make your statements. The E-Manage actually taps into the injector output wires from the ECU IE it makes changes after the ECU in that regard. The E-manages actually cuts the output the coilpacks to make timing changes.
Yes doing the changes in the ECU is better. But don't confuse E-Manage with just being a basic unit like the AFC or AFR.
Oh yes it can also make changes via the MAF signal.
BTW what do you think the HKS VPC does? How many cars do you think have made over 800RWHP with a VPC?
Not bashing on you just asking you to research a bit more before blindly responding like you know what you are talking about but really don't.
And yes once again doing it in the ECU is a better way. But the others way have worked and are proven and have made huge amounts of horsepower.
