I can verify that Milzy's works on both the 3400 & 2.4 but I'm not sure on the eco.... only complaint i have on it was my holes that bolt to the motor were slightly stripped(bought it used )but i used the be next size bolt and it held great on my 5 speed.... i haven't driven misty enough to really test it though haha
