EPROM ECU?

I know...I know, use the SEARCH function! Internet in Iraq is a whole hell of alot shittier than U.S. internet, so it takes forever.

What is the Difference between an EPROM ecu and a NonEPROM? which ecu will i need for my ggsx conversion to ggsxT?

I thank everyone in advance, but they keep me busy and tired here so i cant really wait for stuff to load or for the search.
 

You need an EPROM ECU if you are going to need a chip to compensate for equipment that is other than factory stock. If your conversion uses a stock 1G/GVR-4 MAS and 450cc injectors, you can use either ECU. But, if you decide to use a 2G MAS and 550cc+ injectors, you will probably want a chip to correct for those changes, so you need an EPROM-type ECU.
 

I can't remember where but just recently a company will turn your ecu into an eprom.
