I just installed the kit off ecmtuning for speed density. I set everything up but for some reason the car won't idle. The car will idle great with the vacuum line off on the MAP sensor. Once plugged in, It won't idle at all. I'll post a log of me trying to start it so u can see my settings. I couldn't get the car to idle good from my hacked MAS either. Had to raise the 50hz slider almost all the way up.

I just went out and messed with the VE table and upped the values to get the car to idle. It idles lopey and seems to idle a little on the lean side but atleast it stays running. For some reason, the ISC position is at 100 even when I mess with the BISS screw. The combined fuel trim was around 14 percent but I messed with the dead time to get it to around -4 and 0 depending on the idle. The airflowperrev is a little high too and being speed density, i'm not sure how to go about doing that. Is it even at all possible to use the combinedft adjust from a previous log from when I had my MAS installed?

All the people running SD, no one has any suggestions? I'm about to give up on this car and ecmlink.
