I believe I found the correct data on my injectors, but I am not certain it's correct. They came from Mass flow, with the entire kit. A9L eec iv, Edelbrock single plain intake with injector bunges welded in. Throttle body that looks like a carb, with Corvette Mass flow and a converter to voltage. MassFlow said they are 36 lb/hr injectors. The information I found says 42 lb/hr, but I believe that is rated at 45 psi fuel pressure, where Ford used 39 psi. I plan to use 45 psi fuel pressure.

I have changed out to a mass flow meter that, I think dicephia, recommend to me in 2014. I replaced the MassFlow air filter and mass meter with a fairly long pipe, to smooth out the reversion air flow from the cam.

Basically I started this in 2014 and it has sat unfinished since. My wife had health issues. Then my employer sold the business, and I was working and traveling all the time. Then I had to have a liver transplant followed by a kidney transplant. Now I am retired and back to good health. So I am just now getting back to finishing this. The biggest problem is that I have forgotten a lot.

Finally back to my question. Since I am not certain about my injectors and I have never ran the engine with the new mass flow sensor setup, I am thinking it would be best to put everything into an A9L bin. Run the engine and get the fuel sorted out. Then once I have it running decent at light to medium loads, put all that information into A9L2 and start turning. Does this sound like a reasonable place to start?

no thats a horrible idea

a9l requires significant changes to dial in a bone stocker

is your injector data not on the homepage ?

what are the part numbers on your injectors ?

There is a number near the plastic part of the injector beside the electric plug. The Number is 01D114B. I searched and searched back in 2012. On Racetronic website I found item code 01D114X. It is a 37 lb/hr injector. The website data says 12.2 ohm. my injectors measure 12.0 to 12.1 cold. I believe it is my injector, but I'm not certain. Racetronix also listed the actual manufacturer as Standard Motor Products.

This is what I saved off of their website:

Description
01D114x ( INJL37)

TECHNICAL INFORMATION

Injector flow rates are based on testing with n-Heptane test solvent (0.6855 g/ml). U.S. EPA emission test gasoline 40CFR86.113 (0.735g/ml) flows in most common injector designs at about a 3 to 4% higher rate than n-Heptane. A ratio of 1.035:1 can be used when converting the flow specifications above.

This high-impedance injector will work with all factory ECM/PCM injector drivers.


ADDITIONAL INFORMATION
Top feed disc injectors uses multiple holes around its circumference. The disc rests on a short chimney that surrounds a metering hole. As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.
Performance advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as listed by Delphi:
• The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur.
• Compatible with alternative fuels (i.e. E85, Methanol)
• Longer service life
• High-speed disc action allows wider dynamic flow range for improved idling
• Quieter operation
• Revolutionary disc design resists build up deposits which can affect fuel flow.
• No Fuel leakage for quicker starts
• Grease supplied to lubricate o-rings prior to installation

I also found information that 01D114B is actually an accel 150140. This is the information that I saved on it.

So I just used Copilot (an AI search engine). I put in the 01D114B fuel injector and it gave me stuff that didn't make sense. So I then explained the MassFlow system. It came back with (short version):

Siemens-Deka EV1 injector 36 lb/hr @ 39 psi
They flow 38lb/hr @ 43.5 psi

Copilot said for 43.5 psi and an A9L2 use this data:
FN367 High Slope 38.00
FN1360 Low Slope 43.20
FN389 Breakpoint (lb/inj) 0.000028
FN367A Injector Offset vs Battery Voltage
voltage row (V): 15.94, 15.00, 14.00, 13.00, 12.00, 11.00, 10.00
offset row (ms): 0.48, 0.52, 0.60, 0.72, 0.86, 1.05, 1.32

Bottom line: Copilot gives amazingly good information with great confidence. It equally gives absolutely wrong information with the same great confidence. It took me down the wrong road troubleshooting my Lincoln plug in hybrid. I spent over $300 on parts that were good. Then blew a fuse block that is located above the lithium battery that had to be removed. Dealership charged $2700 to fix it. Had I went to the dealer first, it would have been $900. So do I trust Copilot? Maybe. This looks reasonable. I ask you opinion. Trust this Data?

prolly good as any, seems to be in the ballpark compared to the others published data

Thanks!

I have downloaded the latest TunerPro, A9L2 bin, and the other two files. As I have said, I have forgotten most of this stuff, so I am sure I will have more questions.

The battery voltage offset is quite a bit different between the Accell and Siemens data. However I have always doubted that my injectors were made by Accel.

those values you posted are pretty reasonable compared to the other published data on the homepage for the other injectors in that line up.

comparing it to siemens is pretty useless as those are definitely not siemens injectors.
