What does the Engine Horsepower Calculation do? And how do I use it? Does it display percent HP on the screen or what.

Do you have to have a MAP sensor to set up the HP calculations in the Iefis. Challenger 10.4. I'm trying to figure out how to use the HP and lop rop functions. I have fuel injected io360 engine. Didn't think I needed a MAP sensor so I didn't get the rdac with MAP.

ok I moved the 12volt in to the A1 pin and now the auto pilot engages and disengages as intended. Thanks. now for the other problems.

Yes I do have it connected to D1. I thought that was for digital. I have a hard time deciphering the instructions. There is so many different documents to search through. This has been a uphill battle from the start. But I am making progress just not as fast as I would like. I will move my 12volt in...

I moved the antenna outside the aircraft. No change. I put it back and made sure its grounded with the m...

I'm thinking my GPS antenna must be bad? I mean there is only the cable to onto the Ibox, right. What could be wrong? Its not picking up any satellites. What else could it be. Is there a way to test the antenna?

Rainier

I went and took a couple of pics of my screen. It says no GPS fix?

It does show Lat and Long and the Raim flashes between Raim and Alt I think. Should the GPS be set to internal or what?

Tasmag

Ok I'll try that when I go to the airport. I'm new to this Glass screen stuff. How can I tell if I have a good lock or not. it does switch between raim and something else . Is there an indication for lock?
