I just toasted the ECU in my ‘93 Civic. Capacitor C27 for the fuel pump fried! I plan to get a replacement ECU. What type of engine management/ chip are most people running with the JR supercharger? I’m thinking Hondata S100. What size injectors 440 or 525? This is a JDM B18c, 11psi boost, 68mm TB, header, etc. NOT a track/race car. Before I throw another ECU in I want to make sure something else did not take it out, Honda will not tell me what else the cap controls in this circuit. Does anybody have any info on the inside of a P72 ECU? Has anyone had this problem?

 

Me too I want to make sure my wiring is good before I throw an ecu at it and blow it up too.

 

Those ECUs are getting old and caps are starting to fail, just replace the cap.
