Camry & Solara LoungeDiscussion area for every generation of Toyota's family car, the Toyota Camry. Lexus ES250/300 owners welcome! Topics of discussion range from fuel economy, safety, modifications, performance and more.
To tune your ECU, you need some sort of piggyback device like the S-AFC or the SMT-6. It requires extensive knowledge of how the engine works and what sort of modifications you need to provide optimum performance. Don't bother with VENOM/JET chips. By the time you need performance ECU tuning, you should already have done some serious mods to your car that need it.
Considering a Venom/Jet chip will cost you ~$500, use that money and upgrade your exhaust. Does the small Y-pipe apply with gen4's? I had some good gains replacing mine.
yup...the restrictive y-pipe affects all the gens of 1mzs....
but even piggy backs don't work very well with the ecus that come with the 1mzs.....it actually doesn't take long for the ecu to work around it- though I suppose one way of dealing with that is by periodically resetting your ecu
even emanage eventually gets overrideen by the ecu- what you would need for real applications (such as extreme amounts of boost) is a standalone
Offtopic: where'd you get your perfromance y-pipe, sanengo? only jp performance makes headers for the 1mz and also makes y-pipes too....and there are 3 of us in Canada that got custom ones made by ultimateracing

I have a 3VZ-FE, mine was installed in a shop outside Ottawa, Ontario. The name escaped my memory. It was done 5 years ago and I remember it was a bosal header and custom welded down pipe. According to my father (who owned the car at the time), it was half an inch wider than stock. The entire exhaust system was replaced because salt and pebbles ate away at the old one and made a nice little hole for fart sounds to emit out of it.
actually.. the 1mz one doesnt look as bad as the 3vz one

Ok, anyone care to explain to me how the factory ECU will over-write an S-AFC II?
The S-AFC II tricks the ECU by using the intake signal (if it's MAF ,MAP, AFM it doesn't matter), into thinking that there's more air/colder air than there really is. It does this by altering the signal sent from the sensor to the ECU.
Now if somehow you think the car will realize this, I'd love to know. Because a little narrow-band o2 sensor isn't going to detect much in the way of a/f ratios anyhow.
So, in reality, resetting it wouldn't really do much but screw up your basemaps again.
