Alright so i am swapping over to OBD1...had a resistor put in the computer so the knock sensors will read correctly. I put the computer in tonite (still needs tune) but when it runs for about 20 seconds the fan turns on as normal then goes nuts and instanly doubles speed. I do have an electric water pump and my fan did rub on some things at one time....but i did not do this until i switch the computers tonite. So will the tune fix this or is something else wrong?

 

ttt...need some help asap
