...the shop manual says,,"during decel, with the throttle closed (TPS =0.50v) the injectors are shut off....B16A2 970rpm (that 120 rpm above the "standard idle of 850 rpm
I hope very much Hondata can consider implemented TWO
explicit user defined fuel cut-off parameters in increase the "joy"....
a) De-cel Fuel Cut Recovery (no air-con)
b) De-cel fuel Cut Recovery (with air-con)
Is there a way to explicitly control this - need for huge primary lobe race cams (not jun 3) used as daily driver...you can control the throttle breakpoint and timing but you cant seem to touch the rpm when the injector switch back on (it seems to be hard coded at 970 rpm (which is fine is your idle is 840rpm,,,,,....please share/comment....
....really appreciate it as i can imagine the (effort of hacking code and figuring out the subroutines, links etc...all in binary)

The fuel overrun resume rpm is dependent on coolant temperature and vehicle speed. It is about 1050 rpm when hot and stationary and 1350 rpm when hot and moving.

Useful Info for a tuner - I will set my idle around these RPM
Can it be put as a note in the software under TPS or Idle ? I hope Hondata can exposed these fuel recovery RPM breakpoints to the tuner in future releases ( i know that that would be lot of effort) :idea:[/b]

Got me thinking ....How do the following "sub-routines" in ECU interwork
Idle (stationary & moving)
Warm-up...
Fuel Cut..
Decel Fuel Recovery (TPS & Map)
Tuneable Fuel Cut Recovery RPM

Does hondata plan to implement a
user-adjustable rpm where the injectors are
switched back on, in the "return to idle" zone (orange zone above) :D
