This ECU is not a p07 Basemap It is a fully custom basemap
Vtec is not engaged to engage lean burn
just trying to clear up the information that is not correct
here is the TRUTH
ECU's for both VX and HX civic
lean burn in 3rd 4th and all of 5th
more aggressive vtec crossover for power in the top range
no O2 sensors at all are needed
safe A/F ratio's and no "on the fly" tunning is needed
Merry Christmas
