Chopperdoc tune
 

I was trying to make a tune off his video but the pages that come up are different than his. I was clicking on what he did step for step, but when he got to open/closed loop mine just showed open loop. Can anyone help me figure this out. As you can tell this is all new too me. Thanks

Some of the OS's look differently. Some have a actual button that you can force, others you just have to adjust in the tune. Either way will get the same result.

Yes the tables can be different between OS and also the versions of the software. The physical tables in the tune are still the same in most cases, just in different locations on the tabs. When they changed the software from 3.x to 4.x they added an “oxygen sensor” tab. Still the same tables, just relocated a few things. I’m sorry it was confusing a bit on that. If the tab is different for some reason just click on the other tabs and look for the table.

So to start with I need to go to the OS tab and click on the 1 bar maf or speed density enhanced? Thanks for the help as you can tell I need a lot of it. I just done a LS swap 1970 442 and after a year, i'm ready to get it going. I was going to take it and get a tune but I know I will be changing stuff on it and need to learn if possible. Thanks

What table are you trying to find? What is the goal for the tune? Are you going to run speed density or MAF? You don’t need to change the OS, depends on what you’re trying to do. You can’t undo that either so make sure you back up your file somewhere and use the “save as” function. Also, what PCM are you working with?
