I had some down time last night that I got to use constructively...using the origonal spreadsheet made by an unknown author(thank you whomever you are) I modified it to work with not only LS1's, but all GTO's, all cobalt SS's, and many if not most late model ie 97+ GM V6's.

Have fun.

very nice....

 

yes it is.

 

the sheet uses Injector Flow (g/sec) but hp tuners uses lb/hr how do you translate between the two

 

hptuners just DEFAULTS to g/sec...just change the table to lb/hr by right clicking on one of the cells-go to units & change it.

 

Have any of yall tried it yet ?

Here what it looks like in HP tuners

 

eck...i think I copied the wrong one over for you guys...I'll get it fixed asap.

should be fixed now, same link.

 

umm that doesnt look right , the other one looked and alot better and worked really well i put the values tht last sheet had and it worked really nice.

 

i just redownloaded & set it up with some 60lbers & it worked fine. So I dunno whats up...worked for me.

 

i dont know what numbers where there before but i used what ever they where i have the hp tuners out out for both if you do it in reverse. but i did put it in my comouter and for the most part it work great !!! alot faster then the flow i had before.

when i put 60 in the injector flow rate here what i get

7.698272057 7.780348516 7.861568126 7.955276372 8.034727906 8.113401438 8.191319384 8.281297122 8.357649932 8.433311494 8.508300249 8.594960261 8.668550758 8.741521756 8.813888641 8.897572801 8.968680623 9.039229086 9.109231188 9.190226418 9.259086995 9.327439217 9.406555751 9.47384407 9.54065783 9.607006933 9.683839681 9.749214396 9.814153641 9.878666006 9.953401972 10.01701758 10.08023172


All those 8.00 and up max the injectors at like 64.39 so tell me what u get when u put that stuff in

 

6.324775889 6.392208581 6.4589373 6.53592648 6.601202576 6.665839478 6.729855604 6.803779859 6.866510093 6.92867241 6.990281958 7.061480423 7.121941187 7.181892979 7.241348442 7.310101995 7.368523032 7.42648451 7.483997105 7.550541476 7.607116213 7.663273294 7.72827416 7.783557155 7.838450261 7.892961611 7.956086155 8.009796964 8.063149998 8.116152315 8.177554176 8.229819731 8.281755448

thats with
58
58
60

entered into the sheet

if you've got injectors that are larger than 60lbers then yes you will max them out earlier.

The numbers you listed leads me to believe your using ~70lb injectors which is well over the table max.

 

no were all good now i had the injector rated fuel pressure at 39.15 , with Your Fuel Rail Pressure: set at 58 and Injector Rated Flow Rate set at 60 but when i did it your way

58
58
60

it looks alot better Thanks your the best

 

I can't change any of the values in the spread sheet. Do I need a different program to run it?
Thanks,Chris.

This should be stickied

 

I think doug EC_Tune is working on another version of it that has it converted to imperial for you guys...once its done I'll post that one as well.

 

Nice! Thanks!

 

Just what I needed (I think) Siemens 60lbs sitting on shelf. waiting for pulley selection and HPTuners. gotta order.

Is the fuel pressure supposed to be 58? I thought and believe so I am just confirming.

thanks

 

Bringing back a dead thread to life i looked at the GM spec page and its not 58 it is 56 here is the link
