I sent the top screen shot of the MAP sensor to Edelbrock and they have already responded! They also think that the MAP readings are fluctuating too much. I just finished an actuator test with a hand vacuum pump and sent them the results. We'll see what they say.
Octane setup is for 91, no 93 around here and only one place for 92.
This run was the third run for the day. (Took me two runs to figure the software out.) So I suspect the SC was heat soaked somewhat. My thinking is I need to go after the heat soaking/removal as a project to improve overall performance (and probably improve knock retard). I'll throw up another thread to gather ideas later or if you have some, I'd like to hear them.
I've been fiddling with Euro builds, so I speak the lambda lingo pretty well.  Gotta say these things are a lot simpler that the Audi's where you have literally controllers controlling other controllers in series.
Regardless of this discussion, the E-Force is running great. I just like to dig in to these systems and learn new things. It still hits 450 ft.-lbs. at 2500 rpm and 560 rwhp as it sets. |
If this was the 3rd good hit and your IATs were 182, then that's not bad in 90 degree ambient. Other than a larger heat exchanger there's not a lot more you can do there. The front of the Camaro seems to have some good air flow so that shouldn't be an issue.
That tune on 91 is what I'd call pretty good. Timing and AFR look good. The 1 deg of STKR isn't a huge deal. Better safe than sorry on knock sensor sensitivity, especially on 91 octane.
The MAP sensor would be something I'd have concerns about. But based on everything you showed and stated, everything else looks good for out of the box setup.
