Trying to get the timing set correctly, but i ran into a slight issue. Because of the altitude my map reads about 12.3psi key on engine off. The issues are that the columns for Boost VE table and Boost timing table start at 15.2psi, at this point i am already making about 3psi of boost.
This is my first car tuning on boost, but i wanted to remove timing slowly till i got up to full boost ~8psi for now). The problem I'm having is if i pull like 5 degrees of timing out at 15.2 (3psi boost) there is a sudden drop in timing. it is not scaling the timing when moving from table to table like it does moving from cell to cell in one table.
Do i simply pull timing from the high octane table so it is lower when it enters the 15.2psi map reading and is a smoother transition?
People always talk about the timing they have on their engine, but it is at 100% throttle and max boost. How much timing is safe to run at lower rpms and lower boost levels before you hit full boost?
