LTFT and maft OK, so i´m trying to make a siple tune on my car with autotap and maft.
mods in sig.
So far my maft is set on (mafbase 25% rich and mafwot 8% rich) But i´m not really sure of how this works
My ltft on cruise are +6% and +13 at wot. Does this mean that if i increase mafwot, ltft on wot will drop?

You shouldn't take any notice of the LTFT's at WOT. The values shown in them is the value before you went into WOT. Really its best to not do any WOT tuning unless you have wideband, however people have aimd to get their O2's reading about 900mV's at WOT.

OK... on my last log the 02 were at 875-895mv until 4000rpm after that they showed like 935mv. My maft is set at +25% base and +12% wot
My LTFT shows + 4 at cruising and sometimes when give some gas it goes up to +9 .
Can i do anything about the LTFT to get it -? My maft i set at max now 25%rich.
And i´m thinking of setting the wot down a bit to get lower mv.
What do you think?
