This is confirmed to be fixed in released firmwares 1.1.95 and 1.1.96, and even in 1.1.94) but it wasn't reproduced on bench and hard to tell exactly what fixed it.
* anyone knows when exactly the problem disappeared ? 1.1.93 ? or 1.1.94 ? * anyway, it is a good test-vector for the automatic tester ---- |
| A rare problem with simple trigger causing mysterious stumbling has been noticed by several people, myself including. This time I found a car where this was easily reproducible. |

| Immediately we noticed how the engine started to stumble at an exact rpm, not only that, we could see the tachometer drop a little as this happened, and because the tachometer took it's signal directly from the negative on the ignition we could figure out that there was simply no spark fired at that moment. A slight lean reading from the lambda was also a clear sign. Importantly the car ran fine up to this point with 1.0.73, just minutes before. |
