EBL ECM Choice

Dynamic EFI

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

EBL ECM Choice

In deciding which EBL system to use, here is a quick list of fuel injection systems each is capable of running:

EBL Flash:

A single 2-bbl TBI unit on a 6 or 8 cylinder engine
A single 4-bbl TBI unit that uses port injectors, low impedance injectors recommended
With the 4-Injector Upgrade, can run either a 4-bbl TBI unit or two 2-bbl TBI units
With the Port Mod, can run a MPFI system on a 6 or 8 cylinder engine (batch fire, specify cylinder count, not user selectable)

EBL P4 Flash:

A MPFI system on a 4, 6, or 8 cylinder engine (batch fire, user selectable cylinder count)
A single 1-bbl TBI unit on a 4-cylinder engine. Using a '7749 ECM can run a single 2-bbl TBI on a 4-cylinder engine

EBL SFI-6 Flash (soon to be released):

A MPFI system on a 6 cylinder engine (sequential fuel injection), got boost?

General Information:

All three EBL systems are speed density, that is they use a MAP sensor (1, 2, or 3 bar).

None of the EBL ECM systems are capable of running an 'E' automatic transmission. One can run the stock PCM for trans control and an EBL Flash (or P4/SFI-6 Flash) ECM for engine control. Many users of E transmissions have done this.

TPI MAF systems:

To use an EBL system on a TPI MAF car, Firebird, Camaro, or Corvette, either the EBL Flash w/Port Mod or the EBL P4 Flash can be used. It is easier to use the EBL Flash system as only a small number of EFI harness connector pins need to be moved.

To use the EBL P4 Flash system in place of the MAF ECM, most of the harness connector pins need to be moved along with adding another connector. Although, the EBL P4 offers more capability which can make a swap to it worthwhile for the additional labor.

The MAF is no longer used and the wires for it are used to connect the MAP sensor to the ECM.

Differences Between EBL Systems:

A.I.R. (smog pump):

EBL Flash: no
EBL P4 Flash: yes, both 1 & 2 solenoid systems
EBL SFI-6 Flash: yes, both 1 & 2 solenoid systems

Electric fan:

EBL Flash: 1 fan
EBL P4 Flash: 2 fans, better control then EBL Flash
EBL SFI-6 Flash: 2 fans, better control then EBL Flash

N-Alpha mode:

EBL Flash: yes
EBL P4 Flash: yes
EBL SFI-6 Flash: no

Oil Temperature:

EBL Flash: no
EBL P4 Flash: yes
EBL SFI-6 Flash: yes
