Port Mod for MPFI
For those that want to use an EBL Flash system with their high performance multi-port fuel injection can now have the injectors firing in batch mode. The Port Mod changes the injector firing to once per engine revolution and is available for either a 6 or 8 cylinder engine (4 cylinder engines do not require the Port Mod).
The installation of this modification needs to be done here at Dynamic EFI. It is a small 1" x 1" PCB that is installed into the ECM.

The Port Mod option is only available in conjunction with the EBL Flash system

Re: Port Mod for MPFI
With the exception of the '89 TTA all 3rd gen f-body port injected engines are batch fire. This means that all injectors fire at the same time. Be it a 6 cylinder or an 8 cylinder they are batch fire. All injectors fire at the same time.
The '89 TTA is SFI.
