Bone stock 5.3 E38 Silverado. K&N CAI, 212/218 111lsa cam. Otherwise stock.
I'm finishing up tuning on vve and maf today for sub 4000rpm driving. Up until now I've tuned off of Ltfts multiplied by half in paste special. Knowing what I know now I wouldve used short trim averages and began with direct paste pct without halving.
I've just purchased an AEM can bus wideband for wot tuning and have some newbie concerns that I'm seeking understanding on.
I'm assuming I'll tune VE first, then MAF. My question regards the PE table and lambda both. Not necessarily together. If I'm in speed density logging and hit ve on WOT will my error percentages reflect the PE interceding? Or will I be looking for .85(generality) and the pe multiplier cause me to go way rich?
Interjection, I feel like I'm answering my own questions on this lol. I've exhausted the gen 3 and 4 forums searching but have found little clarity, at least under my keywords.
Also with the PE Table. My stock is active at 5000rpm and 87pct tps. Is this an either/or to activate, or are both required? If both are required, where does that leave me from a low rpm roll stomp in first gear at 10mph? I'd hope not stoich until 5000rpm.
Lastly, are there any PE tables that need to be modified for performance safety such as generalizations mentioned already or even for part throttle to wot transitions? Is it standard practice to lower the tps pct or rpm? 5000rpm seems excessively high, so does 87pct throttle. Usually if I'm over half throttle I'm "playing", and as for 5000rpm, That's already past torque peak.
Forgive me if the vve table is already on top of that for me as well. Just looking for more clarity that I've not came across yet.
The truck will be final tuned back with the maf. Same thing here, would I want to activate it sooner afterwards?
I'd honestly expected more wot wiriteups or info than anything and there seem to be way less of those than anything else. I've found 1 that's way dated, but seems to be from a credible source on the forums. And two others referenced with dead links.
Last question, and this is me pushing my boundaries possibly, but target a/f seems to be all over the place here as well. 12.3-13. I'm not seeing anyone talk about ramps though. I'd imagined shooting for about 12.3-4 til peak torque then 12.8 after. Are yall ramping these transitions. Or going from one to the next, or just a straight afr across the board. I've seen that used AND recommended as well but cant wrap my mind around it being optimum.
Many thanks.
