Pistons and rods installed. Just waiting on a set of STDX King rod bearings to make some adjustments to my big end bearing clearances…. Unsurprisingly, the STD size bearings EPR used produced 0.0017” clearance not the 0.0035” quoted in the build sheet. Targetting 0.0025” for this build. Also reinstalled the @brettdempseyengineering oil tree. Oh and I will never use a ratchet piston ring compressor ever again, these ring compression sleeves are SOOOOO much easier to use!!

emissions is 6% on CO level. very rich.
the MAF reading is 1.3 (ok i beleive)
timing 15 deg (fine)
injector pulse 2.27ms
injector duty 2.11%
IACV 17%
the TPS was out, it was 0.80v, now corrected to 0.48v
i need to lower the base idle i believe, as its 1125rpm.
now then, the o2 sensors.
Left 0.65v (on idle)
Right 0.34v (on idle)
when reved the car to 2000rpm, the reading just stayed there, maybe increased/decreased a little, but its supost to go nuts isnt it?
when i lower the base idle, will that lower the voltage, decreasing the CO level? or are the o2 sensors broke?
