42lb injector data

[redtail2426]

does anyone have the correct injector data for 42lb green top fords??
I have the ifr table from redhardsupra from like 6 years ago,and upon searching found it may be incorrect,but i cant find the new data anywhere?Im not buying a cd for 250 either,any help would be great

Part number from the injector?

Part number from the injector?

the data is converted for GM usage. ford data is wrong when the injectors are in a chevrolet.

[Throttle]

they are 52# in a chevy ,fords are only rated at 38.5 psi i think

Looking for the part number to help the op. We know flow changes with pressure. Thanks.

If the injectors are Bosch greenies that end in 968 I couldn't find 4 bar pressure data but worked the tables from 3 bar and got it very close. VE and MAF came right in on an injector swap from 868's.

The 968's are closer to 50 lb/hr at 4 bar or 58 psi IIRC.

[redtail2426]

okay looks like they are bosch #280 150 558

From the Bosch website these are 326.8 g/min @ 3 bar pressure.
Conversion makes that 43.22827563 lb/hr@ 3 bar.

You run at 4 bar I presume (58 psi). The spreadsheet I found calculates the following results. (see below)

While it may not be perfect, it should give you a fair starting point, at least it did for me on a different set of Bosch 42's. I hope this helps you get started. Not likely any one here will share the actual injector data.

I'll share what I have... I think it's BS that others won't

And I got that info from building a table off of this info:

[redtail2426]

hey thanks a lot, Now thats a nice guy there thats willing to help someone out.Im not sure why there are so many people that want others to pay for some info that should be easy to obtain.If i had all the info,i would post it for people to see.Heck i let people borrow my tuning equipment at no charge to make some changes to there cars,if im not using it at the time,sure take it.Im not sure why people are the way they are.But there are still good people out there who will go out of there way to help someone out.I appreciate it.

Prior to Greg releasing his $250 DVD people on this board helped with injector info. Now it's a ghost town.

I'm sure if you ask someone will give it to you.

From the Bosch website these are 326.8 g/min @ 3 bar pressure.
Conversion makes that 43.22827563 lb/hr@ 3 bar.

You run at 4 bar I presume (58 psi). The spreadsheet I found calculates the following results. (see below)

While it may not be perfect, it should give you a fair starting point, at least it did for me on a different set of Bosch 42's. I hope this helps you get started. Not likely any one here will share the actual injector data.

what are u using for this?program/webpage/application etc...

[Iam Broke]

Excel spreadsheet I found. Compared the data it generated for my stock 28 lb/hr injectors vs. stock inj data and it was close. Never claimed it was perfect.

See attached bosch inj pdf and injector.xls

[LSxpwrdZ]

Even the converted Ford stuff is only 2D. GM's characterization of an injector is SO much more precise than Fords is. Ford defines the short pulse data using a slope. GM uses a table for specific pulsewidths to alter fueling +/- based on how the injector flows at that pulsewidth. It would take nearly a full week of testing to characterize an injector for all the points in the GM tune file. I am currently trying to get parts together to do this because I'm tired of nice car's coming in with FAST, Bosch, Delphi etc injectors with nothing more than the general flow rate. This way I can pull the injectors and test them physically and truly get calibrations accurate instead of some jacked up data from a Ford or someone else on the net.

[QUOTE=waynehartwig;293928]I'll share what I have... I think it's BS that others won't

Everything is top secret...sshhhhhh There are a few that will help you though.

AS long as this board has been up. If more were shared it would be a killer knowledge base by now. There is good info here but some not so easily found. Some just wrong and screwed so its hard to tell what to go by sometimes unless some of the sr tuners reply.

If any tune is actually posted its one that is really hurting like the ones I posted here a while back...lol.

For instance...
Many have the greentop injectors however there are very few files uploaded for anyone to compare to.
