Can you use a AU series 2&3 ecu into a sereis 1 AU?

[78xcgxl 241]

Hi all,

I was just after some info if you can you use a AU series 2 &3 ecu into a series 1 AU? Now i know that series 1 AUs did not come with smart shield or whatever you call it haha and just smart lock like E series falcons therefore it wouldn't probably work straight off the bat. But could you however use say for example a series 3 ECU with a J3 chip to get rid of smart shield & smart lock and whack it into the Series 1 AU? Will this work??.

Also another question did Series 1 AUs come with OBD-2 ports or was that only on the series 2 and 3 and apart from series 1 AUs not having smart shield and therefore a different programed ecu, is there anything different on wiring side of things compared series 1 AUs with 2&3 AUs?

Any help or ideas on the matter would be greatly appreciated.

I'd prob just put a series 1 back in it, save all the trouble. i would say it would end up not working like the ef's have the different colour boxes, i would think au would be the same

Thanks gromet88, the reason i am asking is that if i need a replacement ecu i can use any AU one. Keeping in mind this going to be for my 4.0l conversion for my xc and the ECU will be only used for engine management (using a T5).

 

Anyways i asked the same question on another forum and i found out that if  i wanted to run series 2&3 ECU into a wiring harness from a S1 it is just a matter of programing the j3 to also get rid of smart shield as well as the smart and swapping to a series 2&3 MAP sensor as Series 1 have a slightly different MAP sensor on the BBM manifold.
