ive had a search and there are conflicting stories on what its out of

for those not familar its an ecu catch code

5 Speed ED XR6

shouldnt the ed xr6 be 2tad.??

and afaik the 2dad is a std eb2 or ed manual??

if your getting conflicting info about what its from call ford and ask them what the ecu is from..

I can conferm that 2DAD is ED EX6 Manual..
Std EBII/ED manual ECU is 1DAD

unless my Genuine ED XR6 had a fake ecu, 2DAD is ED XR6

ok
the reason i said that is
i had a ed xr6 manual a few years back and it had a 3tad ecu.

3TAD is LWB Tickford ECU, ED XR6 Wagon, XG XR6 ute..

well
thats the thing. i cant confirm that mine was the original ecu. i got the car second hand and it was a genuine 1994 ed xr6 sedan(untill it got ritten off)lol

like i said ford will know 100%
im only going on what i have found with my personal experience with these cars..

the information i have comes directly from the Genuine ford workshop manuel..
