On the 93 octane race setting I'm getting ping under load pretty much all the time once I reach operating temperature unless I drive really gentle. Not horrible ping, but it's there.

With the other two settings I get ping only for a split second when I am cruising along and all of a sudden punch the throttle. It's not terrible, but it's still there and that's not good.

87 for the 87 tunes and 93 for the 93 tune.

even running the 93 though I get some split-second pinging when I suddenly goose it even if I'm running an 87 octane tune. At least I think it's pinging. It's a momentary "clattering" sound.

I don't get it at all with the stock tune. Even cruising around in 4th at say 1500rpms if I nailed the accelerator I'd get no pinging at all, but with the chip tunes I get it when I suddenly hit the gas pedal, unless I'm cruising at a higher rpm (2500 or above before I push the pedal hard). Even then on the 93 octane setting I get ping no matter what, any time I push it hard I get continuos pinging.

If you run 93 with the "91" or "87" tunes what happens? Have you fully flushed the fuel tank of the "mixed" fuel by running through a tank of 93/?? mix before trying the "93" octane tune? It might not hurt to disconnect the battery for 5-7 minutes to clear the KAM (long term fuel trims, and other adaptive learning stuff).

Also, a comment was made in a previous posting that the "SCT tunes" should have the fan set for a 180° t-stat--if this were so then with the stock thermostat the fan should be running non-stop, all the time the engine is up to normal operating temperature--does it?

When I ordered my chip Bama asked what t-stat I was running, I said stock so I'm sure it's set for that.

Even running 93 octane on the 87 Street tune I get some very mild pinging when I suddenly give it some gas.

I'm thinking I'm going to have to go with a handheld unit so that I can make minor changes to the tune myself.

If you are getting pinging on your 87 oct tune with 93 in the tank.....call BAMA and tell them to fix your tune. There are a couple other possibilities to consider first......
1. what you are hearing may not be pinging, have a mechanic listen to it.
2. like nick said, you maf may be dirty or some other factor may be causing your car to run lean.

You might also want to hook your SCT tuner to the car and datalog during this pinging to see what the fuel trims are doing and to see how much timing your car is actually seeing.

It's not a handheld, it's the chip. Also I've cleaned the MAF.
