Product Description

Z1 engine tunes do not disable emissions control systems or the onboard diagnostic (OBD) system. The customer is responsible for ensuring the hardware they are using on their vehicle does not cause a failure to meet emissions standards.

Now you can reflash your ECU with a custom E-Tune. This reflash is dependent on you owning an Uprev cable and the ability to data log your vehicle. This listing is for one (1) E-Tune program based on your Data Log. Each E-mailed Tune will be $150.

Parameters that we will tune include:

Up to 5 Maps on cruise control-equipped vehicles
- Map switching may not be possible on all 2013+ models. Z1 is aware of an issue and is awaiting a resolution from UpRev.
Idle RPM
Speed Limiter
Electronic Throttle Control to achieve Wide Open Throttle at all speeds.
Rev Limiter
AFR Targets
Fuel Compensation
Ignition Timing Advance
Cam Phasing for equipped vehicles.
Optional: NATS (Nissan Anti-Theft System) disable is also available using the options below.

**THIS PRODUCT IS ONLY FOR GAS POWERTRAIN EQUIPPED VEHICLES**

In-house tuning is also available, please contact our service department for details or to set up an appointment. [email protected] or 770-838-7777 ex 311

eTune Steps

Purchase the eTune.
Data Log your vehicle while running the Tuned Map that is to be changed. (Usually your 91 or 93 Performance Map)
Email the .csv Cipher Log to the [email protected] mailbox.
Wait 1-2 weeks for us to review the logs and make the necessary changes to your tune.
When your response email arrives, your new tune file will be attached. Save this file to your Uprev/Osiris directory or another location you can easily find.
Flash the new tuned ROM file onto your ECU.

The following parameters will need to be logged prior to e-tune support:

AFR Bank 1 and Bank 2
AFR correction Bank 1 and Bank 2

Please understand that not all Nissan Trucks ECU's have ROM's currently available. In the case that your ROM is not available, it has to be sent to UpRev and may take an additional 6-8 weeks to complete.
