Brand-new Microsquirt package, purchased from DIYAutotune, never got around to it. I'm in the process of downsizing and would love to see this to a GRMer.
Microsquirt with 8’ harness
QuadSpark ignition module
GM 3 bar MAP with uncrimped connector
GM Open Element IAT with uncrimped connector
CLT/IAT sensor with uncrimped connector
Mild steel Wideband bung with plug
Aluminum 3/8 NPT bung with galvanized steel plug
$650 to purchase new from DIYAutotune; $325 shipped in the US
Add a wideband sensor of your choice, plus a little wiring and tuning, and drive off into the sunset, or Challenge glory!
