have you attempted to look for existing information?

I believe those to be the cam angles for the VVT. Optimal angles will change with varying factors. The best way to configure this is on a, IIRC, eddy current dyno. Doesn't work well with this type of ECU or tuner though.
enabling OP and adjusting the cam angles works as commanded just fine. what do you mean it doesn't work well with this type of ecu or tuner? you mean ecoboost motors?Originally Posted by mechanicboy
The point of the post was about Ecoboost. I read through all the Coyote stuff about these tables and with Ecoboost being turbo/force induction, I'm wondering if anyone has experience playing with these on an Ecoboost and the results of there findings if they want to share that. So much of this is all secret squirrel right now and HPtuners is playing catch up with SCT for the ford market.
HPTuners has not been in the Ford market very long, so yes, there is an element of "catchup" but a lot of us are willing to work through it because it's, IMO, the best interface to use, and for a lot of us, what we know very well from years tuning GM stuff.
Agreed.
So Higgs,
what is your take on the Optimum Power Tables and Ecoboost with stock cams?
I was referring to the dyno that holds a steady speed while adjustments are made to measure gains or losses in real time.
we have found some gains (nothing ridiculous) with stock cams on Coyote stuff, without testing some different angles I couldn't tell you for sure about the EcoBoost. I do think enabling and using OP is a good idea as it gives you a consistent and separate controllable set of variables to use at WOT.
My thought is little gains on the Coyote might be a little more for the Ecoboost with the forced induction. Maybe someone here are do it and doesnt want to say or maybe now someone will try it and report back (hoping there is some free HP in there)
So from all the reading I did, I understand that there are physical limiters on the cams so you can play with these and the engine will not let you do too far?
too much overlap will just blow boost out the exhaust so maybe, maybe not.
