    Default Cold start tuning

    My 383 LS1 with ported heads doesn't start instantly like my stock LS1 did and I'm wondering which setting to address this. I don't think it's too far off as it starts fairly quickly but I'd like to get this last thing just right. Can someone point me in the right direction?

    I keep that one open in a tab on my browser and it's been very helpful in smoothing my idle. I've got my VE, MAF, and spark tables pretty close as well as my desired air and IAC. I guess I was just thinking that my cold start problems (really not a problem, just doesn't start instantly like before) were related to a specific table for cold start fueling.

    You can see how table B4307 has ECT on its axis.

    Thanks Joecar, so B4307 is critical to cold starts? I've got those values a little lower because I was getting a "cruise control" effect using the logged values from MAF vs. ECT.

    If you're getting "cruise control" effect, you may need to look at throttle cracker/follower.
