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

Mines 370z

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!

My money's on EcuTek

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.

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.

Sh0velMan

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.

Mines 370z

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

Sh0velMan

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.
