IFR multiplier p12 5 cyl question

[ah206]

I want to run 80lb injectors on the colorado/canyon p12 pcm. Does the ifr vs volts multiplier table work? Ie divide IFR by 2 then enter 2 in the multiplier table.

im still pretty new to this but hopefully someone will correct me if I'm wrong. If your dividing the flow rate in half then your essentially entering 50% of the actual flow rate so in the multiplier your entering 1.5 to add the 50% back in, thats what i did with my p12 computer in my cobalt also with 80# injectors as well, although I'm still working out the bugs to get it near perfect its idling smoothly

If you divide by two then your multiple is 2 not 1.5. (80/2)*2=80. (80/2)*1.5=60

Yep half IFR and multiplier set to 2. It works just fine. Went with the 72lb ev14 injectors.
