I just got my ebl flash 2 ecm and have installed it. I have done some data logging. I am having troubles following the guide from dynamic EFI. I think I'm going to need someone to hold my hand until I learn how to walk.

 

So you have a mildly modified TBI system with a cam? Stock sized injector at stock pressure?

How does it run? What part of the setup do you need help with first? Have you driven it and done any VE learns?

GD

 

I have stock injectors and running increased fuel pressure. Not exactly sure what it is. I had the pressure regulator that was able to be made adjustable. The cam is stage 3, new Davis unified distributor, rebuilt stock heads, did away with the egr, throttle body spacer and pod spacer, ultimate tbi mods, dual 2 inch exhaust into a narrow x-pipe into glass packs. The block is balanced and blue printed. The truck runs ok. The tach is a little jumpy with cold start. It seems like it's just not as smooth running as it should be.
I have tuner pro rt. Am I supposed to run it or the ebl program. I did three data logs using the wud. I don't understand the part about selecting the bin files then saving them so they don't get overwritten.

 

TunerPro RT is for making changes to the tune. The WUD is for watching live data, diagnostics, data-logging, and doing VE learning, etc - the only changes it can make to the tune are via the VE learning - this only makes fueling changes and does not apply them but instead creates a new map that may be manually loaded through the "flash" screen of the WUD after you review the changes and approve of it's suggestions.

You should first set your fuel pressure to a known value so you can calculate your fuel injector sizing parameters and program those into the BIN.

The instructions are telling you to use a preconfigured BIN that comes with the EBL but save it to a different file name for your specific application in a different directory so you don't over-write the preconfigured BIN that comes with the EBL (in case you need to start over for example, or wish to reference what changes you have made).

GD

 

So is there only two preconfigured bin files? After I make a copy of the bin file to the user bin file do I have to import the bin into tuner pro?

Thanks for taking your time to help me out. I appreciate it very much.

 

The EBL Flash-II is supplied with 30-some base calibrations:

Start->All Programs->EBL Flash->List of BINs

No need to import the BIN, open it from the File menu.

Ok. So do I just randomly choose one of the bin files?

 

There is an included text document that lists the BIN files and what they are setup for.

But to properly set it up, you will need to know your fuel pressure.

GD

 

Any recommendations for a fuel pressure sensor that I can wire in to the ebl?

 

..... the EBL doesn't accept a fuel pressure signal. I mean it could.... through the wideband analog voltage input but that's not really neccessary.

You just need to measure the fuel pressure (with vacuum disconnected from the regulator) so you can calculate the Base Pulse Constant. You use the EBL_Utility program to calculate the BPC based on injector size and fuel pressure.

Read though this link on setup of the initial parameters:

The EBL systems can take up to eight 0 - 5V analog inputs.

We have been using Honey Well pressure sensors for fuel and otherwise. Getting one for TBI (0 - 50 psi) is problematic. Here is one part number to look for:

MLH050PGB06A

That is a 5V sensor (power), With a .5 (0 psi) to 4.5 V (50 psi) sensor output. Has a 1/8" male NPT pressure connection. Electrical is a common 3-wire Metri-Pak round/triangle connector.

It is also available with different connections (pressure and electrical).

RBob.

 

Oh yeah. Forgot about the general use inputs.

Still - you just need to measure the pressure with a shop gauge so you can setup the BPC values. For simplicity (initial tuning) just put it at stock pressure till you know for certain you need more than stock pressure will supply. I understand you can also use the BB injectors rather than increasing fuel pressure.

I feel stupid and slightly overwhelmed and out of my element. I become quickly lost when reading the help paiges. I'm not computer dumb but I also have no experience doing this kind of stuff. I try to look up the meanings of acronyms and other things I don't know only to run into more of the same. Before I know it I don't even remember what I was trying to understand in the first place and become frustrated.

As of right now I haven't changed a thing. In my opinion my truck ran better with the stock ecm.

I just want to feel like it was worth all the money and time I've spent on this truck. So far this feeling remains out of reach.

 

Open the List of BINs file and find the one that most closely matches the drivetrain. Find it in the BIN folder and flash it into the ECM. Start the engine and see how it is. Best to follow up with VE Learns.

As for the stage 3 cam, I have no idea what that is. So no suggestions on what to do there. Since you increased the fuel pressure need to get that value and use the EBL Utility to calculate the "BPC - BPC vs VAC" table of values.

RBob.

 

I will do that thank you.

As for a stage 3 cam it is referenced from Harris Tbi performance.

 

Short of taking it to a tuner (preferably with a Dyno), or scrapping the whole TBI system and either going full aftermarket injection or a carb, the EBL system is pretty much as easy as it gets. Just keep reading and you'll figure it out.

Tuning must be accomplished in some form. Be that carb jetting, dropping it off at the tuner's shop, or crawling through micro-code and burning chips..... there are all degrees of difficulty. The EBL system uses what you already had and
costs little more than a shiny new carb. No it's not a fancy-pants stand-alone injection system that tunes itself while you watch cartoons on it's touch screen display. But it also didn't cost $1200 - $4000 just to look at it in a box.

Cam specifications would be more helpful than this retailer's suggestion of what "stage" it is (subjective).

GD

 

So the cam came from Harris? I'm not seeing cams at a quick glance on their site.

If it dd not come from them, do you know what cam it is? What manufacturer, a model #, and / or any of the cam specs?

FYI...I'll need to get an EBL for my car too, so I follow these threads with great interest to learn as much as I can. I've read the EBL site page by page several times. I can eventually get to a point where I sort of understand what's going on. But I quickly forget all the acronyms when I'm not using them daily. Reading all that info through and through again and again is the only advice I can offer. I've followed threads where RBob and others have walked folks through these issues. Hang in there.

 

The cam didn't come from Harris just used his site as a guide. My cam is made by sealed power 1800-5000 RPM Range 283 intake/286 exhaust Adv Dur Duration @.050 209 intake/216 exhaust Valve Lift .435intake/.455 exhaust Lobe C/L 112

 

Those are the number the boys will need!

 

has anyone put together a good YouTube walk thru for ebl?

seems like that would answer most questions much easier.

 

There are several pages of information on the Dynamic EFI website:

https://www.dynamicefi.com/Tune_Intro.php

https://www.dynamicefi.com/Tune_Intro2.php

And these come with the unit on a CD as well. As well as references for all the tables, scalars, flags, ets.

GD

 

so sorry. Can we walk through the Tuner Pro step again?

 

I feel like I’d be in the same boat and that’s why I’m gonna get this running on a stock TBI setup in my truck before working on the tune a bit.
Then make a few upgrades and re-tuning for those before adding a TPI intake system and new heads.
Finally a cam swap.
I feel like these steps will simplify the tuning process and by the time I get to the cam swap I’ll be more comfortable with the timing process
