    So I am new to tuning. From this post I gather that the AutoVE tuning tutorial for LS1 Controllers is outdated? Is there a step by step tutorial for how to begin tuning. I don't really want weed through these 72 pages to try and decipher what is the latest method. Thanks!

    Yes, this is the correct and most up-to-date thread on the topic. You can still use AutoVE, but this is faster and handles the MAF too.

    The original post is good and has been updated for the most part. Different setups may need to be tweaked a little bit but you should be able to figure that out as you go. For example... I have LTFT disabled, so my closed loop histogram portion is based on STFT, not LTFT. I've also messed around and done it based on LTFT+STFT combined.

    This is a great method for a MAF car because you can correct MAF and get a decent VE table in 1 log, without having to run open loop etc.

    Nothing beats doing an AutoVE to really dial in the VE table with a wideband....but generally CalcVET is more than sufficient.

    My car is speed density, but most of the time I still use the logic here to correct closed loop stuff with trims and WOT stuff with wideband. Again just to make it easier and more simple driving the car around like I normally would. You can tweak and combine methods as needed to suit your needs.

    Does this have to be competed in V7.5? When I try to connect I get the following error:Click image for larger version.

    It says I have the latest versions installed.

    Have you plugged in your Flashscan to your computer, opened V8, and checked for firmware updates? Not software updates.

    Got it. I guess I didn't have the latest version of V8. After installing that it prompted me for another V2 update.
