Battery

Currently a stockish battery (?). What are good options here? Odyssey makes several options, but there has to be better nowadays.

What does the current battery weigh?

• Braille B106: AGM, 6.9 lb, 10 Amp/Hr, 210 CCA, 527 PCA, http://www.amazon.com/Braille-Battery-B106-Lightweight-Racing/dp/B004DDI12O 140$+FS]
• Braille B106C: AGM/CF, 6.9 lb, 10 Amp/Hr, 527 PCA, 225$ -- Any reason to go with this instead of the 106? Does the carbon fiber case do anything useful? It's the same weight...
• B106 Mount: Aluminum, 55$+FS
• GRRReen 20Ah: Lithium, 7.25 lb, 20Ah, 330CCA, 289$

Ridiculous but awesome:

• Braille ML9C: Li-Ion, 3.7 lb, 36 Amp/Hr, 612 PCA, 950$
• Braille ML14C: Li-Ion, 4.5 lb, 42 Amp/Hr, 773 PCA / 548 CA, 1250$

Need to buy a trickle charger too.

Does it make sense to weigh the battery cable that runs along the PPF? With a tiny lightweight battery like this, it might make more weight sense to put the battery up nearer/in the engine bay and drop the 10 feet of thick copper cable.

Engine Management

Bought a MegasquirtPnP. It only supports batch fire injection and wasted spark ignition, but that should be fine for us for a while or possibly forever. I'll eventually need to buy a KnockSenseMS board for knock control with it, but that can wait until I get the supercharger started.

Wideband

Bought a Zeitronix Zt-3, the same thing I've been using with pretty good success on the KLiata. The MS3 seems to support it just fine.

DAQ/Instrument Panel

Buying an Evo4 + MyChron3 for now. It can read from the MegasquirtPnP (MS1) via RS232. It supports as much data as we want down the road -- can do 12 tire temp inputs, 4 shock pots @ 1000Hz, and our other analog pressure/temperature inputs.

Tire Temps

Opti-Grip seems like a surprisingly affordable package. Would need to figure out how to integrate it into existing datalogging, but it could be neat...
