I have no doubt that Buschur can do a good job with the UTEC, but you should drop off a copy of the manual a few days early and expect that you'll be paying him to figure out the system on your car as he has absolutely no experience with the zUTEC. It's important to remember that the zUTEC is a whole different beast then all previous versions.

With the limited availability of the platform, and with very few dealers currently trained on the system, you may find that a road trip to a trained dealer is well worth your time. My only recommendation is that you bring your own gas with you as blends can change drastically across the country.

It’s a long drive, but MD is currently the center of the zUTEC tuning universe. I’d hate to have an early adopter have a bad experience because someone unfamiliar with the system has a hard time getting the most out of it.

TurboXS currently states that the front 02's are not input into the UTEC and it does not have the ability to log it properly. This makes sense becasue TurboXS uses Bosch WB02 Sensors. The Nissan uses NTK sensors. The voltage offsets and resistance calibrations are very different between the two. Also the UTEC may have been designed to only recognize narrowband sensors from the factory which use a 0-1v signal as opposed to the WB02 0-5V signal.

The Innovate can be confirgured to be input into the UTEC we would just need to log the voltage output of the Tuner vs the AFR. Then with the Innovate Logworks tool we will be able to change the voltage offsets so that it meets what the UTEC is expecting. The only outstanding issue is aquiring the connectors and confirming the wire diagram.

Oh, and get this my car was broken into today in the work parking lot. Someone broke my passenger side window and stole my radar detector and all my change. What a world we live in today. If I would have known, I would have taken the radar detector out, taped a $20 bill to it, wraped it with a bow and put it on my roof just to not have the POS break my window.

Can someone please clarify this?

Also, assume I get the UTEC, install it, and have it tuned. Is it "always on", or do I have to manually select a map to run, or what?

Thanks Mike and Jason and all the guys at AAM for the outstanding customer service.

In other words it is a so-called "dumb" computer.

Lets say the EU was tuned while the car is using Map B, which is normal for dyno conditions. Then the car is taken out and run on the street. Things are nice and peachy until the car decides to run Timing MAP A becasue the weather is cool, no knock is detected by the factory knock sensor, and what ever other conditions are met to move to the A Map. Now on the A Map your timing is Advance by 2 to 7 degrees! This is completely unsafe for any high performance/compression/boosted motor.

The factory ECU also has a dynamic fueling stratagy that can vary fuel trims by ~20%. A 5% swing is huge for any performance motor.

The UTEC is a so-called "smart" computer. It is able to determine when it wants to fire the coils and injectors. Its has its own drivers, just like the factory ECU to tell the injector to fire and to tell the coil when to ignite. There is no way for the factory ECU to trim fuel curves and no way for the factory ECU to advance timing. The UTEC has just taken that control away. For a naturally aspirated VQ this is not a huge concern, but for a boosted motor this is the safest way to go about it. Without a doubt this is THE PREMIER Engine Management, short of the HKS F-Con Pro.

I understand those are designed to protect the motor from poor fuel or excessive heat which could lead to detonation, but how does the UTEC do this? Does it use the factory knock-sensor and adjust for a range of conditions or are you locked into whichever map you've programmed/selected manually?

Thinking of this product for my Z in the UK (Vortech SC, Kinetix SSV & hi-flow cats, Nismo exhaust).

My current setup uses an AEM UEGO2 wideband O2 sensor. Will I have to dump this? Or can it be re-used?
