a long time ago led 18 negative leg would run the fan no problems via relay
at some point it stopped and i just used my bypass switch to do it manually
my settings look good and tunerstudio green lights the tab when working but i get no led lighting up or action out of the negative leg
is there a way to test or trouble shoot the led 18 hardware?
also when i am tuning some adjustments seem to make no difference
in warm up wizard, if i jump up to 200% where the motor temp is at i get no increase in mSec pulse width???
pretty much the same in the fuel table, raise it way up with no difference in the pulse width
the pulse width gauge should be the ultimate fuel consumption meter right?
i have a weird lean spot right about 2500 rpm that will not change with huge fuel map increases or decreases
thanks matt

Re: led 18 fan control and q's
Try removing the CPU and applying 5 volts to U1 pin 9. See if the LED comes on and if the relay triggers. If not, it sounds like you've most likely got a burned transistor.
