Here is the all new MAP / MAF Enhancer and Dual EFIE.
This unit let you precisely adjust both sensors voltage signal with a two 25 turn potentiometers. No need for two separate units.
The EFIE will not disconnect the oxygen sensor from the computer it will only add the specific voltage amount to the oxygen sensor signal; the computer will never detect this device. The MAP/MAF enhancer is driven by a microchip not a resistor this allow a more precise adjustment.
