Forcing N54 to shift at redline …xHP doesn’t seem to make it happen

[pbondar]

With the TTE500 hybrid turbos the N54 engine now wants to rev to the redline..previously it was a waste of time as power fell off well before 7,000 rpm.

I’ve set xHP to shift 3,4,5 at 7k...in all modes

However I notice when doing 3rd gear pulls and 5th gear dyno runs that the DCT box shifts around 6,650-6.750

Is there a way to force it to shift at 7k to eek the last few rpm?

Or is the TCU/DME saving me from any follies?

Manual mode and paddle shift ?
Have you contacted Xhp ?

Yes all modes same result ..D S M…not asked xHP..thought I’d ask here first?

it’s suggested that the shift logic is not that accurate..may try asking for 7,200 and see what gives?

I have mine set to max on manual mode. Zero issues.

Max bring 7,000 rpm?

I think it max out at 7100rpm for 6 AT.

What is the best shift speed for dct? I'm single turbo. Want to get the fastest 1/4 mile. At present, M xhp is set to 7200rpm, but it seems disobedient. He will automatically change gears at 7000rpm.

6at let the shifts be pulled up to 8100rpm if needed.

Dme max rpm is 32x255 so 8160rpm is dme maxxed out.

For manual mode with no auto upshift this is what I run

Do need to rev the ecu rpm restriction? What is the best actual gear shift rpm in manual mode? 7300 or 7500？When you do the 1/4mile test, how many rpm will you shift?（single turbo，28psi，stock engine），thanks
