OSIRIS - ROM Loader v1.1
Intecracing is happy to present OSIRIS – Rom Loader software for your 350Z, G35 and Titan.
Get more power and improved driveability with no downtime. Simply load our software onto your laptop, plug into the OBDII diagnostic port, and flash!

Note: Results will vary depending on your vehicle, modifications, octane, and environmental conditions.

Osiris does not support ALL Nissan/Infiniti vehicles. While we have worked on many vehicles with lots of different mods, we have not seen them all. There are various ECU used in today's Nissan/Infiniti which are not all compatible. You will be contacted by us before the transaction is complete to ensure compatability and safety.

Easy installation - Install Osiris software CD to a PC/Laptop and connect the interface cable to the OBDII diagnostic port. No installation or wiring done on the vehicle!
 

Map Switching - Map Switching technology is also included with Osiris and requires no addition hardware (vehicle must have cruise control).Using the vehicle’s cruise control buttons, you can toggle between your preselected maps. We build your tune to include a minimum of 3 different maps to be stored on the ECU(US market). Additional map storage is dependent on model and model years. Daily driver, Drag, Track, Economy, or Valet at your fingertips.

Base Maps for 91 or 93 Octane- We work with you to select the best tuning maps from our library for your vehicle. With the large selection of after-market hardware and wide variety of Nissan models available, there are many variables that affect your tune. We work with you to find the best tune we have for your vehicle. If you change mods in the future, no problem, we'll do it again at no cost

  • Top Speed Limiter

  • Rev Limiter

  • Idle RPM

  • Target AFR

  • Ignition Timing

  • Electronic Throttle Control

How many vehicles can I flash w/ Osiris?

The vehicle interface will link itself to the first ECU it flashes and will then only flash that ECU.
** If you have a need to flash multiple cars, contact us.

How many times can I flash my vehicle?

You can use Osiris to flash your ECU as many times as you would like. The manufacturer of the CPU gaurantees a minimum of 100 reflashes. In practice, we have seen ECUs flashed several hundreds of times without failure.

Will my local Nissan/Infiniti service department know that my ECU has been modified?

It is possible that your local service department will discover your ECU modification. The Osiris flash does not affect any functionality of the Consult II and is transparent to common maintenance and diagnostic procedures. If a service tech were to test for our Map Switching, then they will know.

How do I get my ECU back to 100% Stock?

Osiris Rom Loader is able to return the ECU to stock but you will need to contact us first to help.

I tow heavy loads and would like a map to provide a wider rpm of peak torque gains?

We do not offer a towing map that generates more towing power. We can offer maps with improved AFR, the ETC controls and limiters removed but we leave the Ignition Timing at stock to prevent detonation.

I have already done the 2 deg timing advance. Do I need to set this back to 0deg or will the flash take care of this?

You will need to set the timing back to 0 Deg using Cipher, it is not part of the reflash.

Can Cipher datalog AFR on my 2003-2004 350z or G35?

No. 2003 and early 2004 350Z/G35s do not come equipped w/ factory wide band sensors. To log AFR, you will need to install additional such as an Innovate LC-1+ with RPM pickup.

Will a factory software update erase my reflash?

Yes, the update will overwrite everything, including your Osiris license. If an update is available for your vehicle, please contact us.

I only want to change my idle RPM, Speed Limit and Rev Limits, is there a discount?

There are no discounts for only using certain features.

Can Osiris set a desired AFR? For example, I’m running a little lean, can you guys fix that with a tune?

Yes, the Osiris tune can set a desired AFR to fix both rich and lean conditions.

How many maps can my ECU hold?

There is space for 5 maps on all supported ECU’s except for the 2004 Titan. The 2004 Titan only allows for 3 maps.

How long does it take to reflash my ECU?

Anywhere from 1 to 5 minutes. It depends on how much of the ECU needs to be reprogrammed.

How does map switching work?

Using the Cruise Control Buttons...
-Hold the set/coast toggle down
-Press “Cancel” once for map 1, twice for map 2, etc...
-Then release the set/coast toggle.
-When you release the toggle, the cruise "SET" light on the dash will blink once for map 1, twice for map 2, etc...

Is the Cruise Control still functional with the map switching feature?

Yes

What about those of us who don't have cruise control? Is there any other way to get multiple maps?

We do not offer anything at this time. If you want to build your own Cruise control interface, we can help you with wiring information.

Will the ECU learn around the reflash like other engine management options?

No. When the ECU is reflashed it is given new targets to learn to. Over time as the ECU does learn the tune will get better as your vehicle learns to run closer to the new values.

Where do I get my ECU part number?

1) Connect to your vehicle w/ Cipher (if you know someone who has Cipher), and the text box after you connect will tell you.
2) Call your local dealership's parts department w/ your VIN handy. Give them the VIN and ask for your ECU part number. The number should be similar to 23710-?????
The ECU part number changes w/ software revisions, so even identical ECUs can have different part numbers (and they usually do). That's why there isn't a part number that you can get off the case.
