DataViewer just won't find the U7191. Restarted machine. Still won't. Unplugged serial cable and power supply. Still won't. Deleted port, restarted PC, still nothing. Ideas?
2006 Impala if that matters, and no other problems to date.

RE: Searching for a connected tool...Scanning ports...
Well if you unplugged it and deleted the port, of course it won't find it!! 
sorry, just had to LOL
are you sure your serial port is enabled?? have you checked it through the computers BIOS settings to make sure ?? Has it worked before and it just stopped??
and in Windows, if you go to the port's properties/settings, going down the boxes mine are : 115200, 8, None, 1, None

I deleted the port and let the PC re-recognize it. When it did so, i turned off the PC and plugged in the serial cable...then i plugged in the tuner. Still didn't work. After a couple times of unplugging the tuner and plugging it back in, it finally worked again. It worked every time before this. All of the port settings are the same as yours, Lew.
Also, when it starts up, it tells me that the vehicle is not recognized or something like that...is that common for the 7191? It has also says that there is no vin for the vehicle...again, is this common? Is there somewhere where i should be telling it what the vehicle's vin # is and what type? I haven't messed around too much with the viewer, only enough to download the data into Excel files.
This is what i get when it's connecting with the tuner:
"Connected Vehicle:
VIN Unavailable
Unknown Vehicle
GM E40/CAN"

wierd that sometimes it works for ya, and sometimes it doesn't... interesting.
as for those info/error messages, yeah that's normal... I get it too - cuz we're not connected directly to the car via a laptop w/the dataviewer - that's why we get those messages.
If you had a laptop, and connected the Predator to the OBDII port, then used the serial cable to connect the Predator to the laptop, you could monitor the data real-time in the dataviewer, and it would also find/see that info from the car.

Hey, completely unrelated topic, but question for you on aftermarket add-ons. I'm thinking of dropping some cash on a K&N CAI and a couple Flowmaster Super 40's. I should have my U7191 by the weekend. Will performing either/both of these mods (either before or after applying a Diablo tune) change anything related to the tune? In other words, can the U7191 compensate for these easily, or will making these mods in turn require me to tweak the tune?
Any advice or guidance on this would be greatly appreciated.
Thanks,
Kevin
Hey Kev...
We will need to tweak the tune regardless, because the tune itself tends to lean out the car a little.
installing a CAI will change your air/fuel ratio, cuz now you'll be sucking in more air. When I installed my CAI (http://coldairinductions.com/W-BodyLS4V8ColdAirBox.html) it made me more lean due to more air being brought in.
the Predator can compensate for this, that's why we log to see the fuel trims and adjust the injector slope to correct the fueling
.
As for the flows, I'm not sure - I haven't bought my super 40's or gotten them put on yet - waitin' for cash!!

I'll be sure keep you posted and get some logs going. I haven't put a CAI or the 40's on yet so it's pure stock. I planned to get the 40's this weekend, though I may just wait until I get this tune installed and dialed in before I go and make any mods like CAI or exhaust.
Thanks again Lew!! I'll keep you posted, and thanks for all your help!
