I bought a Superships Flashpaq for my Jeep this past fall and had pinging real bad on the 87 tune, no matter what brand or octane gas I ran in it. I talked to someone there and apparently there have been several complaints of this on the newer Jeep Wranglers, so they had come up with a new tune to fix it. Well, mine still pings with the new tune but if I return it back to stock, there is no pinging, so its definately related to the programmer. I have always run Chevron or Gumout w/Regane fuel system cleaner in it before each oil change to keep it cleaned out and it gets run on the highway every weekend, so I don't think carbon build up would be a problem. The pinging has always seemed worse when my coolant temp was above 195, so thinking its heat related, I changed spark plugs this weekend and went one heat range colder, my thinking being the advanced timing the programmer is creating is also creating higher combustion chamber temps.. Well, this helped tremendously, but I still have a little bit of pinging under light to medium load at certain rpm points. Would it be safe to go down another heat range? I have no fouling on the new plugs, so I'm thinking this would be safe, but it also seems awfully extreme to me for just a programmer and a drop in AFE air filter. Superchips has told me that theyve found its mostly a state related issue... any state that has california emissions seems to have the pinging problem, PA where I live, being one of them. So do I go down another heat range or just suck it up and run higher octane with the 87 tune? Stock, the jeeps come with a Champion Double Platinum 7570 and I changed to a 7032 which seems to be used mainly in the chrysler 2.7 v6's.

Have you tried it on 89, does it run without pinging?
Most every hand held tuner I've ever had recommended premium fuel.
But then I've never bought a superchips.
I'd bump the fuel up a grade and if it solves it, great.
Does your tuner let you adjust mixture and/or timing?

The OP mentioned any octane, so I'm assuming that means 89, 91, perhaps 93 if available in the area.
Is the tune really an 87 octane tune?
When you've tried the higher octane fuels, have you filled the tank, or just added to a tank of largely 87 octane?
If it's something happening only to vehicles with a California type factory tune, perhaps they don't have the tables correct in the tune?
What are you hoping to accomplish with the new tune? Seems like it's probably more trouble than it's worth at this point.

Its a programmer that has a 87, 91, 93, fuel mileage, towing, and crawling tune (for use in low range). I've tried full tanks of all grades of gas. I like having it cause it improves on the dismal throttle response these things have, I like the way the automatic shifts with it, I can use it to reprogram my tire size, and turn off my tpms. I could really care less about any performance gains with it, but unfortunately it doesn't have any kind of tune that just improves on the transmission shifting and throttle response while leaving the fueling and timing stock. And no its not adjustable, not by me anyways. They would almost have to create a custom file for me and I would have to upload it to my programmer, but that would be hard to do without dyno time and I don't have the money to spend doing that.

I'd use higher grade fuel and the stock heat range plugs.
[unless you vehicle is known to use too hot plugs from the factory - very rare nowadays]
I believe the end result will be no pinging with improved power and gas economy. What you pay more for in fuel will be offset by the performance and economy increase [to whatever degree].
And maybe a new thermostat is a good idea. Not cooler necessarily, but new and operating correctly.

Does it ping when using the correct fuels on the 89,91,and 93 tunes also?Or does it only ping when using any fuel on the 87 tunes?
Is the vehicle rated to run on 87 from the factory?
