got my jlt and x3 today from american muscle. ordered a 93 race tune and a 91 performance tune. im running 93 octane in the car and im detonating with both tunes. any suggestions? Is there anything i can change with the handheld or should i wait till bamachips opens in the morning and call them?

I'ld wait till the morning to be honest, however if you can't resist try lowering the timing by 2 degrees at a clip in the RPM band where she starts detonating.

Did you run through a whole tank of 93 before you put the tune in? What were you running before? If you were runnning a lower octane and then filled up with 93 and put the tune in, it could be mixed and have lowered the octane rating so that you are getting detonation. Something to consider as well...

I had less than an eighth of a tank of 87 when I filled up with 93. It even pinged on my 91 tune

That could be your problem, run another complete tank of 93, on the next tank then try the original tune settings, start with 91 and on yet another tank try 93 just to be on safe side

You need to flush the 87 out of the full system...

Talked to dan at bama he said fuel wasn't the issue. They sent me some new tunes. All is well

I had about an 1/8 of a tank of 87 in mine when I filled it up with 93 on Friday night, honestly I was a little concerned that the little bit of 87 left in the tank would possibly change the octane level of the 93 I just put in, and installed SCT/SF3's 93 tune on Saturday, and I have not had any detonation or any other adverse affects, thankfully.



Glad to hear you got it sorted out
