It looks like the 350z is finally getting ecutek tuning options rolled out. Z1 announced it and it sounds like any of the Ecutek tuners will be able to offer this. It looks like the 04+ DEs are supported and the HRs. They are still working to add the 03 ecu and Revup ECUs. This is pretty big news and it will be interesting if they will be able to get all of the features that Ecutek adds to the vq37 available on the 350z.

 

Im not familiar with the EcuTek platform, is it similar to UpRev? When you buy the tuning package do you only get the interface to reflash the ecu or does it come with a license as the uprev cable?

 

Once they roll out support for the 03, I'll be looking into it. I'd love to have flex fuel options without having to jump to a standalone.

 

Yea, GreyZ, can you educate us on EcuTek vs UpRev? my ECU is tuned with Uprev but what are the benefits with EcuTek when compared with Uprev?

 

From the looks of it, its gonna stay from Z1 only? The price they charge is quite high honestly, $1100+ for just the software/dongle? At that price point, its pretty close to a Link.

Wireless dongle is nice, flex fuel, phone tuning/sending logs, and being able to access features with your phone.

 

There are several others that are offering this new ecutek tuning option.

 

Most tuners that have ECUtek tuning privledges will have access to it - not just z1. Moncef already has it posted on his site. Tuners have to buy another tuner’s license from ECUtek though … so it may not roll out as fast as people think.

ECUtek is just Uprev, but updated and better…

the thing is, and will be, your tuning can only be as good as your hardware … so the DE/RevUp ECUs dont have much extra inputs and outputs and I dont know what ECUtek is going to do for re-allocating spoken-for inputs/outputs.

Possibly ECUtek will allow the tuner to re-purpose the evap solenoid or the AC pressure sensor or possibly the O2 sensor inputs.

But there is no MAP sensor capabilities on the DE/RevUp like there is on the HR and VHRs …

It’ll be interesting to see how it plays out.

Plan on shelling out some cash, ECUtek has some investments to recap

 

I could have sworn Soho said it wouldn't work on older cars or at least wouldn't have the same features as the newer cars. You shouldn't be programming on a wireless connection, that's begging for problems.

 

In response Uprev lowered their pricing, and is including all the ARC features for free with the reflash license (how it should have been originally).

 

Gotcha, the branding on the video made it seem like an exclusive.

Hopefully this pushes them to make Uprev better again.. RIP Cipher.

 

I received mine yesterday for my 2004 350z. There was a question initially if my O2 sensors were wideband, something about 2004 being a transitional year.

It worked out, I installed it, received a level 1 tune. Loaded easily. They requested some test runs to record the logs. I sent those in and received a revised tune. Loaded and repeated the tests. Once I have rev 2 I'll report back.

My 350z is mostly stock with a takeda stage 2 CAI and Gemini catback exhaust, stock catalytic converters.

 

For a naturally aspirated VQ, there is no benefit to using ecutek vs Uprev. You will make the same hp as long as your tuner knows what they're doing. Different software doing the same thing doesn't make more power

 

$675 USD Z1 motorsports. They've been very helpful.

 

I'm sure you are right. I just like the ecutek interface and using the phone. Plus I'm not really very automotive knowledgeable so I'm happy they are doing the tuning using real time data.

 

ok this is what I was assuming, not too knowledgeable in tuning but the analogy is using microsoft word to write an essay vs notepad.
I'm N/A so its all good. Although I don't have any of the ARC features I hope that goes down and maybe I can get launch control.

 

All 6MTs get launch control with Uprev

 

I am most certain I don't have it. I got it tuned ~8 years ago and I am unsure if it was offered at that time with Uprev. I know its offered now but I would have to get it flashed on. I do have valet map though.
Is it something I can mail in and get it flashed on for free?

 

That was right about the time they released it. The features are available for no extra charge now, but you would have to get retuned to add them

 

It is similar in that it is a oem ecu reflash. You get a dongle and then the tuner will have the license/credits that are consumed when they do the tune.

I am not an expert in this but from my understanding ecutek is an easier platform interface for the tuners to use. A skilled tuner should be able to make the same power with ecutek or uprev, but apparently there are better failsafes, interfaces and a few additional capabilities that ecutek adds over uprev.
Phone flashing/map switching
Flex fuel
ecu boost control
Hybrid MAF/MAP tuning (not sure if this will be available for the early cars.
Additional ecu inputs and failsafes that can be tuned in.

Strongly agree with this. You won't make more power with a competent tuner, same goes for standalones also.

 

Hey, I’m new to this thread I plan on buying this for my Z next week I was curious on if I’m going to be able to install this with a stock intake right now and then later on add a plenum spacer and 3in intake a would I be able to retune it no problems or should I wait until everything’s installed?
