e38 2bar sd

[b18cls1]

from my understanding to use the 2bar setup, i have to edit

b2101 and set it to 188 for the 2bar
b8103 and b8104 and generate the 2bar coeff,
disable the maf with the fail freq ect like the ls1
and thats it?

also can ltft and stft be used with no maf?

Thanks

Yes to everything except B8104 unless the engine has a variable length manifold fitted (B8026 will tell you that) :)
Assuming the MAP scaler is correct for your 2 bar MAP sensor, but 188 sounds like the typical number.
Also increase B8034 to the level of boost you expect to see.
If you want to get real adventurous then redo all the MAP zones too (B8021), by moving the MAP zones around to better suit the engines operating range you will have much greater mapping control of the Virtual VE Table. However, by changing these values the entire Virtual VE table will take on a whole different shape which is probably not too much of a problem given the engine will need the entire VE remapped anyway.

Parameter: B0141
Set all cells to 14.63
Parameter: B0143
Set all cells to 14.63
Parameter: B0146
Set all cells over 80’ to 1.00

should i set everything to 14.63 then set the open loop fueling to 11.8 in the boost region and set b0146 to all 1 or or set 14.63 then use b0146 multiplier like it is used in the stock tune, then tune the vve tables using the ben datalogs
