Replacing Duramax Injectors

Just a few shots of Duramax injector replacement

 

Duramax fuel injector

 

Duramax injector sleeve…occasionally the injector is seized in the sleeve and the sleeve comes out of the head with the injector…..no biggy, just have to separate the injector from the sleeve and reinstall the sleeve into the head with new o-rings.

Programming and Tuning

We have the GM Tech 2 factory scan tool and can do factory programming, re-flashes and programming updates….

We also custom tuning with EFI Live…..

Here’s a short clip showing me commanding the FRP to 130 MPa and the actual pressure closely following the command thereby confirming that the injector replacement just performed did in fact correct an extended crank/no start condition the truck came in for…..

Here we are installing a 5 position switch and upgrading the PCM operating system to accept 5 separate power levels that are switchable on the fly.

Here the switch wiring is being ran and the pins installed into the PCM connector....Here James is running the switc wiring and installing the switch....Here I'm doing the operating system upgrade and the tune with EFI Live....The PCM is being flashed with the new operating system and tunes....And here is the switch installed....

 

Here is a clip of the same truck we tuned with EFI Live and installed a 5 position switch and custom operating system. The audio is VERY poor…my GOPRO camera was freaking out, but there is tire fryage going on! Settings range from Tow Safe up to the max power you want to make with a stock transmission.
