changing numbers for fan switch doesnt work
 

sup guys my fan is coming on at 105-107 .ive been messing with the datalogit with no luck on setting 3 at fan vs water temp to lower down temp for when the stock fans come on .
ive changed all three settings to 35 with my engine temp warmed up to 78 and still nothing. any suggesntions?

Which car is it in, the 87 or 93?

i had this problem with a bad ground on the front bumper.

use the test points to check your fan relays
