Camcons were all the talk a few years ago, but good luck finding someone to properly install it...

whats your mechanic say? is it running rich? could be your lambda or maf ? I'd try and get the original parts checked out before buying parts especially if your selling.... just my two cents :)

well what i was told ( 3 years ago) was if ur gonna go intake and exhaust mods you should adjust your air/fuel to compensate or you cud be running rich and lose power as a result...

in too minds really, i'd like to sell the car and buy something 2 litre turbo but at the same time i love my tezza!!! :lol:

The factory tune is always very conservative. This protects the engine if low octane fuel is put in it. It also ensures it's reliable, fuel efficient, meets emission standards & doesn't wear prematurely.
With an AFC you can squeeze a few extra HP out of an engine by tricking the factory ECU into putting more or less fuel into the engine.
Only problem with using one of these on an Altezza 3SGE is they have closed loop type ECU which will gradually over ride any piggy back AFC. The only way around this is to reset your factory ECU on a regular basis.
A replacement ECU like the Apexi Power FC would be the ideal way to go.

Here's a bit of research I did into piggy pack AFC a while back http://z4.invisionfree.com/lexusaltezza ... c=6867&hl=

HKS AFR in my car.
Useless device unless you like digital displays showing your RPM.
The Toyota ECU overides the piggyback unit.

It has been replaced by the Apexi neo but I'm sure you could pick one up second hand for 150ish maybe less?

If the toyota ecu is just going to override it eventually is there any point? i was tol that having an air intake and an exhaust i really shud get an air furl controller cos with those in the car the mix ain't right? but if the toyota ecu has this "learning" capability shud it not adjust itself to the mods?
