It's not realistic for a lot of people that daily drive to log their cars even weekly. Monitoring is still a good way of getting advance notice that something could be wrong. I always pay attention to the monitor see the odd -1.4 FBK when puttering around at low RPM and usually when I am at a green light where I see I can get a good run I will reset the monitors and do a hard log-like pull and if there's 0.00 FBK I'm satisfied. I do most logging anytime I change a tune or the season is changing but once I feel comfortable that things are okay I don't spend too much time overanalyzing as it kind of takes some fun out of the car if you are always thinking about it. Not saying it's never a good idea to log but it's just not something I feel worth being done weekly.
Generally if you have been running the same tune for a long time and the logs have been consistently good what's to be overly worried about unless you are filling up at lots of different gas stations and varying octane ratings? I fill up almost exclusively at the same gas station and I find things are pretty consistent and as long as I don't see abnormal knock activity I'm not terribly worried.
Awhile back, I was live monitoring once and didn't even know I was suffering from a significant amount of small knock counts. I saw the peak count under the gauge while I was driving and assumed it was occasionally knocking because I couldn't see the numbers on the FKL counter changing (because I was too focused on driving the car). But I felt timing being pulled once and thought that something was amiss. Fortunately, I was also datalogging...I checked the logs when I got home and there were knock events all over the place (small but a lot more than normal). I'd have never known if I hadn't been logging or had the urge to even log. IMO, this is what gets people into engine trouble later...they become to complacent and dependent upon live monitoring.
From my understanding of gas stations, most of them aren't consistent with the quality of gas. You might get good gas for months, then get a random bad batch. If you haven't experienced that yet, you're lucky...eventually, it'll happen. I also believe that not all protunes are rock-solid...there have been plenty of guys that have spent tons of time and money on parts and tuning that ended up with blown engines.
Also, I never said for anyone to log weekly (each Scoobie owner will have their own interpretation of what is excessive), but monitoring every tank of gas (a 10-15 minute log should be enough) shouldn't be difficult...that's 10-15 minutes of logging during a 7 day period. Some people take dumps that are longer than that...that's really not a large amount of time.
No matter how you cut it or what your personal life entails, live monitoring is never going to be a viable replacement for datalogging, unless you've 200% trust in your tuner (and you'll never know your tuner is doing a good job unless you check, and that requires datalogging). Each of us have different priorities and wants and needs, but IMO, if you can't log and check them occasionally, it might be better to stay on the stock tune or ensure your tuner has taken every single factor into account, but even then, tuners aren't created equal...some are better than others about giving you the most bang for your buck.
I believe people are blowing engines because they're becoming too dependent upon the live monitoring features of the AP. I've lost count of the times someone opens a post saying that they're seeing knock but will only post a picture of the AP's gauges as supporting data (and you have to grill them to log).
Apologies for responding with a diary, but it's all relevant.
