These things are gimmicks, no better than the air intake temp sensor box. Yes they will make the throttle open more than where your peddle actually sits, but they don't make any more power. Does it matter that you reach 100% throttle when your peddle is only down 75%?
You need to do something to the ECU to change the way the throttle opens and if it gets WOT at low RPMs. Forcing the plate open to 100% at low RPM with something like these devices doesn't change the fuel or spark down low, so the ECU freaks out and does weird things. You have to adjust the parameters in the ECU to take advantage of it.
You're better off just slapping a bunch of neon lights and stickers to your car.  |
I hear what you are saying but at the same time, fuel/spark are referenced in part off tps, not off the gas pedal. So as the plate opens, the ecu reading off the tables it should be relative to the tps it is seeing. Hiding the air temp sensor is different altogether, as you are now feeding the ecu a false signal. My understanding is that this is not altering the tps feedback to the ecu in any way, it is strictly manipulating the ratio of gas pedal to tps movement, which really is a different thing.
