i have an h reg efi xr3i cab that i want to put my turbo engine in, i have mfi bottom end that i'll drill cps in, efi head and loom from car, do i need to get a ofac or ofab ecu to use on it? i heard the ofac will plug straight in and i'd just need to change fuel pump and injectors, any help would be great as i plan to do it this comming weekend

 

OFAC it the one you need.

 

ofac is piece of piss . thats what im currently doing to my efi cabby

 

so will it just plug in the same? then all i'll have to do is connect loom back to engine and it'll run?

 

all ecu pins are same the ofac ecu willplug straight in

wires that need changing :
ISCV (able to reach depending on if using frst iscv or 3i iscv)
fan (needs changing to suit what fan your using)
amal vale needs adding but most dont bother (i havn't)
pin 2 on EDIS needs cutting and taping out the way
ACT needs changing.

belive thats it im sure ill be corrected if i missed anything.

hope helps.
