Can we enable VVT with the editor?
Can we enable VVT with the editor?
The engine has it right?
I no longer monitor the forum, please either post your question or create a support ticket.
didn't see it off hand? but I guess I don't need it at the moment, going with a different setup.
I have an e38 2011 L77 (non VVT) and yes I did enable the cam phasers by specifying one did exist on the intake, and for the most part works great.
Only problem is VVT spark table doesn't work, so I'm contemplating migrating to e38 2013 L99 (VVT) OS to enable the VVT spark table.
Before I embark on a major migration to O/S 12653674, have I missed some prerequisite step to enable VVT other than specifying # of intake cams {B7955}?
Problem as above, {B5154} Cam Phaser Timing doesn't work on 12639270, yet it does on VVT O/S.
Is migrating to the L99 O/S the only way to enable VVT Spark table?
I checked the efilive OS compatibility list, went ahead and created a new tune from 2013 L99 VVT base (above) migrating from 2010 L77 non-VVT tune, seems the OS compatibility list needs updating with more detail to allow for the break in e38 ECU for the 2013 revision.
Anyways flashed 2011 L99 VVT base of same OS, works perfectly (some tweaks).
All this was to get VVT Spark BTW. I think it was worth it.

Intersting
Yes, so you can enable cam phasing in a non-VVT OS but to have VVT Spark active you need to run a VVT OS.
One problem is that the e38 VVT OS I've tried have incompatible speed limiter / cruise control source and modules, so no cruise is a bummer.
Bottom line is VVT with cruise control without spark adjustment or full VVT phasing and spark without cruise control.
I here you on that... slightly different trouble but I can't source a E67 with cruise that will work in a non factory application with manual trans!
Your best option would be a E67 from a 2010 Colorado it has factory 5.3L VVT and automatic, cruise will likely work without BCM, just need a resistive ladder cruise switch or efi connection 4 wire cruise to resistive ladder cruise signal out, box. Then send that cruise signal, brake signals, to the pcm, I bet cruise will work. You can use the same pins from your E38, just buy two new connectors and repin them.
