The way I have been working on my Fuel Scalar table is as follows;
- Start with a base value for the fuel I'm running
- Get logs with as many different RPM/Load points as possible
- Look at STFT for those RPM/Load points and adjust as necessary
The problem is it seems the car goes open loop during periods of fast transition. So rather than pouring through logs to look at each data point and compare the actual AFR to the target AFR for that particular RPM/Load point I made a lookup table to do it for me (attached). Copy a log to the 'Log' tab with the same channels as shown (up to 1000 rows unless you edit the 'Main' tab), copy your AFR target table to the 'Fuel Target' tab (both axes need to be descending), and then you can filter the results in the 'Main' tab to your hearts content.
Maybe this approach isn't valid for some reason and if you think it isn't I'd like to hear why but I guess we will see in the logs. I should have my Innovate installed soon as well which should have a greater log resolution.
