Is the EGR delete a performance gain or loss?
EGR delete without a remap of the ECU will give no performance benefit but will increase emissions. But it does simplify things greatly. A remap is unlikely to give collossal gains in power, but there will be some. Either way it’s not an engine killer.
What happens when you close the EGR valve?
By allowing cooled exhaust back into the intake, the combustion temperature of the engine becomes lower than the 1600°C. I should note that at idle and full throttle, the EGR valve is closed, and does not allow any exhaust into the intake.
Do you have more power with too much EGR?
If the same amount of heat can generate more pressure, you have more power. EGR has been shown to slightly improve MPG. Too much EGR and the flame propagation characteristics suffer past any possible gains from the “souped-up” expansion medium. You must log in or register to reply here.
What happens when you disconnect the EGR system?
What effect does disconnecting the EGR have on the ECM (or PCM) when it is calculating the air-fuel ratio for the engine? If the ECM leans out the mixture, that could cause the engine to run hotter. EGR delete without a remap of the ECU will give no performance benefit but will increase emissions.
How does the EGR valve affect Wot performance?
It has absolutely 0 effect on WOT performance and I’ll explain why in this article as well as tell you how clever this little valve really is. The EGR valve does not open under heavy load (I am unaware of any exceptions) and therefore, you will not be burning exhaust gasses while at wide open throttle.
How does the EGR valve save you money?
In fact, it’s more about saving fuel and as a side effect, reducing emissions. In essence it “shrinks” your combustion chamber when the need for power is low. It has absolutely 0 effect on WOT performance and I’ll explain why in this article as well as tell you how clever this little valve really is.
Where is the EGR valve on a car?
The EGR Valve (Exhaust Gas Recirculation) valve is found on almost all modern engines and is considered part of the emissions package of your vehicle.
