Hi Robert,

First sorry for giving you a Thailand web site but that what I found which is similar to my car ,

SUV  TOYOTA  LAND CRUISER   2.7 VVTi PRADO

This model is sold in Asia and in Singapore we have only 25 cars like this

PRADO PICTURES

I’m running now with hh0 1.1 litter per minute the map sensor installed and still nothing happening except that the motor warning light is on. Do I need EFIE ENHANCER O2 OXYGEN SENSOR ADJUSTER as well?

Hi Robert

The wire is connected correct I send you the numbers last time and you ask me to try to go on 8 so I have tried to go on 6 to 10 when change I can feel it but no change in saving still doing 5.4 Km per litter (13 mile per gallon) when the hho is on, the motor light will come on and off. Measure it for the last two weeks that's why I asked if I have to do something with the O2 sensor as well

thanks Frank

the prado is made in 2003 and have a map/maf sensor confirm with toyota garage, its connected to the green(signal), green/black(5 volt) and black (ground). the numbers that i mesure on the map is

switch on motor off
city  scale 0  = 0.2v
                5  = 0.3v
              10  = 0.5v
Hwy         0  = 0.2v
               5  = 0.4v
             10  = 0.5v
motor on
city scale 0  = 0.1v
                5  = 0.3v
               10  =0.4v
Hwy         0  = 0.1v
               5  = 0.3v
