I have decided to install a fuel return system (for my TNetics ST) along with larger injectors and a boost controller. I need an EMS and am in a bit of a quandary as to whether to buy the UTEC or one of the eManage units (either Blue or EU).

A local tuner has suggested to me that the eManage can be smoother for street driving. I guess that when the UTEC takes over control from the ECU it can be noticeable (hesitation or something) according to him and that while some of that can be programmed out, its still not as smooth as the eManage. He has tuned with both and is generally considered a tuner god around these parts. So I do not want to completely ignore his recommendations.

The UTEC has some advantages, one of which is that its a plug in. But it is also brand new (unreleased for the Z actually as of this post). The eManage requires additional harnesses which brings the price up to where they are pretty much a wash. However, the eManage Ultimate still has the issue with blowing coils (there is no diode fix like there is for the eManage Blue) and I can not live with that. For that reason, the eManage Blue is still in consideration.

If anyone can provide feedback regarding the eManage Blue (or the EU) or the UTEC or has any recommendations I would appreciate the feedback. Thanks.

 

I am not enorsing either one, but I just want to point out that after you buy all the harnesses and the sensor for the UTEC, it comes out to almost $1700. I would hardly call that a wash. You could purchase the EU, all harnesses, the auto sport harness, and have Sharif pre-wire it for you for about $1100 shipped.

I was going to ditch the EU for the UTEC, but just decided for to wait for more full standalone options to hit the market. Right now the only thing availabe is the Motec for $5K and the HKS F-CON for just a little less.

 

Not really. The UTEC Tuner is not essential. The UTEC is $1050 and the Pressure sensor is $129. I dont think additional harnesses are needed.
So the pricing is pretty close.

Also, the EU is not an option for me until they fix the issue with blowing coils. I just can't live with that.

 

That is correct..The Utec will run you about $1100 with everything you need.

 

Again I am not endorsing either one, because I am not qualified to do so, but I have had the Emanage Blue and EU both on my car and have never blown any coils. Who keeps the key in the ON position without the car running anyway? Why would you need to do that? I read a post from Sharif that greddy is working on a fix for this.

 

Can you explain the difference between the regular UTEC and the tuner pro?

 

that price was with the Tuner which is for logging. It is not essential.

As far as who leaves the key in the ignition for 30 secs without running the car, tuners do, shops do, Nissan mechanics do, valets do...even I do somethimes. Its just one more thing to worry about. So until they do have a fix its out.

 

I meant $1365.00.

You can leave the key in the ignition with out the car running you just can't leave it in the on position. The only way this happens is if the car stalls and you don't restart it, other than that I have never put the ignition in the on position unless I am starting the car.

Either way if the EU is out because of this issue, then I guess there is no real point in posting this thread.

BTW, don't let anyone valet your car unless you want it to get flogged!

 

Agreed, I don't even trust nissan mechanics (or any mechanic I don't know personally for that matter) to pull my car into/out of a service bay...I always ask to do it myself, even though dealership visits are few and far between.

BTW, I will have a Emanage Blue main unit (no harnesses) and support tool for sale within the next couple of weeks.

 

Yeah $1365 is with the TUNER which is NOT needed.

Thanks for pointing out that the coil issue is only if the car stalls. I did not know that. I suppose that a little better. Still concerns me though.

Also, the emanage Blue is still an option. Is there really a compelling reason not to go with that? Is it definitiely EU vs. UTEC only?

 

Sorry my eyes are not working well today.

Or if you actually turn the key all the way to the on position and never turn the car on. You have to turn the key all the way until all the engine light turns on. I did this and left the key in the on position without turning the car on for about 2-3 minutes and never burned any coils. Again, why would you do this unless you are going to start the car? I did it cause I just wanted to see how much time I really had. I figured if they didn't burn after 3 minutes then I won't really find myself in a situation where they would get burned unless I did it on purpose.

 

Utec

 

From what we know, I'd say go for the UTEC. That is what I'm waiting on, once more firmware is released.

 

I'm hoping some more full standalones that aren't so expensive become available. Let's see what APS has in store.

 

The end decision wil be which unit YOU feel more comfortable with.Price,tunability,support,reputation of product seem to all be "comparable".Some units have different features which appeal to different people,that is why there is such a big market for aftermarket performance products.

 

In the end I can safely say that TurboXS will cater to the Vq crowd and offer more updates/features in the future than Greddy. It's just a fact since Greddy's product caters to more applications. Perfect example: the utec will soon support the cam timing feature on our cars. It doesn't look their are any other standalones(which I consider the Utec) that will have the support for our vehicles than the Utec.

 

I agree, since the tuner working on the UTEC at Turbo XS personally owns a sick 350Z.I see him paying alot of attention to detail on this project and have rarely seen such eagerness to work with a product as Jermaine has displayed!

 

sweet.... im getting excited.. i cant wait to see what can be done on the 300hp platform.. if they need a test vehicle im down..

this engine managment is going to work wonders for the Z....just wait till more tuners get used to the Z's cray timing and i bet on a stock car the UTEC will find atleast 15-20 more hp. ive seen the results of a UTEC on EVO's and WRX's and i cant wait to get mine

 

I would go with the EU because... alot of people have used it and were very impressed with it. Shows great gains to F/I cars, alot of tunning options. Plus I havn't heard much about the UTEC besides reading the forums. I am going to RUn the EU instead of my blue... Headin down to sharif, once i get the numbers i will post.
