Track Day Seven: Homestead 09.12.15 with PDG

New Stuff:

ELECTRICAL
Happy to report that all my surgery on the wiring harness worked out. No electrical problem and everything works as it should, including traction control, AC and electric windows. Even the remote key fob and trunk release work. Good news

The interior plastics are also back on, the glovebox even has a functional cigar lighter plug !

BRAKES

New front brakes carbotech xp12 installed. First session was scary because the brakes were giving me a shaky feeling on the steering, I wanted to bed the pads really carefully, considering the reason for the switch was that my previous set of CL 6E did not perform well and left uneven wear on the rotors, an dI wondered if it was because I tried to bed them in too fast with hard stop and go (like it says on the box. Based on @CSG garage advices, I decided retire the CL 6E for now and match the front pads with the rear pads (XP12).
After a few laps crying over my shaky steering, mid-session I decided to press harder on the brakes. After a few harder stops, 10 times at 50% pressure, the shaky feedback stopped. I went on a little more then I went for a few cooling laps. Next session the XP12 started were very noisy with a heavy/scary rubbing noise but after a few minute in my second session it felt smooth. The rest of the day was fine too. Still I think I need to learn more on the bedding thingy...

XP12 definlty provide tons of power, more than what my stomach can take after lunch

The ABS still kicks in during transition braking from turn to turn, so may be the rear differential is causing the ABS to kick in.

HVAC
The AC is back on the car and the addition of the AC condenser did not seem to have any impact on cooling. The AC is great on the grid and to get ready, but on the track, I still need to add a coolsuit, it was super hot and I was sweating like a pig all day.

I missed greatly my NACA duct that was located instead of my triangle window, that stuff worked great on the track. I need to figure how to retrofit one on my new setup. I see many miata replace the triangular windows with lexan and a NACA duct, I'll work on that later.

WINDOWS
I added back the side windows and electric mirror are now functional as well. The location of the window buttons, inside the door, where the speakers were, is ok but not ideal. Once strapped in the car on the grid, enjoying AC. I have to loosen my top belt to be able to open the door slightly and press the buttons. I can quickly tighten my belt back on fairly quickly so I think I am ok for now, but would be nice to have the window buttons accessible once strapped in. Center console somewhere. May be if I look hard enough to the wiring schematics I can find a wire to use to bring both windows up and down.

WEIGHT
The car is certainly 300 lbs heavier now with the full door and the AC. It felt a little heavier but nothing dramatic.

Other stuff:

COOLING
oil coolant and temperature where stable. Harrys lap time latest update did bring up the oil temprature via my bluetooth OBDII (GoPoiunt Bt1). I was waiting for it for a long time, it seems the new updates did it.

TIRES
The car performed flawlessly all day, only had a flat tire mid day, luckily I switch from me 245 BFG R1 to my 225 ADV08 and I could barely see the difference. Actually I made the same times I think. Certainly because I did not take 100% on the faster turns 1 and 10. I wanted the session to be about testing the car, so I kept it easy. Best time of the day 1.51 on the road course.

HOOD PINS (lack of)
My hood popped open, I certainly did not close it properly before leaving, the safety mechanism kept it close, but that reminds me that I need to add manual 'aviation hood pins'. Would have sucked to crack my windshield and damaeg the hood. It popped open around 65mph or so. I pitted in to close it and did not re-occur later.

GAS FILLUP
I manage to fill my gas tank with the fuel jugs without a spill, first time... For me the trick is to watch the transparent hose and look at the flow while not lifting the jug too fast. it seems once the flow is maxed out, if you tilt the jug more, then the air vent get 'clogged' and it back flows. Make sure you see the bubles flow from the jug to the car and not the other way around

HARRY'S LAP TIMER
I used harrys lap timer, with my vbox sport and got great data but video overlay with the gopro sucks and could not do it right. I wanted to use the gopro as main camera, but the file size are huge and it is a mess to figure which video correspond to which lap.

I tried the software RaceRender for the first time and it is a really nice system, mac compatible , to create overlay video. But still the problem of finding which data correspond to which video is impossible to solve. See below, after an hour trying I gave up and overlaid some data over the video but they evidently do not match.

I need to get myself a smartycam and an Aim MXL to collect more data.

REAR VIEW MIRROR
I removed my long acre rear view mirror and now back using the stock rear view mirror, it is much better. the longacre was too distorting and I kept on missing people behind me. I need to sell that thing.

SUSPENSIONS
I need higher ride height and also more compression. on turn 10 I bottomed out a couple of time, when I gave too much steering input, with smoother steeering transition it did not bottom out. Anyways at this time the ride is very comfy, I can make it a lto stiffer. I think I have 7 from full compression right now, need ot double check.

POWER
I am still full stock, except OFT flash for 93 octone. I pass NA miata easily in the straigh but a track e36 was faster in the straight (see video).

DRIVER BELTS
I need to modify the right driver lap seat belt anchor as the motion is a bit limited, twisting the mounting point would help or add a ring to it or something.

PEDAL DANCE
I almost forgot twice to do it, and once I forgot completly, and had to pit in to do it... really annoying.I thing the beatronic tool is in my future.

I think that's about it

The car is ready to roll for the next event, nothing needed. Only potential improvemetn with NACA duct, cool suit, and smarty cam.
