I have had a look through the threads but cannot find a definitive answer to what value I put into the periphery section that enables the immobilizer check.
To explain, I have an EDM evo VIII 260 and have download the ECU and hence have the immobilizer code but I am intending to flash the ralliart rom onto the ECU but understand that the immobilizer is disabled by default.
From comparing the ROM's I notice that the ECUperiphery 2 hex values are different (standard ROM 89DF and ralliart ROM 89D9). I can call up the periphery tables but could use some guidance as to what to change or look for to enable the immobilizer on the ralliart ROM, thanks.

(The ralliart ROM I am using is 99270000)

 

You will probably find that "enabling" the immobiliser on the RA rom will not let your car start.

immobilisers seems to be one of the things not common to all evo's and how they are connected as well.
