I have read somewhere of someone with a 1NZ-FE engine and achieves over 23km/l. This is after mapping for the engine to run the most lean, then they introduce water into the engine to prevent detonation. @introvert, nichanue step by step how to go about this. Photos ni muhimu if any
That must be one hell of a weak engine
…what makes it weak? fafanua…
its still 1NZ -FE, the compression ratio is 10.5:1. Output is 81.2 kW (109 hp) at 6000 rpm with 141 Nm (103 lb·ft) of torque at 4200 rpm. The redline is 6400 rpm.
IMHO, not worth it. plus if you cannot comfortably fuel a Corolla, you probably should not own it in the first place.
I concur, or go for a Terios Kid
…not a billionaire, so nichanuliwe…billionaires kaa mbali
This will be in the end more expensive.
BTW 1NZ FE is not efficient on cars like fielder, corolla saloon, premio, allion and other heavier cars exept if unashindanga tu kwa jam. It does well on the super lightweight probox and smaller vehicles. Its also very poor in fuel economy over long distances when you are laden. kama ni corolla you would rather have the 1.8L naturally aspirated or the 1.8L turbo. You will never need to floor the accelerator. gas utakuwa tu unaguza. Toyota has the lightest cars around except for the newer models running on CVT transmission.
what is mapping, n how much is it,
that is absolutely weak. 141nm can never give you whiplash and 109hp is laughable. but it’s good for a city runabout.
running lean is more dangerous than running rich. you’re telling the air pump to pump more air than it possibly can.
but this idea of water, sounds new to me. meth, yes. water…?
fondling your ecu to change normal operations and increase it’s ability to handle more pressure.

[li]Water injection requires a separate tank to store water which may increase the gross weight of the vehicle which may in turn increase the fuel consumption.[/li][/ul]
[ul]
[li]Water, also may corrode the components of the vehicle system which may require special treatment or coating of these components.[/li][/ul]
[ul]
[li]Controlling the water injected is also critical. Yes, correct quantity and apt timing is necessary for water injection to be successful. So, special controls and programs needs to be added to the ECU ( Engine Control Unit).[/li][li]Water and Steam injection causes the exhaust system to rust. The only way to prevent this is to allow the engine to run for a few minutes with the injection turned off. There is only two ways to do this, manually turn off the injection before you arrive at your destination or have the car equipped so that it runs after you remove the ignition key and turn off with a delay timer. Both of these schemes are not user friendly.[/li][/ul]
BMW waliweka this water injection system kwa M4 GTS i think for every 37 miles lazima ufill the water tank.

For? Cooling the charge or what? In combustible sections of the car?
…not really for cooling though engine operates at a lower temperature…it ensures powerful explosions giving better economy yet more horse power. Its a technology that has been since 1940’s
…so, what amount of HP do you drive around kama hizi pro box zote, nze, runx, rumion umesema ziko na engine ya city runabout
Time ndio imenilemea, but there’s a 4.0 whose performance I will document after installing a stand alone ECU.
Why do you want to milk that Toyota dry? It’s already giving you better fuel economy than my bike.
…I want to learn more…please share
i have to read up on this. truth be told i heard it here for the first time.
i’m inching towards 300hp. it’s nothing compared to ochithunder’s car. maybe closer to crazywizards golf.
by standalone you mean separate individual ecu and not piggyback, correct?
explain in details…be more vivid
Yes.
