The instrument panel is a 12.1" touch screen. It's big and bulky because it's a 2000nits bright display intended for ships and is direct sunlight viewable. Behind the dash is a little minibox PC that runs custom software and interfaces to a SnEEC datalogger (a product I designed/sold for the EEC-IV Mustang for many years).
Right now, since I'm shaking down the car, the panel displays the kitchen sink. Can I read it all, hell no. However, I don't really need to. If something important goes wrong, the PC will flash the entire background of the dash either yellow or red depending on severity; and has the ability to do things like rev limit the engine, switch to an alternate (less aggressive) calibration, and so forth...if needed.
After this track experience, I can tell you that the only thing I'll have on the dash for "track mode" is RPM, MPH, and warning lights. I don't have time to look at anything else. In fact, I'm going to install a very loud sounder under the dash because I'm not sure I'd even see a flashing yellow/red background...my eyes are very much on the road.
Thanks for your compliments, I was really pleased with how it all worked...this was the first time I ever exercised the car at this level. I'm going to buy one of those gomotorsports cameras for an event in June...hopefully next time we'll have some decent audio.
