The mkIV Supra has TWO Lambda Sensors (on the ONE cat)...

the "second" sensor (AFTER cat') IS a Lambda Sensor, but only

LOOKS at the resultant gases... after decatting the Supra the

Management system works PERFECTLY ! !

Why is the Lexus (SORRY, Toyota !) any different ? ?

Can we hear from anyone who has actually decatted

a 400 or Celsior ? ? ?.....................................

Could someone explain the different types/models ? ?

I fancy (some time in the future) one of the 3.0 TT models,

is that a Aristo Vertex ? ?

or what ? ?

in other words, what FAST versions are there

(Supra TT-type fast, that is !)

I decatted a 1975 Imperial

a WHAT ? ?

Did they HAVE Cat's back in '75 ? ?

NEW Celsior owner (my Dad), couple of queeries (!) - no English Handbook !:-

Why TWO washer bottles ? ? (one for de-icer perhaps?)

Is the ECT button by gearlever for 'MANU'-changing or what ? ?

(didn't want to try it before we know !!)

MAY change Dad's oil (&filter) straight away, even though they

said they'd done it............

Any 'words-of-wisdom' about too high / too low oil grades for the 4.0 ?

I'm thinking ~ Fully/Semi Synth' ~ 10/40, 15/50 or is 5/40 OK ? ?

FatS.

Anybody got an ENGLISH instruction manual/booklet

for this THING ? ?

My Dad's Celsior has one fitted to control the suspension,

but,

the manual is in Japanese ! !

YES, any car PRE-1992 is before the Cat-Test for MOTs...

I suppose, STRICTLY speaking, you're STILL not supposed to

tamper with 'emmisions' of a vehicle ?!

but, NO the car will NOT be 'Cat'-tested at it's MOT

(wether the emmisions will be too high for a normal test is

another matter ?)

As my Dad's just bought a '91 Celsior, I'd be interested to

hear if anyone else has de-catted their LS400 yet TOO ? ? ?
