Hey All,
I noticed something very wierd the other day.
I tuned my vf22 to run 21 psi with WGS below 10psi. When im say in 4th gear 3k rpm getting on it and letting of suddenly i get knockin the 10% and 0% load columns.
Psi registers at 4-6 psi when knock occurs.
Afr is correct for those column and i want the stock ecu to be incontrol of timing in the 0% load column.
I have been able to cure this after set my WGS to 7psi instead of 10psi. (I know the other way i can fix this is by adding more fuel in the 0 and 10% load columns. But perfer to have my AFR hit my targets)
Anyone else come across something like this? I will post logs of this when i get back into chicago on Thursday.
