I found the following thread which is an interesting read. http://www.supras.com/~riemer/lexusriemer/lexusnotes.html
It talks about using the lexus v8 air flow meter on the Supra 7MGTE engine. The effect of this is for the engine to use more air without the computer realising it (until it detects the lean burn) without more fuel. They then use larger injectors which seems to allow more air and fuel without the computer believing anything is different to the standard setup. At least that is my interpretation of the article - someone please correct me if i've misunderstood!
What I want to know is...
Is this relevant to the 1UZFE ECU? Can it be tricked the same way?
Also there is talk of the 1uz engines from Crowns having smaller injectors than the Soarers. Is there any negative effect in swapping Crown injectors with Soarer ones while using the standard ECU?
