OK end of the testing, another 2 days have gone by since last test so PCM is fully relearned after the VE tune was installed

Results of today, exact same performance expected from a mostly cruise drive in same weather as 1st testcase, so NO gains from VE tuned.



If we compare the fuel trims and MAP before VE tuned we see what should be. cells 1 and 21 are decels and should be lean because PCM to conserve fuel will reduce injector flow while there still is airflow



Now look what happens when matching VE table values to the real airflow and now we see cell 21 is super rich when it should be lean



In all testcases VE tuned was a negative and trusting PCM to make use of the MAF is the best path for good running and performing powertrain
