95 Mustang Gt Cbaza - J4J1 Strategy Question

[JOESTANGMAN2024]

Hi Folks new member here just got my 95 Mustang GT back on road after 10 years of storage. Using Tweecer and hoping to get this thing dialed in i have changed the the typical Scalar settings and working on my fuel and running into some issues hoping some of you can help. My Mods are in my signature and i am trying to maximize performance. I have attached my recent tune and datalog upto 4000 rpm to get a base fuel map. No functions other than loading my Pmas Maf Curve calibrated to 19lb injectors with Ford 24Lb injectors no pressure regulator. I am wanting to get suggestions on my slopes where J4J1 has both high and low at 24 which i believe is not correct and set them at High 24 and Low 30. I have not been able to get my fuel dialed in above 2000 so hoping someone can glance at my tune and data log and give me some direction. You help is greatly appreciated looking forward to driving my car again.

caledit sucks for editing tunes and is notorious for corrupting stuff.

Best bet is to start fresh with a base tune using tunerpro and then just open the tune with caledit and write it to the tweecer.

What does no pressure regulator mean? Are you saying your using the stock regulator and not an adjustable?

If your maf is calibrated for 19lb injectors then that means it uses the stock maf transfer. Simply dial in the injectors and your good to go.

But, 24lb injectors at stock 40psi base fuel pressure is not going to be sufficient to supply the fuel demand of any healthy HCI 302 when properly tuned.

Hi Decipha thanks for the reply and yes i mean i do not have an adjustable Fuel pressure regulator and I am still using a stock regulator.
1. I have a BBK adjustable Regulator what pressure is ideal for 24 LB injectors
2. I also have an Older PRO M 75mm Maf calibrated for 24Lbs would this be better than the newer PMAS 75mm calibrated for 19Lbs
3. If i keep the 75mm PMAS -19lbs do i use the curve that came with it. They also have a spreadsheet to recurve this MAF for 24 Lbs confused here.
3. Is there a base Tune for Tuner Pro I am currently using the J4J1 strategy which strategy would be best for CBAZA and where is the Base Tune.

Sorry for all the questions I am still learning how to navigate this site I will Download Tuner Pro today.

Found the T4M2 strategy Bin File will try this file in Tuner Pro and Upload into the tweecer.
Is there a link to instructions on this conversion.

[decipha]

The strategy is CBAZA, t4m2 is the calibration file.

There is no conversion.

I am struggling with the T4M2 file as this is in a .Bin format and Caledit uses .ccf I dont want to mess anything up and need some direction.
1. I have installed TunerPro non RT
2. I have Opened FIle T4M2.bin
3. I have Selected T4M2.xdf

Does anyone know what i have to do next i do not see any export feature in the software. If there is a quick answer that would be great as i dig futher into resolving this issue.

[JOESTANGMAN2024]

Ok I opened the T4M2 file in Caledit and immedately noticed some considerable differences.
1. This file is showing an engine displacment of 472 vs 302 is this strategy based on a stroker motor build
2. Injector high slope is set to 30 will this work for 24Lb injectors
3. Egr System Type and Sensor type set to 2 I still have EGR so i can set this to 0 will do the same for Thermactor
4. I have all my emissions equipment installed so is there any thing else i should revert back in this strategy.
5. Nominal Air Fuel is set to 2048 from .9993
has Caledit recalculated these numbers or have i not opened the file correctly.

Read the Fuel write up where it talks about the K-constant. That will explain some things for you

[decipha]

As you've seen caledit uses .bin as well and can open it just fine and write it to the tweecer. The .ccf file is if you save any changes or anything with caledit which you should never do.

Correct, 30lb injector high slope and 472 cubic inches is the factory values for a stock 19lb 302 when you use the ecu's maximum resolution. This is due to the k-constant and is the principle of scaling.

After you read the fuel write up it will make perfect sense. Keep in mind that is just how caledit shows the values. That same tune opened in tunerpro will show the correct 19lb injector high slope and correct 302 cubes. Again this emphasizes the importance of using tunerpro to tune and only using caledit to write. FYI 302 / 472 = 0.639 * 30 == 19lb injector

If that's confusing you too much then its probably best you upgrade to a moates quarterhorse so everything makes perfect sense and you'd have far better logging and tuning abilities as well using tunerpro.
