ok so I am new to using dsmlink and I am having a hard time getting my idle tuned. I am running speed density and I cant seem to get anything to be where it should. I am also having trouble getting my estimated afr to match my wide band they are way off from eachother. I appericate any hel anyone can give.

There is a lot wrong with your log (sorry...I know you don't want to hear that LOL.

Your airflow isn't calibrated, you are using the sliders, TPS isn't adjusted, etc.

I HIGHLY suggest you read through this checklist over on our new ECMLink tuning forum, and watch the videos that are mentioned in #12.

It also wouldn't hurt to read through the other stickies at the top of that forum as well.
 
Haha that's what I figured.this was installed and running ok on the 7bolt before I did the swap and now it's not even close.i will take a look and guess start from scratch.i would of thought I would still be in the ballpark but I guess not.

ok I went back and adjusted by idlesw to read 1 at no throttle and my throttle pos to read 0.The car still wants to idle high at like 1200rpms even though I have it set for 900. What do you mean I'm using the sliders?global and deadtime for my injectors are set to the correct starting values. Should my timing be that high at idle?I would think it should be lower.
 
ok so I have now got my fuel trims and airflow to where they should be. My problem now is my estimated air/fuel in link is reading around 14.7 which is perfect but my wide band gauge is reading in the 16s.What could be the cause of this?
