I am curious how your brother decided to replace the ECU. Did the CEL codes suggest it was failing?
When my ECU failed it came with many CEL codes all at once that included reports that all 4 fuel injectors had failed, which is a nonsense failure as this situation is statistically impossible. My mechanic said that multiple codes like this typically pointed to a bad ECU.
