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?

Likely choice:

Others:

  • Mueller MotorWerks EVO2: Lithium, 3 lb, 28 Ah, 550CCA, 269$ -- Looks like potentially a really good option. How is it so cheap for so effective a LiIon battery? Something has to be fishy. Try to read up more on it...
  • GRRReen 20Ah: Lithium, 7.25 lb, 20Ah, 330CCA, 289$

Ridiculously expensive but awesome:

NASIOC Battery Post with a bunch of other misc batteries.

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. ST and SP both allow free relocation of the battery.

There's a rumor that the Deka ETX9 is the same battery as the Braille B106 (that the Braille is a rebadged Deka). The cranking specs are quite a bit different, but the ETX9 is ~55$ and the weight is the same. Some people on Miata.net have run them successfully, but I'm skeptical. Maybe start with the B106 and if it dies too quickly just get Dekas to replace them?

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.

Traction Control

Race Logic's stuff looks pretty awesome. It'd plug right in with our existing ABS stuff, be nearly plug and play using Kyle's patch harness, and costs ~900$. The unit we want is the RLTC6AL (ABS + launch control). Trying to figure out who to buy it from...

  • Woodhouse Motorsports: Has it in stock, 1295$ (phew)
  • PDM Motorsports: Emailed Don Nimi to ask

Need to contact some british sellers to see if they'll mail it over the pond.

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...

Wiring Harnesses

Body Harness

We can remove the airbag and radio circuits in entirety. We can remove the power windows and hard top heater wiring because it wasn't present on the '90. Remember to tear out the antenna cable from the PPF line.

Engine Harness

  • Tear out the AFM wiring while the harness is apart
  • Figure out where the battery cable enters the main harness
  • Learn what all the various relays against the walls do and if any can be eliminated
