Great day and fine weather. Oulton goes back up to the number one slot as my fave track in the UK. Lots of cars on circuit so not many clear runs and a huge trail of oil on track (a caterham split his sump) from foulstons to the pitlane just before lunch but hugely enjoyable all round.
Really need to get the car flat floored, it keeps locking up all the time and I suspect the corner weights as the videos show including an excursion to the gravel trap. When I removed the damper spacers before Cadwell I just guessed at the ride height and spring platform positions. Calipers seem to be working both sides so corner weight is most likley suspect.
Made some decent progress at oulton after a terrible visit last year. There's still a lot left in the car generally especially in the faster bends and hopefully ill get the locking up and wheel wobble sorted shortly and will be able to use the brakes in anger.
Datalogging was working (mostly) well and using overlap software created by Matt Daniels I have created some data overlays on my movies showing speed, G force and revs on some custom dials I made.
However i've discovered that my speed sensor reading is out for some reason and always several mph off a true GPS reading. I've triple checked the tyre circumference values so something must be amiss with the sensor or its mounting. I have adjusted for this error using a multiplier in the datalogging software for 4th gear so high speed is pretty accurate but it means that lower speed 3rd gear values are slightly too low. Still, its there or thereabouts. Thinking about getting an in-car GPS speed reading gizmo like the one race technology do and just plug that straight into the Mychron.
Mr Daniels reworked Overlap to work with some custom dials that I made so here are a few videos with datalogging superimposed. Plan to have a throttle meter, shift lights and oil/water temp readings at some point as well.
