Extreme Power Puck installed on a Cat C7 engine

[Socaldefector]

I installed the Ext power puck on our motorhome with a cat C7, first of all the instructions are not all that great, in fact it's a guessing game, if it wasn't for some other post on here I wouldn't of been able to locate the sensors needed to plug into. I am not 100% sure if I have the right sensor on the manifold (map sensor) So being uncertain if I am on the right sensors, its hard to tell if the Power Puck is working. Typcially we have been able to run about 80 mph, this is all i have to go by, with installing, we are still running 80mph, does cat have an over fuel protection that could be cutting back? When moving the dial there seems to be no difference in power, or fuel mileage increase.

OK, that is the correct unit, so lets make sure you have it all plugged in correctly.

Be sure that the MAP sensor connector is located in the middle of the harness and the Fuel Pressure sensor is located on the end of the harness, and that they are plugged into the appropriate sensors.

OK, either you have a bad connection on the MAP sensor, it could be plugged in upside down or you did not plug in both the male and female sides of the harness. A lot of people will only plug into the sensor and leave the factory harness unplugged. I would make sure you have both male and female connectors plugged correctly. The reason I say this is because the IAT (Intake Air Temp.) is on the same connector as the MAP sensor and loops from the male connector to the female connector. It does not go to the board.

Hope this helps.

I will double check the connections,
However do you have a better Diagram of where you plug these into? I want to say that I have the map sensor plugged in and all the plugs are on correctly. Now is the map sensor plug the plug closest to the back of the motor?

Take a look at this diagram. The two locations you need to plug into are circled. The wires on our harness are not the same color as the ones on your factory harness. Hope this helps.

Thanks for the pic I will check it out. This being in a motor is kind of a bear to get at...

I replied to your email, it looks like you had it wrong, check it out...
