the function of capacitors is to filter voltage which operates on the ECU board and powers up the microprocessor, so if one or more blows up and the unfiltered voltage reaches the microprocessor, its frying time
my suggestion is for you take out the ecu box, if you're not mechanically inclined, take it to those hole in the wall tv repair shops, ask them to identify the capacitor specs, if they don't have it in stock, buy them at deeco in raon, ever gotesco commonwealth, or farmers cubao. then have the technician desolder and solder the capacitors for you. though i haven't done this since i went the DIY route b4, i'm pretty sure the tv shop would charge you lower compared to what they would charge you in banawe.
i'm no expert, but imho ECUs are just like our PCs, the same architecture. Its the software and processing power that varies. Definitely hackable to those who have the time.
