Hp Tuners LS1 speed density mode

Hi,

So I have pulled a stock file from an LS1, I saved the stock file and applied the HP tuners speed density operating system fulr, re named the file, all good.

But now when I go into the speed density file and click on operating systems it is completely blank. It has however given me my second VE table. I just want to know if this is normal before I flash the base SD file back in and start tuning?

I've have done the reflash course and I'm aware there are slight differences as this vehicle is alot older then the one in the demo.

Bit of piece of mind would be greatly appreciated.

P.s the operating system files I had available for the vehicle were all RTT files, not sure if that makes a difference. I didn't have any other choice. I chose the 1 bar SD file as it's completely NA with an OTR and exhaust.

Hey Damien, this is normal. Once you've applied an OS patch you can't apply another OS patch without reverting to a stock file. Perform a write entire and you should be good to go.
