I feel quite confident about the HP/ Fuel Flow and BTU stuff. However, I know the cooling stuff needs more work and I probably need a bit of help on that end of it. But, then it is simply a mathematical model and there is LOTS of real real stuff it does not take into account. However, as I said I have been pleasantly surprised at how close it seems to track with actual experience - perhaps something to be said for simple {:>) With the data that we are nowgetting, I should be able to fine tune the cooling side a bit more.
