Also, ball park napkin calcs tells me that TEMIN during cutoff is still quite a bit of fuel.
I am skeptical that the injectors are still firing..
I also don't believe that fuel is dumped when off the gas pedal.
As phil said, fuel cutoff is done after ti got computed:
Fuel cutoff is applied after the calculation of ti_b1(2).
It is applied to ti_ev0...7 in ACIFI.
So you can still log ti > 0, but the injector is not opened in reality.
The injection driver code finally decides which cylinder really gets
injection and which one not.
The bitmask evz_austot is used to disable injection on cylinder basis.
If a bit is set to 1 in this bitmask, the coresponding cylinder doesn't get fuel.
You can log the following two variables in M-Box to see wether injection takes place or not:
redist , {Inj-Reduction} , 0x380B92, 1, 0x0000, {#} , 0, 0, 1, 0, {Ist-Reduzierstufe}
evz_austot , {Inj-Cut-Mask} , 0x380B90, 1, 0x0000, {-} , 0, 0, 1, 0, {Einspritzausblendmuster total}
'redist' is just the number of 1-bits in evz_austot, so this is the current reduction step which
should read 6 if all cylinders see a fuel cut and 0 for normal operation.
'evz_austot' shows which cylinders are cut. Unfortunately you will have to convert this value in logfiles
by yourself from decimal to a hex value or a binary value to see which bits are set/cleared therein.
