We routinely get asked about turn around time for various ECU services we offer. So I'm putting this page up for future reference.
First, understand the process of getting an ECU worked on by us. The steps are listed below.
So when someone asks “what's the turn around time”, I'm never sure how to respond. The only parts of the process that we actually have any control over are steps 3, 5 and 6. I'll cover each of those below.
UPS always comes in the morning around 10 AM to drop stuff off. They return around 4 PM to pick stuff up. When we get ECUs that early in the day, it's almost certain we'll get the ECU tested that same morning. And often, if the ECU is a simple socket/caps or simple repair we can even have the ECU back out for UPS pick up that same day.
Anything other than UPS is a crap shoot. Sometimes they show up early, but usually they don't get here until late in the afternoon. At that point, it's almost impossible to get any real testing/evaluation/work done on it same day. Expect to hear back the day after we get it if not later that same day.
It's rare for us to be backed up more than a few hours at a time on ECU work. If ECU work is going to take more than a day to complete, we'll usually let you know. It's *really* rare for us to take more than two days to get an ECU done up and ready to go. The exception are cases where the customer has specifically requested an in-car test or the situation/problem description deems that level of testing necessary. In those cases, it could take an extra day or two before we have time to get the ECU reconfigured for our shop car, get it installed and then drive around and reconfigure it back.
So the short answer is…there's no short answer. The time we spend actually working on or testing an ECU would rarely be more than one day. So by far, most of your “turn around” time is going to be in shipping and in the possible e-mail communication back and forth and/or payment time. And how long that other stuff takes is completely out of our control and can vary from a couple days to (in some extreme cases) several weeks!
