I did the ecotune from GDE and for a day or two it was great! But then the car goes into limp home mode occasionally (again) and the following codes popped up
2513 inlet port motor positioner indicates fault
(that popped up before every now and then)
C100 no can message received from engine management control unit
4759 adaptive brake no can message
9204 control unit ASSYST is not receiving any messages from engine CANbus.

Has as anyone else had this problem?

Never had anything like that. Sounds like something else is going on. I would email green diesel and see what their thoughts are. They have been pretty helpful with me. I currently have a dpf code stating below threshold even though I don’t have one. I think there may be an issue with the harness I noticed some chaffing where it had rubbed against itself

hopefully you get figured out. I know it’s annoying.

I’d like to find a mechanic that will do the r and r for the modified manifold without flaps but I’m having a problem finding anyone

Yeah that is probably a tougher find. I think I have one lined up. Last I checked cb was waiting for some donor intake cores. Hopefully he has some in soon for you. I plan to do some day when the seals leak a bit more. It’s a proiority thing with this car. Right now tires and tranfer case have to come first. Case only makes noise under heavy corner acceleration so waiting for it to be more regular. I just had all the trans and diff fluids changed including tc and they seemed ok. I change every 40 and tc 20 when fuel and air filters changed
