subaru sti ait sensor

i have a gems implant on my sti uk MY05 and cant get the ecu to recognise the manifold air temp sensor i have set map to on and maf to off and repined the ait wires to the ecu and that all apears to be fine but the ecu is only reading the default setting of 55degres so the als wont work i can lower the default and make the als active but its not ideal
any body got any sugestions thanks

Hi, apologies for the delay, we have been closed for the christmas period.

The Subaru 05 Ecu has 2 inputs on our unit for Air temp Pin B27 Air Temp AIT Source AIT 06 or Pin D15 Ptemp AIT Source15.

IF you call up ADR06 and ADR15 in the Parameter window you should see one of these input changes with Air temp then you will know which number to type into AIT source.

Hi there thanks for the reply
i have looked at the software and in the options page there dosent appear to be anywere to enter AIT source i have looked at an older version H0.85 and it is clearly there for all to see but on my new ecu (subaruuk2 S260) i cant see the AIT source window !! so any further help would be apreciated
thanks again

Sorry to give you information on the later Ecu’s but I missed your comment about V2.60. The Air temp on this version of ecu is on Pin B27 for the signal element.

There is a raw parameter called ADR6 which should read 64-65000 open circuit 39000 at 13 deg hopefully you have used pin D14 rather than B27.

Regards

still a bit confused i have just checked now and in my parameters i dont apear to have a n ADR06 to view the raw signal on ?? any further help greatly appreciated thanks guys

In your options list, check Air temp max and Air Temp Min. Are those valid values?

what values should i have for air tenp min max ??

To test the sensor input, move limits to extremes, do you get any reading that does not track the default?
Also is ERROR1 = 0xXXXXX1XX, where X is don't care, 1 means error 0 OK.
With the sensor removed do you measure 5Volts on loom pins?
