Short Pulse Adder does not change with fuel pressure/vacuum so if it's already been converted to Gen 3 format then it stays the same. Otherwise, use the old 'LS1 to LS3 injectors.xls' spreadsheet, only for the SPA table. That spreadsheet only works on the early Gen 4 data with 128-640 kPa Delta labels in the Flow Rate & Offset tables, but the SPA format is the same for both early/late Gen 4s.

Very very appreciated, I'll go and do some practicing

Looking for 1294512 injector data to put in my 02 P01 ecm. guess i need conversion as well. thanks in advance

If you meant 12594512, then those are already converted and already in my sheet. If you need a one-off conversion for something other than 58 PSI/returnless or 58 PSI/referenced you have to say what you have and then ask for it.

--->>>>>GM Gen4 injectors converted to Gen3 format for P01-P59 PCMs.xls<<<<<---

All these are in there, for both fuel system types.
19421333 - 29lb, various non-flex Gen4 trucks (alt# 12580681)
12587269 - 33lb, LY6/L76
12569113 - 33lb, car LS2 (alt# 89017586)
12594512 - 36lb, LMG/LC9 '07-'09
12613411 - 38lb, LMG/LC9 '10-up
12576341 - 42lb, LS3
12609749 - 50lb, L92/L94
12613412 - 51lb, L96
12598646 - 52lb, LSA/LS9

You're welcome in advance.

Great, thanks!

anyone having problems finding the data for the various injectors in google sheets, the tabs are across the bottom of your screen

Green Giant 42lb (50.29lb@4bar) - Bosch 0280155968 - FIC data.

Under the Short Pulse Correction area, I see two tables, one is obviously the adder , but i'm not sure I understand the other table as it shows Pulsewidth vs ms but in Gen3 P01 PCM its listed as Pulsewidth vs RPM. Does the min inj pulsewidth need to be changed? I see where it says to leave the default injector pulse as stock value so I did. Im asking about the min inj pulse.
Thanks!

One version is for Gen 3 which has 67 or whatever columns. The other is for everything else (Gen 4) that has the much much smaller SPA table with 33 columns.

As with every other table in a 'universal' datasheet, use the one that matches the labels/format/shape/size in your tune file.

Right thank you.
I don't like to assume but, since I'm using the Green Giant injectors with P01 I assumed the Min Inj PulseWidth data table is supposed to be updated as well based on comparisons to other data to other injector data. It is supposed to be changed correct? If so, what is the data supposed to be? Thanks!

It does say "USE STOCK VALUES FOR SHORT PULSE LIMIT,AND MINIMUM DEFAULT PW". Different ECM families/versions use different terminology for essentially the same tables.

Yes, and i did leave the stock values which i highlighted in yellow. I have attached a picture of what i'm talking about.Fuel_snip.PNG

12609749 - 50lb... I've seen else where they are 54lb and I just put them on my deleted camed l77 with flotek ported heads... fuel data? So I can get it close before going to the dyno

[Hotfuzz_caprice]

Add for some reason it won't let me open previous posted links you've sent out squirrel
