EFIDynoTuning Forum

Hello everyone I am have a issue with my truck. I can't figure out why it's loping at idle and some times when I come to a stop.

I have changed the idle control settings and IAC duty cycle back to stock with no change. The truck has a brand new motor craft IAC valve.

The truck is turbocharged and tuned with SCT.

PLEASE HELP !!!!

Idle airflow tables. Have you dialed them in if it has them?

Where are the tables located in SCT and how do I know what to change them too.
Side note I am not new to tuning BUT I still have a lot to learn so if I say something stupid my bad.
I am still trying to figure out what everything is and dose, there is a lot of info on this forum.

make sure you have idle transient fuel disabled

under transient fuel >> scalars set No TFC at idle to 1

btw, KHM3 is an ODAJ0 / MPC-201 ecu. http://www.obdtester.com/ford-ecu-updat ... -12A650-KD
Your in the FBGI0 section. All good though.

I don't see my section or strategy. Where should I be posting in.

Good question. I expected the pcm tuning section but I had specifically wrote in there non ford back in the day. Corrected and moved.

all good

Where in my tune can I adjust the idle down table so it is smoother when the truck idles down from a rev.
it is jumpy when the truck idles down.
also I made a small idle adjustment at the throttle blade and the truck would not restart until I put it back in the same spot, what is going on with that.
I am using SCT software .

That's dashpot, info is on the homepage.

Sounds like you have some issues going on as that's not feasible.

Could the TPS have a bad spot in it, I don't think it is a motorcraft TPS.
but it didn't do it before I uploaded the last tune you sent me.

even with the tps unplugged it would still start up

only possibility is that youve closed it too far and it cant get enough air
