Installed on @David228cx civic and feels way better, the clutch actuation is more precise and there's minimal engine movement when you left the accel pedal. Vibration is more noticiable at low rpm but once the car is moving the increase is minimal. Definitely waiting for mine to arrive and install.
No, as long as the owner use a stock maf housing or a well matched aftermarket one there should be no problem. If someone detects too rich condition get in touch with derek, remember adjust the gas type in the datalogs or it will register richer than real.
Piggybacks work, the thing that concerns me most is Ignition control. How can it work safely, optimal and consistently without controlling it? Am I missing something? I still feel more comfortable with a safe tune than a piggyback, which is also less customizable.
My trims are always between -7 and -3, sometimes go to -10. Consider replacing (or at least check) the stock filter before 20k km if there is too much dust/polution where you live. Im using a washable K&N filter, because the stock filter was getting clogged and stealing turbo spool speed down...
