Hi,
I have been doing a great deal on research lately on injection timing as I am about to install and tune a BTR stage 2 NA cam into my Clubsport R8 LS3 (specs attached). Thanks to this forum and its contributing members, I feel like I'm starting to get a grasp on it but would really appreciate it if someone with a solid understanding on injection timing could take a look at the attached spreadsheet and let me know if Im on the right track or perhaps suggest any changes.
Thanks in advance.
Updated to the latest spreadsheet attached.
Try advancing the whole thing 20 degrees and then don't go to the final 590 until around 5300ish

Thanks GHuggins, I was actually hoping you would see this. Does this one look more like what you would aim for?
Looks a lot better, but play with it and see what the engine likes... Injector sizing and build setup controls injection timing as much as the cam profile does
