How do I find the minimum/maximum voltages and readings?

If you bought the wideband new, the manual should list it.

thanks i got it set up
Browsed through that PDF. I think I've read it before as well. It explicitly uses a scan tool in the instructions for closed loop tuning. I didn't see anywhere where it said that it was optional. If you have a good tune, it's because you started with a map from someone who used a scan tool or a lot of trial and error.
The ESC section is the most interesting as it kind of explains what the SSAFC is doing to the O2 signal. It sounds like after the over pressure setting it will output a .5v steady signal. This will keep the PCM from using any STFT, and you can tune like your are in open loop mode.
The problem with this is you will still have a transition region because under stock maps, you need to add fuel in closed loop and pull fuel in open loop.
This sentence tells me a lot.
"Some people have reported that the ESC function will kick out and go lean if you stay in the activation range of the ESC too long like going up a mountain."
If anyone has also read my AEM FIC posts, I have reported that the car goes into open loop mode if you stand on the throttle for more than three seconds regardless of RPM. Sounds like whoever reported to U-tune had cars that were running too lean in open loop mode, so they had positive trims in closed loop. When the car switched to open loop below the normal transition point, the trims disappeared and the car ran super lean. This can be fixed by tuning out the trims.
Unfortunately, in our case, our open loop map is very rich from the factory, but we have to add fuel to bring down the closed loop 14.7 normal operation under boost. So when we switch to open loop before the normal transition point we get the extra fuel + the stock rich fuel map, and we get a whole bunch of unburnt fuel out the back of the exhaust.

who cares how it works, just tune it and be happy. its cheap as hell so i dont expect it to have a shitload of features or be the best out there

so i asked this before, but didnt get an answer. and im getting dyno tuned soon so just wanted to know. at what point do the stock injectors not supply enough fuel? i plan on getting tuned at 12psi on the stock turbo. in case it matters, mods are Corksport 60mm catless exhaust, thunder manifold, cxracing front mount, coolingmist methonal injection set at 6psi, one step colder plugs...

ya your getting pretty close at 12psi
oh and also tonight it was strange, or today also, but anyways, it was 65 out today and the car was stumbling on it's ass from too much fuel... then when it got colder out, the car was still rich but not hitting fuel cut and not stumbling as much.. I don't get it, and it's also fine when it's like 80-90 out or something like that.... I guess I just need to do some fine tuning for 60-65 degree weather??

Pretty sure I saw someone on here with those, but doubt they posted a map.
but HKPRO5, ya I will hopefully at least be moving down to FL by the end of the summer, maybe Cali. depending on where I can find a job, should be fun though at the end of May I will be taking the car across country on a road trip, kind of feel bad adding so many damn miles to the car, but I wouldn't want to do it in any other car

So something weird happened today.... I have had a pretty decent tune at 10psi nailed down for about 2-3 weeeks now. (Holding around 11.5 AFR's all the way to redline.) Got in my car this morning, and anytime I go into boost, the car pegs the wideband at 10. It's like it has completely forgot the tune. Haven't had a chance to hook the laptop up to it, but just figured I would post on here to see if any of you have experienced something similar.

yupp, sometimes it goes away, and other times it will stay pegged at 10 or so, I still am not really sure what is going on. if the temp. is different then when you have had your tune set at, then that is, (so far) my explanation for it, but other than that, not sure, last summer I was able to get it tuned well enough so that I didn't run into that problem, but I need to re-tune it this year, because when it's a little colder it's pretty rich most of the time.
Weird.... I ran the AFC with the stock injectors on the supermap for over 2 years without a single problem, no fuel cut or anything. This isn't gonna work if it just forgets the tune every now and then. Gonna go out and do some more tuning and see what happens. For the last two weeks, my AFR's have been solid day or night, hot or cold, so i dunno. Will post back with my findings.

Same here...I've been experiencing this since day one. I make it a habit of re-loading the map to help with this but I've given up on "tuning". I just keep an eye on my wideband ALOT which is very annoying and if ever I see something really ridiculous, I take mental note of the boost and rpm and I adjust it later on the couch...load it afterwards. I wasted alot of time and gas trying to fine tune this thing...one day got fed up and made my entire map sitting on the couch. Funny part is, it's the best map I've made...stays steady between 11.7-12.2 when it works..lol!
Guys, don't waste your time "datalogging" or trying to fine tune. If your above 11 and under 12.2 A/F in full boost...click save, load it and call it a day.

msp2k3 can you post your map here? im getting ready to get 440s isnt that what your running?

Yeah, im running 440's... i need to do some more work on the map because all im getting are 10's across the board when i cross over to positive pressure.... not sure why because last week, it was holding 11.5-12.2ish till redline all day long and its not like the weather has gotten colder. It's acting exactly like it did when I first installed the 440's before I pulled any fuel out.
If i get it running better i'll post the map up.... but in all reality, I couldn't use anyone elses maps on here, I had to create my own from the superstock map.
If I don't get it sorted out to where I like it, I'll probably be selling my AFC and J&S safeguard to fund a haltech or the like. I am very picky about how fluid my car runs and the AFC/440's just aren't cutting it right now.
