What are the voltage max levels supposed to read? RE: RE:CM 870 EGR TUNE UP GUIDE - madcash2 - 07-29-2017 Hi Guys, so finally got round to working on this truck. firstly i found that the ecm calibration was AB10424.14 which is from 10.21.2005 so i decided to upgrade it to the latest one on my list which was AB10424.23 from 9.8.2010 not sure if this would be part of the reason i am getting -readings but i thought id change it any way. I did some date recordings and from before and after the upgrade not sure if there are a data guru's who can decipher the problem from the data. I checked through the connections and all seems ok, even during insite monitoring the issue of the negative readings is not there all the time infact ive never actually seen it happening live ive only see the minimum recorded - data after its already happened. There are know faults codes either. Please if anyone can look at this and understand it better any help would be appreciated. here are the links to the data https://www.dropbox.com/s/phoy10h56ulwmpn/DML-20161231-154022.csv?dl=0 https://www.dropbox.com/s/gqqrx3vcgg4rofx/DML-20161231-172239.csv?dl=0 https://www.dropbox.com/s/m31lvkdnwim5xyi/drive.csv?dl=0 Cheers |
