i do not totally understand about the IFR table. Okay the injector table in excel that I posted deals with your ACTUAL FUEL pressure and your injectors rating. Well, if the actual fuel pressure is 56psi but the current tune is for 43.5 why do you leave it at 43.5???....lol It's just not making sense why to leave the fuel pressure at 43.5 when it is 56 or X say

so you are saying use 28.8lb/hr at 58psi from the excel sheet....or are you saying use 28.8# @ 43.5??
the stock table is 43.5psi @ 28.8#
the stock table is 43.5psi @ 28.8#

ok maybe this will help
the injectors are set to a flow rate from the manuf. of them. 2001-2002 are 28.8 lb/hr @ 4 bar (58.8 psi, 402.2 kpa, but its 58 psi for the sake of rating). this is the value that goes under WOT, zero vacuum in the ifr table. from there you have vacuum causing a larger pressure drop. so if you idle at 30 kap, that means you have 70 kpa of vacuum, that number gets added to the stock fuel pressure. so the stock fuel pressure is say 58 at idle, idle has about 10.5 psi of vacuum. so the flow rating entered in the table is actually for 68.5 psi rating at 70 kpa vacuum. larger pressure change means smaller opening for the same amount of fuel to flow through.
may have confused you but in the end a table set higher than stock will make you run leaner and give you tuning issues. the stock injectors are NOT rated at 43.5 so whoever told you this data is wrong.

look again, the stock table is set for 28.8 lb/hr @ 58 psi INJECTOR RATING. so the value at 0 vacuum, if you load the stock table in imperical will read right about 28.8 psi, i think it is really something like 28.91 but i cant remember. but if you enter it as 58.8 psi injector flow rated pressure you will get the same table if it is slightly off. the value at 0 kpa in the table is your injectors rated flowrate.

well i think we settled the ifr table 43.5 number. that is what the format is saved as for the rated pressure so he thought that was it and a while back there was some fighting on the actual rating.
put that table back to 58/58 for the pressures (or for the rail pressure you can measure it and enter those values in, remember the ifr table is 100-MAP value. so if you idle at 30 kpa, and see 57 psi of pressure in the fuel rail, enter 57 in the spread sheet at 70, not 30). then sd tune it and you will be on your way for sure. raise your pe enable map too so you can cover the ve table better, id put it to about 70-80 or so, it will still kick in WOT

Here ya go.
Stock IFR for 28.8 lbs injectors in an 01 ls1
You will probably have to convert for imperical, since you are using EFI live...Then again they may have an option to change formatting as well. I know HPT does...Good luck.

got it figured out guys...thanks. Ok I'm NOW IN SD MODE !!!! YAY!!!
Now also when I booted up flashscan I got some DTC codes...MAF stuff..but I did turn off everything according to the write up TAquickness did I have two yellow DTC maf codes and then two red DTC maf codes on the obd screen (f7)
did it just now and made two logs for the BEN factor. Now I'm quite confused as how to hide values less than 50 though..??
also when I didn't hide those less than 50 and copied the BEN table and pasted it as "factor" to the VE table it gave it a lot of chops...So i didn't even bother tuning that...figured something was wrong.

also with it throwing these DTC codes...could I get inspected and pass?? or even with them cleared and the codes not there would it be ok? (kinda guess it would then)
so what tables am i missing....lolits p0102..what value do i put for that??

I just read your post on live - I'm not very clear about what you are asking. The write up I sent you is a step by step...
Pasting as a factor is just that. right click, paste as factor
What do you mean by chop?

not chop...don';t know where that came from.
When i paste the actual numbers as a factor into my VE table I get some weird numbers...I sent you a PM.
ok well I updated to the pre-release, it worked!!
but the hide cells seems to only hide empty cells..maybe..
and when I do copy and "paste as factor" to the VE table I get some funny numbers.. like for instance at 2400rpm at 15kPa I get 143.9
2800rpm @35kPa I get 190.8
and 2400rpm @ 75kPa I get 235.2
these can't be right?? I was copying the actual averages not the cell counts. And to say my averages are around 2.4 and 2.39 and then up at high kPa around 2.7
