CM870 Turbo controller I recently discovered that my turbo controller on my 2006 International 5600i had no air pressure regulator and was receiving a full 120psi air pressure from my tank. I checked the output to the actuator and it was getting 90psi. I added a regulator on the controller input side and adjusted it to 90psi. I'm still getting 90psi to the actuator and if i adjust the input regulator up or down in pressure the output is what ever i adjust the input to. I'm testing with the truck running at idle. Am i doing the test incorrectly or is it safe to say the controller is bad? Do the controllers on these engines have to be calibrated? The truck runs okay but i am seeing some black smoke from the exhaust when loaded and i'm only getting about 32psi for max boost. I have pressure checked the entire engine and replaced the CAC due to a leak i found. | |||
