Device update in LCU

[HerzKaraya]

Hi fellow hard-core modders,

I have to revisit this topic once again as I´m having some really surprising results in my WiR Mod.
Example:
the 3,7cm Pak upgrades to 5,0cm Pak, then to 7,5cm Pak, finally to 8.8cm Pak (so devices path says)
A LCU starts with 60 x 3,7cm Pak assigned, let´s say I want it to upgrade normally and have a final amount of 40 x 8.8cm Pak.
Should I set the TOE for this unit at 40 x 3,7cm Pak, or 8,8cm Pak? Does it make any difference, given the path is set?
Does the unit need to suffer losses to reduce it´s amount of available Pak below 40 for the upgrade to come into effect?
Is there a dieroll for a successful upgrade (besides supplies,...)?
Of course, it´s imperative that a unit´s start TOE and final (or "turn to") TOE list the same types of device in same-numbered slots.

I have reached 1944 and still have Pz38s and BT5 in some Panzer/Tank units, same issue as ATG.

Surprisingly also some ShaP still fly I-152´s having more than 2000 Il-2s in the pool to upgrade to...

Your help is appreciated!!!!

You are very limited in WITP. If 37mm upgrades to 88mm it will have same TOE number you choosed, you can't vary it, the only way to somewhat manage it is to reduce the number of 88 being made compared to 37mm.

Your last issues something is wrong or you lack supply/HQ range to make upgrade work.

My testing in WitR
Upgrades (converted) weapons land units , examply 3,7cm PaK / 5,0cm PaK really function after 1.7.1941.
After this date no problem.
