give me ONE good reason to WHY IN ANY SENSE should even consider buying your item (which is a hoax to me - because you refuse to put logical reasoning and proof) when one can simply replace the worn out items to get original performance back.

and to top it all the original tune will not screw up the car.

What we have seen is that you only have a superficial knowledge on how old toyota systems work - and have a completely screwed up understanding of basic VR sensors and even have corrupted knowledge on thermal and volumetric efficiency of a regular otto cycle gasoline engine - hence also very corrupted knowledge of how an ECU adjusts fuelling, timing and emmissions.

I specially laughed for about a good 10 minutes on the one NE pin is used for positioning part while the other is speed. LOL - hahahahahahahaha - This proved your complete failure, anyone who does not know what a VR sensor is or how it works cannot be expected to know how an ECU tune can be modified.

It would be similar if you went to the doctor and for checking your pulse he checks your hernia and then gives you cough medication

I dont want to get in the discussion first of all i am too much busy these day's with our customer's second who ever you are I am not enforcing you to buy or try our product's. because you are too far away from us right now. and if you want to get in the technical discussion then you are welcome if you had some budget give me a call and can discuss the technical issue's.
Third You are to much knowledgeable person and understand the whole mechanism BUT you limited your self to the factory level and doesnt modify or try to modify any thing by your self other than relying on some aftermarket companies. because you dont had that knowledge and gut's to to experiment on your own vehicle to see what happen's when you alter the signal's and in reaction's what does the ecu do to it. so leave it.

Thatz enough my dear

U dont know even the ABC of Electronics/Electrical systems. i dont understand what u r talking about, U r just wasting our time

Jerk = d / dt (acceleration)
acceleration = d / dt (velocity)
velocity = d / dt (position)

so from position u can extract every thing

I have one more question for you or @xulfiqar :

how does the ecu know crank position...?

I don't think VR sensor can get position. what if it misses a few teeth of the gear due to some malfunction..? now positioning info is lost and ecu needs to reset?

Hmmmm its a tricky JOB

Different Engines use different crank / cam wheels configuration depends on make/model. lets consider an Engine equipped with 36-1 teeth Crank wheel & 1 tooth CAM wheel.

Basics:
36-1 teeth wheel means it has 35 teeth & 1 tooth is missing
Crank Shaft Speed = 2 x Cam Shaft Speed
4-Stock Gasoline Engine requires 720 degrees of Crank Shaft rotation to complete 1 cycle

There r lots of different schemes used for synchronization, lets consider 1

in synchronization process ECU synchronizes itself with the engine position. during cranking phase ECU searches for the missing tooth on crank wheel as soon as it detects the missing tooth it waits for CAM wheel pulse as it gets the CAM pulse it registers it as a TDC of Cylinder#1. This is the reference point of 0 degree.

the system is so stable that its almost impossible to skip even a single pulse @ 10K RPM. lots of noise suppression filters & back EMF inductive kick absorbers are employed. if in case it skips a pulse the Engine will cause miss firing or stop immediately etc but this happens only if wiring/connectors are bad.

Modern Engines r equipped with Crank/Cam wheel which generates a very complex pattern of pulses. compact 660cc Japanese engines r good eg of ths.

VR Sensor AC signal (Sine/Triangle wave depending on teeth) can be converted into digital pulses by using some dedicated circuity,

@xulfiqar....You Understand??? Your Knowledge Is Limited And Only Limited To Books And Factory Levels OK??? Make It Clear

Because This Is MAGIC ANd DOn't Get Into WAY....

[hameeds01]

@ accountist

In this case
Crank: 8-1 teeth wheel
Cam: 1 tooth wheel

Crank spins twice the speed of cam

[accountist]

@ accountist

In this case
Crank: 8-1 teeth wheel
Cam: 1 tooth wheel

Crank spins twice the speed of cam

but the sensor and the memory which stores the last position, is it on at all times?

Like how about I rotate the crank when engine is off.

So in that case how will it know the correct position ?

does it determine the position every time when you start it up? and then forget all info about position when you turn it off...?

during start up, the engine probably rotates 1 or 2 times before ignition, to get it up to speed and determine position...so thats probably how it works...?

hmm - guts have nothing to do with a cheesy cheap budget car like your production toyotas, mazdas, mercedes etc. - I have worked on the drive systems of machines that cost 1,000,000 times more than these cars, machines whose single payload is above 100 tons and their downtime is about 200,000 dollars an hour in cost. Speaking of this and what I was taught in school I dont think much can come out from what ever you are trying to do.

Why should one modify a system when all components are still in production and still available.

Dont try to get over yourself that you are the ECU ayatollah in the world. You might pull this off on the twin cities average "road mechanic" - But you cannot pull this off on anyone who knows whats what.

Your sheer misunderstanding of ecu logic and refusal to post any screen shot or even write a simple readout explaining it makes you incompetent in any logical sense. Or in simple words - your system is not proven technology.

You also said that your system works on diesel engines, I would love to see you offer this to a heavy lift or heavy duty mining firm. The machines I wrote about use about 30,000 dollars of fuel a day. If your system can improve economy to 50% then the firms can save 15,000 dollars a day, Please offer this as a package/one window service then we will see whose doing what. There are a few large excavations going on in Terbela - go for it - your system is their accountants wet dream

last position is not saved but the position is "determined" right there when the ECU is in start mode as the engine is spinning about 300 rpm only - lets assume the system does not have a cam sensor at all and only has a 4 pole crank sensor - runs paired injectors, and a distributor (meaning no coil over plug meaning no sync needed for per cylinder firing)

what happens is that as soon as the VR signal goes from high to low (about the 2nd compression load of the starter) all injectors are signalled to fire at once to spray quite some fuel while the base timing is called upon (about 10 degrees advanced) to make the engine start. The after start map (aka above 300 rpm and STA signal gone low) is then called in and the goes into the warm up mode (open loop) working on a set injector time and and the ignition timing is a bit retarded too to enable the O2 sensor to warm up (assuming single wire sensor) and also to ignite the cat.

The ECU then goes into closed loop once the coolant sensor signals that the engine is at normal operating temperature.

This is very basic - if you go a bit advanced - then the signal can be different, you can have a system that just reads a constant serrated wheel but have a TDC sensor (cam phase) or even 4 of them (4 cyl) - or you can have 2 misses on the crank trigger and then have 2 separate cam phasers (6 cyl engine) to make the engine see what cylinder reaches TDC - this then can be used as a basis to work where the engine is.

What we are seeing here in these forums is a glorified cng advancer and a universal elixir for any sort of car ever invented to be run on a control unit.

The Process starts as soon as the ECU get power, if u leave the key in ON position without cranking & rotate the Engine via hand it will try to synchronize but again it will reset the position status bcz cranking speed is too low for synchronization & there is no consistency in rotation.

In case if the Engine is Off nothing wil happen, as there is no power to sensors + ECU.

Yup it synchronize itself every time when u crank the Engine. there is no ignition & no fuel injection for atleast one complete crank shaft rotation (360 or some times 720 degrees) ECU only concentrates on synchronization process. as u know accurate Engine position playz a vital role.

Yup it forget about the Engine position once u turn off the Engine, it stores the Position track in a volatile variable, only it remembers LTFT & some error codes.

Yes it wastes initial 1 or 2 crank rotations

Lets assume Engine is cranking @ 300RPM, (Frequency = 5Hz, to complete one crankshaft revolution it requires 200ms)

During Cranking most of the ECU performs Batch or simultaneous Fuel Injection triggering & extended Ignition Pulse (High @ extreme advanced position & then goes to low @ extreme retard position). Once the RPM crosses the threshold of 400RPM everything becomes normal,
Fuel Injection: Sequential firing
Ignition: Constant pulse of 2/3ms
