Hi Alex, it's HIGHLY UNLIKELY that the Max is at fault, especially with respect to the RPM feature, so before you do anything further in that regard, might I suggest you give Lewis or Dave a call, to ensure you everything correctly set up and connected.
Similarly the AFR should NOT be a problem, as long as the correct settings are selected, so again I'd suggest a quick chat with lewis or Dave on that one as well.
The reasons I very much doubt that the Max will be at fault in these regards are;
1) We've NEVER had a Max fail in ANY specific way as you're anticipating
2) As far as I'm aware the Max has the ability to work with every type of AFR unit
3) we often encounter situations like this and yet we've always found the problem to be something other than 'A FAULT' with the Max
Sorry I can't give you absolute answers to the issues but I delegated the donkey work of creating the Max to one of my EX employees and unfortunately he was the only employee who had FULL knowledge of all aspects of the Max features. Since he left the 3 of us Dave, Lewis and myself have been trying to learn the knowledge we are missing (while also learning about the new features I've added in the years since he left), to ensure we can provide the guidance customers require.
In most cases Lewis has the greater level of knowledge but thankfully the knowledge they both have isn't the same, so between them they can usually provide the assistance required.
Unfortunately, Dave doesn't work Tuesdays so if Lewis can't assist you, you'll have to wait until Wednesday, which hopefully won't be too much of an inconvenience.
I've sent emails about my issues about the AFR with no response as of yet. I'll call tomorrow and find out the info about the Max set up issues. It's merely my frustration and having to burrow myself under the car after dicking around under the bonnet for hours had me infuriated.
I also HIGHLY doubt that there is something wrong with the unit itself, I just need to find the means to TEST the rpm feature.
Also, no matter what I did with the pot on the Max for the input signal. I still think that it's the AEM sensor output scaling. It's too bad that there isn't anyone on here that has a resolution for this because I've searched the forum high and low.
BTW, the issue with the misfire was actually the OPPOSITE of my earlier findings, in that the car DUMPS endless fuel at the top end. I mean it's a LOT of fuel, so I need the AFR loop to take away the excess fuel. Furthermore, the excess fuel in the tune is to take away heat due to the 23 psi of boost spike that the car makes and 29 psi boost spike on 25 shot of the gas!
What's funny is when I did the shutdowns during the misfire to see what the plugs showed, revealed a rich mix but not a SUPER rich mix like the AFR meter is reading.
