Hi
Need advice from experienced people on EBL tuning. Do to things, haven't played with EBL in 4 years.
My TPI is in an 83 Monte with a 2004R and a 3.73 rear.
I have selected a bin that "matches" my engine combo which is a 3001.BIN
I have 22lb injectors, aluminium heads and a mild cam.
From a dead stop can't/won't break the tires loose. It's like I don't have bottom end torque.
Highway speed is great.
So what do I look at to start?
Thanks

Was wondering if the EBL has the Port Mod. If so changes are required to the 3001 BIN due to this.

As for off a dead stop, the torque converter (TC) stall is important. Need to get the engine up into the power band before the converter starts to couple.

To help with loading the engine against the TC there is the launch mode (LM) feature. This can be used to add spark advance on tip-in from a stop.

There are mechanical issues that will affect engine power. Having the base distributor setting matching the BIN Initial SA is important. Matching damper and timing tab is important.

Valve adjustment, binding in the drivetrain are also considerations.

Thanks for your answer
When I did install the 3001 I don't remember if it has a port mod. Will have to reread the manual to see what it is and see if it was installed.
I'll also read again about the LM feature.
Base timing is set at 6* BTC. Engine mechanically is sound.
P.S.
Looked at the WUD at home and not hooked up to the car. I do see a box that could be checked for Launch. By the definition in the book it say's "Launch mode SA active".
Where do I look to see if this is correct?
Still don't see where I could find the "port mod" also.

The box on the WUD shows when LM is active.

Need to look at the BIN to see the LM parameters and how they are set.

As for the Port Mod, if you still have the receipt check it. Otherwise will need to pull the top cover off the ECM and check for the physical presence of the board. Or, if you purchased directly from US PM me your name and I'll look up what you purchased.

I bought it from you in 2012?
Bought it with the wiring, fuel pump ect.
I'll send you a PM with my info.

Thank you for the PM, with that everything changes. You have the EBL P4 Flash system which is a port injection ECM (can also do one 1-bbl TBI). So no need for the Port Mod.

As for the 3001 BIN, it is part of the low power issue. That BIN is for a L05 swirl port headed 350. Just not enough spark advance (SA) to make power with the aluminum heads.

Program two banks, each with one of these (use different banks then the current one):

EBL_F_P4.BIN
EBL_P4_3005.BIN

Take each for a drive, data log each, and see how they are. Note that you can switch between them with or w/o the engine running. Just need key-on.

Went to where my car is, it's not where I live.
Very confused. Don't even know what I have as a Bin. Tried to look for it in WUD and Tuner Pro.
You want me to put in:
EBL_F_P4.BIN
EBL_P4_3005.BIN
Honestly I don't know where to start with this.
What page in the manual can help me with it?
I selected the scalards menu to change the value of the LM period LM/SA to zero seconds. I now can't get back to the original roster of the three items that are listed on the left of that page.
Hope this makes sense.

The location of the BINs is not documented because it can't be. During the install the user can place them wherever they want. The default location is:

C:\Program Files\Dynamic EFI\EBL P4 Flash\User_Calibrations

There may be an "(x86)" at the end of the Program Files folder name: C:\Program Files (x86)

The easiest way to find the BINs is to open the EBL P4 Flash Program Group and select the User Calibrations entry. That will open a Windows Explorer dialog, go up one level and click on the "Calibrations" folder to open it.

Click on the little - sign at the top of the scalars list.

Thanks
I sat at home and started the WUD and Tuner Pro to get familiar again with it.
Found the 2 Bins already in Tuner Pro files. When I first got EBL must have used them.
In WUD used the display button and opened bank select.
The next step that I see is to connect with the ECM so I can reinstall the to Bin files that you want me to have in bank 0 and 1.
I did try data log because I named EBL_F_P4, 17 times.
Back then I didn't take notes, which is my mistake.
I did find how to get out of the scalars list also.
I know the manual explains all this but I'm the type that works well with a list, as in, do step 1 now do step 2, ect.
Or pictures of what has to be done.
Will have to go to the car and see if I can install Bins in the banks.
Is there a way the WUD can be made bigger? The display is about half size vs the main screen of my laptop.

Was at the car today my learning curve is better.
I can program bank 1 and 2 but I can't toggle between the two. If bank 1 is programmed it's also in 2 and the same for the other Bin if I do that.

Found that selecting "File" on top of WUD gave me a drop down menu so I could select a VE learn. Stayed with the 3005 Bin and ran one at idle and about 1200 RPM at operating temp. I have an idle/off idle stability problem and thought this would help. I also went into File/Preferences and changed the VE smoothing to 20. Ran this learn for 45 minutes.

I am running Bosch 3 injectors at 40lbs with vacuum to the regulator and have read on the forum they do run rich and to limit the voltage to them. Where do I find this setting in scalars?

Also noticed being that my base timing is 6* BTDC and set properly, the dynamic timing is 20* at idle. Would you say this is normal?

Set the PromID is each BIN to a different value. Then when you switch between the banks that will change on the WUD. The bank switch dialog:

ALT+D -> B

No such thing. Setting the injector flow in the BIN properly and running VE Learns will take care of it.

That is OK.

Not at this time, some laptops have a screen enlarger, can also reduce the display resolution.

This was your answer to someone on the forum about Bosch 3 injectors:

Re: Bosch design III PW offset tables
The type III injectors flow more fuel at small PWs then at larger PWs. Because of this it is best to zero out the low PW offset table. As that table can only add to the injector PW at 3.9 mSec and less.

As for the voltage offset table, what fuel pressure (vac line off) are you using?

RBob.

I thought that would change the voltage to the injectors.

RBob

iTrader: (1)

The offset compensation table changes the injector PW relative to the vehicle voltage. This is due to the injectors opening slower when the vehicle voltage is lower. And opening faster with higher vehicle voltage.

RBob.

83 Gman

So is this the way to go with these injectors?

'Because of this it is best to zero out the low PW offset table"

RBob

iTrader: (1)

Should zero the low PW tables as the data provided by Ford is different from how GM did the offset compensations.

RBob.

83 Gman

So just leave it alone?

RBob

iTrader: (1)

The low or short PW table should be zeroed.

The offset compensation table should be filled in with the proper values.

Note that this is for injectors that are using the Ford data for the compensations.

RBob.

This is where I'm confused with your advice.
I have these injectors bought from this vendor:

https://www.southbayfuelinjectors.co...amaro-firebird

The way I understand it if it's a Ford injector do everything listed. Or just do the "low or short PW table should be zeroed." using GM injectors?

The other thing you would like me to do is with programming the banks.
You want me to give the Bin a new number.

"Set the PromID is each BIN to a different value. Then when you switch between the banks that will change on the WUD. The bank switch dialog:

ALT+D -> B"

I have the
EBL_F_P4.BIN at 17
EBL_P4_3005.BIN this has no number after it yet

Is this what you are asking me to do? Or is a value different than adding a number after the Bin when you data log?

RBob

iTrader: (1)

When using injector compensation data from GM, both tables get populated with the GM data.

When using injector compensation data from Ford, the short PW table gets zeroed. And the offset versus voltage gets filled in with the Ford compensation data.

The PromID is a parameter in the BIN. Open the BIN in TunerPro and it is the first entry under scalars. that value is reported to the WUD for it to display. Look at the upper left corner of data on the WUD displays. It shows the current PromID.

Thanks for your answers and understanding of my lack of knowledge programming the system.
