12594512 injectors on LQ4 help

[sam2317]

I'm installing 12594512 36lb/hr injectors from a 2008 flex fuel silverado and I don't really know how to convert the injector data from the e38 ecu to my p01 ecu

here is the tune file I want to take the injector data from
2008 silverado 5.3 flex.hpt

and here is the tune file I from my truck
1990 C1500 lq4 4l60e.hpt

Thanks to anyone who helps me

Old thread, so just in case someone else is looking for this info.

Discovered a 2007 Silverado 5.3 Flex fuel tune that is a P59.
So except for the missing Min Injector Pulse table all the data is there.
Min Injector Pulse table always seems to be the the same as the Default Injector Pulse table in the P01, so just duplicate it.

The flow rate table was the clue as these are commonly referred to as 36lb injectors.

Check it out.

I think the '07 Classic is a different injector, parts lookup doesn't show a cross to 12594512.
