a/f ratio will no longer read richer then 11.85

[boosted crx-r]

I am retuning a customers car because it was reading 10.2afr under full boost. I proceed to tune and the wideband reads down to 10.25afr and the display and graph on the s300 will not read any richer then 11.85afr. it works perfectly fine until it gets to 11.85 and just stops. this has never occured any other time and now this problem is continuous. is there a setting somewhere that needs to be changed that I may have accidently hit that will make it do this? any help or input will be greatly appreciated!!!!! -mike

Go to options>sensors>select AF>make sure the units are set to air/fuel and the display min is 10 and max is 20

try that and get back to me.

You also need to double click on AF if in the sensor list and make sure it is set correctly as stated above.
