When your vehicle is registered as a private one, you add a Hackney carriage permit if it were to ever be engaged in commercial transport. That's the provision of the law.


Meanwhile a friend of mine who uses a RX300 Lexus meet a mechanic who connected two "resistors" or "stepdown" to the fuel injectors to reduce fuel consumption and its working perfectly. Any long-term side effect on the engine out vehicle performance?

This will be an interesting topic that's why I moved your comment here.

Intectors operate on pulse, short and long pulses, dropping the voltage would it distort the spray pattern ? Let's discuss.

Thegiftedone more pics please.

I think it's all in the head

let's see the connection first and the resistors in particular

That's how they spread coronavirus to cars

I do not claim to know how the injectors work but my lay man understanding is this.
Pressure is fixed. Volume injected is dependent on the length of time the injector stays open which is determined by the ecu . The ecu monitors the efficiency of its actions by monitoring the air flow meter reading, the air fuel ratio meter readings while factoring in other variables like temperature, load, etc.
Does the injector have levels of opening like on a scale of 1-10 governed by the ecu? Cos I would like to think this is the only way a resistor can affect the volume of fuel injected by limiting the voltage flowing to the injector causing it not to open fully and reducing the quantity of fuel injected.

To the best of my knowledge (my knowledge which may not be correct), the injector is a on or off device. It's either open or close. It doesn't have levels of opening like say a flow control valve.

If that is true, then I struggle to understand how a resistor is going to achieve the fuel saving being discussed.

Following.

I'd like to see a picture of the setup by the way.

Inception:


It is PWM (pulse width modulated)

Billiebaba:

Injectors are not pulse width modulated, they are more like mechanical switches like that of relays.

Please I have a 2016 corolla that keeps misbehaving.
Some nights ago it just develop CEL and trac off light and started vibrating well well.
I off the car and start and it disappeared and I travelled and left the car at home.
Came back last night and drive the car again at 80mph the light appear again and refuse to go off.
I know I should scan but I really don't know good japanese techies in phc.The ones I know really bleeped me up last year as I got a jap car and I am scared to go there again.
What could be the cause and any techie any one can recommend for me in phc to do the job?

Please help a bro.

Scan and post codes here, we'll help you.

Hey Maribel, couple of questions: are you covered by warranty? is there any loss of engine power? is car running normal? Please note Trac Off light will show due to oxigen mix issues (no relation with traction control but that is the way they show this). I got the same issue (Corolla 2015, 67000miles) after putting some gas. Check codes: P0171 System Too Lean Bank 1. This means oxigen sensor on bank 1 detected and issue. Next time I filled up the gas tank, I made sure cap was tighten. Code was gone. If you are paying for the repair and car is running normal, I would suggest to cancel the parts order for now. First make sure fuel cap is tight or just go ahead and fill up the gas tank and make sure you tight the cap. Trac off warning will go away after some driving (wait at least a full day). Let us know how it went.

You may want to run through this page( https://www.cargurus.com/Cars/Discussion-c21610_ds639052 ) and also try out this suggestion pending when you can run a scan

You can contact chuks 07017081067 for a scan or MrFord on nairaland.

Billiebaba:

Forgive my memory, I just got it clearly now. I'm being confused with duty cycle of electric motors as their speed is controlled by the percentage duty cycle and forgetting that injectors duty cycle varies the amount of time it will open, thinking it only controls rotary related components. I agree injectors are pulse width modulated.

My answer is in two parts:

1) I've been to Gate in Ibadan, some of those primates there can do impressive work. Impressive as in it will actually work but typically not for long. Naija standard issue stuff.

2) I personally prefer carburetor (yeah I'm an old Dog) because you can modify behaviors by changing jets, accelerator pumps and/or converting ventures, but when fuel injectors started to become regular issued some shops opened up locally (SoCal) that offered injector modifications. So I know injectors can be made to flow more or flow less. I never tried to understand what they did but was only interested in getting sets of matching flow injectors.

Anything is possible.

nwanneni:
Wheew,finally...
I got in contact with mrford today and had my issue resolved.
So for those who know,I have been having issues with my Corolla as check engine light and trac off light illuminated on the dashboard and vibrations followed.
So I got in touch with Mrford here on NL through rationalmind and he came,almost punctual(traffic maybe) and scanned the car and it appeared cylinder 4 was misfiring.
Did his thing and it's all good now with dashboard showing no single light.
I will like to recommend him to most of the phc guys here as I can vouch for his sincerity,humility and professionalism.
It's(cartalk) getting better I guess

I met with him on Monday.. I drove to his house and he checked my fuel level sending unit.. After diagnosing my Car he said i should go and drive it for some time.... I asked what was his charges and he said i should go... It was like a dream to me here in PHC where someone will do that for free.... I didn't leave until he collected the little I have for him.... I just wish he will get a nice space not too far to the main town...
