Can A Stock DE run with a z32 maf?

[Ezzo]

Like the title,

Basically the MAF craped out on me today in my DE. Since i'm building tword a KA-T can I replace it with the z32, Supra or Cobra MAF now? so I don't have to waste money on a stock maf in the mean time?

I'm just not clear on if it needs the posetive pressure of a turbo to send the correct signals to the ECU or if it will work just like the maf I have but along a wider read range?

[gaehrings13]

You need something to get that to work like a safc, or a emanage even standalone but It will not work just by connecting it.

[Ezzo]

ok all I really needed to know, I'll try to find a maf from the junk yard sometime this week then. Thanks.

[Chezedik]

It will idle, and will not throw a code, but it won't run that way. With an SAFC, eManage, or tuned ECU you should be good.

[silvia2slow]

my buddy put a z32 on his without doing anything else and he drives it everyday. he has had for about 2 months and no problems so far.

[Ezzo]

Well I can see where everyone is coming from, like a wideband 02 wont work with a stock ECU so it makes sense that a wider reading MAF wouldn't ither. I might just invest in the SAFC now and use the MAF. Ive got the week to figure out what to do so I'll search a little bit more on the topic. If I don't come up with a result i'll just get another stock MAF. I was planning on getting a SAFC2 or NEO soon so I could get used to it before I go KA-T. It's just a little extra money this month than I was expecting lol I just finished the cooling system that kicked me hard in the nuts, before that was the brakes. so my funding is a bit low due to unforeseeable circumstances.

[Chezedik]

You can get emanage for the same price, and if you get it with the ignition harness, and buy yourself a car-hacker cable, you can also control timing with it.

[S13FX]

I also recommend getting a Cobra, or Supra vaf right off the bat since it's easier to tune with.

[Ezzo]

Don't I need a laptop to interface with emanage? I was also under the impression that it doesn't come with any pre-settings for the KA24DE?

[Chezedik]

When you set the knobs to 2-0-6 you are set for KA. There will be no required pre-settings, as it is a piggyback and so it does not require a base tune to operate. You just change your injector setting and MAF setting under 'Parameters' and then select which tables you would like to control.

Yes, you will need a laptop or one hell of a long USB cable.

[S13FX]

I don't know why but I can just imagine him sitting at home on the computer yelling out the window to some one. "IS IT WORKING NOW"

HAHA

[Chezedik]

Imagine trying to datalog.

[Edub1]

The stock MAF is good for nearly 300HP - about 270 most would say. The Z32 requires tuning in order to run right. If you don't plan on over 270HP stick with the stock MAF.

[Chezedik]

I have a couple for sale if you would like, 40 shipped.

[Ezzo]

Thanks for the offer I would have grabed one off you but I got a junk yard special for 10$ put it in today and works fine. If it craps out on me I'll letcha know lol. My ka-t goal is only a healthy and reliable 250whp. Nothing too crazy just enough to enhance the feel and make for a fun ride.

I didn't know if emanage came with a set of analog controls for those who don't have laptops. I use a G4 powerbook only my desktop is windows based so I guess it's yelling out the window for me ^.~. Unless greddy has hoped on the mac tip also then I would be in business!

How user friendly is emanage? I'm pretty new to piggy backs and standalones so i'll need something with a decent learning curve for me. I'm mechanicly inclined and 9 times out of 10 I can troubleshoot on my own. I'm just usually worried about how implyed peoples skill levels are when they say "It's real easy!"

[480sx]

If you want something easy go with a SAFC2, man you cant beat that. Also that works well for your HP goals, and could control an upgraded MAF.

I have only HEARD that the Greddy unit is a pain to learn on. Of course the more experienced guys are baffled by this, but to each his own.

Again, safc2 is such a sweet learning tool, i would always recommend starting with one and a wideband for your first steps into tuning. Also, because its so popular you can always get help with it. Later down the line you can feel good when your helping someone out with what might be the most popular entry level tuning device ever made.

[S13FX]

Let me just say this

SAFC and J&S Safeguard. You have the ultimate tuning tool. Unless you plan on getting bigger then 550cc injectors. In which case thats above 400rwhp. And thats some serious power tight there. The J&S Safeguard is a great tool period however so yah.

[Chezedik]

Emanage does have knobs on the outside to control it like the original SAFC, but you really can't use any of the enhanced features that way, and should get the cable. It's environment isn't too bad, but it isn't as easy as making 5 rpm adjustments either. It is a 16x16 table in most cases to make your adjustments, and should take a little longer to tune. But it will also be a more well rounded tune with less chance of *gasp* blowing your motor on decel.

[Craving4Boost]

S13FX - I've been waiting for a while for more people to test out the J&S safeguard....do you know anyone doing it with a KA or 240 in general? I know it should be used the same with most cars but just curious.

[S13FX]

Actually I just finished a KA-ET for a friend of mine, we ordered the J&S Safeguard Ultimate with the boost sensing option. Right now we are using a chipped ROM tune on it.

My plan is to take his tune return the timing map to stock, then hook up the J&S Safeguard, run 93 octane run aabout 10 psi. And see what it does. We will also be using the knock light option with it to monitor. Im guessing from something like this at 10psi. We will be well over 300rwhp, Since it will allow us to run border line timing maps.

And since the J&S Uses a sonar type knock sensor so it virtual detects any pinging before it even happens, and only knock timing down on that cylinder. So this should be an awesome toy.

[Chezedik]

I must admit, it is very impressive, but so expensive. Can the dual monitor be used w/o the Safeguard, do you know?

[S13FX]

Im not sure what you mean by dual monitor?

[Chezedik]

It's a gauge that they make?

[S13FX]

Oh yes yes, it is a gauge it displays which cylinder it detected knock in and shows how much retard it's applying.

[Chezedik]

Sure, but it actually applies the retard based on the knock sensor input, right? Not the level of detonation that exists?

[S13FX]

The device comes with a specialized type knock sensor that utilizes sonar. The creator of the J&S Safeguard used to be some type of a Sonar Engineer in the air force. It also takes into consideration how much ping it detects, and the boost level your at.

This thing is pretty damn intelligent, and takes a lot of different things into consideration. Im going to dig up some articles and make it it's own thread if anyone else is interested in this thing.

[Chezedik]

It said something that in a power only situation it only used the stocker. It used the sonar style in cruise, if I read correctly.

[Ezzo]

Well I want something that has a decent learning curve and a bit of a safety net so that I don't blow up my engine as soon as I hook it up lol. But I also don't want something that I will outgrow quickly. I'll check by greddy's site and see if I can get more information on there software. I imagine I only need it hooked up for base tuning it doesn't have to be connected at all times rite?

I also like the knock detector but doesn't the ka already have a stock knock detector? will ither of them interface with the emanage or will I have to run them seperate. Also if it detects a knock can emanage or the detector unit change my timing on the fly to correct for the detonation?

[Chezedik]

Just go to MOHDparts.com and you should be able to download a copy of the software to play with. I would guess that Ultimate will probably allow knock sensor input for logging, but Blue/Gold will not. You could put it in and log the voltage as Airflow 2, it would be erratic, but could be used to check for peaks on the graph.

[Ezzo]

Thanks for the link, I downloaded the ultimate one because it was the only full version not update but it asked for a seriel number so I couldent install lol. I'm pretty sold on the emanage but I would like to mess with the software before I buy it. Additionally if those are the full programs will I just need a usb cord to interface with the unit? so I don't have to buy the 130$ connectivity kit
