Long story short... I pulled my ecu to send out and have tuned by enjuku. I found some bad corrosion on the connector and pins. And found pin 46 actually missing and just a rusted hole in its place. I had email communication with enjuku and told them I would definitely have no problem just buying a new ecu for piece of mind. The guy said “send it anyway.. it’s worth a shot?” I sent pics of the corrosion and pins...along with detailed emails. We had communication and he told me the tuner would look it over and let me know if there were any issues i was under the impression the situation was clear and I would hear something ...if they didn’t sell me another ecu.. the pin would be repaired. Or maybe it’s totally fine to be missing that pin?
But fast foward.. I receive an email that said” the tuner didn’t find anything wrong with the Ecu.. and tracking number. “
Nothing wrong? What about the corrosion and missing pin?
It seemed the ball was dropped.
Then I opened the package.. and the connector area was exactly the same. Corrosion and missing pin. On the inside of the board.. the pin still connects to the solder joint and looks oem. It’s on the outside it’s broken off.
Paid 400$ for the tune. Anyway, I now have a tuned ecu, with a missing pin 46. And no explanation response from enjuku. Still waiting. Thoughts? Thanks.
