A while back we were arguing here whether a car engine could meet modern emissions requirements with an ecu. I believed it was probably possible even if extremely difficult and there was rather unanimous disagreement. I wonder if anyone seeing this would change their mind a bit.
And yes, I do know what a modern car ecu does.
- dtgriscom 5y agoYou aren't clear; are you wondering whether an engine WITHOUT an ECU could pass emissions? If that isn't it, what did you mean? (Every new car passes modern emissions with an ECU...)
- userbinator 5y agoI agree it's possible, after all careful tuning of a carburetor can produce great gains in fuel economy and/or power; but of course most people doing it aren't interested in emissions.
- dharmab 5y agoI think you could pass emissions, but you would likely have to compromise severely on price and performance. There are carburetors such as Lectron (https://www.lectronfuelsystems.com/ https://www.lectronfuelsystems.com/) that have some capabilities you would normally use an ECU for.
