Trying to create a High torque low Horse power diesel engine for the Hopper, I started with someone else's diesel I4 mod and modified the power outputs, the friction/inertia, and rpm to match what I had planned, A very torquey crawling/pulling engine. However, Now that the power is what I want, I can't get the engine to act correctly, It is either revving to the moon and spinning the tires, Or Twitching about and trying to die until it gets some RPM and picks up and acts normally. It also dies when light throttle is being applied, I added a huge amount of boost at 150 rpm to try to make it not die and it still does. (I think it's just due to the twitchy-ness of the engine.) Acts kinda like a real engine that is starving for fuel. I'm uploading a very short video right now that I will link in about 30 minutes (Upload speed is like 30 kBps lol) ---- Kept changing stuff and finally figured out what I had wrong.
