i have a b16 delsol sol running s300v2 in a p28

b5 input works correct aka ac fan comes on and everything
a15 output does not ground
if i play with nitrous output with a15 and invert it i can get it to ground the clutch but this is not a permanent solution

i dont have another s300 or ecu to test

is there anything in the tune file im missing to enable or disable the ac

It sounds like the ECU may be damaged would have to be replaced.

wow fast reply. id assume it can it be repaired? i have been trying to find where in the ecu that may be to inspect but havent had such luck myself.

if i jump b5 to a15 outside of the ecu ac does work correctly

We do not repair ECU's. You would have to try to find the bad components and then replace it to see if it fixes it. This is usually not cost effective, and it is much cheaper and easier to replace the ECU.
