In the log I can see an area that needs some work. I'll post a little more info tomorrow. It's a little lean in one area in particular. Everytime the car hits that area in part throttle the afr drops to 16- 17. I'm going to try to fasten it up a little 1 increase at a time. It's only a 4 box area. I'll post everything that I do.
I know we're not done, Steve. I just feel a little bit more comfortable.
I see those area's as well, two of them are sustained lean spots, meaning that they just need more fuel added to them. Now that i have increased the aggressiveness of the EGO correction in the last tune revision You can watch the ego correction and get an idea of what is missing fuel, this is not 100% accurate however as the EGO is always playing catch-up to correct the issue. I also see that the Acceleration Enrichment needs work, it almost never activates during these small throttle adjustments.
Lets take a look at some different views from the datalog you posted....
This is a Scatter Plot view I like these to see how the engine is performing/used... On the left i have what I call the {engine operating range} If you zoom in you can see all the dots in the plot, this shows us the areas that the engine is using of the fuel map and what areas need the most resolution when building a comprehensive tune.
Now the view on the right is simple, A tune that is spot dead on will be a linear line from the bottom left to the top right.... If this plot has dots scattered all over then the tune needs significant work. Yours looks ok but notice how the line has a slight curve to it, this just wont do.... when this line is linear we will be done. This is a fun view to use to gauge the tune from.
This is called a Histogram, I have the same x and y axis loaded in as your fuel table. then i used ego1 as the z axis [z is the field you want to show in the boxes]..
some of these boxes show 104 7ect... that means the ego correction is adding 4% fuel to those areas on a consistent basis, this view averages the ego correction from the entire log file for each box. 100 means no correction and less than 100 means fuel was removed.
This is nice to use to quickly see what areas may need some adjustment.
This is the same view as above with your AFR on the Z axis. this is the averaged reading for each box from the log file. the boxes in green means the car was in that area often they have more 'hits' these numbers can be taken seriously, yellow is fewer hits and anything with a number but no color in the box ignore completely it may be based off of one reading.
I hope this info helps when looking at the log files.
