CZ unit vs stock ecu
Does the stock ecu overwrites the CZ map after a while?..i searched and couldnt find an answer....also does the pre-loaded map have adjusted timing already?

"open" loops where ur just using all the sensors to calculate the A/F ratio..... however in "closed" loop, thats where ur PCM looks at the O2 sensor n will use that to calculate the air fuel ratio......
