Hi Guys , I have 2 ecu that are for my 4age AE86 ADM conversion .

The one that came with the car is 89661-12080 blue label , but on the list of all 4a-g ECU I have it does not appear.
I have heard that the best ECU to use is 89661-12051 orange label ( on the list as a AE86 JAP 83 TO 87 )

Now my problem is while the car run ok with the blue one , when I fit the orange one , it starts and runs fine , but engine will not turn off via the key.
Any one come across this before?????
