Default Do I need to adjust my ltfts again after battery disconnect?
Like the title states, I'm just wondering if I need to log and adjust my ltfts again after my battery has been disconnected? The tune has not been changed whatsoever, but I thought I read somewhere that power disconnect clears all stored ltfs. True?

Thanks guys

Thanks for the reply. Will they relearn to the -1 ltfts I had them adjusted to, or will I have to log/adjust again? Thanks again.

Yes, they should duplicate what they were before, all else being the same.

What he said. Long term trim is exactly what it implies. It is trim not setting. You are looking at what the computer is correcting.

Understood. I was referring to adjusting my injector slope.
