Correct IFR tables for LS3/LS7 injectors in Gen III

[redhardsupra]

yes, but that's just some math tricks away, not a real problem.

I dont have the ability to do that math. What would it cost to get the correct data???

If I cant get it, I can get a set of FAST 36lb injectors for a decent price that I think are Bosch or Delphi. And at my 58psi fuel pressure they shoudl be around 42lb/hr which would work just fine.

Does the increased fuel pressure change the values of everything?? I would think with more pressure on the pintle the short time would change the amount of time it takes to open and start flowing fuel.

I believe the "F.A.S.T 36lb injectors" are actually the Bosch 0280155868
If you look at the bosch injector.pdf I linked to you will see they are
34.54lb @ 3bar & 39.88 @ 4bar

With so much conflicting information on just about every injector advertised,
it seems like no one really knows what any injector flows.

Like i said lets see what joe comes up with...

SweetS10V8,

im glad we have people like u here, as well as marcin, thanks for sharing what u found...

It's done, I have a generic program of interpolating (linear, spline, or cubic) any functions, 2d or 3d. I tried to make some pictures of the original and interpolated surfaces, but they're close enough they just mess up the charts. So which particular data do you want me to convert? Give me a list and i'll just make a simple spreadsheet out of it so people can look it up without much issues.



MATH-PANZIES!

marcin,

all we wanna do is interperate ls/7/9 injectors into an ls1 pcm.. we need a simple spreadsheet that will do that....

i would like to see 2 seperate sheets one for ls7 and one for ls9 since the tables between the two differ slightly

send me two spreadsheets then, one with data for LS7 and one for LS9, and I will 'fill in the blanks' for you. marcinpohl@gmail.com is the address.

[WHYTRYZ06]

marcin the tables that we would need to change in the ls1 pcm are....

B3701- injector pulsewidth voltage
B4001- injector flow rate
B4003- minimum injector puslewidth
B4005- small pulse adjust

corospond those tables w/ the ls7 and ls9 calabration....

thats what we need...

joe is working on the ls9 for me, so we will see what he comes up with...

im terrible with math so any help would be nice

marcin,

id love to, but i have no idea how to use excel.... im a total dummy when it comes to this stuff... all i know how to do is plug in the numbers and what ever it spits out i put into my tune... :(

im a wrench, i also tune my own car.... but this techicnal stuff stumps me...lol i even went to OLSD to simplify my tuning...

oh dear, i do now what tables we need, i've been around this block a few times. what i don't have is the stock values. put them in the appropriately named spread sheet. send them to me. await answers. receive correct values. offer the gratitude of your younger sister.
