I had a motec m130 installed into my boosted built/forged 4b11T setup a couple of months ago and I recently started having an issue where the LTC module is reading what appears to be an incorrect AFR reading. The incorrect readings have happened at idle, crusing and WOT at this point. It showed between 20 to 40 AFR while cruising and 22 AFR during a WOT pull as well as a couple of items with no afr recorded at all in my logs. My aem gauge showed 14.7 and 11.6 during cruising and WOT respectively so it appears to be the motec ltc unit. I'm not getting any fault codes or warnings and with it being part of a CANBUS system i thought it did self diagnostic tests to insure the integrity of the data, so my questions are 1) does this appear to be a fault ltc or bad wiring and can you tell which from the attached data? 2) why isn't a warning showing up and 3) shouldn't the self diagnostic indicate there is an issue?
Thanks in advance for your help.
