Backed Vision timing 1degree back
So looking for some feedback from any Visionaries that may have had a similar configuration as mine and backed off 1 degree or more on their ATS if you felt a noticble drop in jump off the line. Specifically coming in at 2k through 3k.
Recap of my 2011 Vision configuration.
Lloydz ATS at 6
Lloydz upper filter
Vic performance on front
Intake boot (4 hole insert in the tunnel. Still installed
PCV no auto tune
Dyno by Lloyd fall 2013 at his shop (I'm at sea level)
Running 91 octane, no boost added to fuel since the last of the mods. As temps climbed into the 90s and if I was hitting wot 3rd and up I was getting occasional pings especially in 4th and 5th finishing out the acceleration demonstration in the upper RPMs.
Off the line this bike will almost give you roller coaster tunnel visision when you unleas it. However as expected the trade off was around 4500 she would level off. Expected since I didn't do cams. So to resolve the ping and keep the punch off the line and in 5th/6th on the interstate every day I tried octane boost. No joy. Could have been my ratio or my mind but didn't like it.
So, this weekend I popped the cover to back it off 1 degree after NewVic posted his pre mod numbers. To my surprise I was at 6 and not 5. Alsheimers must have set in because I swore I had backed it off before the mods. So feeling good knowing it was 6 I set it at 5 and was feeling great. Sunday/Monday no ping on my normal exit and on ramps nor 5th or 6th doing wot lane changes.
Today however I had to hit the back roads coming home as well as stuck in some traffic. Maybe it's my mind playing games but she did not seem as responsive under 3k as before.
Since I know the ATS also changes the injection point I am thinking of going back to +6deg. I can't seem to find where the PCV can subtract timing or if the is even an option. And if so does it make sense to do that since it will affect it over 3k which is where I get the occasional ping. I really am frustrated that I didn't back it off before the tune because I'm messing with the tune by doing this.
Attaching my Dyno and let me add that where she hits that 100 torque at 2krpm it is no joke. Hard to describe but she comes in hard out of the gate. Also, for readers benefit my highway riding is 65-75 everyday which is steady around 2500-2800.
Thoughts on octane boost, moving timing back to 6 or if the PCV can reduce timing.
