To the OP, glad to hear you got it sorted to your satisfaction.
I have to admit I'm a little confused though by your conclusion that the IBC eliminates the guessing compared to the prodigy. I use a prodigy P2 in my Nissan, and a Ford IBC in the F350. As far as inititally setting them up, I use the same procedure for both. Once I have determined what the appropriate gain setting is for each truck, and each of my four trailers, I simply ensure that value is set on the controller when I hook up.
They both work, each and every time, with all four trailers ( assuming good electrical connections and brake adjustment ).
The Ford IBC is "smoother" in operation, I will agree with that. But they both work, whether stopping normal, or stopping hard. In fact, with an aggressive "boost" setting on the P2, I actually prefer it's feel, especially on a hard stop. I can really feel the trailer hunkering down, and the whole combination comes to a forceful, controlled stop.
Again, glad to hear you got it sorted. To any new folks who may stumble across this thread, my comment would be to you if you are considering a Prodigy controller, go for it. It's a good controller that when correctly adjusted, works well ( in my experience ).
It is I suppose possible that some who don't like the prodigy never managed to get it adjusted correctly. It comes with well written instructions for set up. Follow the instructions step by step, and it will serve you well. In my opinion.
