So I grabbed a quick log of what the maf should look like at each rpm for idle with 18% throttle and then 100% throttle - So for idle you’re clearly WAY off. I know one bad maf can cause both to read wrong from what I have seen in the past.
I guess I should change the other maf cause it makes no sense at all. It has to be that I’m overthinking it
Hey guys I was using my bs scanner and I swapped the engine computer from right to left
I noticed that the code changed from maf b to a
Wont let me post other picture from some reason but It changed from maf b to a high circuit so I’m starting to think maybe the computer is bad.
I’ll check with the Ross tech when my laptop is alive but it’s starting to seem like the computers
It changed sides
Here’s a scan of it with the computers swapped

Hey guys swapping the ecu made a difference Now it’s saying 3g/s
Car seems to be running fine. I’ll let you know what happens tomorrow I’ll be driving 50 miles out to my school.
A good but bad victory… Good you fixed it bad to find out the ECU was damaged. This is a good road map for future issues like this. GREAT work.

Thank you and the car is running excellent. I’m thinking of getting the ecu fixed to be a spare if something happens like this again
Turned out it wasn’t the second ecu. I swapped that nothing happened so I started playing around. I put back the second one and tried swapping the first one and that did it
ECU #! is the main ECU if there is an error generally it will be in this ECU as ECU 2 is basically the slave ECU.
