    Default ECU Capacitor Replacement

    G'day.

    Who besides TERRA Operative is able to replace capacitor's in ECU's please?

    I have somewhere between 7 - 9 ECU's, mainly 1G-GZE (twin boards), 3S-GE, 3S-GTE and 5S-FE that are old enough to have problems when I use them and I would like to fix them before I try.

    Thanks.

    AFI (Australian fuel injection) in welshpool. Used them a few times. Can be a hit and miss though, i'v repaired a few 1jzgte ecu's. Most work fine afterwards, some have not. I think this is down to the boards being too badly damaged.

    It would be nice to have the circuit diagrams for these ECU's
    I am thinking there maybe a few caps which would be critical to the ECU operation, while the others are just power filtering, so it may not be necessary to replace all the cap ??
