... i hope never need to go past the stock rev limit and speed limit...

[matt0941]

i hope never need to go past the stock rev limit and speed limit...

:Werd

As for what I am going to choose for my fuel management: I simply still do not know.

What would be your guys main reasons between picking between the ones I listed?

I was thinking (if you switched the HKS electronic B/C with a manual like WD suggested):

Go HKS because of $ savingsGo Apexi because of dual fuel mapsGo E-manage + e-01/labtop (laptop?) for included boost control

P.S. If you are all about the bling bling Apexi will be releasing a limited number of black/white color scheme S-AFCII's (apposed to grey/blue) they should be extremely hard to obtain though.

[midnight brother]

What about considering SDS

Regardless of everything discussed on this thread, if I were to do it all over again, I'd choose:

72LB injectors ($400)JWT ECU (more than just the rev and speed limiter modified...trust me) ($595)Apexi S-AFC II ($300)Apexi AVC-R ($400)

Can't go wrong with it... I know it adds up, but after the bitterness of the price goes away....the sweetness remains.

i'm thinking about going this route for my SRswap. it seems more user friendly. do you really need to get a JWT ECU along with an upgraded MAF? also, what are 72lb injectors equivalent to in terms of cc?

[hannibal]

You don't have to get a upgraded MAF to use the JWT ECU. But if you upgrade your MAF, you will need the JWT ECU(or a standalone) to read the new MAF properly.

Injectors72 lbs/min = 756 cc/min

the conversion formula is:cc = lbs x 10.5

Jay

[matt0941]

if you upgrade your MAF, you will need the JWT ECU(or a standalone) to read the new MAF properly.

Not for a Z32 MAFS. In addition, why do you want to go with 72lb injectors? This number seems a bit large for the application (T3/T4), not saying you are wrong in doing so just curious.
