EBL worth it?

[907 Chevy]

I pulled into the parking lot at work last week and my engine just shut off. Now I have a rapidly flashing cel and the engine just cranks while making no attempt to start. I'm going to swap in a known good pcm to see if that's the problem and if it is,that leads me to my question...

Should I just find a junkyard pcm and keep burning chips or should I shell out the $400+ for the ebl?

I have no electronic transmission to worry about,as I've swapped in a manual and the flash programming capabilities of the ebl would be a big improvement over burning endless iterations of eproms,but do the other added features of the ebl make it worthy of its price tag?

What're your guys' opinion of the system?

[randeez]

do it

[ngneer]

Have it, like it. Went through the chip burning process, got burned out on the whole process, datalog,edit, datalog etc. With EBL, drive, pull over, edit, and see the changes immediately. Still need a wb 02 to get to the final tune, not near the hassle.

The 454 SS guys are doing a group buy in Mar if your interested. IMO it's the best thing you can do for a TBI truck, besides heads, cam, and a whipple, but then you need the EBL

my truck is a 95 and it came with the 7427 pcm. is the EBL worth the swap for my truck?

Someone will correct me if I'm wrong (believe me they will) but I don't think EBL will control the 4l60e which you have. EBL works for pre 1993 vehicles IIRC

You may be correct on that one. I don't think the ebl is capable of controlling an electronic transmission.

I'm pretty much sold on getting the ebl,although I'm wondering about some of the mechanical aspects of the swap into a 93-95 truck. Obviously I'll need to repin the harness,but I'm guessing the harness connectors themselves will need to be changed?

Not really an issue at all,I'd just like to know for sure so I can start gathering whatever parts may be needed for the swap ahead of time.

EBL is excellent, so is all tech support from Dynamic EFI. Just send RBob and email and ask?

Just sent him an email with some questions on the swap a couple hours ago actually. I'll post up the answers when I have them...

Anybody that's read the threads I've posted in should know my vote I think it's great. I never did the chip burning thing, a little before my 'time' far as tuning goes. I also think it's great because it doesn't require a completely new harness to run it, it uses what's already there. An EBL won't control an electronic trans, not that there aren't other options for running an EBL with an electronic trans. I posted in the long EBL thread on TGO about a standalone controller a while back, and Bob said something along the lines of "it's in the works". He also has an SFI controller available for the turbo v6 engines.

I'm thinking I'll also run one in my Malibu. Certain G-Bodies came with 4.3 TBI engines, so I can basically run an OE EFI setup, at least up to the engine... this I like since I can order OE fuel lines and run a stock style in-tank pump. The engine will probably have a TPI setup, but I'm thinking port injection for sure.

I've been meaning to ask this for a few days but keep forgetting. Theoretically speaking, could you buy the EBL, tune the motor til it's spot on and copy/paste that tune to a chip with a 93-95 ecm? The chip would have the ebl tune and still be able to have the tranny controls in it. Then you would have an ebl you don't need lying around but it seems like a great idea to me. Even more so you could tune many rides with EBL and simply burn and sell a few chips to get your investment back.

I didn't think about the last part ahead of time....it just came to me while I was typing

One thing worth considering is that the code itself that runs on the EBL is more sophisticated by comparison to the OEM ECM.

If you don't want or need what EBL has to offer you could just learn to tune the chip...

I'm tuning this with EBL and the TT-1 wide band.

Parts needed for swapping EBL into a 93-95 truck with auto transmission...

-24 and 32 pin ecm harness connectors (black housings)from tbi equipped cars,trucks,and vans 86-92 model years. Although manual transmission trucks up to 1995 model year should have these connectors as well. These connectors are also for sale through dynamicefi.

-esc module with connector and knock sensor*. These can be found on much of the same vehicles listed above,provided the donor vehicle has an engine of the same displacement.
*note: it is best to use a knock sensor from a vehicle equipped with an external knock module,but is not absolutely necessary.

That's about all that's required to make the swap other than other tools and supplies needed for any automotive wiring project.

Bob @ dynamic EFI supplies different repin guides for swapping from the 7427 and its variants to the EBL depending on if you plan on using the stock pcm as a transmission controller or not.

is it easier to tune with the ebl instead of getting the ostrich 2.0? It seems to me that the ebl is basically a faster pcm like the ones that came in trucks 93-95. Can someone correct me if im wrong?

[Doober]

Never looked into Ostrich. EBL is almost plug & play basically, point & click after everything is hooked up. I can make changes to my program if I want, and within 5 minutes be to the truck, flash the new .BIN to the ECM, and be back in the house.

[dualtbi88]

That's what I like about it. I'm using Tuned Pro RT.
It's easy to use to make program changes especially with the the 3D graphs.
Then I use the EBL to flash it to the ECM. I data log and use the VE learn feature to help with the tune.

Not to mention I have the ECM picked up where it belongs and you can see how I access the ECM through the tiny port I made in the dash; no one notices it.

When I'm logging and tuning I just pul the laptop on the seat plug it in the dash and off I go.
After I run the VE lean for a while, I stop the learn save the bin, open it in Tuner Pro to smooth the graph save it then flash it to the ECM.

If I didn't like how the truck ran with the new tune I can switch the bin (while the truck is running) instantly compare the difference. I have 8 different saved bins programed to the ECM I can swap with out using the laptop. I have the little EBL bin switcher for that.

[Doober]

I keep telling myself I'm going to get an old netbook I can put the EBL stuff on, and keep it in the truck or just park it in the house somewhere. My laptop is a 17" gaming type and it's also heavy so it's pretty cumbersome taking it in/out and keeping it frkm moving around. A netbook I could just keep on my lap if I wanted to, or set it on the dash where I could see it just over the cluster.

[dualtbi88]

Right now I'm about to sell all of it a just put a pair of carbs and be done with this. I'm getting absolutely no help from anyone on this.

Sorry for the rant. I emailed Bob about the VE tables not loading and some advice on tuning. One file he said to use wasn't on the CD that was sent with the EBL. I USED the next available bin file he described. The engine ran like crappy with that bin. I found the VE tables dropped of a cliff after 4500 rpm. So I had to adjust the tables to add fuel above that level. I got some better results. I was able to get some power up to 5500 rpm for once.
