i'm with chris on this one....at high boost pressures you need good race fuel tuning as pump gas really defeats the purpose and puts your engine at risk the fuel/ignition maps will be very specific to your set up..
An ignition Map would be good to have closest I saw was a Fuel Map that has been shared for 1.7 bar by Dimitrj from Siberia this was for a 4e at 10.8 afr with 9.3 CR stock pistons & rods and 98 ron said he removed a lot of timing.
Dimitj's boost map has fueling to 1.7 bar, if this fuel map could be extended to 2 bar that would be 10.2 AFR .
For timing Dimitrj was using a safc2 monitoring a knock sensor I dont know if this would get you to 2.4bar and as Chris says no timing at all is on the cards.
I am familiar with Dmitry) We were neighbors)
This year we were able to raise up to 2.9 bar boost at 98 octane.
But the car, which was a Safk 2, boost controller and the injection of methanol. Engine alive) Engine 5e gtx3076 turbine, pistons g16b.
Which head gasket was the car running
