How to DoD AFM delete or disable.

[blindsquirrel]

Yes, I know the thread is a few years old, but do these 5.3 camshaft settings apply to the 6.2 (L86) as well if deleting DOD/AFM?

If your DI L86 is converted over to port injection and using a Gen 4 ECM, then yes.

Whoops, I could have sworn it was a gen IV engine, not a gen V. My bad.

regarding this reply
Transmission > Torque Converter > General > "Use DOD Slip", and set that to disable

Very new here and just learning .. having a hard time finding what that setting actually does, even when you have DOD and AFM disabled already



sorry to revive an older post. Not finding too much with google foo

Just need some advice here but I've done the mechanical delete and adjusted the tune. I disabled dod and I also zeroed the cam settings. I personally couldn't find the dod slip in the transmission tuning. I'm having issues with losing oil and with rough smoking start. At low rpms it backfires but it comes out near the intake not the exhaust. I only did the delete because I had a dead lifter and read for months on what needed to be done. I have a file of it running but I'm still new to this and want to learn. I will say I didn't change the valve seals and I also switched to a high pressure pump but I only get 60 psi roughly. It's a 2008 chevy silverado 5.3. I did head gaskets, exhaust gaskets, timing cover gasket, valve cover gaskets, crank gasket, non dod cam, stock non dod lifters, non dod valley cover, and other small gaskets at water pump. I replaced stock oil pump with high pressure oil pump putting my idle around 40psi and 60psi driving. I have no issues when I'm on it just when I'm at idle or low rpms. I wil add that it's the worst right at starting then calms down when the rpms drop.

Just to verify, would like to do this delete on my 07 5.3 in our suburban and I just need to follow the steps;

Engine -> Fuel -> Lean/Fuel-Saving -> DOD dropdown menu
Set to Disable.

Engine Diag
Find DTC's related to cylinder deactivation. Found in P3400 and on. Uncheck SES Enable and set to No Error Reported.

Planning on doing the delete kit at a later time.

Thanks for your help.

I’m pretty new to tuning EFI engines and learning more every day but my prior experience has taught me that if backfiring into the intake manifold it would be best to recheck the physical engine before proceeding with tuning. This should not be happening unless something is wired wrong or there is a camshaft timing issue.
