Hey boyz...

Today i brought a ECU for my manual conversion. Was browsing thru the wreckers today when i came across a EB2 4L manual ECU. Was wondering if this will work on my 3.9l? (if it wasnt smartlocked) Ive already put the 3.9L manual ECU in and it runs ok with the auto, want to try out a 4L tho.... any thoughts??
Also, what is the difference between the 87DA and the 90DA series of ECU's? My EB1 (with the 3.9L) was running a 90DA. Any difference in performance between the 2?? Im assuming its just on the auto ECU's because of the 4spd intro in the EA2 and the manual 3.9's use the 87DA right until the 91DA 4L. True?

Cheers

Brent

You can use the 4.0 manual ECU on your car but theres no way of physically telling if its Smartlock. Plug it in and if it goes then it isn't

Took me like 2 hours to type that and get it lined up properly, hence the full stops. It deletes multiple spaces for some reason:priest:

I got all that Karl...


What i need to know is if the 87DA 12A650 AX is the same as the 90DA 12A650 AX? Was there a 90DA version for the manual MPI 3.9L?
