Analyse Reliability
02.13
| 00:00 | - After each outing on track, the first thing to check is anything that relates to reliability. |
| 00:05 | This means not only the obvious things in the powertrain but also the reliability of the sensors we're using to measure our performance. |
| 00:14 | It's important to download each run individually. |
| 00:17 | This helps keep the data organised and makes it easier to review afterwards because it means you have a single log file for each change made to the car or driver. |
| 00:27 | Take some time to add some details to the log file to help with identifying it later. |
| 00:32 | Each logging system will have different input fields available at the time you download the logger. |
| 00:38 | At minimum you should include a sequential download number which might look like DL1, DL2, DL3 and onwards. |
| 00:46 | You should also add the session the data was recorded, driver name and anything else that'll help you when you're reviewing. |
| 00:53 | Like the setup change you tried on this run, the tyre choice, or if it was wet this session. |
| 00:59 | When checking for reliability between sessions, unless you find something that stands out, you don't typically need to go through the logged data. |
| 01:07 | Instead, you should make use of channel reports. |
| 01:09 | Most logging systems have some form of automatic highlighting built into the channel reports to show maximum and minimum values for each channel. |
| 01:18 | Which is helpful in allowing you to see any values that stand out. |
| 01:22 | For the powertrain, you should review all the relevant temperatures, pressures, voltages and currents to make sure everything looks to be in the nominal range. |
| 01:31 | Things like oil pressure and temperature, inlet temperatures, fuel pressure, wide open throttle lambda and battery voltage. |
| 01:39 | You'll want to do a similar review of the relevant readings for the performance related sensors. |
| 01:44 | This is more to catch a sensor that has started to fail or needs attention so it can be rectified as soon as possible. |
| 01:51 | Skipping this step, can lead to making some of your data unusable should it now be caught as early as possible. |
| 01:59 | Some examples of the sorts of things to check are steering position being zeroed, minimum and maximum brake temperatures, wheel speeds and brake pressures should all be scrutinised carefully. |
