A guy from the dealership said he is having oil pressure issues when the DOD kicks in on his truck. Can I just delete or turn off the DOD in the computer with out effecting anything else? Also, what ECM is in the 07's? E40/38/or 67? I know there are classics and not. He said the sixth number in the VIN is M. I am supposed to get this done tomorrow. Any suggestions? Thanks.

 

E38 ecm go to B0921

 

if he has less than 100k miles have him take it into the dealer and get it fixed. then shut it off via the tune.

 

Thanks for the reply's guys. This thing is a mess. It had the lifters replaced at less then 10,000. Then blew up at 122,000 on a hunting trip and was replaced by family friends in WV. Supposedly the new motor had only 7,000 miles on it then. Well he drove it out of the gate and got a low oil SES. He immediatly turned around and they told him don't worry about it. So today I check it out and it only has 8psi at idle and maybe 12psi at 1,000rpm. Then driving it makes about 23psi. The AFM turns on but doesn't reach the 58psi needed to work and throws another code. I think it need a rebuilt short block. I did turn it off and messed with the timing some to help drivability and fuel milage. He is happy for now.
