Zero flutter
two plugsECS website says it only uses one sensor but the pic shows three plugs? So is it really just plug D for the install?
Also any logging capability?
Has anyone compared this to a jb1/jb4?
Might feel similar to a JB1 but function wise its miles behind. It connects to the two boost sensors and alters the boost pressure seen by the ECU that way raising it. The ECU will then see a lean condition at the O2 sensor and run a fueling adaption called a fuel trim. It keeps running this cycle and at times the ECU checks if it can run its base trim causing lean spikes. The trims are also limited to 25% so on high boost applications the ECU will run out of adaption room and the car will run leaner.
The JB1 matches the unmeasured boost with rail pressure so this lean cycle does not need to happen with the ECU running in continuous adaptive mode.
The Dinan unit also does not see rpm signal so its triggered at a certain boost point and will hold the exact same amount of boost add through the rpm range.
Most piggy backs work similar to the Dinan and over time it has been proven not to be harmful to the car but in our books its not the right way.
Anyone else experiencing a decent amount of flutter on Race or Sport + between 2500 and 3500 or so?
I'm overly paranoid and have been using Sport only because of this.
This is a good point.After reading a bit more into it, this is why I switched to JB1, now upgrading to JB4.
Sport is 2psi, sport plus us 3 psi and race is 4 psi. Based on the boost gauge, I don't think the Dinan is different than advertised. The NPM makes more power
At the $160 or whatever price point this is a great buy. It was a no go at the original price. If you want more power and retain warranty the JB4 is the best bet. If you don't care about your warranty go flash tune. Simple.
Things are what they are this is a safe modest 4 PSI bump under the factory ECU settings. Want more than just go and do it the right way and go APR tune.
