E38 Hard Limits? Hitting a brick wall at 7059RPM???

For diagnostic purposes I have turned off the rev limiters, torque management, speed limits, maxed out the diagnostic parameters for MAF, MAP, ETC and right at 7059rpm the engine hits a brick wall. The car is currently in maf only mode making 657RWHP on my MD

Any thoughts?

How is it limiting? Fuel, Spark, ETC?

normal first response.... post a log and the tune.....

[Meister]

I will shortly.....it is ETC related. I have turned off EVERYTHING I can

[GMPX]

Are you seeing the throttle position close when it hits the limiter?

[Meister]

I will post up the log....yes, right when this happens the throttle seems to be closing. With the delays in the logs it may be right when I do lift off.

Sounds like TPS vs airflow rationality checks may be coming in to play. Are there any DTC's ?

No DTC's. Where is the TPS .vs. airflow setting? I may have already maxed this all out

[swingtan]

C0803, C0804, C0805, C0806

these will trigger "reduced power" mode, especially on throttle close.

That is what I thought.....those are all maxed out. This happens before lifting off the throttle. I stay in it and the engine just hits a brick wall. See the end of the run. This is with rev limit and everything else removed. Right at the end you can see it hit a brick wall while I am still on the throttle. Look at the other ETC values as it seems the throttle is closing
