So I need to get an E test done, and heres the questions i have. To run the test with the chip or not to? The only mod i have is injectors. Are the ecu's in E30s smart enough to learn to adjust the injector bandwith, or is my car running way to rich? As for the chip itself and reading threads, it sounds like the chip should lower HC and CO but raise NOx cause its running leaner than factory. Has anyone done an etest with a chip in their car?
Does anybody have any thoughts for this?
