like it says. i'm most likely going to need a re-tune, but i'm definately not going back to the same shop. or should i just buy the equipment to re-tune myself, or should i get an safc2 and fine tune with that?

i have a socketed ecu with a crappy tune and i want to take care of it before it ruins my motor. turbo wise, i have a .48/.42 t3, walbro, blaster coil, z32 fuel filter, open dump tube, big intercooler, 2.5in. piping, ngk 6re's, that's pretty much it. it's a basic turbo and this supposed awesome nissan shop can't get it done right. after 2.5 months! the reason i mentioned the safc2, is because im trying to trade an unused emanage for it. i was hoping that with that i could do what needed to be done myself. i need GOOD help PLEASE!

What injectors and MAF are you running?

And where is your MAF positioned?

I can probably set you up with something that will work well with your setup. Send me an email, gabe AT hybridka DOT com

email sent, but i forgot to mention maf and bov placement. it's about 6-7in. away from the inlet. also my ssq is on the cold pipe. it stalls if u let off while on boost. i don't know why.

What about your tune is so bad? How much has it cost you so far?

well i ended up not getting the tune because they didn't have the clips i needed for my 550's. so right now i'm running no kind of tuning, with 6-7 psi. i'm going to find the clips and when my spare ecu is tuned, i'll just put it all in myself. as for cost, what do u mean the whole shebang or tuning? i haven't payed for tuning, but either way i've spent to much money because of not doing things myself. i'm going to start changing that. but i don't know jack about tuning so thats what i need help with. i plan to run 10psi daily, and around 13-14psi for *** kickings. if that helps.

So you put in 550cc injectors and corrected with the SAFCII?

Or did you not correct at all? If not, I'm suprized the car starts. Devious can set you up with at least a good fuel correction. From there I'd go with a BTM. Especially, because you want to use a boost controller. Either that or you will need a switched tune. I'd get a BTM.

no safc. no tuning. just turbo hardware, fuel pump, and oil/boost guages. she runs pretty well considering.

Ok now I'm confused. You put 550cc injectors in, so your car gets 2x the fuel it ought to and you are wondering why it runs like crap? I'm suprized the thing even starts. Is DeviousKA helping you with a tune? If not, I can set you up.

no dude, the car is completely stock besides the turbo and mani., down p., dump p., 3in. exh., intercooler, 2.5in. piping, sci/blaster coil, 8.5mm wires, ngk6re's, ssq bov, 38mm turbonetics wg, altima fans, int. butterfly removed, egr removed, stock maf. running solely on waste gate which doesn't pass 7psi, ever. so basically all i need to do is get some kind of tuning for this setup including the 550's. i haven't put them in because i'm sure the car wont even start with those in. plus i need some rx-7 clips for them. now, i have a brand new emanage but i believe tuning the ecu is superior to piggybacking, right? about devious, i sent him an email, but i haven't gotten a response yet.

He is verry busy. Tuning the chip is superior because there is not a huge hacking of the MAF signal. But our ECU tuning is still in the R&D phase. I personally have a hard time trusting our controll of timing at this point. It only takes a small error to blow a motor. Also, tuning this way requires a lot of tweeking on a dyno which can get expensive.

What I'm doing is correcting for my larger injectors and using a BTM for timing.

If you would like, I will sell you an injector/MAF corrected chip for $50. I would use the emanage for timing and fine tuning or I can re-tweek it for you. The second method isn't very practical unless you have a wide band. Also, timing will still be an issue. I can do timing as well, but I'd go with the emanage + pressure sensor and be done with it.

This will be a great setup with no big MAF hacking and it will probably be a lot more practical than long distance tuning. Plus it can handle a boost controll which a fixed tune can't and it can be re-adjusted if you upgrade. Not to mention dyno tuned.

Just re-read your original post. No reputable shop would try to tune that car with stock injectors.

Let me know.

I'm going emanage, and I can't for my life understand why you you would rather run lean on stock injectors rather than use the unit you have, are you afraid to tune it?

Cheeze, I can do a fuel corrected chip for you too. Then use the emanage to fine tune without the huge MAF hack.

I have my 460cc in my still N/A motor now and it runs like a champ with the fuel correction.

i can't use the emanage because i dont have a laptop, wide band, or tuning experience of any kind.

edub1, so ur saying get a chip from u, socket my ecu, put it in with the 550's, then just fine tune with a piggyback?

WHAT A JOKE... edub u don't trust Ecu but u trust BTM ? do u have a clue on how btm works? it still usses Ecu so u waisiting money by getting that crap. 2 40$ for a chip that u don't trust and chip that u made for less than 5$ by using info on eccs.hybridka.com/ cmon guys , chip it urself and take it to a dyno shop that deals with nissans , z32 s skylines etc. they have almost same chip as ka. Contact Pdm racing they tune chips too. And deviousKa is helping you for free anyway/.you either put time AND LOTS OF EFFORT or just pay someone. But forget safc, btm u retarding timing of what table??? factory ecu right... and that is what NA right... there you go

I am not worried... (But also not trying to thread jack). Have ignition and injection harnesses (so MAF hack issues can be easily fixed), will tune using EGT, Wideband, Laptop, and University's Mustang Dyno. I have everything I need.

Don't you already have a socketed ECU? Yes, I can give you a chip that will compensate for the 550 injectors plus MAF should you upgrade that. Your A/F ratio will be close to stock, then you can fine tune with a piggy back and not have the dramatically altered MAF signal that you would otherwise have with a piggyback. This altered MAF signal is what causes problems with piggybacks.

The Emanage will also pull timing according to boost pressure. To do this via ECU tune means the tuner must try to guesstimate where boost will occur and pull timing accordingly. One huge problem with this is that even if one could guess boost areas accuratly, nobody can say with 100% certainty that they know how to accuratly change timing. A few guys suspect they know, JWT does know but charges $600. But nobody else knows for sure. At least I've never heard anyone make a straight forward claim.

Another issue is the amount of dyno time and trial and error involved. To tune an ECU, you will have to learn how to tune, buy a burner and go through a bunch of BS. Plus pay for dyno time. And if you are not spot on with your timing you will blow your motor. It's an expensive way to experiment.

With the chip I will make you, you can hook up the Emanage and take it just about anywhere to have it tuned. No need to dyno test and then send it back for tweeking. They will barely touch the A/F settings and the pressure sensor will pull timing as needed. There will be no grief and no agravation and no blown motors.

Bottom line, people talk a lot of smack. Ask straight forward questions about tuning and see what kind of vague and ambiguous answers you get. This way will work 100% and be hastle free.

So what you are offering is to socket the motherboard and then add a chip which changes the K value. After that the expectation is that timing control will be better since you will not find timing changes based on 'artificial' load changes. Then, they will be more acurate? What do you charge for the service? The thing about the various harnesses available through Greedy is that the unit can then provide it's own grounds, so timing will remain 'virtually' unaffected, since at that point you can change duty cycle and degrees independently (unfortunately, not dwell). How will this not be 'good enough'? I understand that your way is accurate, but proper tuning through emanage can provide an excellent tune at a good price.

EDIT: I apologize, I almost made an *** of myself in that the duties and degress will be set in accordance with base settings, so problems CAN be tuned away, but will require the right equipment. And speaking generally, for the novice, an ECU chip is way easier although never as accurate (if both are done correctly).BTW, I am not bashing you, but I feel that for the money, emanage is a very good solution, when purchased with the correct harnesses.

I would change the K, TP, TTP Min & Max, remove top speed limit & rev limit if desired.

The main thing is that with a piggyback and say 550cc injectors, your MAF signal would be reduced to half it's normal range. So, your ECU is thinking it is under much less load than it really is. The main problem is that timing will advance because of this. If your ECU is getting its timing values from the wrong load range, and you pull say 5 degrees, what value are you pulling it from?

With this chip, your MAF signal is nearly unchanged so your ECU will function as it should and provide the correct amount of timing for your load level - minus what you pull out of course.

The Emanage can be used by itself but it would be much better to use it as a fine tuning device and to pull timing.

You can do this yourself as well. Just buy a burner and chip for about $65 shipped and spend a few dozen hours learning how.

I bought the Moates Flash & Burn for $100 and the chips are $7. I also have a zif socket that was $12 I think.

I figure $50 should cover the cost of the chip and the shipping and leave a few bucks for my time and troubles. I'll throw in the socket 1st come as I have an extra one.

Would you be willing to install the socket? Also, will you do anything for timing?

i found a guy that comes well recomended. he uses the emanage and likes it. so i think i'm just going to have him tune with that. but i'm going to use 450cc dsm injectors instead of the 550's.

I could do that but it will cost about $30 for the soldering.

I can do timing if you can tell me where you want it pulled from. The thing is though, I don't have a real high level of confidence with the available tools. And given that each turbo setup is different it's kind of a guessing game.

There are a few guys out there talking a big game but the bottom line is that aside from JWT, there is no proof that I have seen that anyone has successfully tuned our ECU for turbo. I have asked but so far not one single person has been able to say they have done it.

I know I can correct for fuel because I have 460s in my car and it runs great. I put in the stock chip and it ran for ****. So the fuel part is good.

As for timing - sure, I can follow the present theory and pull a little where boost is expected. But if the software of our understanding of it is off you might blow your motor. Also, the turbo will spool differently in different gears so you will be retarded too far in low gears where boost comes later. Likewise you don't want your Emanage to fool your ECU into thinking you are at half load when you are at WOT.

I'm doing the chip + BTM in my car. Why waste all that time & dyno money trying to get it right. Get the chip, fine tune with Emanage and let the pressure sensor handle timing. This will be a sure thing and will eliminate the guesswork and the headaches.

Timing advance can easily be set to drop in accordance to boost using nothing else but the stock ecu control. It is not necessarily easy as there is a lot of monitoring overhead, but it can be done.

hek1620, I was under the impression you already had an eprom programmer. If you dont, you need one, they only cost about $40.00 and will allow you to update your ecu's tune as much as and as soon as you would like. There are a lot of people including myself that woudl be more than happy to hook you up with tunes to get you started, as well as help out with any questions you may have.

It is much easier and much more productive to go about it this way.

damn, now i don't know what to do. it's going to cost me about $400 to get the injectors and clips in and the emanage installed and tuned professionally. i really like the idea of doing it myself, but how much will it cost in total? getting the ecu socketed, chips, the programmer, ect. i need to run a wide-band in the car to tune properly, right? where do i get my ecu socketed? is it really that easy, especially when ur not too computer savvy?

These are all good questions. And ones that are nearly always ignored. The answer is that the $40 programmer will not work with most modern (USB only) laptops so you'll need the $100 USB one if you plan on having it at the dyno with you. Which you must if you are going to tune.

You can also get a wide band for about $300+ dollars and adjust your A/F ratios your self if you know how, but that still leaves you with timing.

The chip and socket are about $25 shipped and it will cost $30 for professional soldering from a local electronics/TV shop (it isn't an amature job).

Learning to tune when you are not computer savy is going to be tough. I have built about 10 computers and it took me a few dozen hours.

Then there is the practicallity of tuning yourself. Correcting for the injectors/MAF isn't too tough. But, getting the timing right will probably cost you hundreds in dyno time. And, you will risk blowing your motor in the process. Tuning by mail is another practicality issue. Then again you can ball park it and take your chances.

Your choices are:

$160 in stuff + numerous hours learning to tune + hundreds in dyno time.

$90 for a socketed, fuel system correct ECU from me, install your Emanage your self and just fine tune the Emanage.

$600 for a JWT

I have a USB burner and know how to tune. For reasons of cost effectivness and practicality I am only going to tune for fuel and use a BTM for timing. I just can't see how trial and error on a dyno can possibly be more practical.

No disrespect to Devious or any of the hybridka guys who have helped me a great deal, but I think the issue of practicallity and overall cost is often overlooked. DIY tuning our ECUs, timing and all, just isn't going to be cost effective for most people.

BTW, I can send you wiring schematics to hook up that Emanage.

thanks for the info. i'm trying to find a shop around here(sofla) that can tune with the emanage. but it's hard. i thought i found a guy last sat. he came "highly recomended". then he opened his mouth. he said that there's a fifth injector in the intake manifold and that my sohc has a knock sensor. which i am pretty sure neither of those is true. so i'm still looking for someone/shop. but as much as i would love to get the equipment and do the **** myself, it would totally cost more due to me having to rent a dyno for who knows how long. and i just don't trust myself that much.

Oh I feel you. I'm not doing it and I know how to tune and have the burner. Unless you are willing to spend big money, it just isn't practical.

I say get one of my fuel tunes so your ECU isn't totally wacked out, tweek with the Emanage and let it handle your timing via pressure sensor. By the way, the electronic Greddy boost gauge uses the same sensor so you can kill two birds with one stone.

Are you sure that he wasn't suggesting adding a fifth injector or a knock sensor, both of which are possible with emanage as I understand.

BTW Edub, I would probably be interested, what is the next step and can you provide a socket too.
