Need help. Loaded New SCT SF 91 oct tune on 03 GT

[GTR_Stang03]

Using the new SCT SF Tuner, I loaded the 91 oct tune to my 03 GT using 92 octane gas. The car runs great with the exception of some pinging when I goose the throttle at at a stop (neutral). It happens at the beginning of the rev. What can I adjust to get rid of this?

The mods on the engine are: Ford Racing CAI and BBK 75mm TB and Plenum.

Experienced SCT SF 2 users please.

Thanks.

Back the timing 1 degree then take her for a drive again. Repeat if necessary.

Try pulling timing back a couple degrees form the 0 to 2000 rpm range. I had to do the same thing. Mine would ping in high gear below the 2000 rpm range. I max the timing out throu the 2000-4000 range and 4000-6000 range. Pearl02.

Thanks. I will take 2 deg out of the 0-2000. I will let you know.

Thanks. I will take 2 deg out of the 0-2000. I will let you know.

I origanally pulled 4 degrees out between th 0-2000 rpm range. Once I got my gears in, I was able to add 2 degrees back. All I'm saying is you may have to pull more tining out. Play with it. If only I can get my data logger to work. Pearl02.

leave the timing there ... add some fuel in the low rpm trims

My car has started to do the same with the 10% etathanol gas stations are putting in. I'm running the 87 octane tune to stop the pinging while I find the solution.

whats this thing goin around about this new thing of 10% ethanol additives put into the gas??? its always been that way for me in NY..

im having the same problem, and I think this ethanol in fuel crap has something to do with it. I fill with 93 octane and it pings with my safe (87 octane) tune at WOT. I pulled timing and went richer A/F @ WOT in 2% increments until I fixed it, but depending on where I ge gas at, it comes back. I used to have 1 gas station that was always reliable for good fuel, but now its hit or miss. this blows.

Got it...! Took 2 deg off @ 0-2000, added fuel @ low trim, and added 5 % @ Wot for CAI. Works GRRREAT!!

This is with 91 Tune.. and our Western 92 Premium Mobil 1 Gas or Shell which ever one has an open landing strip.....

Thanks, Jongo, for the fuel tip!!!!!!

Glad it worked out for you. I didn't think about the fuel trim. I'm still fighting with my data logger.... Pearl02.
