Can someone verify my understanding of the wiring on the O2 sensor plug.
Pin 1 - O2 Heat - 12Volt +
Pin 2 - Ground - 12Volt -
Pin 3 - O2 Return (Upstream or Downstream) - ?
Pin 4 - O2 Signal - ?
My questions are on Pin 3 & 4.
Generally, 1 of these is a 0-1 volt output from the sensor since...
No, it's not solved. I quit for several weeks but recently just came back. I thought I might have accidentally fixed it with all the fiddling with different things, but that's not the case.
As before, I'll be driving along and all of the sudden everything resets / turns off and back on. But...
I've used Alpha OBD, AppCar, HPTuners MVIC3, and had no codes, until just recent. I received a Lost BCM Communication code. a U something, I wrote it down at the house.
Ok so I have a 2019 Laramie Crew Cab 4x4 5.7L non etorc. She generally sits in the driveway during the week as I travel extensively for work. So, I only drive her occasionally on the weekends.
Here is what has happened so far.......
3 weeks back, Friday went out to dinner with the little...
Not sure if the HD is the same as the standard Ram. Also 2020 year is going to be different than the 2019, RAM made a lot of changes from the 2019 DT to the 2020 DT on the BCM and ECM setups from my understandings.
Did you make the correct wire modifications under the hood too?
Need help!
I have lost my gear display in the lower center section of my dash gauges.
I can scroll thru the steering wheel setup and select display gears "ON" and nothing appears in the | | | | area at the bottom. I used to have it show like P|R|N|D and the gear I was in. I can't seem to...
Well, spent Easter weekend wrenching on the truck. I managed to get the long tubes wrapped & installed, swapped the ECU, added a catch can, and some other miscellaneous things done.
I'll do new plugs with the intake swap. I just haven't had time to mess with the intake and get it ready...
I'd be happy to give him a call Monday if you seriously want one, just PM me. I would imagine he has a couple laying around in his yard, after all he runs one of the biggest part recyclers in Dallas.
Oh, I plan to clean it up, once I get a chance to strip it down.
Thanks for the porting link, I was thinking about that as I have access to a flow bench. I'm just curious about the difference in grinding the composite compared to the cast. I would assume I might have to get some different...
Look at what I found.
And all I had to do was buy a case of beer for someone.
He was even nice enough to pull it off the truck for me. I might have to take him to lunch.
Also, I'm guessing I'm a little confused with some of these write ups on the 6.4L swap. Some of them are using a MSD8969 Timmer module to control the variable intake runners. I'm guessing this is either a requirement on the cars or say an older 5.7L that's being converted?
Because doesn't my...
Today I did to do some maintenance on the truck. During the winter freeze, I thought I had given enough time for the washer lines to thaw out, and well I guess I hadn't so the pressure blew of the hoses from the nozzles. Anyway, I pulled the hood heat shield off and fixed it. Well last night...
