Replace your power supply cap (C14) before you have to replace your ECU!!!

Post by RyanA »

Just figured I'd post this since it appears that most people, when they socket an ECU, just put in the components to enable a chip to be installed. Besides installing the socket, the 373, 2 caps, a resistor, the datalog port and removing one jumper to move it elsewhere, you should also replace the main power supply capacitor at position C14. It is a 220 uF 35v piece. I typically replace it and upgrade it to a 50v piece. Here are some pics showing the cap that needs replaced. Also attaching a couple other pics of what gets done to the rest of the ECU.

When you buy a basic socketing kit, it does not include this cap. If you buy a Hondata S300, it does come with it.

ECU after being socketed with a tooled pin socket. Also set up for datalogging so the jumper is removed and the datalog header is installed. This ECU used to be an auto ECU but I desoldered the resistors in RP17 and RP18 and then added a jumper in RP18 to make it a manual ECU.
