EBL SFI-6 Flash System



Please see Shipping for pricing and options including International.

The EBL SFI-6 Flash 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 SFI-6 Flash

The EBL SFI-6 Flash includes the BIN, What's Up Display, comm cable, ECU/XDF files and documentation. This is the self install. You may also purchase a complete EBL SFI-6 Flash ECM. This is the listed ECM and the EBL SFI-6 Flash installed, fully tested and warrantied.



The EBL SFI-6 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 GM ECMs. 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, alcohol injection control, lean cruise, cranking prime pulses, ability to select open loop modes for cruise, deceleration 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.

What Else is Required:
Installation of the Embedded Lockers hardware:

The EBL SFI-6 Flash board needs to be installed into the ECM, replacing the MEMCAL. This may be accomplished by the purchaser or by Dynamic EFI. In order to do a self-install decent soldering skills are required. For those purchasers that do not wish to install the EBL board themselves Dynamic EFI charges a nominal fee for installation. There is also an option to purchase an ECM outright with the EBL Flash board already installed.

Link to self-install guide


1) A MEMCAL is not required when using the EBL SFI-6 system.

2) If a MEMCAL is available it may be used to provide limp mode and a knock filter. However, it will protrude from the case by about 1/2".

3) Knock filter is optional. For a knock filter there are several options:

Use of a MEMCAL (protrudes from case)
Use of a pluggable knock filter such as from a 3.8l later Buick or matching engine
Use of a knock filter from a MEMCAL. User must solder to EBL board (fits inside of case)
Use of an external knock filter. This is such as the stock 3.8L Buick Turbo setups
