I made a post a few months ago about tuning my 2009 G5 with the 2.2 LAP engine with a supercharger and LSJ injectors. I got good advice but now i'm stuck between Scaling the tune because I am using the stock MAP, or Buying the 4 bar MAP sensor from ZZP and not have to scale the tune.
To scale the tune i read i have to scale by 50% because it is much simpler to do the math. I have 61 lb/hr Deka injectors at 43.5 PSI so i will have to scale if I have the limit to 63.5 lbs. So i multiply the VVE table, MAF table by 50% and then adjust the spark tables as the cylinder mass will change. Is there anything else i have to scale? I know retard tables and other table that have to do with airflow will have to be scaled as well. But what do i do about VVT?
I have not pulled my stock tune out so i do not yet know if i have the 63.5 lbs limit on the flow rate or not. I will post my tune once work on it tomorrow and scale it by 50% to get some advice if i am on the right track. Just buying the 4 bar MAP and tune with it seems to be much more simple, But this is my first forced induction tune so looking or advice.
Thanks.
