Mine's Motorsport VX-Rom vs Osiris vs any other ECU reflash
 

I have been trying to search various threads on this topic and I can't really get a straight forward answer on which is the best engine management, regardless on price. I'm looking for performance; you get what you pay for.

I see many comments about Mine's and the immobilizer, which they have worked out with the Z34. In reference to the Osiris, I just have the specs listed on a few websites. IS there anyone other there with the Mine's VX-Rom or Osiris that can speak about the products? Any true data from dyno's would be great.

Again I am trying to gather info on a solid ECU/Reflash with solid performance numbers, again money is not the issue, I am a true believer that you get what you pay for, if the products are equal in price the it's just personal preference at that point.

Thanks in advanced for your input.

Unless you live in Japan, VX-ROM isn't really an option.

So this comes down to UpRev vs ECU Tek, about which there are already a few threads. Feel free to read through them! :tup:

My money's on EcuTek :tiphat:

It's pretty new so there's limited results information available and minimal dyno charts, if that's what you need. I'm currently in the drive cycle of my EcuTek tune on mostly stock Z and still data logging the car for fine tuning. I will post dyno sheets once we get the tune finished and find the time to dyno, but that probably won't be until the end of the summer. There is also a slow adoption with the forced induction crowd - people are understandably hesitant to test out new software on their TT or SC setup.

UpRev is probably the most popular tune for the 370Z. It has been around for a number of years, but it can't do quite everything that EcuTek can (like VVEL adjustments). FWIW, my tuner uses both and claims that EcuTek > UpRev.

Why is that? I've seen several websites that sell the ECU here in the US.

I did see the threads on the ECU Tek but I don't know the brand and know how reliable they are as a company. You didn't explain why? No detail. I'm looking for detail not just not an option, there is always an option and I want to explore every possible one.

Mines states they support JDM ECUs only. Also it is an ECU flash that doesn't use the OBD2 port, so far as I can determine, so you have to send the ECU in. To Japan. Just because a shop puts that they sell a product like that on their site doesn't mean they've ever actually sold one, just so you know. By all means call them and confirm whether or not they can offer the service in a timely manner though. I wouldn't feel comfortable shipping my ECU overseas, however, especially since it's basically a "one time tune" service and is probably expensive (everything else with "Mines" on it is).

As far as the other options, I invited you to read the threads that already exist for them. We aren't here to aggregate information that is readily available for you to read. If someone else wants to take up that task they are welcome to it, but I was simply trying to inform you of the other options and where to find more information. :tup:

See below :tiphat:

:iagree: :tup:

Ok so, you don't have any direct experience or insight on the product either? Just from what you heard or other threads. I'm looking for personal experience or hard data to compare the two. I can't seem to find a solid answer. I'm not going to just follow the leader.

I don't want to use UpRev's switchable maps via the cruise control button.

I did see a post for a EcuTek RaceRom that produced 15-20 hp with the below mods;

HKS Intakes and muffler delete.

The reflash just changed;

1. Raised Rev Limiter
2. Speed Limiter Removed
3. Fuel Map Changes
4. Using EcuTek's RaceRom Ignition Timing Control

The Orisis ECU changes;

•Up to 5 Maps on cruise control equipped vehicles < NOT COOL
•Idle RPM
•Speed Limiter
•Electronic Throttle Control to achieve Wide Open Throttle at all speeds.
•Rev Limiter
•DTC disable
•AFR Targets
•Fuel Compensation
•Ignition Timing Advance
•Cam Phasing for equipped vehicles.

The Mine's VX Rom changes;

Electronic throttle data has been changed
CVTC (Continuous Valve Timing Control) has been changed
Speed Limiter Control has been changed
Rev limiter has been increased from 6600rpm to 7000rpm
Fuel map has been changed
Injection and ignition timing has been reset
Learning and emission control has been retained
Fuel economy and throttle response have been increased

Again I'm looking for numbers and personal experiences with any ECU.

All of the things listed on the 'VX Rom' list minus the VTC control can be done right now in UpRev (Osiris) and tuned to whatever you want. Ie, it's not FROM RPM to RPM. It's whatever RPM you want.

All of those things (including VTC) can currently be done on ECU Tek.

Map switching on UpRev (and likely on ECU Tek once implemented) is done with the cruise control buttons because that's the only built-in input method available to perform the switching. How else would you do it? There aren't any other readily available inputs built into factory switchgear.

You do have to send the ECU to Mine's so that they retain the original immobilizer function. Shipping overseas is not an issue for me. It's $1,009.00 for the reflash at Mine's.

I have read the other post and they don't give me the info that I want. I get speculation. I did come across a few of your questions related to this same topic as well. Again, I'm looking for personal experience.

Why is using the cc controls to switch maps "not cool"? It's not like you lose any cc functionality.

I don't want to switch the maps using my cruise control button...simple, that's my personal preference. That's not the type of product I am looking for. The ECU Tek is running like 1500 plus at the moment and not to many shops know how to tune it. They are a England based company, ok..Mine's has been able to map it without the cruise control map switching. The Mine's VX Rom will work on US 370z's.

I'm sorry, but that is completely absurd.

I would recommend that you contact a local UpRev or ECU Tek tuner and get a custom dyno tune for less than what the reflash alone will cost you from Mines.

You don't lose any immobilizer functions.

You will have better results from a custom dyno tune than you will from Mines' canned tune, without exception.

It's my personal preference, I don't want to do that. Period.

Is your Z reflashed, if so which one did you use?

This isn't accurate. Dynotronics will sell you a license, cable and e-tuned ROM (you take logs and send them in for adjustments) for $950.

If there is a tuner local, you can likely get a dyno tune for around the same, give or take.

You can definitely get an UpRev tune for less than $1k.

I run UpRev with a tuner cable so that I can change my own ROM at will.

I may switch to ECU Tek in the future if there are dyno proven results that they are better at getting power than Uprev, but that remains to be seen.

If I were just starting out and had no interest in being able to tune my own car, I would probably go with ECU Tek simply for the extra features they already offer.

Actually it isn't. Depending on the vendor, you're looking at around $500-1000. Most tuners can also email you updated tune files if necessary. Will Mine's do it without another check? Even if they did, the downtime would be an issue for me. And how would you get a dyno tune for your specific conditions if you have to send the ECU to Japan?

EcuTek Tuning GB with cable, and free shipping= 750.00$

This includes all your calibrations(tuning), with lifetime updates, your license, and the interface cable.

If you prefer not to change maps via cruise stalk, there will be options for that, so that's an easy issue

I check local shops they use the Osiris product. I'm waiting on them to respond about the ECU Tek and Up Rev products.

Don't get me wrong I appreciate the insight, I was just looking to see if anyone had any of the 3 ECU's that could speak on their personal experiences.

Then don't use it, my car uses Uprev and we never enabled the cruise control option. I have a single tune.
Also, you seem to be stuck on this Mine's is the "best" idea. Which is fair for some cars they work on, but the z34 does not seem to be one. Especially this ECU reflash. It sounds more like a canned tune, adjusting preset options to increase performance.

This will never match the ability of Uprev or ECUtech on a dyno or street. Now if you were in Japan I would say go to TS, Mine's, etc for a tune because they can see your car and tune onsite see different parameters. Or better yet, just fly Smokey over and have him do it: http://www.the370z.com/texas/14745-s...s-houston.html

Um, my 370's rev limiter is set at 7500 by Nissan. Something's not right here.

It honestly sounds like Mine's is selling a generic canned tune upgrade, that change is for a VQ3.5de motor.

Ok this sounds cool...So I would send the list of current mods to the dealer and they will send me a map to upload the new data and as I add more mods they will send me new maps? Is this correct?

Basically. You'll have to do some data logging and send them results, and then they tweak the map based on how your car is responding.

Ok so you direct experience with Uprev, question, in reference to the changes from stock to using the Uprev what did you notice? Are you seeing better response, better gas mileage, in your opinion what is the most significant change?

UpRev = Osiris. Just so we're clear.

So I get the car on a dyno send them the results based on the mods I have they then analyze the data and send me a new map?

Don't get me wrong totally understand the benefit of getting the car tuned along with the ECU at a shop, I just want to hear people's personal experiences with the products they have. Everyone drives differently what might be good for you and I may not be good for others. I'm just trying to get peoples input on there experiences. I do appreciate the info thought.

Ok, gotcha, I was unaware of that..thanks

On the dyno or on the street. I'd assume there's a good bit of street data logging, since not all of it is just tuning WOT. Other tuners offer the same type of service with Uprev, so you definitely have options there. I'm currently running Uprev, but very little of my experience will be applicable to you unless you're boosted.

FYI::
Mine's VX-ROM

Only person I saw with Mine's ECU was in Thailand, the opinions and thoughts are a little generic: http://www.the370z.com/members-370z-...mines-ecu.html

It looks like you are already, but I'd knock Mine's off of your list. It's a bit extreme to have in the US...anything goes wrong, you're SOL out here with no support.

The thing is, until someone does a back to back comparison with the same tuner on the same dyno, it's going to be difficult to say for 100% sure if any tuning solution is truly superior to any other solution FOR THE END USER.

There will always be differences for the tuner themselves, which one is easier to use for them, easier to license, easier to make incremental changes and track those changes, etc. But for the guy driving the car, it will take proven dyno results one way or the other for there to be a truly "better" product.

So try and wrap your head around that and look at it not as "which tuning software is 'better'" because it's just a means to an end. Asking people that have Uprev on their cars what their experience has been like is going to get you a lot of "It's been great!" and "My car drives lots better and makes more power".

Ask people with ECU Tek the same thing, they're going to give you the same answers.

What about my post led you to believe that I don't have any direct experience with EcuTek? If you can't read what is posted, then no one is going to be able to help you. I currently have an EcuTek tune. I'm very pleased with it, but then I have no experience with any other tuning software to compare it with.

Personally, I think you should waste your money on a canned tune that matches your user name :tiphat:

Ok cool thanks!

Thanks I read the thread.

You guys get offended quick here I see. I posted the question to get an answer. No need to take it personal my friend, it's just a car forum.

Get the mines Ecu reflash and tell us how it is.

I just might do that and let you know.

lol I didn't take it personally... it's the internet :ugh2: I simply responded to your post in which you stated I didn't have personal experience with EcuTek. If you had read any of the many EcuTek threads, you will find plenty of people asking for exactly the same thing you are: results and dyno graphs. Like I said, they're slowly trickling in because the software is so new. UpRev has a lot more history, so if you're basing your decision off other people's experiences and dyno charts, that's going to be the software with the most information.

Like it was mentioned before you don't lose any functions for the cruise control. It is an option I guess you could say I want a map that is fuel efficient and one for the track. I like the dual mapping as I have one for just n/a and one for when I am running nitrous. It has been so long since I have been home but I am pretty sure you have to hold a button down at the same time with cruise control and you will see 1 flash or 2 flashes that designate which map you are running. So with that said no accidental map switching while driving. Lots of threads on here with actual users on both Uprev and Ecu Tek platforms, I am sure you can find some good information using the search engine.

Thanks for the info. Per a previous response I would opt out of switching the maps for the cruise control and run just one map all the time. When you did run the NA what was one of the most significant changes you noticed on your car?
