Review on Innovative Performance Power Programmer Toyota Replacement Parts : Engines & Engine Parts by Eduardo Long

BUYER WARNING! PLEASE READ THIS CAREFULLY BEFORE PURCHASING! AUTO TECH PROFESSIONAL CAREER IS HERE. Any tuner that doesn't connect to your OBDII port or multiple pre-1996 (pre-OBDII) sensors and timing systems isn't really going to do anything. It's essentially a resistor, a small device that burns up a certain amount of electricity. According to the instructions, you need to connect it to the IAT (Intake Air Temperature Sensor, the only sensor on the air intake or air box). This sensor provides feedback to the intake manifold pressure sensor (measures the air pressure in the intake). manifold) to check the readings of the mass air flow sensor. (Temperature and pressure are related to the volume/mass of air used.) If your mass air flow sensor fails and your engine still runs, albeit poorly, it's because your computer is reading the IAT and MAP sensors and mass estimated using the formula. They are difficult to measure constantly and instantly, and as a result, the engine does not work as it should. This means that your IAT sensor is used to constantly check the MAF sensor's digital reading and the actual reading. This means that with a running IAT, there is NOTHING you can do to improve performance. Nothing. Nada. I am posting this review because a 1998 Toyota RAV4 arrived at my shop 24 hours ago with a severe loss of power. This product was installed by the owner with little technical knowledge. For 5 months the engine worked very well, killing power and mileage. This poorly burned fuel collected as soot on its valve seats, causing compression to average 100psi. Usually 150-160. Now he pays $1200 for me to take the head off, clean and inspect, reinstall the valves and basically do the head gasket in addition to rebuilding the cylinder head. Six months ago at the last oil change; This completely brand new and UNTREATED engine has clocked up over 350,000 miles with pristine performance and is as smooth as a 50,000 km domestic engine. This "tuner" only needed 2,800 miles to do the first major overhaul on this engine.
