I really want to try this after seeing shawn's demo on his car. Does this have knock control also like the utec?

IMO for 600 with a tune by Shawn this has to be one of the best bang for the buck mods we can do...especially once we have bolt-ons
With RevUps I heard alot of guys getting their tunes "washed" out by the ECU learning around it and some guys changing to speed density tuning. Then there are the issues of it coming in and out of stock map to UTEC map and hiccups....
OSIRIS is just so clean and simple that if your not shooting for more than 450whp or so its a no brainer....it can scale injectors easily too so ST or even TT guys can have a quick tune ....its just so user friendly as you saw Shawns demo.....got me even more excited to see the efficiency in which the software could manipulate the values in real time and creat a smooth pull with no hiccups....at 75 an hour time is of the essence and I think you have to do some serious tinkering for Shawn no to tune a car in more than even 2 hours ....that 150 is cheap when you consider that some standalone tuners charge than ea hour they tune a motec or some other not so user friendly system (as compared to OSIRIS)
If your shooting for 800whp than an FCON may be your only choice at the moment but for the majority of the Z community the OSIRIS packs enough punch for serious NA work and a small shot while also being extremely affordable and reliable...600....most people spend more on an exhaust than that! lol

I don't want more than 450whp anyway that is enough for me. The numbers in my sig are on his dyno with the SS box.
I want smoother pulls if possible. I'm just worried about it working with my fuel pump and JWT FMU.

This may seem like a weird question, but I am looking at some screenshots of Cipher, and was wondering if there are any buttons below the "Coolant Test" button (within the scrolling section, above the Quit button)? It looks like the scroll bar goes a bit lower, but it could just be that particular screen capture or something.

These ECUs are VERY powerful from the factory.

Since Osiris flashes the ECU with "targets" for the ECU to tune towards, how can the ECU tune differently when the weather changes? Doesn't the ECU always tune towards its targets?
You know I'm not arguing with you, Jared. I'm just trying to figure out how the ECU really works. I'm thinking about a few quarter mile passes this Winter and I'd like to have the best tune possible.

If you have a lot of heat (summer) the AFR will be adjusted by changing the pulse width of th injectors (ECU will adapt) and the ignition will retard slightly to prevent pinging. The cam's can also change their timing in some ECU's, I'm not sure the capability on the ones in our cars, but I'd imagine its programmed for. You might be able to get more power tuning for hot/cold, but its probably less than you think, adaptation levels are usually in the range of 20-25% for stock cars (any Fuel injected car in general) and that leaves a LOT of room for conditional variation.

Foe those that have bought Osiris what would recommend for the Idle at. Here are my mods to date.
Single Exhaust = Nismo
Air Intake = K&N Seris 63
Intake = MotorDyne 5/16 ISO Spacer & Mrev 2
Pully = Unorthodox Pully "Stock Size"
I plan to add HFC's an Headers.
Thanks,
Chad

My thoughts were a slightly higher idle may help make starting in daily stop and go traffic a bit smoother/easier. Also, a higher idle will hopefully reduce my tranny rattle when stopped with the clutch out (it does seem to lessen if I increase the RPMs a bit).
Also curious to hear others' comments on this.

I didn't have Osiris change my idle. My G idles at 600rpm normally and at 800rpm with the air conditioning on.
Remember that you can adjust the idle plus or minus 250 rpms with Cipher. Cipher comes as part of the Osiris package.
