JWT or Emanagement?

[ckamc]

emanagement is like 300 and jwt ecu is like 550... but what are the advantages and disadvantages of going emanagement instead of JWT ecu? Im looking for a cheap ECU upgrade and i was intrested in the apexi sfac untill i read up on it more and desided it wasnt good for my intrests.

so yeah which should i go for?

[virus77]

they are both different systems. If you like tuning yourself and are up to the challenge go with the emanage, I use it and its a pretty cool system but it cost more than 300 when you get the essential add-ons. If you are not to inclined in tuning or dont have much experiance, jwt is a nice route.

[:: orion ::]

And research a little on the E-manage with a KA-T...I've read there are problems making part-throttle corrections to timing...the ECU always overides.

Someone else with E-manage experience may chime in...

Hmm.. I havent noticed any part throttle problems but I use the boost sensor to tune and not MAFS so it could be contributed to that. Either way I dont even recomend getting an Emanage if you dont get the goodies with it.

sorry if this is thread hijackin but can the emanage save tunes or at least use a pc to save tunes? like say i would like a daily driver tune and a race tune, would the emanage do it?

[ckamc]

what would u consider an accessory that comes with emanagement? I am acually going to send it into a local shop for them to tune it with the dyno.

I tune it with the profec eo-1 so i have 3 different "tunes" that it can save and load. it goes on a memory stick in the profec. I would imaging with a laptop/pc you can have as many tunes as you like on the hard drive/floppy/cd.

But on my daily drive i have it tuned up to 15 psi on one map. I just adjust my boost and its tuned anywhere from 4-15 psi on the same map. Then i have a map which I am going to use with my alcohol injection when I get around to it.

-The Ignition harness, if you buy a ignition harness it has enough wire to wire the injector harness so you only need the igntion harness and you get both. This allow tuning of fuel using injector pulsewidth and it lets you adjust ignition timing.

-presure sesnwor with harness ( I use my profec eo-1 for this so I didnt need it but its a nice option) This does a few things1) It allow you to tune based on boost pressure so its real simple. For example you put 2 psi boost i want to retard 1 degrees timing. then 4 psi of boost i want 2 degrees reatard and so on... It makes for simple effective tuning.2) it allows you to run over 250whp without upgrading the MAFS. So you dont have to buy a z32 mafs

These are the essential ones that i can remember right now. I enjoy tuning the car though so this stuff is interesting to me. JWT might be better if you are sending it to a dyno. Have them check the A/F and timing to see what numbers the jwt is making and either live with it, reflash it or get a SAFC to fine tune a bit. Like i said at first whichever ones suits your style they have both worked for people before.

The E-Manage is not bad per say. But I have had bad luck making power with it. For 1 I dont know how to tune... I got my afr's to 11.5 but I still dont like part throttle tuning or the idle... Infack by the time I got everything that went with E-Manage and the E-01 it cost about $1000 + all the time messing with it and trying to tune it.

I would say spend the extra $700 and go with AEM If that would have been a choice on my car the 1st time around I would hace done that. Within the next month I will order one and sell all my Greddy stuff. IE e01 and e-manage

[virus77]

I would go AEM aswell. I got mine all for a little over $500 profec and emanage, that why im running it but I like it. You dont need a profec though, which is the real expensice piece.

[Red-KAT]

I only got it to run my boost... Its also nice to watch and record the afr on. But yeah AEM... unless you just cant spend that much...

[nismo1003]

Can we make the tuning process to be sticky so that everyone can use it as a tuning refence?post map (use it as a base map with two smiliar setup) speically for those who uses the SAFC and the E-manage,

My vote goes for JWT..550, done. Although you need to have the right parts installed for his ECU maps, IE injectors and fuel pressure set correctly.

[Projex240]

JWT is simple plug and play, and if you want ot tinker with it, use an afc--you are still less with that than an emanage with all the *proper* add ons.AEM is great, the best out there. BUt just too damn expensive for the common tuner.SDS makes a nice alternative.

-Josh

[ckamc]

Ok so if you have the cash go AEM

If you are just going to have it tuned and set once and not bug with it for a while go JWT along with it being cheap *if you think 550 is cheap*

SAFC and E-management are the lowest on the list...

I guess that sums it up right?

[WDRacing]

The JWT and SAFCII is a very good combo in my opinion. If you want more options with better tuneability then save and go EMS.

I won't ever use the Emanage.

JWT uses stock fuel pressure normally. Just bear I mind If you go the JWT route , that you are going to have to wait. And wait some more. Apparently JWT is so busy that I've been waiting for my "RETUNE" since JUNE 9th 2004.

[KATwo40]

I've read consistently that Enthalpy mail order ROM tunes are better than JWT, with much less wait. Also, you can hire Enthalpy to come dyno tune it for you later for seriously fine tuning. End of story. But he won't mess with it if it's less than 550's, Z32 MAF and 300+ whp.

[ckamc]

but doesnt Enthalpy only do SR's and not KA-T's yet?

[turtl631]

He's working on the KA-T stuff. He said a while back that his first program was gonna be 550s, z32 mafs, t3/t4 type turbo. He also reported around 290 whp at 9 psi. I'd say contact him if you're interested...if he sees demand hes more likely to do more KA-T tunes.

[KATwo40]

Enthalpy is now doing rom tunes full time, both SR and KA-T. The last report said that he's even doing KA N/A applications. Contact him and get the details. He'll hook you up.

[hannibal]

Boost Designs now carries Enthalpy ECUs for $650 for S14 and $500 for S13.Do Enthalpy and JWT rewrite the ECU in the same basic way??

Ive always thought the Emanage would be my choice. But Ive heard about timing issues like Orion mentioned. Lately, Ive been thinking about JWT since its the simplest way to go. But I would still have to add a SAFC to make some real power and thats getting kinda pricely. WD, why dont you like the Emanage??

A dyno tuned Enthalpy ECU sounds really good now...

[D-UNIT]

Well I bought my car w/ a JWT NA stage 1 ecu. So I figured a $250 "retune" would be my best and fastest bet. What a slow horse. Even if I did want to go with Enthalpy , Jwt still has my ecu. SOL - sign of the times.

[WDRacing]

I HATE GREDDY......NOT TO MENTION ALL THE PROBLEMS PEOPLE HAVE HAD.

Does Enthalpy have a website?

[Red-KAT]

Yeah nothing worse in life then spending 5k Installing a Intercooler, Turbo Kit, and JIC 3" Ti exaust. Turning up the boost to 8psi and making a whole 180hp... WTF mate! They claim 220hp at 6psi...

EDIT: Thanks WD you just made me mad at my stupid car again! :P

[ckamc]

for everyone that has a ka24e Enthalpy does not do rom tuning so your stuck with JWT
