Post log so we can also see ignition timing.
Post log so we can also see ignition timing.
No log to post but I think I nailed it. I noticed with messing with my IAC and tps I had a high idle until it war warmed and it was running 10 degrees timing. So I looked at the idle over speed error from factory pulls a ton of timing if the idle is high. Dropped that a but and it made it better but still a hard start. After adjusting a few things and making it worse I decided screw it. Let's toss in a stock ls1 VE and cranking VE. Fired up and ran perfect. Let it cool for another 2h or so and it's currently -3*c and it fired right up. It seems to crank. Longer but fires and idle. So now I need to start over with a new auto VE. I'm also going to look into the commanded afr. I know it's modified from stock. Maybe i have been tuning to my o2 Corrections to an improper number this whole time. I've been pulling from my VE all the time BC my ltft were always pulling. I may mess around a but again tomorrow. But next week I'll be in Chicago for a few days then dealing with my wife's car at the body shop since she was rear ended. May not get any seat time for a week or so.

Your minimum transient fueling is too high. You need to search this site for the {B9021} cax file. It will give you access to that parameter in your tune. Lower the minimum transient fueling to the same value that you've set in B4003 and B4004.Originally Posted by jay_rich
working on that now. I cant seem to get the cax file to work. keeps giving me that error to turn on the option etc.
Fired it up first thing this morning, ran like a champ! I cant believe all that BS from not using a factory VE. I even did an autoVE on the car last year. Must have been all over the map from having my fuel pressure a tad higher.

When you put the cax file in your calibrations folder it will then show up as an extra parameter in your tune file under Fuel > Injectors > Parameters.
I put the one for mine in the cax folder and renamed it 02020003 and it prompts me to go to view - properties etc. I edit to allow the cax. But b9012 etc doesn't pop up

If you can't get it to work properly then post your current tune file and I'll lower your transient fueling for you.

Now that's interesting. Can you post the cax file you downloaded?
Here's your tune with the transient fueling fixed.
