[QUOTE="2000wa250, post: 660463, member: 3399"] What I'm getting at is when you go to different injectors the timing adder needs to be changed. That's what got rid of the smoke for me. You don't eliminate it, you simply modify it to account for the injectors. The smoke is unburnt fuel and the table just needs minor tweaks. For me lowering it by 35% did the trick. You'll probably only need to lower it by 10-15% and it'll get rid of the smoke but still act as designed. What I meant by taching it out is with an auto trans you can adjust shift points to account for the cold oil, trans, and motor. With a manual there is no transmission tuning, so from my understanding they did it through this soi adder. Basically makes the truck a slow turd when cold so you bring cylinder pressures down and don't hurt anything when cold. Side effect is a little extra haze when cold. Bring this table inline with your base timing table and it goes back to working like it was intended and acting stock on cold start ups. Sent from my DROID BIONIC using Tapatalk 2 [/QUOTE]
