First Gen 5 - a couple quick questions.

[Boosted2.0]

I was hoping someone may be able to help me out with a few definitions / interactions. I am new to the Gen 5s and the definitions and tuning methodology are quite a bit different from what I am used to on other platforms. Have been reading and searching through gen 5 posts for a few days and haven't been able to find a conclusive answer:

The main things I would like to confirm are:

1 - Which retard data item is actually being driven by knock? There is "retard degrees" on the log graph and then there is "total knock retard" and "knock retard" on the data list as well.
2- On the cam position, I have read that the values for variable cam position are in degrees of retard from maximum. So 0 is full advance, 2 is 2 degrees retarded etc. I just want to confirm this is true?
3 - the logged value for cam is "intake cam angle" is this degrees of retard as well or degrees of advance?
4 - I have read that the VE tables are still referenced when the vehicle is in MAF mode for various functions. Can you confirm this, and maybe direct me to which are the primary VE maps that need to be dialed in?

Many Thanks!

Yes the VVE is still used even in MAF only mode. VVE is under the EDIT tab because there are no primary VE tables. There should be 4 "tables" to choose from and you'd be making changes to both the open and closed tables. No need to change the DoD ones.

Knock retard = retard only from actual knock
total knock retard = retard from burst knock retard, "actual" knock retard and I think a few other things

Got it - thank you!

Yeah - from watching the logs it sure seems like total knock retard is pulling from numerous sources. Thank you!

Could anyone possibly answer the cam control questions I have?

2- On the cam position, I have read that the values for variable cam position are in degrees of retard from maximum. So 0 is full advance, 2 is 2 degrees retarded etc. I just want to confirm this is true?
3 - the logged value for cam is "intake cam angle" is this degrees of retard as well or degrees of advance?

Also if there are a couple of particularly good threads on the gen 5 control strategies, I would be very grateful if someone could post links, ir tell me a user whose posts I should search for etc. I don't want or need to be spoon fed, but I am finding the sheer amount of threads on the Gen 5s a bit daunting.

Thanks!

Not too much info going around for gen5 stuff. I recently just finished one. Its actually not too hard once you grasp it. Maybe search out driver demand tables. That might help you too.

[Higgs Boson]

no need to alter driver demand when the rest of the tune is right.

HPTuner should make you pass a quiz on this prior to the software being able to flash!
Anyone who's even CONSIDERING messing with their Gen5 should read and understand this! Thanks Higgs!
