I don't see the throttles closing in 5th and 6th but you have to remove the speed restriction that's what's closing them down.
That was my intention. Is your use of Power Commander over Tune Ecu due to just personal preference or have you found the Power Commander better able to deal with boost?

Don’t know if you’ve seen this:


Posts 402&403 and previous ones by Treeman, who did Carpenter rebuilding. Apparently the throttle plates close down at 6000 rpm even with the etv set at 100%. At WOT in 4th on the dyno you wouldn’t be at the speed limit, no?

Penner said that the high end fueling is fine with etv=100% and he hasn’t added fuel above 4000 rpm and TP above 41.7%.

Regarding the rev limit, you can’t raise the rev limit above 7400 for the R and GT models and my understanding is that you need the pro version of tuneecu (300 euros) to do it.

As for getting rid of the speed limit, you should be able to go into parameters and uncheck the speed limit box. Not sure if this option is included in the pro version but in the standard version, there should be an “OPT” button next to the speed limit box with which you pay 49 euros and it lets you uncheck the box. The instructions are on tuneecu.fr. These instructions say you download a stock tune in the Tuneecu app and make the change in this tune before uploading to the ecu. It isn’t clear if you can do this on a custom tune like Penner’s which you have stored in your Android device. One would think so but I would consult Alain directly or Tom Tomtom on Facebook.

Regarding the lambda sensor(s), you can remove them and uncheck the O2 sensor box in Tuneecu to suppress error codes. Same with the SAI system. Both of these are unnecessary on a hot rod.
