well that makes me feel a hell of a lot better knowing your running a 383 with lightly ported heads on 24's good deal boss ty

Ford put out the calibration sheet on them. No reason to trial and error it(unless you don't know about the calibration sheet), you calculate them.

Get the part number off the side of the injector and search that part number plus "voltage offset" on Google. Should give you a sheet on one of the results. Or post up the part number and I'll see if I can find em.

ACE1252

It's not quite that straight forward....unless someone has done the work and posted it up(as I have on the fat red top Ford 30# injectors). You generally will not find the direct information from a google search. I certainly didn't when I was looking.

You get the calibration sheet and then have to do some interpolation calculations based upon the pressure you plan to run.

I do think the voltage offsets were a little easier to get to than the short pulse adders.

hrcslam

True. The voltage offsets available don't cover every cell in the tune, so math will be needed to fill in the blanks.

Has anyone tried the Ford blue 24# injectors as less problematic stock replacements? The ones that came on the 32V motors?

Justin96z28

With EV1 connectors. They are BOSCH injectors with the 4 pintle hole spray head. I am running them now, and need to be tuned for them even though they are 24lb like people were stating above they really are a 25.xx in our motors its weird plus the spray times differ on them

Part of that may be due to the fact that they're rated at 39psi vs 43.5 on the LT1. I have an adjustable regulator on mine, but if the lag time is far enough off that may still be an issue. I'll see if I can dig up a stock tune for one, hopefully on the same software that works on my car. I'm going to get a chip burned to remove EGR and stuff anyway, so if it's copy/paste I doubt the tuner will ding me for it.

Justin96z28

Yea thats where I am at right now I need to find the lag times for these things. Besides redoing my opti yet again lol

hrcslam

Did you find the part number for the injectors (it should be stamped on the side of the injector)?

Justin96z28

24lbs on one side tre on the other... Waiting for a reply back from them about spray times and specs

Justin96z28

This is the email I got back from the company I got the injectors from..


Hello,

The lag time is 1.2ms at 14v, we do not have complete off set tables, it
is not a cheap process to get that for all injectors we sell. You can
extrapolate for other voltages based on the 1.2ms at 14v in comparison
with other injectors. The key thing is to not run a pulse width less
than 3ms because we have no way to test on our ASNU machine for lower
pulse width.



Thank You,
TREperformance


My question is, aren't our injectors running on a 12v system?

With engine running, alternator output keeps the system near 14V.

Justin96z28

found this table
http://www.carprogrammer.com/Z28/PCM.../injectors.htm

that svo 24 comparable to bosch 24s?

Justin96z28

Also would I use this excel file to figure out the scaling?

hrcslam

I thought the SVO were Bosch. Do you have the actual part number from off the side of the injector?

hrcslam

No this one is for something else.

I believe you're right.....but Bosch manufactured the SVO's to Ford's higher and more precise specifications.

You can kind of look at it like this:
Bosch = Chevy
SVO = Cadillac

And don't you all get your panties in a bunch.....you all know that Cadillacs are better .......LOL!

Justin96z28

LOL.. These just say 24lbs on the side of em
