Throttle closes at 7k rpm, 2014 Coyote with Roush Strategy

[jeffmiller351]

Anyone take a look at the tune and datalog to help troubleshoot 7k throttle reduction from WOT? Runs pretty good otherwise, but haven't been able to find the limiter here.

Upload a better log with more PID's. Attach file in .hpl format.

Man you're going to blow that motor. The second pull never goes into PE and you're going all out to 7600 at idle lambda.

Change your PE throttle threshold. Lower the first cell to 70% throttle and curve it down to 30% at 6500.

What are your mods? What throttle body do you have?

You're hitting a torque limiter, Torque Management > General > ETC Torque Max needs increased. Also in the same tab, set the oscillation switch to disabled.

Thanks for pointing out the PE and Torque limits. I'll make the changes and re-log with the PIDs from Sirius and respond back. This is a 2.9 whipple rear feed with VMP Twin Jet 67mm TB.

you cant have your driver demand like that

This may not be the case here, but I have seen instances where with the Flex Fuel logic disabled, it will still reference the FFV Wot Lambda table, so just as a precaution copy over your non FFV Wot Lambda values.

Believe or not this trick actually works quite good...

as for the limiter:

torque limits yes, driver demand no it may drop you out of PE

I cant agree on this one sorry.
