So, I just put in Crower stage 1 cam and now I have a horrible idel. I know it will idle different but what should I be looking at when I'm data loging? When my car is at stop light/sign it will fall on it's face and all most die. I have had this problem since I put in the cams. I am perfect at TDC so I know it's not that. What would you guys look at in the Live Link if you were me, to see if I could find the problem.

Check you maf voltage and o2 levels. You might be able to tune that out or raise the idle a little to make up for it.

Any time you change cam(s) there are items that need to be adjusted within the tune depending on how aggressive the cam is.
Most likely your car is using too much spark to try and adjust idle because of the new profile. Typically the idle spark gain has to be reduced to help this. The amount of air through the ISC valve usually has to be worked with in neutral as well.

The stg1 cams shouldnt need any of this , havent had to change any of that till stg3 and then only slightly , Im wondering if you need to adjust the cams , meaning if you have adjustable cams and the cams are off some then that will hurt your idle BIG TIME
