hi Guys,

I'm wondering which options there are for a TCU tune for the 45e Hybrid, since xHP doesnt offer a tune for this model....

Has to be compatible with MHD

I have contacted a local tuningshop and they offered a solution for me, also they stated that its very wise to tune the TCU when the engine is tuned because without it the ECU needs to do something called "torque bending" to fool the TCU about the actual load it receives.
But because the clamping pressure isnt raised the clutches are actually wearing out faster.

Also the oil temp is regulated better when tuned.

And who is the tuner offering this,what xHP is unable to do for technical reasons?
By the way, “torque bending” only becomes relevant if you want to go above 800 Nm of torque. That’s roughly where the gearbox limit is.

How is the TCU tune doing? Are you launching with it? I'm running stock TCU with stage 1 MHD. Scares to crap out of me to do much of anything in first two or three gears... so I don't.
note: Have downpipe. Haven't installed because what's the point if I can't have fun in stage 1.
