I don't know what the differences are between systems, how are some made to be tuned and others are not?

i'm not trying to speak for knuckle, but this is the way i see things.

if the mfg of the hardware does not supply the required software applications and information to tune the EFI system,  the mfg did not intend for the system to be tuned.

FAST, BS 3, holley, edelbrock, and others have created hardware and supplied software to tune their aftermarket efi systems.  MegaSquirt will give you the source code and tell you how to build and compile their software if you so desire.

ford would have never guessed that the EEC-IV would have been hacked and people would be doing what they are with their hardware.  i doubt ford ever intended for the EEC-IV to be tuned by the end user.

just my opinions, cheers, claude

That pretty much explains it, really.

For me to use some form of OEM ecu and have any tuning control would end up being nearly as expensive as an aftermarket setup, only with less flexibility and a pita to tune.

With the volley setup, I can do whatever I want and if ever decide to use nitrous or boost, the ecu can handle it natively.
