Thanks
@a91what for the fan control suggestions. I tweaked my settings for delay of 200ms and duty of 20% since at 100ms and 10% it didn't seem to try to catch the RPMs at all. This seemed to help keep the RPMs up a little higher than it dipped previously but I think it could still be improved. I have the idle up target increase set to 100rpm, do you think that needs tweaking as well?
Current fan control settings:
So this week was pretty good for driving the car to/from work and datalogging. I've attached the most recent logs zipped up and the current tune used for those logs.
I had more logs than these from earlier in the week and ran VE Analyze against them, loading multiple logs into MLVHD. Where I'm a little stuck/nervous though is applying the VE Analyze changes and smoothing the tables. I did this for the earlier logs and when I drove the car I was paranoid that it might have pulled more fuel than was safe since I did notice the AFR numbers leaner than before. So I reverted back to the previous tune and that's what the attached logs are from.
So with that said I'm hoping that I can get some advice on how to properly do the fine tuning phase of driving, datalogging, analyzing, applying changes, smoothing, repeat.
To maybe help people following along, here are some screenshots of the before/after VE Analyze for the logs and tune attached:
Before VE Analyze:
After VE Analyze:
As you can see, it's almost exclusively was pulling fuel out. What I'm curious about is if I should be careful about the changes it suggests under boost, and if I should be using a min-max MAP filter like I have set for the idle/RPM filter.
Additionally, is there a better way of smoothing out the VE table after accepting the VE Analyze changes? With the earlier logs I had been manually adjusting the neighboring cells to make smoother, but I also came across an excel spreadsheet someone made over in another forum that allows for automatic smoothing along with smoothing factor. I can attach it here or post the link if anyone is interested unless you think it's a bad idea to use a tool like that.
Anyway, thanks as always and I very much appreciate any help or advice you can give me on this part of my tuning journey now that the car is driveable again
