Injector Dwell time 2010+ F4

Does anyone have access to or know the injector dwell time for the upper and lower F4 injectors in a 2010+ bike?

I am looking for the dwell or lag time and voltage compensation table, there isn't much available online when searching by the injector model numbers. The only thing I know is that it is a licensed bosch style injector with a denso style plug on it.

The injector dwell is set by the ECU.

What he said. ^^^ You will need to read the ECU map.

On the Jap bikes I am familiar with the secondary injectors do not spray at all below certain throttle/rpm points

I used to be fast....now I just dream about it.

the injector dwell, lag, or dead time is a physical characteristic of the individual injector itself, and it changes depending on what the voltage applied to the injector is. You set this value in the ecu, but it must match the physical characteristic of the injector, or you tuning parameters and compensations will not be accurate.

The literal definition could be described as the time in ms below which the injector does not fire, it is used to define the lag between when the current is applied and when the injector actually fires.

Al, I think you'd have to get that from the manufacturer website.

First place i looked, but to no avail. That is why I am asking here, in case one of the members at the pointy end of the stick on the electronics end has access to the information. You'd need this information if you were mapping an ecu that wasn't initially set up for an F4, so something outsider of a microtec basically.

You should read the part numbers of the injector and post them here for anybody to be able to give a usefull answer.
For example B4 750's Magneti PICO IWP048 has a deadtime of approximately 0.808ms @ 13.2V. and a linearized correction of approximately 0.115ms/volt.

What brand/type ECU are you setting up? Is it a fully configurable ecu? Does it support switching between 1,2,4 squirts per cycle? There is a trick to experimentally approximately obtain the values.

One of the injectors in need ID'd is a Nikki EAT324

The ecu in question is an EMtron KV8, I can run the test myself this weekend, but was hopeful that maybe someone with knowledge either from racing or programming ECUtech might have the values already defined.

You could contact Doug Lofgren. He is in Minnesota and does that for a living. He is on the forum as @moperfserv

Whoa cool EMtron KV8 That i$ $omething.
Is the ECU also going to control the variable length intake tracts? They are vacuum operated OEM right?

Anyway i have no spec sheets of those injectors in my trash folder. It was worth a try but it is not likely that you will find these values on any forum. These injectors are so rare that practically no one knows them and professionals don't share them to protect their business. Do you have ignition coil dwell and spark duration times? I know the coils work between 1.4 and 1.7ms but i am curious to what the scope or spec sheets show.
