Yes Chris. I'll be more than happy to make another log. I'll have to get the customer back over here tomorrow though. Hopefully you don't mind waiting.Quote:

why is your map only 84kPa at full throttle?
Yeah I was wondering this aswell :confused:Quote:

Maybe intake manifold restriction?
Here ya go. Quick standing rev log with the PID that was requested.
this is a tough one, i'm still wokring thru some of the possibilities but i think it is related to the torque calculation and possibly the high alititude conditions you have there. I was hoping the log with ETC source would we like the other logs where i can see the transition from limited throttle to WOT and hopefully see the ETC source change.
I should have something to try in the next few days.
I haven't heard of anyone else having this issue, hence i'm leaning towards the low baro influencing the max torque limit.
Chris...
Ok Chris. Anything else I can do to help, let me know. I really appreciate you looking into this.Quote:

Chris, got any update?
Customer told me he drove the car down to roughly 2,100 feet in elevation and it exhibited similar "seat of the pants feelings"
Not too sure if that helps any but that's what I have.
Let me know,
-Rob.
still looking, probably won't have anything until mid next week.
Chris...
looks like it only opens the throttle enough to maintain the Manifold pressure equal to baro level. So if your baro is 84kPa and you want WOT the ECM doesnt open the throttle any more after it sees 84kPa as there really isnt any point if there is no vacuum in the manifold....
Hey Chris tell me a good story!
I'm guessing this was more of a challenge than you expected huh?Quote:

not yet sorryQuote:

We have a 2012 V6 Camaro here with the same problem and from what we can gather it is a MAP/Torque correlation issue. The Torque Model Coefficient Tables (not avail. in HP Tuners) need to be adjusted to allow the throttle to fully open at lower MAP values. We are still working through some of the issues to get this sorted out.
Any news on this?
Any luck with this. my 2012 2LT Camaro has this same issue. I also need a way to increase my fuel pressure command. Any help would be great. I'm on the fine edge of having my car into an 11 second ET if I can keep fuel pressures from dropping below 45psi while on nitrous and causing my low pressure switch to turn off my system. I use HP Tuners Pro Suite. I'm am very new to all of this style of tuning.

:pray: We can just keep hoping.
