Hi Deankdx. My 1UZ-FE is from an Ls400 or Celsior,but the intake is the same as yours.The dual throttle body (DTB) can be removed and replaced with the GRA carby.An adapter is req'd to bolt to the manifold. The plugs and wiring in your photo are the main TPS and the sub-TPS.The sub-TPS (closest...

There seems to be some confusion between a MAP sensor and a Barometric sensor. If you are looking for a MAP sensor you won't find one as a Karmann Vortex is used for the AFM.

According to my factory ls400 manual, the ecu has what is called a "High altitude compensator sensor"(HAC). The sensor is used to detect atmospheric (absolute) pressure.Changes in air pressure cause changes in air intake density and therefore the air-fuel ratio. The ecu uses this input to make...

Hi Deankdx. On a trip to Melb. back in 2001 I took the complete upper half of my 1UZ-FE intake manifold to GRA. They recorded all the measurements off the intake/throttle body flange and made up a 90 degree bend to mount the S440 gas carby parallel with the engine.The TPS was not a problem and...

MAP sensors and the Airflow meter (AFM) used on the 1uz-fe operate on different principles and have different outputs. The AFM is of the Karman-Vortex type. Inside the AFM a pillar in the airflow creates vortices or turbulence (as seen behind fighter jets),and these cause a thin metal foil...

Contact Michael Vidau at MV Automatics: 1 Stirling Rd, Blackwood.SA. 5051 Phone: 08 8370 0430 Fax: 08 8370 0431 I had Michael service my Lexus gearbox earlier this year,replacing seals and fitting a mild shift kit.

It strikes me that Volvoguy threw you a line, and you all bit like a barracuda. Anyone that puts his location as "asshole" is not worth talking to and shouldn't be allowed on this forum.

Dan, I was taught that shielding should be earthed at one end only, otherwise you can get circulating currents in the shielding causing interference.
