since it can't control boost and it's running out of fuel control that
the ECU is changing the timing to try to eliminate the knock. Changing
the timing could cause a reduction in boost.
I, personally, would not subject my motor to this configuration. You have
essentially set your base boost to 1 bar (or higher) and disabled boost
control. Looks like perfect conditions to get big holes in the piston tops.
I know the MBC is cheap, but spending $7-800 for new software from a reliable
tuner is cheap insurance and you will get more power than with the MBC.
P.S. An Abbott reprogramed ECU raises the base boost to 12 psi and is just a
little bit safer than your set-up. Ask me how I know.
