Startup Problems
Ive been Tweecing for about a month now and have the MAF transfer pretty close. I have an 8LD using the A9S strategy. I have a problem when I start it. In the morning, after it has sat overnight, it will start just fine. When it is warm, it will start fine but either surge and want to die, or it will just die. After its running, it idles fine. I would say for the first 30 sec or so, it will want to surge. I set the idle using EA but it didn't help. What do I need to do? Do I need to zero out some columns in the startup fuel table?
Thanks, Clay

Re: Startup Problems
What size injectors? Any vacuum or exhaust leaks?

Re: Startup Problems
It has 30lb injectors. No vacuum leaks. There is an exhaust leak where the mufflers connect to the h-pipe. I dont think that would matter because it is behind the O2 sensors.

Re: Startup Problems
Correct, exhaust leak that far back shouldn't effect the O2's, will just sound like ass...
 What do you have your high and low injector slopes set to? Have you used EA to establish the slopes?

Re: Startup Problems
Prob. right, Lee. Just making sure nothing was screwy on the injector slopes...

Just a suggestion but try changing the 45 sec. row in the startup fuel table to all "0's". That is if no mechanical issues are present.

Re: Startup Problems
In my stock tune, the 45 sec row was already 0's. I changed the TB air flow back to stock and also the ISC neutral idle air flow to stock. Seems to be better than what EA sugested. I will mess with the startup fuel table and see if it helps.
