Up until recently, it was not feasible to implement replacement/augmented dynamic spring forces in TelemFFB for DCS because as soon as you seize control of the spring effect, you are now responsible for every effect that leverages the spring, including trim forces. With the lack of detailed telemetry from DCS, it’s not possible to do cleanly.
With features in the latest firmware, I have some ideas for an advanced spring override that will allow DCS to retain control of the spring effect for trim, but allow us to augment/adjust the applied gain (using same concept as the setting in configurator, but tied to airspeed telemetry). There is also the fact that both IAS and TAS telemetry are bugged/wrong in DCS.
Bottom line, this would be best addressed by the module developer. HB knows how to do it (F4 is a prime example). That said, I have no frame of reference on how the 14’s controls should feel IRL.
