MSP
Off to Minneapolis I go. On Wednesday the low is 8, and that is below the threshold of reasonable.
GTR
The GTR is back in the house. I picked it up from English Racing today so I can put some break in miles on it. Thanks to Myles Kerr, Sean Hart, Brad Ruth, Atif Awan, Lucas English, and the rest of the guys at English Racing for the incredible work.
As soon as I get the break in done, Timothy Bailey and I will get it on the dyno.
Oh and here is a list of what they did for me:

And the car already had (and still on the car):
Jacks Drag950 Transmission (18-plate clutch, billet 1-6 gears)
Cobb Midpipe
Legamax Exhaust
Gotboost Flex Fuel
CAN
I did a little testing to verify the capture and CAN transmit times on this 40MHz dsPIC. Time for capturing all 8 analog channels is about 58us, and time for transmitting that data over a 1mbit CAN bus is about 130us.
I had no problem setting that capture and transmission rate to 1000hz (1ms), since I am under 20% interrupt time load.
For most uses cases I will be capturing at 1000hz, but using an FIR filter to decimate down to 100hz (or less), and then output over CAN at 100hz. It is pretty easy to make multiple FIR filters for different decimation rates per channel.
When I switch over to the QFP44 version of this controller I will certainly be able to capture all 13 analog inputs and send them over CAN.
Not bad for a microcontroller that is $3.
