how much power can a utec ems tune on a built 350z motor? thnk you

 

50.

 

million.

 

dollars!

 

"puts pinky finger near the lip"

 

See in your other thread you're at 6XXhp and wanting more.
Just get a Haltech.

 

it puts the lotion on the skin!!!

 

With the capabilities of the UpRev and Cobb re-flashing in the lower price range, and the Haltech, F-CON and ProEFI in the mid-price range, is there even a reason for anyone to use a U-tech anymore? I've never played with the U-tech, so I don't know all of its functionality.

 

Utec is stupid. Haltech ProEFI and Osiris is good.

 

one billion

 

as much as I want to give a funny answer,

the real answer is 2 fold

1) depends on how much boost you are running.
-The resolution is only 16x16. So if you run 15psi of boost you can tune at evrey 1 psi interval.
-The more boost you run, the larger the areas that have to be tuned in 1 cell.

So, I ran 15psi no problem. Once you get over 20 psi, you'd prolly want to swap EMS's

2) Injector size
-since the UTEC relies on the stock EMS for starting, it doesnt deal well injectors above ~600cc. The stock ECU just cannot scale them back enough, so you get potential hot/cold starts
-you'll often run outta injectors size before you run outta tuning resolution.

UTEC is still a viable tuning option. People that blindly say to go Haltech, Uprev, etc prolly have never used any of those (like Andrei above who is NA !). They all have their problems/limitations as well as advantages.

 

^ +1... I had no problem with the utec... except minor things, but can easily be fixed on on the dyno. if your goal is 500-550 whp.. I see no problem with the utec

 

^^^^

Good info.

 

This is why you shouldn’t make this comment. Trust me, there are features that Utec has that Osiris/Cobb don’t have and vice versa...

1. Third party WB support for self/street Tuner, unless you trust the OEM 02 sensor then go ahead and tune that with Osiris.

2. Active knock control on all rpm and it will only pull timing on the area you are knocking. With Osirs, it automatically switches to a high_Det map which will hurt overall power.

3. Overboost fuel base cutoff. For me this is a great feature especially for Turbo guys.

Those 3 things important to me and most street tuner so that alone justified for me sticking with Utec.

If you want protection the Utec will give you that.. Osiris won’t! If you want perfect drivability then yes Osirs rule over Utec on that side. For me protection > drivability because I'm on stock block.

 

+1 ...

 

I clearly asked a question, you know, with a question mark.

Also, I clearly indicated that I don't know all of the UTECH's functionality, which is why I asked the question.

Anyway, thank you for the clarification on the UTECH's functionality, which does indeed answer my question.

 

/\ that is why I gave a few answers..lol I'm just tired of all the Osiris/Cobb nuthugger that think Osiris is the next best thing since slice bread. Your question didn’t sound like you were looking for an answer but rather instigate how the Utec really has no place in this market.. Just my .02 but I guess I was wrong.

 

I listed the various options that are availble in the question so as to be clear on what my exact question was. The second sentence was to indicate why I was asking the question. But, prior to seeing the responses posted by you, Rich and Vas, I was inclined to think that maybe the UTECH was less relevant than before. The responses have given me better perspective on this. Anyway, there's no reason for me to nuthug the re-flash solutions. Even though I have Osiris for little ****, I still run an F-CON for tuning and various other things. If I were buying today, I would give serious consideration to a ProEFI or Haltech. In other words, I don't care who makes it, just whether it works well.

 

Just a little correction, the resolution is 10x35 or 11 column if you want to add the 0% column but that is for the ECU control. You really just have 10 columns for your load site. At 10psi you get 1 psi per interval and if you want 20 psi then that is 2psi per interval. You are right that the limiting factor is the resolution and IMO if you want to run 16psi+ then Utec won’t give you the resolution to really fine tune your car. Also the injector size limitation. You can always do a reflash to do the injector scaling. Even ttg35fort uses a reflash for little thing with his Fcon so I guess it's not taboo to combine reflash with Utec.. If you combine both then you can try the reflash to control everything below 5psi (because of the limiting factor of the stock MAF) and have Utec control anything above that. Now this will give you more resolution while taking advantage of the reflash capability to control idle and injector scaling... just my .02. The again, just add a little bit more and you can get a Haltech.. lol

 

No blind Haltech call here. OP is already over 600hp and wanting more.
