I noticed when I'm cruising and I let off the gas in gear to decelerate it doesn't cut off the fuel(fuel cut)

Yes, I tried messing with the fuel cut but don't know what I'm really doing.
Tried creating a baseman and not touch anything still doesn't fuel cut.

If anyone had this prob before and fixed it let me know how did you do it what setting did you set it at thanks

 

I believe we've already spoken and I told you that you're not crossing the thresholds. There's three settings you need to make sure you meet.

TPS
MAP
RPM

You can take a datalog and review to see where these are during decel, then set your settings accordingly.

 

My setting is at minimum rpm 1200
Below tps 2%
And load is 213

I got the rpm and tps down for sure not sure about the map
Map=load?

 

Nvm thanks got it to work. Stock setting on the load was too low.
Stock= 213
Was data logging and saw that idle was around 350-400 so I set load at 500 and works like a charm thanks

 

You'd want to set it just above the load you're hitting during decel, not idle. Also the RPM setting is a minimum RPM for the cut, so you may find 1200 is too low to recover in certain scenarios.

 

What should I set it to? Any suggestion? Like 2000 rpm?

 

1900 is default.

 

I also have trouble setting up my fuel cut. While I'm in decel the car feels fine for a bit, then starts to buck. I haven't been able to figure the problem out.

 

depends on your driving style and application. on my personal cars I set it to 2200 in case I get caught in bad traffic, so I don't have to battle with that jerky part-throttle when I'm creeping along at 5mph.
If you have an aftermarket throttle body (especially skunk2), you may need to set it higher than 1900. Some injectors may cause idle recovery issues also, namely Smartfire if you're into making bad decisions, but also RDX and Precision 1k's.

 

you have some fuel cells that aren't properly tuned. when it's recovering the vacuum shifts right a few cells, and it's difficult to dial those cells in properly.
drive in a high gear at low speed and get a ton of logging in all of the first 4 rows. roll the throttle in and out slowly to eliminate tip-in and O2 lag.
