Ok, I installed some SVO 42lber's. I tried to enter the values (from RedHardSupra' site) via HP Tuners it doesn't paste quite the same number into the cell that i'm copying. It's close, but a little less. I even tried manually entering each one and same thing. Car pretty much runs fine although it did backfire a little on the first drive, but stopped pretty quickly and hasn't happeded again. Any ideas and why the table is changing the entered values slightly? Also, I saw in a previous post about making sure COT and DFCO are off (I'll have to check this), but was just wondering why? Thanks.

 

it pastes fine, you just have a different precision displayed, but it stores the numbers precisely, don't worry

COT and DFCO are just another fuel modifiers, so but turning them off you're minimizing the number of variables affecting you're fueling
