how to estimate parameters for oscillation data with ODE system model

I have a system of 17 ODEs and 38 parameters. I am trying to find the values of the parameters to get the ODEs to oscillate. What is a good way to do this? This is a biological model, and the ODEs are based on biological processes, so I can't manipulate the model. I had it oscillating previously, but the parameter set is unavailable (it was a GUI which finally crashed completely).

I am thinking maybe I can curve fit to oscillation data? However, the specific values of the oscillation are not important (ie, x or y values would not need to be fit exactly).

Thanks for any suggestions!
