you can undo any changes made in quick tune by manually changing values back to what they were or use the restore defaults button.
if i go to the spark tab in quick tune and add 1 degree of advance in the low range and save that setting i will be running my tune with that adjustment.
when i am done i can go back to the spark tab in quick tune and use the reset defaults button or subtract the one degree of advance i had added.
either way you will have to save your changes for it to take affect.

I have also settled on a 14.2 based AFR table. I think I've got this part right as my lambda calc does not have CLB it has a CLLR,Closed Loop Lambda Range. I've set the high at .990 and low at .960 ,This is still within the range of the NB sensors correct?
I was also wondering about Quick Tune being temporary. Does it return to your regular tune on the next key on? or stick untill you reflash?
I havn't had much seat time lately with all the rain and a throttle problem (covered that nightmare in another thread) I'm still trying to tune out the vibration in my footboards by pulling timing between 2k-3k rpm. Log Tune is pulling very small amounts here and there like .013*-.050*but not in my problem area so I've used Quick Tune to pull as much as 4* from low and mid range without much improvement except when my ET is over 250*f, which is where Spark Adjust by Head Temp kicks in,If I'm reading that table right. from 60-100 map(kpa) from 1.5* to 2.5* which is where I start to get a bit confused, If I pull 5* next time that table is still there pulling more. should I continue as if it wasn't there. or should I manually pull some from the areas I'm feeling the vibes? If I do that my table wont flow very smooth.Am I making any sense?

Question on using PV Log Tuner to play with the spark tables:
Do you create a value file with only the spark tables check marked ? I tried this and got errors about the VE's missing.
I was just playing around with old tunes and logs from my Sportster. Waiting for the PV2 to show up in the mail.

Yes, pull it. Don't worry so much about the slope. back when things were mechanical everything looked nice and pretty because it all ramped up based on RPM and weights. Now you have 200+ cells. leave them as LT pulled and ramp up the surrounding cells until they also start being pulled. Once you're finished with that area you can tailor them DOWN to prevent any big swings. Just don't add any timing or you're back in the situation of pinging. It will interpolate regardless, so it will make up its own mind in the end. have a peek at a log and you'll see ex: 39.5 when you don't have 39.5 in any cells. All you really want to see is no big differences. I try to stay within 1 or 2 degrees. if a cell is outside of that I just smooth them in using .5 increments. You won't really feel it but it helps the ECM do its math. Just make a "save as" map to play with so you have a way of going back to a previous map. What I do is save my last AT run as "6ATlast good run". Then I do a save as and call it "6ATlast good run test". This way I can play around with the "test" and always keep my last good AT run unmolested.

Thanks stailjim61, thats what I was trying to say. when useing QT it pulls from those cells I dont need to. I was just trying small increments in QT to see when and where that vibration would end.I did a -5* pull in the low and midrange areas today and feels better maybe 1 more deg. tomorrow. then I'll pull 5 or 6 from the main tables in the rpm/kpa range I feel the vibes instead of the large blocks QT pulls.

Okay thanks I didn't realize there were check marks there. I'm still stuck with missing channel errors but I'll sort it out.
