Well, the K-pro that I have, its only for the Greddy kits,It will be out soon. About you using the rev hard one, I wouldnt do it but its your car.
My question is, why do you have k-pro and dont have an IC? I recommend you to get an IC to get the full benefit of the k-pro.
So in conclusion, just use your emanage until you get an IC and K-pro.
