I've got several Jetcats, and normally if you replace an ECU (V10) it will reload the data from the engine, including total time etc. On one of mine, I have swapped the ECU, and on startup it goes through the usual routine of reloading log data etc, however the engine total time counter is at zero. Have tried a couple of different ECU's with the same result. The engine time is recorded by the ECU but also saved to the engine, and normally it comes up again just fine after an ECU swap. Anyone seen this before? Any ideas?

Cheers,
Colin
