Got my UpRev cable in the mail today. The software worked fine on my little netbook (Dell Inspiron Mini 1018, nice for a tiny car/travel laptop), running Windows 7 Starter (just for UpRev, I dual-boot over to Ubuntu for anything else).
Cipher: The UI on Cipher is a bit clunky, but it does do some neat stuff (like talk to the BCM and test wipers and windows, etc). Clearly they've got a lot more inside scoop on Nissan's CAN and custom PIDs, etc than generic OBDII software does. The data logging supports a lot of Nissan-specific parameters too, but I haven't had time to play with it a ton. Several interesting buttons were greyed out, related to adjustments that could possibly be made by Cipher, and maintenance operations for ABS and the fuel system. Maybe not supported on this car, or maybe those only come with an upgraded license?
Osiris: Flash process went pretty uneventfully. One oddity I noticed during the flash process (aside from all sorts of unusual dash light combos) was that the engine fans spun up and kept blowing the whole time. I was sitting there thinking "gee I hope this flash goes relatively quickly before those things drain my battery, which started as 12.08V". Most likely this is just something the ECU does on its own, not Osiris-specific. Luckily the flash is pretty quick compared to some older cars I've done this on.
I don't even have an "e-Tune" at this point obviously, since I haven't sent them any data logs from my car. They created some default "tuned" map for my Map 1 based on a mods list, I'm sure it must be fairly conservative without data to go off of. I also had them up the idle speed to 700rpm, up the rev limiter to 7750, and remove the speed limit for that map. Initial short drive on it went fine. Car seemed a little perkier, but (a) it probably hasn't even finished re-learning fuel trims from the ECU reset yet and (b) it's probably all in my head
The map switching functionality is just awesome, it'd almost be worth it without any performance tuning capabilities. I had them set up my Map 2 as a Valet mode limited to 3000rpm and 30mph, and Map 3 as a Security mode limited to 2000rpm and 5mph.
I tested out the Valet Mode and tried to defeat it. WOT seems to sometimes bypass the low rev limiter for a very brief moment, but the speed limiter can never be evaded, all in all it works great. If I were a Valet trying to hotrod this car around before parking it, as soon as I realized the car was refusing to go over those limits I'd give up quickly, maybe even be worried that I might have broken something and might get blamed for it (given that the rev limit responds in a bouncy fashion, much like our true higher rev limit).
The security mode lets the car run, but it can only crawl at 5mph. Aside from setting that before shutting down the car, I might switch to it when I want to run into a store quickly and leave the car running. Then I don't have to turn it off, but if someone managed to jump in the car, I can catch them on foot
I'll probably go for a dyno run sometime in the next week or so, probably down at EngineLogics since they have that well-maintained DynoDynamics unit there, which is what my last graph came from ages ago. Mostly just to get a new baseline, and make sure I'm not running too lean. Then I'll see about having them (or someone?) dyno-tune the AFR targets and timing advance once I get the FI Long-tube headers installed.
