Car idles at 2500 rpm...please help
 

I have a 1991 running MSPNP2. I've been tuning it by the advice of YT channels like CarPassionChannel and OGPedXing. I got it running on the base tune and got it driving like a champ but the idle was at 500 rpm. I tried to follow the instructions of those 2 channels with idle settings and changed it to closed loop and tried to set my duty % for the idle valve but now the car idles at 2500 and nothing I do changes it. I have set my duty valve to everything from 5 to 75 and it either stalls or goes to 2500. What am I supposed to do?
Before you ask, no I did not make a backup before messing with the idle. I was excited and confident since things were going so well I forgot to. Yeah I know I'm stupid.

I have attached my tune so you can look at it and maybe spot something I did wrong

Thanks

For some reason changing this setting to this ridiculous line made it idle right at 900 perfectly. I'm not keeping it that way, I'm positive whatever that is, it's not good.

uh, yeah, I thought that but tuner studio makes restore points for you if you can remember the date and approximate time you changed it and screwed it up. Look at the third line down in the file menu.

Can you take a log? There's a chance your TPS isn't under 2%, therefore never activating CL idle. I can't see your above picture, so I can't see what you've been changing to make it work, so i'm kind of taking a stab in the dark.
