Thread: 1jz ecu capacitor repair service

  1. #1

    Default 1jz ecu capacitor repair service

    I just fixed 4 ecu's this week alone, with caps leaking on the pc board, and since the electrolyte is acidic, it ate through the traces on some of the boards causing major problems. I am going to start offering a repair service for them, it's really becomming a big problem for a lot of people. It does seem to be random, the car runs fine, then just starts running like crap one day. One I repaired just would not start. One would run super rich and bog down. On one, the idle was surging from 700 to about 2k, even with the ISC disconnected! On Jay's car when we first started it and the dp was not tightened yet, it was running so rich that gas was literally pouring out of the turbo!!! On Charles' 1jz it smoked badly with thick whitish smoke. If you have not replaced the caps on your ecu, do it now, they are ALL going to fail at some point.

    It will be $70, including expedited 2-3 day USPS Priority return shipping.

    If the car doesn't run at all it's possible that the problem is more then just capacitors, so I can't guarantee the replacing the capicitors will fix the problem. It is also possible to have a bad wiring harness or some other issue that makes the car run poorly, but replacing the capacitors is a good idea either way.

    Please include all your contact and return shipping information on a piece of paper inside the box!

    I can test it, but it might delay shipping back to you by a day or two.

    Like Rakkasan says, if you are that iffy about it, maybe it's not a good idea to do it.

    Awesome new service, Aaron! Do 7M ECU's sometimes do this?

    There is, unseen by most, a side of the Supra that is just as real, but not as brightly lit. A Dark Side.

    Not that I have ever seen myself, but it is possible that the capacitors could fail at some point I guess. I wouldn't worry about it too much, but you could pull the cover off and take a look at the caps. If you see black goo or a dark discoloration on the pc board under any of the capacitors, then there is a problem:
