i was on a dynotuning for a couple of weeks ago, the tuner didn't have so much experience of neptune. so the tables didn't look så nice when he was done.
the question!
does it matter if the fuel and ignition tables are a little messy? the lines cross each other on some places,

the car runs smooth and i don't have any ignition problems

 

It would run smoother if they didnt.

 

lines should never cross. in the ignition and fuel tables tables, lines may meet, but should never cross.

 

maybe your tuner just tuned the part that you dynoed. like WOT only, in that way, line might cross usually. unless he guesstimated the cells in mid load.

i agree. lines should never cross.

 

yes it was only the wot tables that was tuned, it got tuned from 10psi to 23 psi
