Hi guys, the pdf says it cannot be opened, I'm after injector data values for a 7MGTE, [email protected]

Here are the timing details for some of the Toyota injectors when using an aftermarket ECU which utilize peak & hold.
Closed (T<ms) below this point no fuel flowed, above this point a small drop of fuel becomes evident
Fuel Flow (T>ms) At this point fuel flowed
Fully Open (T=ms) At This point the injector was fully open and you could see the difference in flow
Coil Saturation Time (T=ms) No difference to fuel flow but this is the point where the injectors are saturated, meaning the magnetic field is at full strength and the current draw is maximum.
Approx Closing time T=ms This was measured with the oscilloscope and only and approximate time was recorded
It was made up of the field collapse & pintle shut time, while testing these measurements were done at coil saturation in practice as the ECU will switch the holding current so the field collapse will be faster giving a faster overall closing time.
Min Hold Current (Off <mA)
Once on the injector will close if the current falls below this level
Pull in Current (On>mA)
The injector will turn on when the current is above this level & this is the ideal holding current level
Max Current I=V/(Z+R) (mA)
This is the max current under test conditions
I am doing a 2 more and will post them up shortly.
7M GTE 440cc Low Impedance 23250-42010
4AGZE 385cc Low Impedance 23250-16061
3SGTE 540cc High Impedance 23209-74200
These Files are just copys of these tables above

Thanks Paul
Hello.
I will try and find these PDF and update.
