Bringing TBI and Multi Port Fuel Injection to a New Level.

EBL Flash-II System

_Note that you must send us an ECM for the EBL Flash-II system to be installed into_
_Once upgraded this same ECM will be returned to you_
_See further down for ECMs that can be used_

EBL Flash-II - We install into your ECM - $440 USD....................................

The following options are ONLY for the EBL Flash-II and mustbe installed at Dynamic EFI:

EBL Flash-II Port Mod - $30 USD...............  Link to Port Mod information
EBL Flash-II 4 Injector Upgrade - $85 USD....................................................

Please see Shipping for pricing and options.

The EBL Flash-II does away with the burning and swapping of chips. On-board flash is programmed with the What's Up Display. No more swapping chips, no more ECM on the floor of the vehicle. Put the ECM back into place under the dash (or seat, or kick panel or wherever it is intended to be). Then flash and data log a new calibration right from the same cable via the What's Up Display program.

EBL Flash-II

The EBL Flash-II system includes: the What's Up Display, EBL Flash-II installed in your ECM, communications cable, BINs, ECU/XDF files and documentation. 


The EBL system sends ECM data to a laptop or PC running the What's Up Display program. It is simply the best and fastest data logger available for any GM ECM. The data stream contains all available engine and vehicle parameters.

Included on the EBL board is eight analog input channels. The data from these inputs is included real time with the ECM data. These analog inputs can be used for data logging WB O2 units, fuel pressure, and any other 0 to 5V linear device (accelerometer, oil pressure, oil temperature, suspension travel, and so on).

The software to run the engine is the result of years of effort. It has been enhanced to support engines from stock through high performance monsters. Handles boost to 30 psi. The EBL code provides functionality not found in stock ECMs. Wet N2O control, lean cruise, cranking prime pulses,  ability to select open loop modes for cruise, decel or idle.

For example:
The enhancements to the ECM code are too numerous to list. Once tuned your engine will run better then it ever has.

If your vehicle uses one of these ECMs, the EBL ECM will be plug compatible. Most will also be pin compatible, some will need a terminal moved on the harness connector (easy to do). In other words, unplug your stock ECM and plug in an enhanced EBL ECM with all of the features.

Note: be sure to check the service number of your current ECM. Do not send one in that isn't on the above list. Here are two pictures of where the service number can be found...

Installation of the Embedded Lockers hardware:

The EBL Flash-II board needs to be installed into the ECM, replacing the original little board. This needs to be done by Dynamic EFI.


* Crossfire Corvette/Camaro/Firebird:

For the EBL Flash-II ECM to work in a Crossfire car some additional changes are required. This is due to the type of connectors each ECM uses. The Crossfire ECMs use an edge card connector, while the EBL ECMs use the pin style connector.

Note: the OEM X-Fire ECM will not work with an EBL Flash-II system. The ECM must be one of the above.

Basically there are three options:

1) Replace the EFI harness with one from a TBI car/truck with the proper connectors.

2) Cut off the current ECM harness connectors and splice on the pin style connectors.

3)  X-Fire Performance (XFP) has developed a newer HAM board for crossfire injection which is from the same company DCS, that the HAM board originally was from. The newer HAM boards are a better design and more reliable overall. Call XFP at 480-269-1327 for more information.

** MAF TPI Corvette and Camaro/Firebirds:

To change from a MAF TPI set up to an EBL Flash-II ECM requires a few changes. There are some ECM harness connector pins that need to be moved. A MAP sensor (1, 2, or 3-bar) is added using the existing MAF wires and plumbed to the plenum. The MAF is no longer used but may remain in place.

Then plug in the EBL Flash-II ECM and turn the key.

This is an easy and great upgrade to get away from the expensive MAF sensor and burn-off relays. And is even better when boost is involved.

The Port Mod option for the EBL Flash-II ECM is required for this application.

Note: the OEM MAF ECM will not work with an EBL Flash-II system. The ECM must be one of the above.

*** Laptop Requirements:

The What's Up Display will run on XP, Vista, and Windows 7, 8, 8.1, 10 or 11. The What's Up Display requires a USB port on the laptop to communicate with the EBL Flash-II system.
