I an having trouble with my ecu again!! I just purchased a used PND ecu with kpro v4 installed, plug it in load my tune and car fires up for a little running rough and slowly got worse and worse. I even got codes p1361 and po344, and originally thought my cam sensors got mixed up, tried switching them nothing, then I slowly started to realize more were not reading like tps, map ect. Car is turboed and is k24 and has a trc wire tuck harness that is brand new. More back story on ecu, I plugged it into the computer and it just flashes the red light. any ideas?

Have you tried the ECU in a known working vehicle?

What is the serial number that is on the K-Pro board inside the ECU?

I seem to be having the same problem as well. I have a PND ecu too. And the car starts up, but idles very low. Cyclinder 4 does not seem to be firing at all. Check all my grounds. Bought a new tuck harness, I even swapped the crank sensor wires around and still. Replaced my injectors with oem ones brand new. I also tried swapping the coil packs around, that cylinder just ain’t getting no signal to injector or is very low in voltage.
