Hi guys, I'm wondering what tables are defined for Decel fuel settings.

I'm running Tephramod 96530706 and I have so far:
- Decel Fuel Cut Delay 1
- Decel Fuel Cut Delay 2
- Decel Fuel Cut Delay 3
- Decel Fuel Cut Delay 4
- Decel Fuel Cut Retard

I can hear pops and crackles when I lift off the accelerator, and the throttle response getting on the accelerator again after backing off can sometimes be quite sluggish.

What settings do I need to modify to fix this? I'm guessing reduce Decel Fuel Cut Delay? How much to reduce?

Also what is the difference between Decel Fuel Cut 1, 2, 3 and 4?

 

i would like to know more about decel fuel cut delay tables too...

 

nobody has the answer? seems like this is an important part of the rom on drivability.

 

iirc these tables are responsible only for closing the injectors when you lift off the throttle. they aren't in play when you push the accelerator again
after the throttle lift-off they control the time delay when to close injectors completely

 

You have other issues that dont really have anything to do with these tables in particular. What mods do you have, has anything changed recently before it started driving like this?

I was thinking this was the purpose of these tables but when I posted something about this in another thread, one of the "professional" tuners on this forum ripped me and told that's not what they were used for. I'd love to know the answer as to what these tables are really used for if the above description is incorrect.

 

I believe these tables were found to named incorrectly in another thread. I believe these turned out to be ISCV DEMAND TPS Adder tables.

Actually heres the thread

Thanks I'll look into that thread a little more when I get time. I did find that adjusting the Decel Tables (even tough they're labeled incorrectly) did help some with the clutch-in-idle-stumble-problem.

 

me too, would like to know how to interpret this 5 tables
