BTW- I believe its more like 200 alone just for the retune, the maf will most likely run you at least another 100, but probably a bit more.

last time i checked, it was about $600 for the initial reprogramming and $100 for each additional retune.

SAFCII can adjust for a Z32 maf.

BTW- I believe its more like 200 alone just for the retune, the maf will most likely run you at least another 100, but probably a bit more.

I was making a point for the emanage in comparison with the JWT ECU. Anyway, for the price of the SAFC II I would probably would be better off forking out some more dough and having the emanage with ignition timing.

And as dem said, it's more like $200 both.

[aleph1]

I coulda sworn it was 200 for a retune, bah, I guess I was off. Either way, I dont like the idea of something I cant tune myself whenever I want, even if JWT is plug and pray. My plan is to get the Crane cams ignition kit with BTM, AFC2 (with 370cc or 550cc injectors), and a Z32 maf (later)...I prefer to have a more modular setup...it kinda carries over from my music equipment preference.

If your paying $320 for an eManage you're getting ripped off. The support tool is like $120 and it doesn't take a genius to tune. all the other parts you listed you would need for both apps. Every setup I've seen has had a AFC and/or boost controller running with the JWT.

I just can't have my 240 sitting for 2-4weeks while I wait for a retune. This is my daily driver.

Here is a good site to get emanage stuff from. They also have the PDF's of the eManage guide and support tool guide. mohdparts emanage page

or be like me and get an extra ecu to send off so u have no downtime

[s14db]

Wouldn't your car run like crap till you got the good one back? or are you paying to have JWT tune both?

[TurboKA37]

hes saying find a ecu that u can send in to get reprogrammed and when you recieve the tuned ecu, install it along with the turbo kit. ur stock ecu is what you are using on the engine that is non-turbo while u are waiting for the the tuned ecu

[s14db]

I was talking after the install of the turbo. Subsequent tunings as you add more parts. The "$100 retune"

[huguetpj]

... even if JWT is plug and pray.

I read every thread after this one and I'm still laughing.

[Structure240sx]

this is how mine went. i put my turbo kit on my engine with the stock ecu and everything from the kit. now i bought 740cc injectors which are sittin in my room. i sent off a spare ecu to get tuned form them and a z32 maf that is on its way. so right now im driving with jsut a normal stage 1 nsport kit. oncei get my maf i can install the ecu and injectors. my engine is already built so i dont think i would really need a retune for anything unless i got some decent cams. u dont really need a retune for a different exhuast or intake

[huguetpj]

now i bought 740cc injectors which are sittin in my room.

Side fed, drop ins? How much where? Drop me a email so not to get off topic. [email protected]

They will also ship you out a chip with the new program on it. You pay $100 for the retune and $250 deposit on the chip. When the chip comes in the mail, you pop open your ECU, replace the chip on the daughterboard with the new chip. then you ship them the old chip back and they return your $250.

This way you can do it without any down time... They just hold on to your cash while you have their extra chip

-jeff

[TrunkMonkey]

the 240sx's ecu doesn't have a chip.

-demetrius

[huguetpj]

The E does, the DE does after the JWT retune... daughterboard remember.

But $250 deposit for a $10 (at most) chip???? WTF?

[Structure240sx]

but it was the work put into the chip that matters. its like buying a pair of $100 sneakers when the materials only cost $3. if everyone went around making their own shoes podaitry would be a good occupation to get into

and since i post already i got the injectors new but from a guy i sorta knew that already bought them. i got them for $425 shipped. they retail for about $550 from enjuku and phase2. they are nismo/tomei sidefeeds

That's what I'm saying...

I've said in the past and I'll repeat here for everyone:

This CHIP you guys are all talking is simply an EPROM. An EPROM is a "chip" that can store data, just like a hard drive. Think of it as a miniaturized hard drive.

The E ecu has a physical eprom. In fact, the part number is a 27C256 or variant. You pop that off the KA24E ecu, put it in an eprom reader, and read out its contents. That's exactly what I did. I have all the fuel maps and ignition maps sorted out for the KA24E ecu, but they haven't been confirmed because I have no KA24E equipped car to test it out on. Modifying the data is a matter of getting a hex editor software, going to the right location in the file, and editing the hex values. Erase the eprom under UV light, then pop it back in the programmer and burn the new data in.

Takes less than 10 mins to do if you have the modified data and the proper tools.

That's one of the reasons why I don't go to JWT for ecu retuning. I KNOW EXACTLY what they are doing to the ecus. I just don't know the modified data that's going into the eprom. The other reason is they use generic maps to program the eprom. By generic, I mean the maps they use have been developed for a certain maf/fuel injector setup and is richen'd a bit to avoid potential lawsuits.

Now, knowing that the eprom costs $5, labor takes 10 mins to perform and another hour to verify on a actual car, how would you guys feel about giving them $600 for an overly rich retune?

[C-Kwik]

It's like hand pinstriping. It's not the labor you pay for. Not even the materials. It's the talent.

Properly tuning any ECU for a car is not always very simple. A dyno shop that is really particular about tuning will add a throttle stop and make dyno runs at several throttle positions to optimize the fuel map for a wide range of throttle positions. Tuning at WOT is easy. Tuning at idle is easy. Tuning everything else in between takes time. The higher the resolution of the mapping, the more dyno runs you will need.

The Nissan ECU is a tuff cookie to crack. It's not a loose whore like the Hondas. JWT was the first and I still think only tuner to fully crack it. Most of the Japanese Nissan ecus either have piggy pack chips to richen it up or are custom jobs.

The JWT made sense for many years when Stand alone and piggyback ecus were ridiculously expensive. With the eManage being sub $300 and standalone units falling below a grand. The JWT is looking less logical.

Yes, it is difficult to crack because not very many people know both the mechanics of how an engine works and the electronics of how it works. Once you know how they both work, it's not difficult. I can guarantee you that if someone pays my salary for a month and provide me the test equipment, I'll tell you where all the fuel maps, ignition maps, maf table, speed limiter, rpm limiter, injector gain factor, etc, etc are in the data.

[s14db]

Read my post again.

I never said that all ECUs are hard to crack. In fact I made a comment on how easy Honda ECUs are to read. I was stating that Nissan ECUs are more complex than most. Jim Wolf even said they were encrypted.

I would love to be like GMs that can use LTunner to control all the ECU functions. But alas I don't think it will happen. I don't think we should be held up by one person’s proprietary technology. Other options besides the JWT ECU are becoming cheaper by the day and I think we should look at them.

I'd take that with a grain of salt...If you owned a monopoly on modifying ecu, would you want any of that information leaked out?

Like I said, I already cracked the KA24E ecu. The early model DE ecus aren't much different.

It's the OBD2 models that are complicated because the eprom is integrated within the microcontroller itself and there is no way to capture data going in and out of the chip, and that's why JWT don't do obd2 ecus.

Nissan ecus aren't more complex.. it just seems that way because there is not much information out there about this subject.

[aleph1]

Are you saying that the 91-94 240SXs have the removeable eprom??

[s14db]

Oh, I should say I'm OBD-II that's why I'm biased to the eManage.

All the s13's are easy. there's alot out there for them.

[aleph1]

Well as far as I know, the DE ecus DO NOT have a removeable eprom, which makes it a pain. I know the signle cams do...

[co_s14]

I know it has been awhile but since this is the most informative Greddy turbo kit post I thought I would check in for an update.

How is it running, idle, richness? What is boost at? Etc.?

[rn240sx]

When you get this turbo kit running correctly.... Keep this in mind.When your on WOT racing in 2nd, 3rd and 4th gear, when you get up to about 5k rpm, you will notice that the motor has no power left... It seems like its just turtleing its way to redline...Let me know if u experience that...

You sure about this? JWT has cracked the 96 ECU.

[BomexS13]

has anybody have succesfully installed this kit on a 95(OBD1) model?

[S-14boy]

I just got my GReddy Turbo Kit, and in the middle of installing it, you guys say you can reprogram the E-Manage, do you need software installed on your computer, or do you just plug in Via USB??

[TurboKA37]

you can not access the maps on the emanage they send with the turbo kit because they have locked them. in order to reprogram the emanage i believe you would need to start from scratch and would be pretty difficult
