Default someone please review my tune (2.5i)

Could some review my log after a NA 09 2.5i stage 1 tune with 91 octane gas? for better understanding here are my logs after an ecu reflash/reset:

log 1 of 2, IAM started out at 0.5 and went up to 0.65 here

log 2 of 2, IAM reaches 0 and i get about -3 deg knock correction at some parts.

Please only log pulls, I understand there is sometime usefulness to logging just driving but after a flash just worry about what is happening when the car is under load. Go do a logs on a couple third gear pulls and get back to us. And don't do it immediately after the the reflash. IAM will start low and build up to 1 once IAM is at 1 then do logs.

ok thanks its very hard to log just pulls because I have to find time and give attention to laptop while driving. Also I have been waiting for the IAM to go back up, but it's just not happening. It's camping at 0.

for your convinience here is a cut out of WOT runs of 2nd log only:

When I was opensource you can use the defroster button to start and stop logging so you can focus on the road better. I don't know if this is the case for your car but try pushing the defroster button and see if it starts and stops logging. If IAM isn't going back to 1 switch back to the stock tune and see how that map does, if it also isn't allowing IAM to go to 1 you may have a different problem other than the tune.

ok so for the map with no ignition timing tune (only OL delay fix and AFR):

I did a WOT pull in first 3 gears and no knock. IAM stayed at 1.0. Total Ignition timing was about 24-25 degrees near peak power.

Seems about right. Sometimes issues with knocking arent the amount of timing, but the delta timing. Meaning the change in timing over time, smoothing of your timing map can significantly help this by making smoother transitions in timing.

Just something to consider.

thanks thats good advice. Do you have any suggestions for a read on these type of things? for that particular map i just advanced the timings under heavy load. The transition was actually quite smoother compared to stock. for example at 3200 rpm under 1.3g load stock timing was 8 degrees and under 1.2 and 1.1g loads they were 10 and 16. What i did was i made 1.3 g closer to lower loads for that RPM by advancing it to 10. there are 4 base ignition maps...someone told me one is for cruise one for AVLS cruise and two others for non cruise and NC AVLS. one of the tables has aggressive timings between 2000-3600 rpm under low loads. im just not sure which table is which and which one I should tune?
