i think you can but not for long tho they will still shut off. leaving them on longer will result in throttle hang why do you need em on?

All you need to do for decel popcorn is to apply a little throttle. Just use the big toe.

With late enough spark you'll make new friends (hells angles type)

The injectors do stay open during decel after WOT. This is the factory behavior.

and how to stay open it for longer time ? :$
Do we know what is the differences between the 4 table ?
- Decel Fuel Cut Delay 1
- Decel Fuel Cut Delay 2
- Decel Fuel Cut Delay 3
- Decel Fuel Cut Delay 4

and what are the numbers in the table mean ? different load how long stay the injectors open on decel ?

What does Decel Fuel Cut Retard doing ?

I have 2 things, on cruesing after let of the pedal first the car goes so rich ~10.5 than how it shoud going to lean and cut of fuel. After wot I didnt see the same things. Maybe it is the idle control valve problem dont know.
But after Wot I would give fuel for the car because ALS Dont know maybe the mr fred patch the closed loop control by wbo2 could help on it ?

Even easier to throw a block of -1's in the high rpm, low load area of the map if all you want is pops and bangs at lift off??
