LS400 MAF sensor question

[Lexsurf]

Afternoon all

As some of you may know 89-94 Maf sensors for the 400 are rarer than rocking horse doodoo, when you do find them there from a breaker and blinking exspensive.

My question is will the Maf from a 430 work in the 400 factoring in wiring the diferent connector to the 400s wiring and fixing the 430s maf to aluminum tubing as opposed to using the 400s housing due to different screw placement and shape

Does the sensor give a monkeys what engine its in? or isit design only for the LS430?

 

Thanks all

Unfortunately the LS400 uses a different MAF sensor to most other Toyota vehicles of that age (Karman-Vortex design compared to the more common hot-wire type). The LS430 uses a hot-wire sensor.

In theory you may be able to use an alternative type but the ECU has specific mappings for the MAF designed for the engine so you would need some sort of convertor.

damn it, does that same fact apply to the post 94 mafs for the 400 the ones that look like torpedos with cross hairs? are they already hot wire?
