Pinging at high RPM's
Guys,
I was getting on it pretty hard yesterday, and I noticed the car "pinging" pretty bad at higher RPMs. I'm running 93 octane with a 93 octane tourque tune from Tillman. I might expect to hear that with a low octane fuel, but not 93 with a tune.
Any cause for alarm? Perhaps I need to get the tune adjusted or something, cuz slowing down isn't an option
Thanks!

I'm not sure. The week before I filled up on 92 octane accidentally. One of the gas stations I go to all the time switched for some reason. However, I ran the tank down to under 30 miles, and filled up with 93.

I have to second that!!! Pinging isn't good regardless of who's tune you are running. Check the quality of the fuel you are using first. Take it easy until you find the problem. Pinging is "Not Normal" regardless of the tune you are using!!!!!!

Try running it easy until you can fill up again and see if it still does it. If so, you might need a little adjustment on the tune. You can also retard the spark a little until you get the next tank in. That should keep it from pinging, and you can still get on the gas all you want.

That's really irregular. I left the end user adjustability on the XCal2, for now you can go to reload the tune like normal. When it says Change Optional Parameters hit select. Go to Spark from 4000-up and knock it back a degree or two and hit select. Then hit cancel, and select again to save. Then select again will reflash with 1 degree less up top. Adaptive learning should have taken care of it, but it's possible the gas was really bad.
We have a Sunoco up here that's 99 times out of 100 the best gas in the area. I filled up with their 94 and my car was going nuts... I found out that the owner was mixing 94 with 89 and selling it as 94.
Let me know if it goes away... if not we can datalog SPARK SOURCE with LiveLink and send me the datalog.

Granted....
But in Tennessee, it's almost ALL corporate stores.
Exxon station are owned by Exxon and pump... you know it...Exxon gas.
Shell...
Bp... all the same.
But here, I have noticed many stations, even the brand name ones will sell you the flavor of the day.
Chevron in DFW seems to be corporate as well as MAYBE Exxon.
Shell is absolutely garbage.
As for the Sunoco story above.
Most gas is mixed...
Midgrade is almost always a mix for premium and regular. 50-50
I lived in Philly years ago... our Sunoco sold 104, 100, 94, 89, and 87.
I saw a tanker driver and asked him point blank, how they could possibly ship so many combinations. Did his truck have seperate compartments or something?
He explained to me that they only ship 2 fuels, the 104 and the 87...
Everything else was achieved via. ratios.
True story, but he coulda been BS'n me??

Will you lose any over-all power by backing of the timimg a degree or 2? Also with this blistering heatwave the entire southeast is in right now, is it ok to keep your tune like this? just curious.
