Got a p1514 today while in speed density?
I have an 02 z06 with a fast90 and an ls2 throttle body, headers and an f13 camshaft. I have it in speed density so I can get my ve table straight. Well this morning I was driving it to work and I was winding out 3rd gear and the engine shut off and I got a reduced engine power in my dic. Well I started it back up and it ran fine. When I got to work I checked my dtc's and I got a p1514. I did a search for it and found this thread https://ls1tech.com/forums/showthrea...ighlight=p1514
but this does not help me though because I have hptuners not efi live. If anyone can help me with this I would greatly appreciate it!!!!

I am still having idle problems and I just can't seem to shake them. I have tried my best with the etc scalar to get my dynamic airflow and my idle desired airflow to match and it does for the most part. My stit's and ltit's are well with in range and yet it still want to hunt idle when I am coming to a stop and when I press the clutch in. It dips and surges at least for 5-8 seconds after I press in the clutch until it finally finds the idle. Does anyone else have any suggestions for me. Thanks.

You may end up going a little higher depending on your mods - I had to take one Vette up 25% to stop the reduced power. Just try it and see if you are in the clear.
As for the idle, try adding a little air to the cracker table in the rpm/vehicle speed where you are experiencing the problem. You can also adjust the decay rates if need be, but I generally solve it with a little air. Whatever you do, only make small changes and only change one table at a time (i.e. don't add air and change the decay rate at the same time).
You may also want to check the timing in the area where it is surging at idle - around 24* usually works well.
Hope that helps!

You def. had the right idea on where to go in my tune though!! I have my idle timing right at 24* too.
