You might want to start a new thread when you get into the details of it, either in the DIY section or perhaps the Technical section. I'm not a big fan of the EGR delete in general, as I see no reason to disable a functional. However, I'm impressed and intrigued by your use of an arduino.

Very cool NTYPE, I would love to see the .ino, could maybe adapt it to run on an attiny13a or attiny85 and make a really small and slick integration.Bought from: Night Wolf, bassrock234, sonikaccord, 904drACCORDMANG

i was under the impression that it would since the exhaust gasses richen up the mixture, when researching i came across some people warning of it and burning valves, probably just misinformation or people getting lean burn confused with it or something.Originally posted by NTYPE View Post

I would assume that a functional oxygen sensor would allow the ECU to compensate one way or the other, if the mixture were to change significantly due to the EGR delete.

What's the point of deleting the EGR? I know it help MPG but whats the downside of it?Comment

Can you get the values for the duty cycle and the corresponding valve lift voltage for that duty cycle? Good arduino use, btw.Comment

The exhaust gases have zero impact on the air/fuel ratio, unless you have mechanical fuel injection that pays no attention to the amount of air taken into the engine. The exhaust gases do displace some air, but they also reduce air flow, which the ECU detects and adjusts the amount of fuel injected.Originally posted by illinois_erik View Posti was under the impression that it would since the exhaust gasses richen up the mixture, when researching i came across some people warning of it and burning valves, probably just misinformation or people getting lean burn confused with it or something.
Exhaust gases do slow down the combustion burn rate, so perhaps in a marginal engine they might cause a bit of misfire. But this would be rare.Comment
