I had soccer games plus a friend that needed a muffler welded back on, so I didn’t get much done this weekend. So much for my ambitions to start the car by Sunday.
I decided to use the GM sensor that was part of the original MegaSquirt setup for the IAT and the DOHC CLT sensor. Using TunerStudio, I set the calibration from the drop down boxes for those sensors and they seem to be sending rational values. The O2 sensor is a real PITA, though. I’m not convinced that it is truly linear and the voltage at 14.8 with the sensor unplugged (per the manual’s suggestion) is different than the voltage at 14.8 with the sensor connected. I re-ran the ground wire for the O2 to the same p,ace as the MS grounds, though, and it seems to be closer on the lean side of the scale at least. I also ran a ground wire for the ignition box so that I can hook that up.
Some grinding on the front bracket for the torque strut gave me the clearance I needed to get the hot side pipe run and I got the wiring from the alternator to the starter routed. I utilized a good number of insulated clamps to secure the wiring around the front and passenger side of the engine and bought some more split loom to protect the wires and some hose clamps to complete the heater core connections.
The list:
- PS belt
- Run wires across front and right side of engine (50% complete)
- Put hose clamps on water hoses to hardline and heater core
- Install radiator
- Install cooling fans
- Re-install MegaSquirt
- Install PCV system
- Add hose barb to air cleaner pipe for valve cover breather
- Install cold-side pipe
- Torque down O2 sensor
- Install oil filter sandwich adapter
- Install oil filter
- Fill engine with oil and turn by hand a few times
- Install axles
- Fill transaxle
- Try to start engine
- Re-install front end
