Diablosport Forums

I bought a Predator U7146 a few weeks back from Ebay, I had diablo sport unlock the device and I updated the firmware to the latest available.

Two weeks ago I purchased custom tunes from Bama/American Muscle, but I have not been able to upload them to the tuner.

The device connects to the Downloader 2.2.2.11 it goes through the whole upload process, but when I connect the tuner to the car only shows what seems to be the tune that the original owner had on the device.

Should it list the three uploaded files on the screen for me to pick which one I want to apply to the car? I am completely lost here.

Thanks for the help!!

what tunes fo you see onthe device inthe car?
Are you getting a confirmation from the tool that the custom tune was uploaded successfully?

on the Menu only shows the option "Custom Tune" sometimes says "Performance Tune". I think it should show me somewhere an option to select the tunes I uploaded to the device, right?


Yes the downloader application says successful and the screen on the tuner says Import OK...

Any ideas?

when you see customtune, the file is loaded and ready to be loaded to the car.

How do I pick out of the three uploaded tunes? I do not see them listed. From youtube videos I saw online I see the three octane tunes listed on the screen and then choose the one I would want to upload to the car's ECU depending on the gas I am usong at the time.

what vehicle is it?
we dont offer 87 tunes for the Mach1 or any 4 Valve...

Is a 2004 Mustang Mach1. I got 3 tunes from the guys over at American Muscle

On the downloader they said: 87,91 and 93 octane tunes

that tool will only hold one custom tune so you'll have to load one at a time and use the one you loaded.
