I have 03 Silverado with a stock FPR on the rail. What would I use for the IFR and offset when using the Deka 80 data? I'm assuming the IFR would be the same all the way across but when logging fuel pressure, pressure changes under vacuum. Thanks

I'm looking for the Fuel to Wall data for some 365cc FIC (Clinic) injectors. I know it's usually left stock but I would like to see it for comparison if anyone has it. It's not on their website.
Anyone have the data for ID1000's, 4 bar, return style system.
I used the info off their site, but I think I might be missing something as far as minimum pulse width or something. My VE is really really low at near idle and I still can't get it leaned out enough.
Thanks.

What is your fuel pressure?
What size engine and cam is this? Turbo or supercharged?
What is your VE near idle?
What is your pulse width at idle?
What symptom and measurement do you have that its too rich at idle?
I'm sure you know this is a huge injector and even with the shortest command pulse width it might still be very rich.
Hopefully someone with similar sized injectors and offer some guidance.

Have you tried dropping fuel pressure just to see if that leans it out a bit?
You may need a manifold referenced regulator thats adjustable so at low rpm you can pull fuel.
Cause yea those are BIG

GM 12594512 5.3 Flex fuel injectors.
These are 36 lb/hr and were in the TBSS intake I purchased.
Mostly used with the E38, but found a P59 Silverado 5.3 Flex Fuel tune using these.
Tune file attached.
The P59 is nearly identical to the P01, so the data is there. Only extra you have to do is copy the Default Pulse table to the Min Pulse table as the P59 doesn't' have Min Pulse.
Also, a handy way to find vehicle usage for GM injectors is: https://www.gmpartsstore.com/
Enter the part number and it will show which vehicles to go look up in the HPT repository.

1500 SEP DEKA LONG Injector data Figure id contribute. hopefully someone can interpreted these a little better than i can.
looks like SEP is posting their injector data on their website.
I pulled their 1500 Long deka injector data and plugged them into my tune. helped with cleaning up my initial start up so i can actually start tuning my VE table.
