Hey Guys,

- I did you the search feature but i had couple questions to get an exact answer. I am putting on a APS Single Turbo Kit what do you guys think i will putting down at the wheels. I checked out APS site and it says 384rwhp not sure if that is true so if anyone has APS ST and got dyno'ed please share.

-Another thing is about gauges I was told just to get Boost and EGT. But now another shop is telling me to get Boost, EGT, Oil Pressure, and A/F UEGO. I'm not going to tune or data log so do i really need a UEGO ? Or anything else besides the Boost and EGT?

- I read a lot about UTEC and the FCON Pro. I just plan on installing the APS ST kit and just want about 380rwhp. Is that possible with the Piggy Back it comes with ? Do you guys recommend to still get a Tune if i plan on just using the Piggy Back and happy with whatever horsepower i got from the factory?

Thanks for the help.

 

boost
egt
a/f gauges are all good. I would also get a fuel pressure.


Yes, You should get it tuned by somewhere like GT Motorsports.

The reason you want the a/f gauge is to keep an eye on the a/f ratio to make sure it doesnt get lean or overly rich.

 

I wouldn't bother with the EGT gauge, its a crude method of showing you a rich or lean condition.

Now that widebands can be bought for $300 new and $200 used, theres no reason to buy an EGT gauge.

 

Liar

 

For your power goals, you will just need the unichip. Your tuner should be able to get that tuned to around 380-400whp.

You already have oil pressure, why do you want another one?
Two mandatory gauges would be wideband and boost. I'm partial to the Innovate wideband.

 

A G35 doesn't have oil pressure...?

 

Forgot to mention this is for a G35 Coupe 2003 6mt

 

So Boost, EGT, Oil Pressure, and AEM UEGO good ? gauges?

 

Everyone has seemed to wrap it up. But I would recommend getting a Utec and more personal tune.

Has anyone heard about if the Utec has came out with there updated version with the 12x12 resolution, instead of the 10? Which is still great. They released this info at SEMA for spring release. But we all know how that goes.

 

do yourself a favour and leave room for growth... sure, you'll be elated with 380rwhp at first...but, give it a few months and that will seem slow to you... my suggestion, get a UTEC unless you have the money for an FCON V-Pro... the UTEC will give you room for growth upwards to around 550rwhp (not that you'll EVER ascertain that with the APS single...but, it would be one less thing to buy if you went twins)

as far as gauges go, there is NO NEED for the EGT... it's a waste of money as you won't be running much hotter temps than stock... go with boost, A/F (preferably a good NTK type...if not, i recommend the Innovate...AEM FTL.) fuel pressure and oil pressure... these are the items that you always want to keep an eye on... they will alert you to problems that can be catastrophic...

also, research the kit that you're buying and learn its idiocyncracies... the APS single is known for boost spikes, so this is a PERFECT reason to get a boost gauge... remember, power is in the details... (where have i heard that before? )

so, to recap...def UTEC or FCON...(unichip = crap)...boost, A/F, oil and fuel pressure gauges and you're all set...

 

Didnt know you had a G35. If you're running 8-10psi, there is absolutely no need to "grow" with an Fcon on utec AT THIS POINT. Unichip works great at that PSI, I have no idea why the above poster would say it's crap (for your needs). Alot of forum BS and hearsay I suspect. Now, if you're NOT getting the complete APS single turbo setup (tuner kit?), and can chose and EMS, then I would not get a unichip. Gauges, I would go with boost, a wideband, and oil pressure. Oil temp is a good idea, but fuel pressure would be "optional" if you don't want to go all gauge crazy. Just monitor your A/F's.

 

that post was 75.7% BS, 21.3% arrogance 2.4% actual usefull information, and the remaining 0.6% filler.

If you actually knew as much as you think you did about the APS single you would know that the unichip is fine. I ran it and it works just fine. Controls timing, fuel, and boost. For the boost levels and fuel sytem he will be running on a stock motor, the unichip will be work great. If he decides to go for more power with the single, or a twin setup he will be looking into a more advanced EMS. Until that point, there really isn't a need for anything more advanced.

Your comment about the single being known for boost spikes? Not to my knowledge it isn't. I know it is sensitive to backpressure. If anything, most are seeing boost tapering at the upper RPMS. As a result, you basically must run the APS exhaust with it. If properly set up, boost issues will not be a problem with this kit. And I am curious, what will running a boost gauge do to actually prevent or resolve something like a boost spike? A better suggestion would be to recommend a reputable APS shop install the kit with the APS exhaust and have it custom load based dyno tuned and have the boost properly dialed in.

Just one more thing; when did you become so educated on the potential of the single? We have seen maybe 2 attempts at higher HP with the single. True, twins have much more potential, but mid 500s is attainable with a proper build.

 

Thanks for the help guys. So this is what i decided on

- Defi Bf Boost
- Defi Bf Oil Press
- Defi Bf Fuel Pres
- Innovate DX-16 A/F ...... No EGT cause everyone says Useless.

 

Make sure you get the aps st exhaust and aps tall boy before you get tuned. My aps kit only made 330 whp out of the box. maybe you will have better luck though.

 

I have the RS*R Exhaust and Spacer so i'm hoping this will be good the guys @ GTM said i should make a good amount of power

 

They did mine as well. Hopefully you get some better numbers than me. Goodluck.

 

What setup did you have like exhaust ? Spacer?

 

wow. that's all i can say...

do some research on the APS single kit... see why it's dropped about 3k in price since coming out... find out what other members have experienced with it... ask tuners... most will tell you EXACTLY what i said...that the kit is prone to boost spikes... and in what part of my post did i say that a boost gauge will arrest boost spikes or prevent them?? i didn't... but, let's use some common sense here and realize that boost gauge will TELL you if there are boost spikes... if you set your boost at say 9psi and your peak boost on the controller shows you at 12psi, there's your spike...and now you know about it... some people have very little logic...

as far as unichip goes, i'm not bashing it, but it's not nearly as granular with control across the power band as say a UTEC...and no where near as capable as the FCON... i'm no tuner, but i know a few of the most reputable ones and they will tell you all day long that unichip = crap... so, there, i said it again...unichip = crap in comparison... all of you guys nut-hugging unichip aren't doing the OP any favours... everyone wants more power in the end and you should prepare for it up front... ALWAYS give yourself room for growth... you wouldn't recommend HKS exhaust to a guy who wants to some day go FI, would you?

if you think that any single turbo kit on the market is capable of making mid fives, you're cracked... none of them can produce or sustain the boost level needed... the turbo isn't enough to hold max PSI to redline... it may be possible with a much larger turbo, but not with any kit that comes pre-packaged... you call my post bs... i call yours lack of education...

 

Nice job on your "research." Price drop due to forum members bad experiences? LOL dude. Seriously, LOL.

Take the OP's situation in CONTEXT. The unichip is MORE then capable in achieving what needs to be done for his particular needs. I know plenty of APS ST guys who have run the unichip with absolutely no problems on stock boost. It's silly to recommend a 3k EMS when it is not needed. The APS ST kit is a complete system, why throw on FCON and blow more money now when it's not needed? Your advice is simply horrible. I'm tired of everyone jumping on fcon when they don't look at the big picture. Ask your tuner friends if they personally would run a fcon on APS ST, on stock boost. Seriously, ask and post what they say.

Now if he gets a "tuner kit" per se, that's a different story. When he's READY for more power, engine build, etc... THEN he should upgrade the EMS, until then... he'll be FINE with the unichip. I don't know why you are thinking some of us are nut hugging the unichip, when the ironic thing is Zivman and I are NOT using it. Zivman has FCON, I have utec, and will be upgrading to fcon later this summer.

^ sounds like a contradiction in your entire argument? Mid-5's are capable. But if what you're saying is true, wouldn't this be ANOTHER reason why NOT to get fcon?

I hit 500 and will be aiming for more after a few engine issues are resolved. There are also a few other ST owners on the forums with engine builds, or engine builds in progress that will be hitting those numbers. What makes you think it's not possible? How do you know this? Did you own a single turbo at some point at maxed out mid-400's or something?

 

Sounds like a good plan. You'll also need the control unit for the BF series. I prefer stand alone gauges, but the BF series are great.
