When I first arrived in the UK I took my 2010 SS to a local shop where their tune guy had LS experience. I asked them to look at the tune since I was now at sea level and they use 94 octane fuel.
Flash forward 4 year add supercharger and I read tune in the SS in prep for tuning. I noticed that it shows two controllers. I have the E38. What is this Holden controller? See attachment.
I sent this off to be modified for the FI setup. When I went to write it to the SS, I had to licence it and it used 3 credits (on for the Holden controller) and listed the Holden controller as "Brickable" so I did not select it for write to the car. The E38 flashed just fine. But now I am wondering if some how this Holden reference is tied into the tune. Do you thing it made its way from the UK shop when they worked on the car? They were using EFILive and the LS3 cars they work on are Vauxall VXR8's.
Wondering,
Dan
