Hello everyone!

I have an engine in which the limiting moment is known in advance at which the connecting rods begin to bend.

I want to make an ignition map in which, over the entire rev range, the motor would give out the limit values ​​​​of torque (of course, provided that the motor will produce torque in the right amount). Normally torque control is done through throttle control, but in this case I limit the amount of gas produced by the engine and as a result turbine spool

It is also possible to limit the torque through boost limitation by setting different pressure at different RPM, but I'm afraid that in transient engine operation the torque will be exceeded

The potential torque limitation should result in an increase in EGT, as the gases will do less work in the combustion chamber. How potentially problematic is this?

Does anyone have experience with this kind of work?
