More Info:

The Z UTEC is a Plug and Play Parallel Engine Management System. Designed to work together with your factory ECU.

The front UTEC Ports from left to right. The RJ-12

Adapter allows for Serial Port connectivity with the use of our

adapter. The large connector in the middle is where you will connect

the factory ECU. This is part of our plug and play installation, zero

hardwiring is needed. Located on the far right is the UTEC On-board map

selector. This used to switch between the 5 map locations, valet and

security mode.

The rear UTEC Ports from left to right. The first

port is the UTEC 9v power input. This is used to power the UTEC outside

of the vehicle. The second input is the optional Map Sensor input. This

is used when running a vehicle in Speed Density Mode. The optional map

sensor has the ability to read up to 70 psi. The third input is to use

a USB adapter to connect. The fourth is yet another form of connection

to the UTEC, DB9 Serial port. The last port is to connect our Remote

Map Selector. This allows you to remotely switch between the maps.

The UTEC gives you the ability to let the factory ECU

drive the car under normal cruise conditions then take over when you

are ready for the power in a flawless manor. This gives you like stock

drive-ability with the advantages of a powerful stand-alone system. The

UTEC allows you to maintain OBDII compliancy while remaining unnoticed

to the OBD Scan process most states are adopting these days.

In basic form we allow control over Fuel and

Ignition Timing. Each control gives you 250 rpm resolution from 500 rpm

to rev-limit with over 10 different load sites.



The

UTEC will ship with pre-programmed base maps to help get you up and

driving right away. In addition to having a pre-programmed base maps

the UTEC has provisions for 5 different map locations. The multi-map

capability allows you to use our remote map selector to switch between

the 5 maps or stock mode on the fly. Your tuning options are endless

when you can have a race map and daily driving map at the tip of your

fingers. The power is all yours!

The easiest way to visualize it would be to break down it’s components into separate systems.

Fuel Control- The UTEC has two fuel

control modes. Each of them have a fuel map that allows the fuel to be

adjusted at each of the 250 rpm resolution with over 10 different load

sites from zero to rev-limit.

MAF Pull Up/Down- allows you to intercept the

MAF signal and add or subtract up to +/- 50% of the signal. This form

of fuel control works best for mild naturally aspirated modifications.

Speed Density Fuelling – allows you to use

your MAF for low load cruising situations. Under heavier load the UTEC

will employ Speed Density Fuelling. The fuel map will allow you to

enter Injector Pulse-width X10 into the table. This allows for precise

fuel control. In the map you are now specifying millisecond on times of

your injectors. This mode is a necessity for Forced Induction vehicles.

The UTEC Map sensor is required.

Ignition Timing- The UTEC gives you

complete control of timing. This is not done on the basis of offsets or

altering the crank signal as some engine management systems use. The

load reference we use is RPM vs. MAF or MAP which is optional. This

allows the fuel map to be adjusted at each of the 250 rpm resolution

with over 10 different load sites from zero to rev limit. When you

enter a value into the Ignition Map you are actually typing in Degrees

Before Top Dead Center. The UTEC fires the coils based on these values.

No more wondering if the stock ecu is going to advance or retard timing.

Knock Control- This feature allows you

to help keep your motor in one piece. The UTEC contains default knock

thresholds but can be adjusted at 1000 rpm increments up to 9000 rpm.

It also contains a Knock Count threshold that allows you to define how

many counts of knock before the UTEC will respond with a Knock Retard

Step. The Knock Retard Step is the amount of ignition timing that will

be pulled per knock count to a defined Knock Maximum Retard. Knock

Maximum Retard relates to the maximum degrees of timing the UTEC will

retard per knock event. When a knock count is registered the UTEC will

hold the retard for a set number of crank cycles this is called Knock

Retard Duration. The UTEC also has the ability to apply a global Knock

Correction to the entire map once a knock event is evident. This will

help ensure that you keep your high compression monster together. All

of these features are the UTEC’s safety net. They should be used

pro-active not as a reactive measure.

Datalogging- The UTEC Datalogging

function helps you to keep an eye on your engines vitals. Using the

logger gives you all the information you want to know about your

vehicle. You can take multiple logs of your vehicle whether it’s simple

driveability or all out racing. You can be sure the UTEC is keeping an

eye out when you can’t. The main logger (Number1) contains rpm, map,

maf voltage, tps, load site, afr, ignition timing, injector duty cycle,

modified fuel (fuel control) and more. Logs can be output into text

files or csv files for easy comparison. When the UTEC is used with a

TXS Tuner model it can also supply you with w/b afr readings in your

logs as well. Giving you the ultimate tuning package.

Injector Scaling- Allows you to scale larger than stock injectors making coarse adjustment to your fuel map.

Remote Map Selector- The remote

selector gives you the capability to switch between your UTEC maps. It

also allows you to revert back to full stock ecu control on map 0 (when

stock sized injectors are used). Maps 1 through 5 are your UTEC tunable

map locations. Map 7 is your security mode, the car will not start. The

car cannot be bump started or jumped when security mode is enabled.

Rev-Limit Control- This feature allows you to adjust your primary rev-limit on your 2003-2004 350Z.

Programmable Shift Light- The shift light function lets you set the 3 RPM points at which to turn on a the optional three color shift light.

Spare Solenoid Drivers- Allow you to activate devices in a 3D map like Water Injection, Nitrous, Water Sprayer etc.

Software Upgrade- The UTEC will have

periodic software updates to further innovate it’s tunability and

flexibility. The most current version of software will be available on

our website http://www.turboxs.com/.

The Z UTEC will be ideal for both Forced Induction and Naturally Aspirated Mods
