Lean Shutdown Issues I am having some problems with the following product:
http://www.dynotunenitrous.com/store...p?idproduct=67
My issue is that the switch does not display the correct AFR. I have read that some amount of discrepancy between values at the wideband controller and the shutdown switch is to be expected but I believe my values are off by an excessive amount.
As I cycle through menu 3 options I get the following results:
Option 0: Wideband=14.7, Shutdown Switch=20.0
Option 1: Wideband=14.7, Shutdown Switch=19.6
Option 2: Wideband=14.7, Shutdown Switch=18.1
In all cases the switch values would rise and fall as the wideband values fluctuated but they were off by the above amount. Also, I checked my incoming voltage to the switch (purple wire) and it read 4.07 at idle (wideband=14.7) and 4.76 (wideband=16.0).
Any ideas?
