Frequently Asked Questions

Do we want this to be a single page with a list and answers, a set of categories each with a list and answers, or do we want each question on a single page?

I think it would ultimately come down to how many questions we plan to have.

Here's an example of everything in a list with anchors to the given questions using what's currently on the site.

Is the Cipher w/ Osiris different than the stand alone version?
The version of Cipher bundled with Osiris is the exact same as the stand-alone version. This includes the ability to use Cipher on multiple Vehicles.
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 at info@UpRev.com.
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.
What parameters should be logged for AFR eTuning?
  • AFR Bank 1 and Bank 2 (See Cipher user guide)
  • Accelerator position (either one)
  • Base fuel schedule
  • Calculated load
  • Coolant temp
  • Engine speed (RPM)
  • Ignition timing advance
  • Throttle position (either one)
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.
Is there an upgrade route for current Cipher owners?
Yes, but your current Cipher cable will not function with Osiris. Contact us at info@uprev.com and we will walk you through the details.
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 UpRev reflash?
Yes, the update will overwrite everything, including your UpRev 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.
What versions of windows have been tested?
Windows 2000, XP, and Vista.
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-?????
3) 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.
Can Osiris be used to rescale fuel injectors and MAF sensors?
Osiris Loader does not support non-stock injectors or MAF sensors. If you need this capability please contact us.
Can I modify my own maps and do my own tuning?
Osiris Rom Loader uses maps prepared by UpRev. We plan to release a full tuning version of Osiris in the near future that will support both NA and FI vehicles. No release date has yet been set, but an upgrade path will be made for Osiris Rom Loader users.
I bought a Cipher system from another user, can I use it on my car?
Yes, Cipher is an non-licensed product and requires the cable to be used. As long as you have the cable, you can use Cipher on a supported vehicle.
I bought an Osiris system from another user, can I use it on my car?
Yes, the cable needs to be relicensed and you will receive one free base tune, and one free eTune update. All eTunes after that will need to be purchased separately. There is a $50 relicensing fee. Osiris only works on supported vehicles.
