Haven't extensively tested this. But if you need to convert spring inputs (tension, friction) between Framer, Quartz Composer, POP and Rebound you can find the formula here. I'll integrate it in a future version of Framer so that you can select "curve: 'spring-qc'" for your animations.

I tried to use your use but I got some weird values:
» tensionFromQcValue: 1339.4194
» qcValueFromTension: -44.75138121546961430
» frictionFromQcValue: 117625
» qcValueFromFriction: -8.3333333333333348
