mefi scan question
 

just bought this program for mefiburn and i was just wondering how to retrive trouble code using it
thanks

oh and also how to clear the trouble codes as well
Thanks

I purchased MEFISCAN a couple weeks ago. The trouble codes are shown under the item list as M21,M23,M33, etc. A 0 is a code not tripped and a 1 is a tripped code. I have not found a way to reset trouble codes from the program I have found some errors in the conversions and have made the corrections. Check your MAT (manifold air temp) it should read the same as the coolant temp with an engine sitting overnight, I found MEFISCAN reads the temp wrong. I also have found how to recover the total engine hours. Over all MEFISCAN is great, I really like being able to make custom screens(dashboards) and all of the data logging capability.
