So technically the bumper posted above would be illegal. . .

Illegal modification via curb or car . . . .

I'm glad my car's not the only one squealing into grid

Do you left foot brake? Seems like there were some times where both the gas and brake were signaled.

What video hardware and software are you using? I love the overlay! Is that the ChaseCam stuff? I just picked up a Motorsports Pro Wide setup and am going to try to get much more video of my driving and the car this year. . .

How did that run compare with the top times of the day? Seemed like a fairly slow overall speed course. Didn't even top out in 2nd gear. You think there was another half second or so out there maybe?

What pads are you guys using. I'm thinking about changing to something different than I've ran the past 4 years. PM me if you have any good recommendations or warnings. Thanks!

Hey - i just had a thought.

When you guys use trail braking, do you brake with your left foot or do you just right foot brake ??

yeah we've got a chase cam PDR1000 and we just started using dashware for the video overlay. Dashware is some seriously awesome software. Very powerful. It's cheaper then trackvision to boot. My friend and I created all those gauges from scratch, I should probably put a label on the "oversteer/understeer" gauge that's on the left side of the screen.

That was my fastest clean run from sunday. It's not really anything too special. The course punished the slightest amount of over aggressiveness so the video came out looking kinda boring. Time wise it was 1.5 secs (raw) behind the fastest paxing (CSP...again) car at the event. .8 behind Tom's fastest (first and only dry) run.

Brake pads: we just put on a set of HP+ (they were free). Initial impression is that they're a little more linear in the higher pedal pressure ranges and noisy once they're hot compared to stock. no measurable performance difference, they just feel different in the pedal. I haven't used any other pads on the race car so really my opinion isn't worth much.

How does that work? Is it based on wheel speed sensors or is it all accelerometer based? Multiple accelerometers? Tell us more.

accelerometers, gps speed and a yaw rate sensor. up/green is oversteer, down/red is understeer. not corrected for road slope.

basically it's calculating the neutral steer yaw rate for a given speed and lateral acceleration and comparing that to the measured yaw rate.

Nice job on P1, Marshall

What kind of power is that thing putting down--seems really strong

OK, yaw sensor, that makes sense.
What have you learned from it, anything?
It seems a little inconsistent, maybe it works a little better on a flatter surface/venue. I have heard (and seen in pics) that Qualcomm really has a lot of elevation changes, maybe that skews the results a little.
I tried to just watch your steering inputs and the over/under guage, and it seems if anything that the car has a little bit of turn-in understeer. I have heard that the TRE diff causes so much throttle over steer that you have to re-setup the car for a little understeer is that what Iam seeing there? Give up a little turn in to gain in the exit?
Oh yeah, quit being so vague about things (your setup). lol

On a side note, in regards to goofygrin seeing brake and throttle inputs at the same time, isnt that impossible? Its based on G's not throttle/brake sensors right? Maybe the system cant keep up with the quick transitions?
