I was having the same problems. I started a thread called ‘IRMV again’. The bit of advice I got solved it for me. It was my blunder. I use a T16000m and the 4 way ‘Chinese’ hat switch does not have a ‘depress’. I was reading it as aft, instead of down. I allocated another switch for sss depress and it all fell into place. Understanding how the sensors work together is tricky but vital. Anyway, probably not helping you. IRMVs are easier with the DMT but more satisfying with the TPOD, as it takes more skill. Watch a bloke called ‘Overkill’ on YouTube. ‘Deephack’ has started a AV8b series on YouTube, he hasn’t got as far as IRMV yet but he’s got a clarity of his own.
Going from tpod to IRMV, you will need to sss depress x2 before you sss fwd to switch it to IRMV so you can tdc depress to get a lock. Alphabet spaghetti
