Can?t seem to find a straight answer, but for anyone who knows the answer it would be much appreciated. Application here being a L83 w/ aftermarket cam running 0 degree lockout block in the factory phaser. That being said now that the phaser is locked what?s the total degrees of timing advance?
Reason being I read somewhere p0011 over advance code could cleared once the ecm stops commanding advance that?s no longer physically possible due to the phaser being locked.
The cam will be locked in the full advanced position. You'll disable the P0010 and 11 DTC's Which cam are you running?
That’s Logical thanks for the quick answer. As far as the codes they’re disable and have been, but being permanent they still pop up when I scan for dtc’s lol.Quote:

Started over fresh factory tune when I get my vt in line and my engine/zero pedal/immediate torque mirror which would be beuno, it’s diving -20 degrees. I think the airflow increase/changes in the torque model are making this extremely difficult or it’s a modifier I’m missing. In SD I can’t even safely drive it stuck in negative it will lurch once you pedal it hard.

Running a dang near identical setup and about to start working on a self tune. Curious if you'd be willing to share your file so that I can see the main tables you needed to adjust?Quote:

You need to get the airflow models correct first and foremost.
just finished my stage 2 tsp cam swap with all the other same parts as you. i have larger injectors,l86 intake and tb. Turbo and stage 3 trans by circleD and billet 2 piece triple stall.Quote:

Short story I followed Matt Standford. It is a base starter tune I will go over it all before big boost.

Starts up no codes all misfires gone idles perfect and 0trq at idle. my WB O2 is reading 1.0-1.02. stft are under 10.*oh i have misfire under 3000rpm off for my 2 step but can still see in misfire history but i have all 0. and no disabled codes other then emissions.
But I think there is some unwritten rule the computer needs so many miles to relearn for the tb,intake, and cam. even with the relearn in special tools.
Man I am living this right now. ANy update on the process? I took a bite of a big apple. New l83, ported heads, PDS cam, LT4 injectors and HPFP. Truck runs but barley idles.
I backed off all the changes I made to prep for the swap. added just the LT4 injecor data and removed P0010 and 11. I did not zero out the Disired angle Low Med High. Should I ?
