Need help. Recently tried to install the Gear Box Z 4.0 dpf delete and it would download for about 20 mins and then say error code 88. any help thanks

 

I think you need to contact gearbox z on this one. There are several that have the DPF R but no know has ever indicated any problems that I am aware of.

 

I would contact Gearbox on this. I had an error code when I tried to install mine. I called them and they told me to turn the key to the run position before I plugged in to the diagnostic port. I did and the programmer loaded.

 

When I put mine in the voltage was low. I put a charger on the battery when I did the download and then it worked.

 

I used a gear box before I got my sct and it came up with an error code. Cant remember the exact code but I called them and they sent me a new one over night and sent them the old one back. They will take care of you.
