You can retard the distributor timing.

hope i dont have many problems tuning and installing megasquirt, as i see this is impossible to do without proper ecu tuning.

safc2 would work nicely under boosts till 0.8 bar i gess, but even at those pressures it wouldnt be safe.

good octane gas and cold spark doesnt garantee it.

Assuming you have a Honda, you would retard the distributor/ignition timing by pulling the distributor towards the front of the car. I have used the VAFC-1, and that's the same thing I did to mine. I had to retard mine to 7 degees BTDC to avoid pinging. FYI...I made 225whp/211ftq on a SOHC using this method.

As stated before a chipped ECU will yield better results.
