Hello this issue started happening recently as my tps was really wonky so I swapped it out for a bmw OEM and that fixed my throttle issue but on the other hand my idle remained the same and it starts but dies or start and has a hard trouble catching at 600-800rpm but before this would never happen so im not sure if my settings now that my tps is good is correct or if I messed up on something I attached my tune and some logs of me driving(trying to keep the car running at low rpm) in my tune for engine state I have my accel and decel at 20k to see if that was the issue but it was not I'm really stuck and not sure what I am doing wrong. hopefully i dont sound dumb and its a simple issue if I need to provide anything else I will im just really stuck.

You're idling around 44% idle duty, but your initial duty table is only about 29. Your tune needs a lot of work, but try the attached, it's a huge amount of changes, compare them to your current tune to see what I did, highlights are turning off VSS since you don't have one programmed, turning off idle VE, turning off idle advance, setting up idle ignition correction, turning on EGO, evening out your idle target, and increasing your max duty.

I think one of the bigger issues you have is not enough throttle bypass. Start and idle the car with this map loaded, wait for coolant temp to level out, looks like around 185 for your car, then rotate the idle screw counter-clockwise 180* at a time, while looking at idle PW, until it's around 35%. Give each changes a few seconds so CL idle can get back to target. Once you do this, your idle will probably hang high before dropping down. If it does, select the entire initial duty table and subtract 5% at a time until it reliably returns to a stable idle.

P.S. I've never seen your car, so this is all assuming you don't have some other mechanical issue going on.

Hey yeah so i fixed the initial duty table and put it higher and that fixed my issue Ima take your log and try it tomorrow(today technically) the only thing now is coming to a stop it drops to around 500-600 then catches back up also the startup itself is not like the typical crank where it goes to lets say 1200 rpm it just starts up at 500 and makes it way to around 900 not sure if that's my cranking rpm or crank duty also the idle screw is as closed as it could be.
