mabe some decel fuel cut logic is killing idle?
the lean-out above 4500 rpm is like fuel pump can't keep up.
Wonder what a/f was for the stock spg?
Unfortunately, few really know how the LH works. LH is batch fire, runs off amm initially, then near top end switches to something else. with boost steady, inj pulse should be near constant as rpms go up after torque peak. be real interesting to check inj duty cycle and fuel supply pressure during a hard pull.
The apexi signal conditoner (that dr xx picked up on from our early discussions here ... split-sec ARM1, etc) would work with the rrfpr run, where u ended up near 13:1. Unit has 2 tweak maps, for hi and low load ranges, lower end could be leaned out.
HKS version actually has an idle control too.
