be aware that when i did the low pulse adder tables for the X, I stuffed up the axis/def..
it should be 0x41 (ie 65 elements) not 41... so the table should be a lot longer...
you can still use the same address, but use this as the def:
<table name="Low Pulse Width IPW Adder" category="Fuel" type="2D" level="2" scaling="IPW_Adder_div_2">
<table type="Static Y Axis" elements="65">

MFRED, can you tell us if the FIC 1650's were low Z or High Z?
I am assuming Low Z.
Also, do you find that the small the injector, the more IPW Linearization is needed, or is it the bigger the injector, the more linearization?
Thanks,

Sir, please read this thread. Very informative https://www.evolutionm.net/forums/ec...ion-table.html

Different combination of mods make injector behavior better or worse.
I use other people's experiences in tuning big injectors and most of the time it works.

So I was curious as to how this is calculated.

[QUOTE=Raceghost;11692483]Thank you, I thought they were low Z.
FIC 1650 injectors actually come in both high Z and low Z flavors.
The older Blue Max low Z version has a fat body like this - and can be difficult to tune at idle on pump because of high base latencies:
The newer high Z version has a narrow body and looks like this:
