Quick question, is there a Forscan test I can run to determine if my injectors are single shot vs split shot?
Thanks

 

Does your truck have a tuning devise on it? knowing what tune(s) are being run may be the easiest way to determine the injector size

 

It has a Hydra, was there when I purchased a few years ago. My cheat sheet says the highest tune is +120 mph.

 

If you hook it up to computer with hydra flash software you should be able to see which tunes are loaded into it to see if there for single shot injectors or factory injectors.

 

can you post a picture of this cheat sheet, if it is a printoff from the hyrdaflash software when the tunes were loaded?

 

It's handwritten. Does the ECM need removal to unplug the Hydra?

Appreciate your help...​​​​​​​

 

Does the Hydra have the programming cable on it, or ws it stuck on without? If it is on, it is easy, just plug it in and open up the Hydraflash program and see whats on the chip,
If the programming cable is not in place, then you will have to remove the Hydra from the pcm. Best way to do this will depend on how the pcm case was cut, some cut enough out so the Hydra can be slid on and off with the pcm in place, some do not and the pcm will need to be removed and the case slid off.
Here is a link to Hydra help, it has some good info, and install/program videos that will like give you a good visual and be helpful.

Hopefully the easy way!! Thanks

 

Quick answer.
No.

 

Unfortunately, no programming cable and the pcm will need removing. Pretty much always the hard way for me and this truck.

 

there should be a hole in the cover that the chip slides right out of. just make sure there are no keys in the ignition.
if they were healthy injectors it would be easy. in my truck i have hybrids, you remove the chip and it idles like crap

why is it so important to know if you have single vs split?

 

Unfortunately hole is not big enough. Not that important, just want to know of they're stock.

 

interesting.
How do you feel the truck performs in comparison to what you think a stock truck feels like.
does it blow a lot of black smoke if you get on it, does it get up and go, I guess that depends on your elevation as well.

I think there are other ways to determine. Is everything stock under the hood. If there are not any upgrades, then most likely they are just stock. If you put the hydra in 00 it will bypass the chip and run off stock pcm programming (in theory, i've never tried) but it should be the same as unpluggin it.

however and possibly unlikely, there are smaller injectors that would be similar to stock but upgraded IIRC.

To me, my guess would be stock injectors with PHP tunes. If you notice an aftermarket HPOP, fuel upgrades, etc, then it could have bigger injectors. Also, I don't know how your truck runs or gets up and goes, etc.

Also, while a bit of a pain, it's relatively easy to pull the computer to get proper access to the chip. Should only take 15 minutes or so.
This way you can hook it up to the hydra software and see exactly what's on it

another possibility but not entirely accurate would be how much boost you can make. stock injectors with stock turbo on a chip can only produce so much boost.
Here in Colorado a totally stock truck can only make around 15 lbs of boost iirc. on your 120 tune, here it would only make like 25 lbs of boost iirc

 

He can pull the chip and connect to Hydraflash to see what tunes are on it. The naming convention of the tunes should give a pretty good indicator of the injector size.

Tango, maybe get an extension cable to install while it’s out. Then in the future you can hook the laptop up while the chip is still installed. Pretty handy option and doesn’t cost that much. Makes swapping tunes a breeze.

 

I realize this but he seems to be dreading taking the computer out for whatever reason.

I personally think he should enlarge the hole on the plastic cover to be able to easily remove the chip if need be. He could also hook up an extension cable as you mentioned. I just prefer to pull the chip out whenever I reprogram (which is not very often).
whatever one wants to do.
