mine ah i shift at around 6
after tat can feel like da car starts to losin power liau wan ..
hehehe .. i think all stock ecu cars should have rev cut gua .. tahts why i was shocked when i heard ur stock car no revcut.. anyway i pasang my A-FPR today also .. pick up much more better after stepping down my stock pressure which is 42psi to 36 psi. anyway what is FMS?
FMU - fuel management unit, also called RR-FPR (rising rate FPR), to boost the rising of the manifold pressure at a factor. Stock FPR and most of the normal A-FPR is 1:1 rated. Meaning 1 psi increase in manifold increases 1 psi in the fuel rail. FMU or RR-FPR is 1:1.xx rated. meaning it increases the fuel pressure at > 1x than each psi increase in the manifold pressure.
See the diagram in the bottom of the post.
mine is a denso unit from japan. Used, quite old, non-adjstable but still gives a boost.
yes, i lowered the idling pressure to 32psi (stock 36psi).
The combination seems to behave pretty well.
rev cut.. really lar.. last time tested in LDP in first gear. Dragged to 7.2k and still going wor..
haiyah.. why cannot liao arr? maybe last time was a fault in the ECU?
