    WOT versus LockPin Timing When Cam Phaser OFF

    I have a cam phaser lockout installed, and so have set all the phaser settings in my tune to disabled.

    With this set that way, which timing table will WOT follow, Lockpin or WOT?

    Looks like it is tracking along to the WOT base table, but since both my tables by default were pretty similar in the upper airflows, still hard to tell. Wish we could log spark source.

    Can you just make tables both the same so you don't have to worry since they are locked out? Spark source would be nice.

    I have reverted to making them the same, but in other OS and tunes I have seen 3 or 4 lockpin tables, PITA to have to modify all them for a locked out cam. Was just curious.

    Why not establish a baseline for what you see with both tables matching on your regular tune, then change a specific load vs rpm range to be around 5* less than it was originally, one table at a time, and see what is logged afterwards to deduce which table is actually controlling things? Seems like it ought to be a pretty straight forward process of elimination.

    With a 1000whp setup at times only running 7-8* that’s not always a great idea.

    You don't have to run it in boost to determine which map is in use, though. You could do it in the lower RPM and Load range before the turbos come on. Just a thought, is all. I can understand not wanting further retard timing when it is already as low as it is, and at such a high power level.
